Dusk Mane Necrozma, Dawn Wings Necrozma, and Ultra Necrozma debut in Ultra Sun and Ultra Moon

If Solgaleo and Lunala were mysterious, and the Ultra Beasts were an enigma, then Necrozma is a mysterious enigma. A pitch-black Psychic type, it absorbs light for sustenance and can refract it as devastating lasers. Although it resembles the Ultra Beasts, it has many deviations from them. Some say that it came from another dimension ages ago and has slept underground ever since, at least until the Ultra Beast invasion.

The truth is, Necrozma is akin to an Ultra Beast, not unlike the Cosmog line, but was hailed in the distant past as a deity known as "the Blinding One", as it would share light with the ancient populace of Ultra Space and Alola. Yet in the present, it's far from generous; in fact, it's vicious, savage, and one of the few Pokémon to come close to being full-on evil, as it steals light from worlds and devastates areas with its lasers. The reasons behind its apparent change in personality — and the true meaning of its original moniker — make themselves clear over time.

As is tradition with third members of Legendary trios, Necrozma gained new formes with Pokémon Ultra Sun and Ultra Moon, and like Kyurem before it, it absorbs Solgaleo or Lunala to combine with them and use their powers. By absorbing Solgaleo, it becomes Dusk Mane Necrozma, and Lunala transforms it into Dawn Wings Necrozma. It also has a special Z-Crystal of its own, and through it, it can use a technique called "Ultra Burst" to unlock even more power...

A-F

• Abled in the Adaptation: In the games, Necrozma has a Game-Breaking Injury, preventing it from remaining in its true form outside of a brief period, and even then it needs to absorb a Solgaleo/Lunala first. In the Sun and Moon anime, this injury seemingly doesn't exist, and it can remain in its Ultra state almost indefinitely once given ample amounts of Z-Power, without the need to absorb the Sunne or Moone Pokémon. It probably helps that the cause of Necrozma's injury in the games was Adapted Out of the anime.
• Aborted Arc: Sun and Moon suggest Necrozma came to Alola long ago, only to be somehow buried under Ten Carat Hill for hundreds of years before later reawakening. If there was meant to be anything more to this plot thread, it's not in Ultra Sun and Ultra Moon, which retcons it away completely.
• Aliens Are Bastards: It hails from Ultra Space, is abnormally cruel and vicious (if not full-on evil), and is the Big Bad of Pokémon Ultra Sun and Ultra Moon. To be fair, it wasn't always so bastardly, and its current demeanor comes from the ancient people of Ultra Megalopolis crippling it in a bid to control its power.
• Ambiguously Evil: Necrozma has a violent disposition and a habit of shooting lasers all over the place, and in Pokémon Ultra Sun and Ultra Moon, it becomes the Big Bad by capturing Nebby and attempting to steal Alola's light afterwards (and this is after it tried to do so in the past). At the same time, however, Necrozma is constantly in pain thanks to the ancestors of Ultra Megalopolis severely injuring it back when it was more benevolent, and it steals light to survive as it's the source of its power. If nothing else, it’s definitely the most antagonistic a Pokémon has been portrayed in a main-series game so far. Official sources, however, claim on the matter that it depends on one's perspective.
  Kazumasa Iwao: In Necrozma's case, depending on your perspective, you may think it's evil, but in other point of view it may be not.
• Ancient Evil: Five hundred years prior in Ultra Sun and Ultra Moon, it sought to steal the light of the Pokémon universe for itself, but was fought off by the Tapus and Solgaleo/Lunala.
• Animated Armor: Necrozma's base form is its true form's prism armor, rearranged into a somewhat coherent body and animated through its prism brain. When it possesses and fuses with Solgaleo or Lunala, it rearranges its body into a suit of armor worn by its host.
• Another Dimension: Like Cosmog, it was thought to have come from another world several years in the past. Ultra Sun/Ultra Moon reveals that it's an Ultra Beast just like the Cosmog line, even if Beast Balls aren't any more effective on it than on regular Pokémon.
• Anthropomorphic Personification: Each of Necrozma's forms seems to personify cosmic phenomena. Its base form, which is all-black, absorbs light, and is the result of its original form's light disappearing, represents dead stars such as black dwarves or black holes. Dusk Mane and Dawn Wings Necrozma, however, seemingly represent a solar/lunar eclipse. And Ultra Necrozma is a perfectly healthy star that emits light.
• Anti-Frustration Features: In Pokémon Ultra Sun and Ultra Moon, Necrozma's catch rate goes from the Legendary standard of 3... to 255 (for point of reference, it's as difficult to capture as a Caterpie). Granted, the fact that you encounter it after you defeated it in its One-Winged Angel form, and find it in such a sorry state that you need to share light from your Z-Ring just to bring it back to consciousness, probably explains why that's the case.
• Anti-Villain: Necrozma steals light primarily to keep itself active, as well as to soothe its endless physical pain and regain its long-lost light, even if only for a moment. It's ambiguous if it cares much about leaving worlds in darkness or forcibly assimilating sapient creatures to do so, but well-intentioned goals or not, it makes Necrozma a threat to multiple universes as a result.
• Armored Dragons: Its true form, Ultra Necrozma, is one of these, wearing prism armor over its body of pure light energy. After the loss of its light, all that remained of Necrozma's physical form was its armor, which its brain prism animates telekinetically to act as an improvised body.
• Artistic License – Physics: Light, like all energy, moves from areas of high concentration to low concentration, and unless the source itself is removed or completely drained, continues to flow indefinitely. The idea that Necrozma would be capable of permanently stealing all natural light in an area would defy all known laws of the behavior of energy. Justified in that Necrozma is an Eldritch Abomination capable of defying most common understandings of science.^note Also, it's implied that the light stolen by Necrozma eventually escapes its body due to the Game-Breaking Injury that forces it to steal light to stay alive in the first place, so it's a bit less physics-breaking than it appears at first glance.
• Ascended Extra: Like all third Legendaries (who aren't Zygarde), it started off as an Optional Boss in Pokémon Sun and Moon before receiving new formes in Pokémon Ultra Sun and Ultra Moon. Unlike most however, who tend to be the Big Bad's new toy or a surprice ally, Necrozma is the Big Bad of the Ultra games itself.
• The Assimilator: To achieve its alternate formes, Necrozma absorbs Solgaleo/Lunala and takes control of their body, while its own covers them like armor. It even gains access to the pair's typing, signature moves, and their exclusive Z-Moves.
• Astonishingly Appropriate Appearance: The Pokémon's name means 'Death Black Prism' and Necrozma itself is black, steals light, and is possibly related to the extremely dangerous Ultra Beasts. It also has a star pattern on the back of its torso, giving credence to the possibility that it is partially based upon black dwarfs or black holes (the latter of which light can't escape from), both of which are functionally dead stars. Fittingly, Necrozma was once a dragon shimmering with light, only for it to lose its true form and become the more familiar light-hungry black prism creature.
• Attack Its Weak Point: This is always a major part of Pokémon gameplay, but Ultra Necrozma takes this a step further by having the exclusive abilty Neuroforce, which further increases the damage of super-effective moves by 25%, like a stronger Expert Belt.
• Awesome, but Impractical: Prismatic Laser is essentially a Psychic-type Hyper Beam with 10 more power and 100% accuracy, which functions well with its STAB. Unfortunately, it also retains Hyper Beam's recharge requirement after using it. (Presumably, you are expected to keep Photon Geyser over it, as its Z-Move is tied to it).
• Ax-Crazy: According to the Pokédex, its disposition is incredibly violent (something pointed out for only a few Pokémon like Mewtwo and Hydreigon), and its habit of shooting devastating lasers all over the place may be a result of such. It's no better when devouring Solgaleo/Lunala's light; both forms have colorful Pokédex entries detailing how Dusk Mane/Dawn Wings Necrozma rips foes apart with its claws, while Dusk Mane Necrozma is noted to be ferocious and impossible to control. It's eventually revealed that its true nature is much more benevolent, but a horrible injury it suffered in the distant past has left it in a state of constant rage, hunger, and pain.
• Bat Out of Hell: Dawn Wings Necrozma becomes one using Lunala, only it looks even more hellish thanks to its new color scheme, black armor, and Glowing Eyes of Doom.
• The Battle Didn't Count: Even when causing a Legendary Pokémon to faint previously put an end to their imminent threat (such as with Kyogre/Groudon, Black/White Kyurem, and Ultra Necrozma later on), defeating Dusk Mane/Dawn Wings Necrozma at the Altar of the Sunne/Moone causes it to simply fly back to Ultra Space with Nebby in tow, and none the worse for wear.
• Beam Spam: Its Secret Art, Prismatic Laser, which involves it firing a shining laser into the crystals on its arms, which then refract into a rain of deadly rainbow-colored lasers.
• Became Their Own Antithesis: Before losing its light to the ancient city's greedy citizens, it was happy to share its light across Ultra Megalopolis, Ultra Space, and even Alola itself. Afterwards? It outright steals the light of numerous worlds to satiate its endless hunger.
• Being Tortured Makes You Evil: The Blinding One was a benevolent and generous deity, but in their attempts to take its power for themselves, the ancient people of Ultra Megalopolis gave it a Game-Breaking Injury that left it depowered and reliant on draining light to survive, giving birth to the vicious and rage-filled prism monster Necrozma.
• Big Bad: Of Pokémon Ultra Sun and Ultra Moon, taking the mantle from Lusamine, with it capturing and absorbing Nebby to transform, attempting to "steal Alola's light", and succeeding in stealing that of Ultra Megalopolis, with the implication that it covered Alola in darkness in the past and was defeated with Solgaleo/Lunala's light and the Tapu's power. However, it is also said that its behavior was induced due to the ancient inhabitants of Ultra Megalopolis causing it to lose a part of its body when they tried to take control of it. Before this, it was a benevolent god who shared light with everyone rather than stealing it away.
• Big Eater: Of light, which is what it needs to survive. How much is it willing to absorb at a time? Only an entire universe's worth. And if its cry of "Lie... Lie... Liiight!" as Ultra Necrozma is anything to go by, even when it's absorbed enough light to regain its original state, it only wants more. It's also shown in its Z-Move when used by the player. Of all the Z-Moves in the game, it's the only move that leaves the protagonist clearly exhausted even before the move is used, indicating that it takes an intense amount of energy beyond that of other Z-Moves to power.
• Bishōnen Line: Transforms from the bizarre base Necrozma to the more majestic but still chaotic-looking Dusk Mane/Dawn Wings Necrozma to the graceful, draconic Ultra Necrozma.
• Bizarre Alien Biology: According to its concept sheet, its "torso" is actually its head, and the prism-like object is actually its tail. This is because its torso piece serves as the head of its "true" form, Ultra Necrozma. Its "brain", meanwhile, is a multicoloured triangular prism◊ animating a set of armor, and it can completely disassemble and rearrange it in different ways to fuse with Solgaleo/Lunala with no harm to itself. Said prism not only implants itself into the host, but also extracts itself from there to become Ultra Necrozma's head. Finally, looking at the differences between Necrozma and Ultra Necrozma makes it clear that Necrozma's arms are actually its feet attached to its lower set of wing bones and its legs are its upper set of wing bones.
• The Blank: Although Necrozma appears to have a face with a defined (if static) set of eyes and features, this is really a completely faceless prism with coloured pieces scattered inside of it. Its tail and head obscure the top and bottom parts of it, but if you look closely, you can make out Necrozma's "face" on it.
• Blood Knight:
  • Necrozma is explicitly described as having an incredibly violent disposition and constantly firing lasers all around it, though it's unclear whether it enjoys destruction or not. The Pokédex entries for its Dusk Mane/Dawn Wings formes are a little less ambiguous; it doesn't pull its punches in fights.
    Ultra Sun: This is its form while it is devouring the light of Solgaleo. It pounces on foes and then slashes them with the claws on its four limbs and back.
    Ultra Moon: This is its form while it's devouring the light of Lunala. It grasps foes in its giant claws and rips them apart with brute force.
  • The first thing Ultra Necrozma wants after its restoration is a fight, with the narration saying that "it seems eager to to battle".
• Body Horror: Dusk Mane and Dawn Wings, at least from Solgaleo/Lunala's perspective. Hard to argue when your mind and body is completely taken over by Necrozma, and when an Ultra Burst prompts it to fully consume you to regain its true form. Even its regular form has shades of this, as it seems to be an attempt at a coherent body when Ultra Necrozma's light is gone and only its prism armor remains. For the record, its torso is made out of Ultra Necrozma's head, its "tail" used to be its chest, its legs were Ultra Necrozma's top wings, and its arms are formed by taking its original feet, attaching them to its lower wing bones, and sticking them into its former eye sockets. Jeez.
• Bragging Rights Reward: In Sun and Moon, barring Elite Four rematches, there's very little Necrozma can be used on after you're able to catch it, owing to its restricted use in the Battle Royal/Battle Tree, so it's a sign of completion more than anything. Subverted in Ultra Sun and Ultra Moon, where you can catch it before the Pokémon League and complete Episode RR afterwards.
• Breaking Old Trends:
  • Until Necrozma came along, no Legendary Pokémon was the Big Bad of a core game. At worst, they were merely powerful obstacles to be faced due to the actions of the real antagonist or a last minute ally, but they had no agency or plan of their own (at least, not beyond what the antagonist wanted to use them for).
  • Prior third-version Legendary Pokémon had personal connections and design similarities to the initial duo they were paired with, and could be considered "siblings" or "masters" to them.^{In order...}Rayquaza calms Kyogre and Groudon's rampages, Giratina was created alongside Dialga and Palkia, Kyurem is what remains of the original dragon Zekrom and Reshiram split off from, and Zygarde maintains the balance between Xerneas and Yveltal's abilities. Not only does Necrozma's design have nothing in common with Solgaleo and Lunala, but they're not even directly related.
• Broken Angel: It's strongly implied to have been the benevolent God of Ultra Space (or at least the dimension where Ultra Megalopolis is) and accordingly worshipped as such... only for the humans from there to stab it in the back and attempt to enslave it. It went sideways when all they managed to do was to horrifically mutilate Necrozma. The bizarre prism form first seen in Sun and Moon is the result of Necrozma rearranging the few remaining pieces of its body into something resembling a cohesive shape after the injury and the loss of its light due to its betrayal at the hands of the Ultra Megalopolis' ancestors.
• Cartoon Creature: While Solgaleo and Lunala resemble real-world animals, Necrozma seems to be a completely original design, though it does have some draconic elements to it, such as claws and a dragon-like head (which is what you'd think is its torso). When we finally get to see its true form in the Ultra games, its more obviously an angelic dragon.
• Cast from Stamina: Its signature Z-move "Light That Burns The Sky" drains so much vitality from its trainer that they slump in visible exhaustion after performing the usual dance, something not seen in any other Z-move animation. It doesn't actually drain or injure the player or Necrozma though, it's just the animation.
• Casting a Shadow: Much as Solgaleo and Lunala can become a beam of light, Necrozma is shown in Ultra Sun/Ultra Moon to be able to turn into a beam of black darkness. Official materials also state that Dusk Mane/Dawn Wings Necrozma can use its split tail to propel itself forwards using black light.
• Charged Attack: Necrozma learns Stored Power, a move that increases in strength depending on the number of stat boosts that the user has. Given Necrozma's good bulk, ability, reliable recovery, and wide variety of status buff moves, it can use Stored Power to great effect. Not as useful in its Ultra Form however, as it loses Prism Armor and quite a bit of bulk from its Dusk/Dawn forms in exchange for insane offense, and it can't waste much time setting up.
• Climax Boss: The battle with Ultra Necrozma takes place where the final battle against the villainous team boss would happen in other games. Once Necrozma is stopped, Lillie and Lusamine leave to nurse Nebby back to health while Guzma leaves on his own, leaving the main plot solved — the player, however, still has to complete the Island Challenge.
• The Computer Is a Cheating Bastard: When fought as the Climax Boss, Ultra Necrozma knows Dragon Pulse and Smart Strike, both moves that it can only learn through Move Tutor and TM (respectively), and not as level-up moves. It also isn't holding its Z-Crystal.
• Confusion Fu: Not to the extend of fellow God Arceus, but its movepool is still absolutely huge (it's shared across all 4 of its forms save a couple of unique move for the fused ones) and it can viably run dozens of different sets. Just seeing an opponent with a fused form doesn't even remotely guarantee it will use the Ultra form at all (which radically changes its role in a fight) so it's very difficult to predict what is it going to torture you with.
• Contractual Boss Immunity:
  • Like Full Metal Body and Shadow Shield, Prism Armor is unaffected by Mold Breaker and similar effects. Prism Armor is also not ignored by Solgaleo, Lunala, and Necrozma's signature moves and their exclusive Z-move variants.
  • When it absorbs Nebby at the Altar of the Sunne/Moone in Pokémon Ultra Sun and Ultra Moon, it can't be captured, nor can it be captured when it becomes Ultra Necrozma at the top of Megalo Tower and moves that would otherwise end a wild Pokémon battle, such as Roar and Dragon Tail, will always fail. Both times, you're forced to defeat it.
  • Subverted doing its final Climax Boss showdown in its true form. It comes with a bunch of insane boosts on top of already having Godlike stats (literally, its stronger than Arceus), but it does not have any sort of status protection. If you manage to poison or burn it the fight might as well be won so long as you can stall a bit (which is easy with revives and the like), that being said, its speed, offense and movepool are so overbearing that just landing that status condition is very difficult in the first place. If you can paralize it its speed is sharply cut too, so you can actually land hits on it before it one shots whatever you send out against it.
• Contrasting Sequel Antagonist: The fact that Necrozma's the first Big Bad in the series to be a Pokémon rather than a human presents a prominent contrast between it and the series' prior villains. Its other prominent contrast to every villains in the predecessor games is that Necrozma is not controlled by a human through any means, who is instead acting on its own will.
• Cosmic Entity: In the past, Ultra Necrozma's scope was such that its light illuminated The Multiverse, and even today this light pours out of Ultra Wormholes and can be harnessed as Z-Power. Necrozma's power has greatly diminished from its glory days thanks to its unhealing wound, though it can temporarily regain its true form via Ultra Burst.
• Crystal Dragon Jesus: In its native universe, it was once regarded as a benevolent deity that provided the light of its universe. The form it took is also literally a crystal dragon. In the present day, however, it is no longer worshipped as it lost its light, and was in fact feared as a demonic "pillager of light" in ancient documents.
• Cutscene Power to the Max: In order to fuse Solgaleo/Lunala with Necrozma, the player needs to use the N-Solarizer/N-Lunarizer on the two. When Necrozma absorbs Nebby in a cutscene, however, all it needs to use is its hand.
• Dark Is Evil: Pokémon Ultra Sun and Ultra Moon's promotion plays Necrozma up as a villain, with it kidnapping an evolved Nebby, mentions of it being out to steal Alola's light, and the implication that a period where Alola was covered in darkness was directly caused by it. It's even established to have more "darkness" abilities. And of course, Necrozma's disposition is noted by the Pokédex in Moon to be incredibly violent (and considering how all Pokémon are Blood Knights by nature, that distinction likely means a lot). The "evil" part may be a little debatable, but it's still not a Pokémon to piss off.
• Dark Lord on Life Support: Thanks to the Abusive Precursors of Ultra Megalopolis mutilating and destroying its ability to generate light, Necrozma sustains itself through pilfering the light of other universes and/or Solgaleo and Lunala. If it doesn't get enough light, impurities build up within itself and becomes comatose
• Defeat Means Friendship: Necrozma's the first Big Bad to be a wild Pokémon, but like all such Pokémon, it's a slave to gameplay mechanics and can be captured after its role in the plot is served. Although in this case it makes a certain degree of sense, since capturing it happens after you share the light of your Z-Crystals and Z-Ring with it in order to heal it. Its capture rate is also sky high and it barely puts up a fight, meaning it most definitely wanted to.
• Depending on the Writer: Although the games and most official media depict Ultra Necrozma as its true and original form that it lost after a Game-Breaking Injury, an interview with Ultra Sun and Ultra Moon's director Kazumasa Iwao instead purports that the form is the result of Necrozma absorbing far more power than it ever needed and going berserk, akin to Eternamax Eternatus. Said interview also claims Necrozma stole light from Solgaleo and Lunala across Ultra Space in a symbiotic cycle long before it came to Ultra Megalopolis or Alola, a relationship that is never brought up in any actual media.
• Depth Deception: Even though Necrozma appears to have a face made of various colored shapes, the pre-rendered depiction of its brain prism◊ on Ultra Sun and Ultra Moon's title screen shows the shapes are more haphazardly placed inside it, and only from certain angles does the "face" show up. The in-game model, on the other hand, simply uses textures to depict the shapes, making it more easily visible.
• Dimensional Traveller: Like Solgaleo and Lunala, it can open Ultra Wormholes at will to travel across dimensions.
• Discard and Draw: Upon transforming into Ultra Necrozma, it discards its Prism Armor Ability for Neuroforce, which essencially its exact opposite. Prism Armor reduced the damage Necrozma takes from super effective moves, while Neuroforce increases the damage it deals when hitting supereffectively. Necrozma also loses a significant amount of bulk compared to its Dawn Wings/Dusk Mane forms upon hitting Ultra, in exchange for an astronomical boost to its offenses and speed (which is a significant net gain mind you). The lost is not that severe though, Ultra Necrozma still sports a moderately durable 97/97/97 defenses, but in the uber tiers where its allowed, it can't stay fighting for too long.
• Dishing Out Dirt: In addition to naturally learning Stealth Rock, Rock Blast, and Power Gem, it can learn Earthquake and Stone Edge with a TM/TR, Rock Slide with a TM, Earth Power through a Move Tutor/TR, and Meteor Beam through a Move Tutor. And because of Necrozma's stat distribution and wide variety of Status Buff moves, it is among the very few Pokémon who can viably make use of all of these moves.
• Draconic Abomination: Necrozma's true form is very recognizably a winged dragon. However, it's still very much an Eldritch Abomination. Its head, chest, arms, lower wingbones, and feet are made of prisms, while the rest of its body seems to be made of light, judging from its mass compared to base Necrozma, which it generates by fully consuming Solgaleo or Lunala.
• Dragons Are Divine: Its true form Ultra Necrozma, aka the Blinding One, is regarded as a deity within Ultra Space.
• The Dreaded: Necrozma's invasion of Alola in the past caused it to pass into legend as an evil darkness that the region valiantly repelled, with folklore suggesting the Kommo-o line have trained themselves to fight against it. The postgame of Ultra Sun and Ultra Moon shows that the king of Alola at the time had all books talking of it burned so the populace wouldn't live in constant fear of its potential return.
• Driven to Madness: The reason for Necrozma's unusual level of violent craziness and insatiable desire for light? It's in constant, unending agony thanks to its body being broken by the ancients of Ultra Megalopolis long ago, and the only way to soothe itself, if only temporarily, is through absorbing and stealing light. Even absorbing Solgaleo/Lunala and Ultra Bursting back into its true form is not enough to fully rid itself of pain.
• Downer Ending: Necrozma's own life story is pretty awful, being a fallen God stuck in a state of unending agony as a result of humans mutilating it and attempting to steal its power. Ultimately, it has to be subdued by force because it has grown too mad and violent. By the time you get to catch and befriend it, its in such a sorry state its half dead and comatose. And you can't heal or restore it in permanent manner, it finds a bit of confort being close to the Z Crystals (which are said to be parts of its body) and at best you can let it return to its original form, but it can only hold it for a brief moment and for that to happen Necrozma has to possess Nebby which in turns leaves Nebby in an awful state.
• Eldritch Abomination: Its true self seems to be a crystalline prism which usually appears as its eye, while its body seems to be made off of a prism-like armor that can reconfigure itself with no harm done, even assimilating Solgaleo or Lunala. Its original body also includes a copious amount of Hard Light. And, for the record, it is less alien to the Pokémon world than the Ultra Beasts, to the point that Poké Balls do not recognize it as an Ultra Beast.
• Elemental Baggage: Averted; unlike Solgaleo and Lunala, Necrozma can't generate light on its own (at least, not anymore). Instead, it steals light from its surroundings and uses it to fuel its attacks.
• Elemental Rock-Paper-Scissors: Ultra Necrozma's ability Neuroforce takes this trope even further by increasing the power of super-effective attacks against the opponent by 25%.
• Energy Absorption: Necrozma absorbs light to both sustain itself and fuel its attacks, as it is incapable of generating light by itself. By fusing with Lunala and Solgaleo, it forces them to continuously emit their own light, which it then absorbs into itself.
• Energy Beings: Ultra Necrozma, as its transformation during an Ultra Burst shows, is made up entirely of light held in a cohesive shape by the prisms comprising its base form's body.
• Extra-ore-dinary: Dusk Mane Necrozma is part Steel-type, and can use Solgaleo's signature move, Sunsteel Strike. It can also learn Mirror Shot and Metal Claw naturally, and Gyro Ball, Iron Head, Flash Cannon, and Smart Strike through TM, TR, or Move Tutor.
• Evil Counterpart: Being an ill-tempered all-black prism that steals light and causes darkness, Necrozma acts as this to Solgaleo and Lunala, both of whom are brightly colored, motifed with gold, emit light, and are benevolent. Likewise, while Lunala's light absorption is treated as The Sacred Darkness, Necrozma's similar ability is treated as a world-ending calamity ("light" in this case seemingly refers to more than just the stuff that makes things visible).
• Evil Is Not Well-Lit: Whenever it shows up, it drains a world's light. Ultra Megalopolis, one such world left without light (and the site where Necrozma was imprisoned/achieves its Ultra Necrozma state), has to use artificial lighting to keep things visible.
• Fallen Angel: Once a revered deity known as the Blinding One, the ancestors of Ultra Megalopolis wound up gravely wounding it in a failed bid to control it, causing it to not only lose its true form, but also be under continuous constant pain. After this, it became the dangerous and violent stealer of light it is today.
• Fantastic Nuke: Ultra Necrozma's Z-Move, Light That Burns the Sky, is effectively this.
• Floating Limbs: Though it's not immediately clear, Ultra Necrozma's wings float independently from the rest of its body, as if held in place by an invisible bit of light.
• Foil:
  • It serves as one to Solgaleo and Lunala. All three come from Ultra Space, and all three use light in specific ways (with Necrozma absorbing light just as Lunala does). However, while Solgaleo and Lunala are benevolent and revered by the people of Alola, Necrozma seems more nefarious, as it outright steals light and leaves worlds trapped in darkness.
  • To Zygarde, The Order Pokémon. Both live underground away from humanity, but their reasons for doing so... are different. Necrozma simply sleeps underground almost all of the time, whereas Zygarde is an active monitor of its home. Necrozma's an outsider to the status quo of the Pokémon world, whereas Zygarde's a native to it and to say they have different tendencies is an understatement: Necrozma is one of the only Pokémon who (seemingly) actively attacks without any empathy, whereas Zygarde only becomes active when nature is endangered. Course it turns out that Necrozma is more maddened by pain and hunger than it is a being that lacks empathy, given in the past it was beloved for sharing light and power with humans.
  • In a way, it acts as one to Kyurem. Like it, Necrozma has a lower stat total and powers itself up by absorbing a Legendary Pokémon it shares a connection with, taking its attributes as a result. However, while said Pokémon literally split away from Kyurem long ago, Necrozma has no familial relation to its partners despite a shared origin in Ultra Space. In addition, while in Pokémon Black 2 and White 2, Kyurem was held captive and forced into Team Plasma's schemes, Necrozma in Pokémon Ultra Sun and Ultra Moon acts completely autonomously, stealing light and capturing Nebby for nobody's motive but its own. Finally, while the Original Dragon — possibly a form of Kyurem — that the Tao trio split from is a Missing Secret, Necrozma's true form appears in-game and is achieved via a Super Mode when fused. Additionally, while the Original Dragon lost its true form by means of willful fission, Necrozma's form was lost unwillingly.
• Freudian Excuse: Necrozma's abnormally enraged and vicious streak stems from the ancient people of Ultra Megalopolis attempting to control it, delivering a crippling injury to it in the process that leaves it leaking light, and this is why it seeks to steal light from other worlds. It doesn't care how much that may hurt people because people didn't care about how attempting to steal its light would hurt it, and it hurt it badly — in Necrozma's point of view, this is to Pay Evil unto Evil.
• Fusion Dance: Pokémon Ultra Sun and Ultra Moon gives it the ability to merge with Solgaleo and Lunala, with parts of its body acting as black armor. Ultra Necrozma is one of the Power Booster variety — apparently, Solgaleo or Lunala has been fully consumed and converted into the light that makes up its body.

G-N

• Game-Breaking Injury: Long ago, the Ultra Recon Squad's ancestors broke off a piece of "the Blinding One" in their avaricious efforts to control its power, causing it to devolve into the misshapen prism monster that steals light from other worlds (light that inevitably leaks out). It can still use Ultra Burst in its Dusk Mane/Dawn Wings form to become Ultra Necrozma, but this only lasts for as long as the battle does.
• Gameplay and Story Segregation: Dusk Mane Necrozma's Ultra Moon Pokédex entry states that it is ferocious and impossible to control... but it will always obey you by the time you will be able to catch Necrozma, since the N-Solarizer and N-Lunarizer are unobtainable until Necrozma is caught, and that can only be done after every trial is completed.
• Gemstone Assault: Uses its crystals to focus light into deadly lasers, and naturally learns Power Gem. However, like most Pokémon that learn Power Gem, it's not a Rock-type at all.
• Giant Flyer: Dawn Wings Necrozma is this because it uses Lunala's body, but more notably, Ultra Necrozma is a towering four-winged dragon. At 24'07" (7.5m), Ultra Necrozma is also the tallest Psychic type.
• Giant Space Flea from Nowhere: Most Legendaries and Ultra Beasts have some sort of forewarning that they will be there and a specific way they're encountered. Necrozma can be encountered in Sun and Moon like any wild Pokémon after capturing all of the Ultra Beasts, with only a vague hint from Looker to its existence.
• Gold and White Are Divine: Necrozma is regarded as a deity in Ultra Space, and it fits the trope while controlling Solgaleo. It truly fits when it becomes Ultra Necrozma, with its entire body turning into a gold and white angelic-looking dragon.
• Golden Super Mode: Ultra Necrozma's prisms turn from black to gold, and the rest of its body is made with glowing yellow light. The in-game model does, however, render the prisms more of a lighter yellow than what the official artwork uses, though this could be because of graphical limitations.
• Glass Cannon: Ultra Necrozma is this compared to other Legendaries. It is by no means frail, but its defense and HP stats are below-average for a Legendary; on the other hand, both its attack stats are quite simply absurd, and is also one of the faster Legendaries out there.
• Grand Theft Me: Its "fusion" with Solgaleo and Lunala is described as it taking over their bodies.
• Gravity Master: Naturally learns the move Gravity, and as a support spirit in Super Smash Bros. Ultimate, Necrozma provides the player with an immunity to gravity changes in battle.
• Guide Dang It!: There is nothing in the game or the promotional materials to hint that Photon Geyser shares Sunsteel Strike and Moongeist Beam's ability nullification, aside from its Z-Move Light that Burns the Sky also having that effect. And it's easy to assume that effect is exclusive to the Z-Move.
• Hard Light: When they become Ultra Necrozma, it seems that most of their body is made of solidified light.
• Heal Thyself: Learns Moonlight and Morning Sun by level^note or rather by Move Relearner, since it's caught past the level where it can learn any moves naturally.
• Heel–Face Turn:
  • Necrozma can be captured and used by the player, and people in-universe hope that the player can help soothe some of Necrozma's constant pain/hunger, as the presence of Solgaleo/Lunala and a large collection of different Z-crystals brings Necrozma a great deal of comfort and stabilizes its mental state.
  • In fact, before it can be captured, the player has to share the light of their Z-crystals to heal it. Necrozma became a villainous force that stole light after greedy people caused it a grievous injury while trying to steal its light, and so it's only fitting that it becomes a benevolent light-sharing creature again after a human shared their light with it.
• Hidden in Plain Sight: Ultra Necrozma has been seen for just as long as Dusk Mane/Dawn Wings Necrozma; either half of its head can be seen on the box art of Ultra Sun or Ultra Moon.
• Holy Hand Grenade: Necrozma's powers all center around light as an element and not a force of "good", but Light That Burns the Sky comes from what is, for all intents and purposes, a Physical God shimmering with life-affecting light. And hoo boy, what a grenade it is.
• Hungry Menace: The motivation for all Necrozma's deeds is its insatiable hunger for light. Due to its injuries, its body cannot contain the light it needs to survive for long — meaning that it can drain entire worlds of light and still never be sated.
• Inconsistent Dub: In two different English trailers, Necrozma has been pronounced as both Neck-ROZZ-mah and Neck-ROSE-mah.
• It Only Works Once: Necrozma can only activate Ultra Burst once per battle, reverting back if it faints in battle. Even if it's revived, it can't use it again. Any other Necrozma in the player's party also won't be able to Ultra Burst if one already did so, even if they meet the criteria.
• Knight of Cerebus: Lusamine is much more heroic and not as as much as a serious threat in Ultra Sun and Ultra Moon, so Necrozma takes it instead. Especially considering Necrozma wants to steal all of Alola's light for itself. To get this point across, Necrozma's first appearance involves it defeating both Lusamine and Guzma offscreen, the then main antagonists, and tossing them through an Ultra Wormhole, and easily absorbing Nebby, after it evolved into the cover Legendary.
• Know When to Fold 'Em: After the player revives it with their Z-Ring's light, Necrozma effectively wants to be captured — with its attempt to steal Alola's light to replace its own foiled, sticking with the player and their Z-Ring/Crystals (and Nebby) is a more beneficial option for it.
• Leitmotif:
  • Necrozma shares "Battle! Solgaleo/Lunala" with... well. In Pokémon Sun and Moon, it's one aspect hinting at it sharing a similar background as those two.
  • Pokémon Ultra Sun and Ultra Moon gives a unique leitmotif to Necrozma: specifically, its Dusk Mane/Dawn Wings formes (used in the battle at the Altar of the Sunne/Moone) which uses an Ominous Pipe Organ.
  • Also from Ultra Sun and Ultra Moon is the battle theme for Ultra Necrozma that mixes in the above two leitmotifs with that of Ultra Megalopolis. It too uses an Ominous Pipe Organ, only less sinister and more heavenly (fitting its angelic appearance and status as a Physical God).
• Light 'em Up: It powers itself up by absorbing light, and its two Secret Arts are Prismatic Laser and Photon Geyser; the former of which generate lasers to attack, while the latter is a giant ball of light that erupts into a... well, a geyser of photons. Ultra Necrozma, meanwhile, is pouring with light, and it has the Z-Move Light That Burns the Sky, which... well, take a guess.
• Lighter and Softer: The Necrozma in Sword and Shield is noted by Peony to still be seeking light to feed on, but it doesn't resort to draining their world of light and is easily pacified by being caught.
• Light Is Not Good: In spite of its dark colors, Necrozma's powers are light-based and it eventually recovers its original golden form through draining the light from the player's world. It's worth noting, however, that Ultra Necrozma used to be benevolent, gifting light to all of Ultra Space and Alola... and then the original inhabitants of Ultra Megalopolis permanently crippled it in their attempts to control it.
• Lightning Bruiser: Though it doesn't start off as this, it can very quickly make itself one with its base form's tankiness and access to Stored Power and several Status Buff moves. It instantly becomes this as Ultra Necrozma, with extremely high Attack and Special Attack stats, and very high Speed, as well as good defenses.
• Lunacy: Dawn Wings Necrozma taps into Lunala's moonlight powers to use Moongeist Beam and its Z-Move counterpart, Menacing Moonraze Maelstrom.
• Mad God: Necrozma was originally a benevolent being worshipped as a god before greedy humans horribly injured it. As a result, Necrozma is in unending agony that's resulted in it being Driven to Madness.
• Magic Knight: It has a great Special Attack and good Attack in its base form, though it learns more physical moves from TMs. Ultra Necrozma evens them both out further at a whopping 167. Photon Geyser exploits Necrozma's aptitude in both stats, as it deals damage based on which one is the highest, and attacks the target's corresponding defensive stat (despite being a Special move by definition).
• Make Way for the New Villains: In Pokémon Ultra Sun and Ultra Moon, it swiftly overshadows Guzma and Lusamine as the story's primary antagonist once it shows up by literally throwing them out of Ultra Space.
• Meaningful Name: "Necrozma" has necro, the Greek word for "death", in it. And as a dragon that was made of Hard Light, only to lose said light, Necrozma is akin to a dead star that has ceased emitting light.
• Mechanically Unusual Class:
  • Its Ultra Burst form is activated the same way a Mega Evolution is triggered, but it requires a specific Z-Crystal to do so. Even if the required Z-Crystal is equipped, Necrozma must Ultra Burst before using its Z-Move.
  • Necrozma's Secret Art Photon Geyser (as well as its Z-Move, Light That Burns the Sky) also qualifies as one, dealing Physical damage if its Attack is higher than its Special Attack, and Special damage otherwise (including from stat changes, such as boosting moves or stat drops).^note It still counts as a Special attack so that it becomes a special Shattered Psyche if powered up by a Psychium-Z or a special Max Mindstorm when used as a Max Move.
  • Light That Burns the Sky is the only Z-Move that is not only restricted to a specific Pokémon, but is also restricted to a specific form of that Pokémon. Only Ultra Necrozma can only use this move. A Dawn Wings or Dusk Mane Necrozma that carries an Ultranecrozium Z and cannot Ultra Burst cannot use Light That Burns the Sky.
• Mighty Glacier:
  • Its base form has well-rounded stats, with an awesome Special Attack, a good Attack, defenses and HP. Its lowest stat is a slightly below average Speed, though it learns Autotomize, Rock Polish, Trick Room and Dragon Dance to boost it.
  • Its Dusk Mane and Dawn Wings forms take this trope even further, having higher defenses, much higher Attack and Special Attack, respectively, but slightly lower Speed.
• Mind over Matter: It is a pure Psychic-type in its normal forme, and it remains part-Psychic when fused with Solgaleo or Lunala, and after using an Ultra Burst.
• Multi-Armed and Dangerous: In addition to Solgaleo's four legs, Dusk Mane Necrozma retains its two big claws as arms on its back. It's also happy to pounce on enemies and slash them with all six limbs.
• My Blood Runs Hot: When it transforms into Ultra Necrozma, its body becomes immensely hot, reaching over 10,000 degrees Fahrenheit. Its claw slashes even cause the surrounding area to melt.
• My Rules Are Not Your Rules: Despite acting very much like a Mega Evolution, Ultra Burst is treated as something separate akin to Primal Reversion, so one can use Ultra Necrozma without using up their Mega Evolution slot. It does, however, require holding Ultranecrozium Z to activate, takes up a "slot" of its own (unlike Primal Reversion), and neither Dusk Mane nor Dawn Wings Necrozma can use Light That Burns the Sky without taking a turn to transform.
• Names to Run Away from Really Fast:
  • When you see a Pokémon that has "necro" (as in, "death") in its name, that should be your first clue it's not very nice.
  • Ultra Necrozma's exclusive Z-Move have names that are not the least bit comforting: Light That Burns The Sky in English, Heaven-Scorching Light Of Destruction in Japanese, and various phrases that contain the word Apocalypse in some other languages.
• The Night That Never Ends: If Necrozma pays a visit to a given world and drains all light from it, this is what it causes. Fortunately, it's only known to have done this to one world (Ultra Megalopolis), and the game never touches on the realistic outcome of a world stripped of all (solar) light.
• No Biological Sex: As with most Legendaries, Necrozma has no gender.
• No Mouth: Its base form lacks a functional mouth aside from a set of shapes arranged to resemble one, on account of its face really being its partially-exposed brain prism (and its real mouth currently working as its chest). Despite this, it's still capable of eating food and treats.
• Non-Standard Character Design:
  • Even among the other Ultra Beasts, Necrozma has a very "out there" design, being an all-black prism with no obvious resemblance to any kind of animal and multicolored triangles peppered across what could be considered its face (though some of them are arranged in a way that makes them resemble triangular eyes). When compared to the opulent and majestic Solgaleo and Lunala, almost nothing about Necrozma's design (not even as Ultra Necrozma) hints at a relationship to them, even though past enhanced-version Legendaries shared design elements and motifs with a given duo. Then again, their relationship amounts to little more than a predator and its prey, so maybe it's appropriate.
  • Its alternate formes are very different from past Legendary formes — at first glance, they look like formes of Solgaleo/Lunala having combined with Necrozma rather than the opposite, and yet Necrozma's the one in control (contrast with Kyurem's formes, both of which were clearly Kyurem itself powered up). They also look a lot more robotic and alien than many other Pokémon, in particular Dusk Mane Necrozma. And Ultra Necrozma wouldn't look too out of place in a Final Fantasy game.
• Noodle Incident: How exactly it managed to find itself buried underground for so long in Sun and Moon is never revealed, and Ultra Sun and Ultra Moon drop that aspect completely, with Necrozma coming from Ultra Space instead.
• Not Evil, Just Misunderstood: Downplayed, Necrozma truly does have malicious intent toward humans. It's just that it turns out there's a pretty justifiable reason for it — greedy humans attacked and damaged it long ago to the point where it's left in perpetual agony due to being unable to hold onto any of the light it absorbs thanks to the injury. So Necrozma does what it does both out of survival instinct and spite toward the race of beings who hurt it so badly.
• Numerological Motif: Like Cosmog's family and the Ultra Beasts, its base stats and the levels at which it learns new moves are all prime numbers. Ultra Sun and Ultra Moon break the prime number motif somewhat, with it learning Photon Geyser at level 50.

O-S

• Olympus Mons: Despite being similar to the Ultra Beasts, Necrozma is considered more of a full-fledged Legendary Pokémon, with a gold Pokédex border, lack of the Beast Boost Ability, and Poké Balls having a normal effect on it (whilst the Beast Ball is near-useless in the original Sun and Moon and much more potent, but still not reliable in Ultra Sun and Ultra Moon). Its base stats, while not as high as the Cosmog line's, are still higher than normal and nothing to scoff at. Ultra Necrozma's stats, meanwhile, are well beyond your typical mascot legendary's standards, and it's regarded as something of a deity in Ultra Space.
• One-Winged Angel: Ultra Necrozma serves as one, as it gains a very powerful exclusive Z-move as well as a Totem aura during the battle against it.
• Our Angels Are Different: Ultra Necrozma has a rather angelic design, with a streamlined golden body and four majestic wings, all made of light.
• Our Dragons Are Different: Ultra Necrozma is a Psychic/Dragon-type that resembles a four-winged European dragon, is made of light and prisms, and transforms from beings that barely resemble dragons at all.
• Oxymoronic Being: It can refract light despite being completely black, reinforcing its otherworldly nature.
• Pay Evil unto Evil: It stole all the light of the world of the Ultra Megalopolis, leaving them desolate and forcing them to use artificial sources, nevermind the fact that said light was gifted to them by Necrozma in the first place, who used to be their benevolent god... until the ancient inhabitants of the Megalopolis attacked it in an attempt to steal its power, which just ended up horrifically mutilating it. Guess what was the first thing it did once it could: it rightfully took its light back.
• Panthera Awesome: Necrozma becomes this after absorbing Solgaleo and becoming Dusk Mane Necrozma. It looks even more imposing thanks to its new color scheme, black armor, and Glowing Eyes of Doom.
• Physical God: In Ultra Sun and Ultra Moon, Ultra Necrozma is referred to as "The Blinding One" and revered as a creature that blessed the inhabitants of Ultra Space and Alola with light. It's one of the very few Pokémon that's revered as an actual deity along with Rayquaza.^*Arceus may have made the universe, but no-one so far has hailed it as a god (at least in the main games), unlike these two.
• Pieces of God: It is revealed that the light given off by Ultra Necrozma is the same light that empowers the Totem Pokémon and Ultra Beasts, as well as the source of the Z-Crystals' powers. More overtly, Professor Kukui believes the Sparkling Stones that Z-Power Rings are made from are parts of Necrozma's body that broke off long ago.
• Playing with Fire: It can learn Heat Wave through a Move Tutor, giving it a means of dealing with otherwise problematic Steel-types.
• Point of Divergence: In Pokémon Sun and Moon, Necrozma's Sun Pokédex entry notes how it apparently arrived in ancient times and wound up sleeping underground. Necrozma's involvement in Pokémon Ultra Sun and Ultra Moon happens because, instead of being dormant underground after arriving in Alola, it fought against its denizens and had to flee.
• Post-End Game Content: It's the strongest Pokémon you can fight in Sun and Moon, and can only be encountered after capturing all the Ultra Beasts. It's also at a frightening high level of 75. Averted in the Ultra games, where it's encountered MUCH earlier and it is in fact the game's Big Bad. You can't capture it while it's still the active villain, but after its final defeat you can find and capture it on Mount Lanakila, 'before' the league. Said capture is laughly easy too, as its implied that it literally wants you to capture it (and you get access to its Ultra Form as soons you do too, so have fun stomping the league flat with a deity stronger than Arceus).
• Power Copying: After fusing with Solgaleo or Lunala, Necrozma gains their typing and signature move (and it can even use their exclusive Z-Moves).
• Power Crystal: Its crystalline body absorbs light to fuel its power.
• Power Glows: When it absorbs light, its "face" and the back of its tail shines a bright white. Its alternate formes are also constantly glowing with light because Necrozma is forcibly absorbing the light emitting from Solgaleo and Lunala's bodies. Notably, Ultra Necrozma's prisms are always a shining gold, but its defeat causes them to go back to their original black color. In the shiny forms, Dusk Mane and Dawn Wings Necrozma emit pink light as opposed to yellow and blue, respectively, while Ultra Necrozma emits silver and bluish-white light instead of gold and light yellow.
• The Power of the Sun: Dusk Mane Necrozma, as a result of absorbing Solgaleo, gains access to Sunsteel Strike and its Z-Move variant, Searing Sunraze Smash.
• Power Parasite: The most effective way for it to absorb light into itself appears to be via absorbing Solgaleo/Lunala, shifting its body around to accommodate its host, and leeching off the light they naturally (and constantly) generate. It also gains access to the host's typing, Secret Arts, and Z-Moves.
• Pulling Themselves Together: This appears to be what Necrozma's base form is; after losing the light that formed its body, the brain prism telekinetically used its disembodied prism armor to make a rudimentary body for itself.
• Purposely Overpowered: While its stats aren't as high as Solgaleo and Lunala (at least in its standard form), its use in Battle facilities and online play is still restricted.
• Puzzle Boss: Attempting to brute force Ultra Necrozma will likely get your entire team slaughtered due to its enormously boosted stats and diverse movepool. However, it is vulnerable to numerous tricks that make it easy to defeat, because a single Pokémon has limits to its power due to the game mechanics.^note Such vulnerabilities include a Zoroark in disguise as a Pokémon weak to Psychic, using Encore to lock it into a move with a type immunity/resistance, a Ditto, surviving a One-Hit Kill due to Affection, use of Perish Song and the F.E.A.R. tactic.
• Recurring Element:
  • Following Rayquaza, Giratina, Kyurem, and Zygarde, Necrozma is the "secret" third Legendary of a generation's primary duo, though Necrozma's relation is a lot less personal than either of those four. Just like them, it's also part Dragon-type, albeit only in its most powerful form.
  • Like Kyurem, Necrozma absorbs its two brethren to transform into a stronger alternate form with aspects of its partner. However, while Kyurem can fuse with its components due to all three once being a single dragon, there's no special relationship between Necrozma and the Cosmog line that allows the former to fuse with them beyond their mutual association with light.
  • A powerful Psychic-type Legendary Pokémon who has at least two Super Modes, a devastating Secret Art that works differently compared to other Special Attacks, an abnormally savage and cruel attitude induced through human interference, and a role as a primary villain in at least one form of Pokémon media. Are we talking about Necrozma, or Mewtwo?
  • Necrozma's face and the triangle in the foreheads of its Dusk Mane/Dawn Wings formes is actually its "brain prism", much like the crystal at the center of Deoxys' body. Both are primarily Psychic-type, have four different formes, and are powerful aliens; the extraterrestrial Deoxys and the extradimensional Necrozma. Their signature moves are also the two strongest Psychic-type moves (ignoring Z-Moves).
• Redemption Demotion: It goes without saying that Necrozma can be captured in Ultra Sun and Ultra Moon despite being the main villain. But if you were hoping for it to retain the stat-boosting aura it uses as Ultra Necrozma, too bad. You can replicate it using Roto Boost, but that takes a turn to use, and for multiplayer battles, forget it. You can recreate the Totem Boost somewhat in both singleplayer and multiplayer, however, by Baton Passing a boost from Ancient Power or other similar moves, as well as Z-Moves with such an effect.
• Sealed Badass in a Can: Its Sun dex entry says that it apparently has been dormant underground for ages after appearing in this world in ancient times. It's taken further in Ultra Sun and Ultra Moon, where Necrozma was instead sealed away in Megalo Tower in Ultra Megalopolis many years ago to stop its rampages. The tower reaches its limits by the time of the game's events, though, leading the Ultra Recon Squad to visit Alola to find a way to stop it before it breaks free.
• Secret Art:
  • Necrozma is the only Pokémon to have Prism Armor, an ability that lets it take 25% less damage from super-effective moves. Unlike its counterparts Solid Rock/Filter, it's unaffected by Mold Breaker and the like, and is also one of three Abilities (the others being Full Metal Body and Shadow Shield) that can't be ignored by Solgaleo/Lunala's signature moves, as well as Necrozma's Photon Geyser and all three respective Z-Move variants.
  • Ultra Necrozma, on the other hand, is the only Pokémon to have the ability Neuroforce, which increases the damage of super-effective moves by 25%.
  • It's the only Pokémon to learn Prismatic Laser, a Psychic-type move where it fires devastating lasers with its prisms. While it deals absolutely ludicrous damage, Necrozma needs to recharge after using the move.
  • Pokémon Ultra Sun and Ultra Moon adds in Photon Geyser, a Psychic attack that deals physical or special damage depending on which of Necrozma's offenses is currently the highest. Like Solgaleo/Lunala's signature moves, it also ignores the target's ability.
  • Its alternate formes attain Sunsteel Strike/Moongeist Beam after absorbing their respective user, and with Solgalium-Z and Lunalium-Z, they become the Z-Moves Searing Sunraze Smash and Menacing Moonraze Maelstrom, much more powerful versions of the original moves.
  • Ultra Necrozma can use its mandatory Ultranecrozium Z Z-Crystal to convert Photon Geyser into Light That Burns the Sky, an even more powerful version.
• Sequel Non-Entity: Although it isn't officially classed as a Mega Evolution, Ultra Necrozma was removed from Sword and Shield alongside them and Z-Moves. As of Generation IX, Ultra Necrozma hasn't appeared in the core series since its debut in Ultra Sun and Ultra Moon, even in games where Necrozma and its other two forms are usable.
• Shed Armor, Gain Speed: Dusk Mane and Dawn Wings Necrozma have comparatively better defenses than Ultra Necrozma, in addition to having the Prism Armor ability that reduces super-effective damage against them. Ultra Necrozma loses those few points of defenses to gain a noticeable boost in speed, and trades away the defensive Prism Armor ability for the offensive Neuroforce.
• Shout-Out: Ultra Necrozma's Shiny palette is the exact same bluish-silver color as the Blue-Eyes White Dragon, which is also light-elemental.
• Shown Their Work: Ultra Necrozma's body, bar some prismatic body pieces, is made of light. Light has no mass, which explains why Ultra Necrozma weighs exactly the same as base form Necrozma despite being significantly larger.
• Signature Roar: Like the Cosmog line and the Ultra Beasts, Necrozma's cry has a mechanical-sounding "hwoo" at the end, affirming its origin as a being from Ultra Space.
• Silicon-Based Life: Its body is made out of black crystals that act as prisms. Ultra Sun and Ultra Moon elaborate that said crystals are armor, and Necrozma's "true" form is a normal triangular prism with colored bits inside it (which forms the symbol on its Dusk Mane/Dawn Wings forms' heads, and can be seen when it transforms into Ultra Necrozma).
• Single Specimen Species: Unlike the Cosmog line and the Ultra Beasts, there's not much evidence to suggest that Necrozma isn't the only one of its kind. And really, can you imagine several ultra-powerful giant light dragons running around? Likewise, its original form was called "The Blinding One", further indicating there is and was only one.
• Situational Damage Attack: Both Photon Geyser and Light That Burns the Sky deal damage based on whether Necrozma's Attack or Special Attack is higher, taking the higher value and hitting the opponent's Defense/Special Defence respectively.
• Slow Laser: Necrozma's primary means of attack is absorbing light and firing it out as powerful lasers. The one move it learns that uses lasers, Prismatic Laser, depicts them as slower-than-light beams that rain down on the target after Necrozma fires them in several directions.
• SNK Boss: Your final battle with Ultra Necrozma. On top of its already incredible base stats and very high level, when the battle starts, its aura flares up and every one of its stats is buffed one stage. Not only that, two of its moves, Smart Strike and Dragon Pulse, aren't even moves it can learn without either a TM or a Move Tutor.
• Soul Power: Dawn Wings Necrozma is part Ghost type, and can use Lunala's signature move Moongeist Beam.
• Starfish Aliens: Necrozma hails from another world, and is a light-stealing prism whose body doesn't match any sort of existing animal (and whose true body is made out of pure light and prisms). Even in-universe, no-one knows whether or not Necrozma counts as an Ultra Beast (themselves very unearthly and bizarre).
• The Stars Are Going Out: In its current maddened state, Necrozma seeks to steal light from whatever world it visits, completely and permanently shrouding it in darkness as a result. As far as we know, it only succeeded in doing this to one world — Ultra Megalopolis. It was repelled from Alola in the distant past, and subsequently imprisoned by the people of Ultra Megalopolis to keep it from causing more damage.
• Status Buff: It can learn several stat-boosting moves, such as Iron Defense, Swords Dance, Calm Mind, Autotomize, Dragon Dance, Cosmic Power and Rock Polish, and has access to Stored Power to use those boosts to blast through its opponents. It also uses an aura that raises all its stats by one stage in the battle with Ultra Necrozma.
• Super Mode: Dusk Mane Necrozma and Dawn Wings Necrozma can both transform into the immensely powerful Ultra Necrozma if they hold its signature Z-Crystal, the Ultranecrozium Z.
• Super-Toughness: Its Ability in all its forms except Ultra Necrozma is Prism Armor, which reduces incoming super-effective damage by 25%. This, combined with its monotype (no double-weaknesses) and several defense-boosting and healing moves, gives Necrozma quite a bit of durability compared to Pokémon with the abilities Filter and Solid Rock, which have the same reduction effect — and unlike those, Prism Armor can't be negated by abilities and moves that ignore abilities.

T-Z

• Talking Animal: At Megalo Tower, Ultra Necrozma screams a coherent English word: "Liiight!"
• Technicolor Eyes: Its base form's "eyes" are made up of differently colored shapes on its prism core that, thanks to their placement and that of Necrozma's armor, resemble triangular eyes. Ultra Necrozma's eyes are more organic eyes, though they're also made up of differently colored shapes while lacking anything like pupils.
• There Is No Kill Like Overkill: With very high Attack and Special Attack, stats that exceed Arceus, a movepool with great coverage, and an Ability that makes super-effective moves hit even harder, Ultra Necrozma's more than capable of ripping holes in your team. And then it uses an aura to boost all its stats by one stage... Still, be glad it doesn't use its Z-Move, Light That Burns the Sky, which effectively throws a large sun-like nuke at the opponent.
• Thinking Up Portals: Like Solgaleo and Lunala, it can create Ultra Wormholes of its own volition, as seen when it ejects Lusamine and Guzma from Ultra Space. Like Solgaleo and Lunala, it can also use an Ultra Wormhole to travel to the Reverse World in the Ultra games, but it needs to be in one of its forms depending on the time of day (Dusk Mane at night, Dawn Wings in the day). In the Crown Tundra expansion of Sword and Shield, the Necrozma of that game's continuity opens up a Ultra Wormhole for a short time above a labyrinthine Max Lair, causing a small horde of Ultra Beasts to spill into the lair.
• Third Eye: Much like Solgaleo and Lunala, its Dusk Mane and Dawn Wings formes appear to have this. Said "eye" is actually Necrozma's brain prism, with the viewer looking at it from the topmost angle. It glows like said eye when using its host's Secret Art or its Z-Move variant.
• Time Abyss: Necrozma is either biologically immortal or extremely long-lived, since the Necrozma encountered in Ultra Sun and Ultra Moon's present is the same one that attacked Alola five hundred years previously, and who'd been flying across Ultra Space for long before that, even with its life-crippling injury.
• Tragic Monster: In a more-literal sense. Necrozma is a cruel and rage-filled Pokémon whose end goal of restoring itself has negative consequences for Nebby and the rest of Alola, but had it not been for the influence of greedy humans long ago, it wouldn't be in the state of broken, constant pain that drives it to such ends. And even worse, the player can never truly cure it; the best they can do is lessen its pain by having it absorb Nebby (a process that can rob the latter of all free will, though it's indicated Nebby is willing to do this to help), although simply being near the player character and their large collection of Z-Crystals also brings it comfort.
• Token Evil Teammate: "Evil" may or may not be too strong a word, but so far, no other Pokémon that can be caught and trained has Big Bad credit under their belts (barring spinoffs and adaptations).
• Took a Level in Badass: Necrozma isn't much on its own; it has high stats and an Ability that lessens its weaknesses, but it isn't as powerful as Solgaleo or Lunala. Once it absorbs either of them, though, it gains their respective offensive specialty at a higher level and gains increased respective defenses (though with less Speed), and it keeps Prism Armor to make it tougher to take down. And once it Ultra Bursts, Ultra Necrozma becomes one of the very few Pokémon that has higher overall stats than Arceus with equally proficient offensive stats, high Speed, and an Ability that makes super-effective moves even stronger.
• Top-Heavy Guy: Not that it makes much of a difference since Necrozma is always levitating, but in its base form, its legs are tiny compared to the rest of its body.
• Tortured Monster: Its idle animation shows it clutching itself in agony. Ultra Sun and Ultra Moon reveals this to be because it was mutilated long ago by the ancestors of the inhabitants of Ultra Megalopolis and it now exists in a constant state of agony and hunger, with a mean and vicious temprament to boot.
• Total Eclipse of the Plot: Necrozma and its formes seemingly embody an eclipse, and Ultra Sun/Ultra Moon implies that it covered Alola in darkness by (attempting to) steal its light, much like a solar or lunar eclipse would. This is even first told to you after such an eclipse briefly occurs at the beginning of the game!
• True Final Boss: In Sword and Shield, Dynamax Necrozma serves as this for the Crown Tundra DLC once the main story has been concluded by catching the other legendaries.
• Unperson: Ultra Sun and Ultra Moon's postgame reveals that Necrozma's attempt to drain light from the world was recorded, as Alola's first encounters with Cosmog, Lunala and Solgaleo were. However, the king didn't want the people of subsequent generations to live in fear of Necrozma returning, and had the book recording its attack burned. Somehow, some of the book survived, but even then it was hidden away, and thus for almost everyone the specifics of the event faded from memory over the generations, replaced with a vaguer account of how at one point, darkness covered the land but was repelled by light from people and Pokémon.
• Unwitting Instigator of Doom: As a byproduct of it opening Ultra Wormholes upon absorbing Nebby, it sends Ultra Beasts into Alola (as opposed to Lusamine in the originals). More crucially, long after its defeat, its Wormholes are how Team Rainbow Rocket enters Alola.
• Villain Decay: Necrozma is a major threat when it first shows up in Ultra Sun and Ultra Moon, absorbing Nebby and becoming considerably more powerful. After this, it becomes Ultra Necrozma, and proves to be one of the most dangerous and hardest boss battles in the franchise. Finally, you see it in Mount Lanakila... in its base form, and so weakened that it needs your Z-Ring's light to reawaken. Even when it fights you soon after, its movepool is much less intimidating, and it's (near) inexplicably just as easy to capture as the Caterpie and Pikipek just outside your house.
• Villain Forgot to Level Grind: Inverted; in Ultra Sun and Ultra Moon, Necrozma gains levels between each of your encounters with it, even during encounters that practically happen one after another where it would be implausible for it to find the time to level grind. First, it's level 50 when fought at the Altar of the Sunne/Moone. After you beat it, it retreats to Megalo Tower, where it becomes Ultra Necrozma and inexplicably jumps up a whole ten levels to level 60. And after you beat it again, Necrozma ejects itself to Mount Lanakila in a heavily injured state, where it's somehow five levels higher at level 65 despite it being in no shape to fight and train against other Pokémon.
• Walking Spoiler: Not only is Necrozma the Big Bad of Pokémon Ultra Sun and Ultra Moon, but the advertising wasn't kidding when it said Necrozma had many secrets. In fact, Ultra Necrozma's official gameplay trailer came out over one month after the games were officially released, with the Pokémon's existence never being formally acknowledged until then, just to give story-driven players a grace period to learn Necrozma's secret blind.
• Wave-Motion Gun: Prismatic Laser is even more lethal than Hyper Beam with perfect accuracy^note 160/100 power/accuracy to Hyper Beam's 150/90, but has the same drawback by having to recharge the next turn after a successful use. Meteor Beam also shows shades of this trope, although it takes 2 turns to use unless Necrozma is holding a Power Herb.
• Woobie, Destroyer of Worlds: The Blinding One was once known in its own world as a benevolent being who shared light with all and was deeply respected by the humans it lived among. That was until greedy humans sought to control its power long ago but only succeeded in hurting it and causing it to lose part of its body during the attempt, causing it to in turn lose its true form. In rage and pain, it seeks to steal light from others in order to survive, but its injury means that the light will always leak out and it can never fully heal or sustain itself. It is thus compelled constantly to feed, but this only causes it more pain and madness.
• Wound That Will Not Heal: Necrozma has one that prevents it from staying as Ultra Necrozma for long, said to be where a part of its body was broken off. Where said wound is isn't exactly stated, but it's presumably the end of its tail, where it's a stark white in contrast to the rest of its black body.
• You Can't Thwart Stage One: Given its presence on the front cover, Necrozma successfully manages to absorb Nebby and achieve its respective alternate forme. Likewise, it starts stealing Alola's light and successfully regains its original state.
• You Monster!: To cement its role as the Big Bad of Ultra Sun and Ultra Moon, previous baddie Lusamine flat-out calls it a monster.
• Your Size May Vary: Despite base Necrozma's torso being Ultra Necrozma's head, it very visibly changes size in that form, as it's much smaller than its chest (base Necrozma's tail).
