Required Secondary Powers in Fan Works.
Crossovers
- In Adopted Displaced, Apple Bloom develops a secondary power that keeps her Green Thumb power (which causes plants to sprout wherever she walks, even bringing dead wood back to life) under control.
- All For Luz: Whenever Luz gets severely injured a fight and activates her "Super Regeneration" Quirk, she also activates her "Pain Nullification" Quirk, as well. This is so that she doesn't succumb to the crippling pain as her body heals and she can keep on fighting.
- In Amazing Fantasy, Izuku develops Super-Strength, Super-Toughness, and greatly increased flexibility as part of his spider-based Combo Platter Powers. This is good news, as web-swinging would rip his arms out of their sockets and his constant acrobatics would have broken his spine if he tried performing them before the spider bite. Peter is aware of this trope and tests the limits of Izuku's powers first before moving on to web-swinging. He also has Izuku squeeze stress balls constantly until he can avoid popping them so he doesn't break things he doesn't want to.
- In Blood and Fire, the Citadel races know the science behind Covenant plasma weapons, but they lack the material science and power generation knowledge to make the things work in a practical, combat-useful package rather than in the laboratory.
- In The Bridge:
- When a cloud of dirt gets in Xenilla's airways, he notes that it doesn't really bother him since he can travel through outer space unaided.
- Destroyah is immune to her Micro-Oxygen. Her pony form, however, is not, at least until Discord grants her immunity.
- Raiga is adapted to living in the deep ocean, so she can see in the dark.
- Megalon can sense vibrations so that he can navigate when burrowing underground. This also means he can navigate in the dark.
- Since the Sirens are adapted to living in the ocean, they are not easily bothered by cold, even in their human forms. On the flip side, hot and sunny weather can make them feel light-headed and lethargic.
- Since Princess Celestia has The Power of the Sun, she is almost completely immune to fire and heat.
- All of the Guardian Beasts are immune to their own elemental powers. In fact, it actually makes them stronger.
- Irys is a Gyaos, a flying species, so her body is partially protected from the effects of extreme speed and maneuvering like impacts and getting dizzy. Since she can't stand light and can release a black mist that blocks light, she can navigate in the dark.
- In Changing of the Guard
, part of the There Was Once an Avenger From Krypton series, Ben's alien transformations come with the memories of the original DNA holder, which he experiences every time he transforms. As he points out, he'd need to basically relearn everything such as walking and talking just to use the new body the Omnitrix grants him if it didn't do this. - Subverted in Cinders and Ashes: the Chronicles of Kamen Rider Dante for the Kamen Riders themselves, as despite having protection from directly controlling their elements, they aren't guaranteed to be safe from them. This is made worse by the fact that these powers were translated into the real world, and as such, these powers are subject to real-world logic.
- The Volcano Belt is noted to protect Dante from the flames it produces, but not its heat, essentially meaning that Dante could potentially be cooked within his armor if he's not careful with using his powers. Made even more so if the belt draws in too many flames, which leads to Hoshi getting burn scars from one such incident.
- The Avalanche Belt parallels Dante in that it protects Verge from frostbite but not hypothermia.
- The Plague Belt, noted in a post on SpaceBattles.com, works similar to the other belts in that it protects Docro from poisonous materials, it does absorb the poison into the body. This is made worse if they happen to have a disease, as the poisons will either kill the disease and lead to a depower or, more commonly, make the disease worse and kill the person in the process.
- Echoes of Yesterday:
- Kara explains to the Heberts that she has some sort of "body aura", which is because she can lift massive objects without them collapsing."Actually, getting there shouldn't be an issue. I'm not as fast as I could be, but I could easily carry Taylor to the mountains; it would only take a few minutes for me to run there. And there's no wild animal that could possibly hurt either of us while I'm there."
Taylor paused and gawked at me, "I'm sorry. Can you run that by me again?"
"Is that safe?" Danny added.
I nodded, "Perfectly. I… well it's complicated. But if I'm touching something, it becomes more durable; it's why I'm able to lift things that would otherwise collapse under their own weight if I did, and why the ground doesn't give way under my feet when I do. As long as Taylor holds on tight, she won't have to worry about a thing." - Later in that chapter Taylor asks how Kara can see anything while she runs at super-speed. Kara's answer? Super Reflexes.Taylor: H-holy shit! How do you see or do anything when you're moving that fast?
Kara: Enhanced reflexes.
- Kara explains to the Heberts that she has some sort of "body aura", which is because she can lift massive objects without them collapsing.
- End of Hatred, Beginning of Hope:
- Rainbow Dash tells Pinkie/Fili-Second that because she has Super-Speed, her metabolism burns through calories much more quickly, and thus she needs to consume more food.
- Also, Pinkie possesses a force field that protects her from the effects of friction due to her connection to the Speed Force. Also, while her body is protected, her clothes are not (unless they're skintight) and tend to catch fire whenever she runs.
- As Twilight Sparkle notes, Rarity/Radiance must have a firm understanding of whatever she wishes to make an energy construct of.
- Equestria Girls: Friendship Souls:
- Arrancars, Soul Reapers, and Quincies may have superhuman strength and durability, but they still weigh the same as ordinary people, meaning regular people can knock them down if they don't brace themselves.
- Quincies have to activate Blut Vene before using Hirenkyaku so that the excessive G-Forces don't kill them.
- Similarly to the Quincy example above, Applejack notes during her fight with Troubleshoes that her Fullbring forms a protective aura around her body, allowing her to jet around at breakneck speeds without hurting herself. She suspects that Rainbow's does the same thing, as do the others, if to a lesser degree.
- Twilight's Schrift The Variable is incredibly versatile, but its main drawback is that in order to make it work at its full potential she needs to know exactly what the thing she's trying to change the variables of is, or at the very least make educated guesses as to its nature, plus she needs the mathematical and scientific knowledge to know what variables she wants to change and by how much (which makes her incredible intellect quite useful).
- Sunset is normally immune to her own Zanpaktou flames, but her black flames, drawing from her wrath, can even injure her.
- Fenice is fully immune to the molten rock her Magma Man powers generate, and has full control of its motion besides, allowing her to "surf" a wave of magma.
- Celestia is similarly immune to the incredible heat of her Bankai.
- The Games We Play:
- Gamer's Body, by providing Critical Existence Failure and turning all harm into quantifiable HP loss, enables Jaune to avoid the wear and tear that would otherwise come from the Cast from Hit Points skills.
- Gamer's Mind protects Jaune from getting overwhelmed by all the input he gets from his Super-Senses. Reinforced when Gou uses Clairvoyance in "Believing" and finds the added input 'disorienting and dangerous to use in a fight'.
- In "Faces" Jaune explains in detail why trying to use illusions to make one appear bigger or smaller is very difficult - there are so many little details one has to get right. Applying illusions on others is also difficult, even with Aura to massage some of the fiddly bits.
- Acceleration is Time Mastery applied only to Jaune, but not to his Elementals or allies, which means he can't use them as effectively while he's sped up. Also, spending all that time while dilated means he's physically older than the calendar would suggest.
- Tenne's ability to guide projectiles using his eyesight is disrupted when he blinks, and training and experience only go so far in trying to counteract this natural tendency. When Conquest infects him, he gains many more eyes, and unblinking Grimm ones at that, making him much more effective.
- In "Homecoming", we see how many things Jaune has to do in order to be stealthy. It's not enough to use Delusory to bend light and hide himself visually - he needs to control air to prevent sound leaking or unwanted wind motion, control heat to prevent the air from heating from friction as he moves at Super-Speed, and harden the ground to prevent it cracking under his Super Strong footfalls.
- Some of the Skills Jaune learns explicitly don't provide their user with any protection should they backfire on him.
- In "Examination" Jaune notes that Aura doesn't increase mass or provide additional anchoring. In high-level combat, even if an attack doesn't deal enough damage to noticeably deplete Aura reserves, it's still possible to have someone Blown Across the Room.
- Harbinger mentions this in regards to Shepard's Psychic Powers that allow him to move at Super-Speed. His fists move extremely fast when he strikes someone in close quarters, hard enough to crumple armor and throw people across the room, but his arms also move so fast and with so much force that they'd break on impact. His armor and omnitool generate a dual-layer mass effect field (pun questionably intended), with the outer layer being a hardened kinetic barrier while the inner layer being a "cushion" that behaves like ballistic gel, absorbing the reaction to his punches.
- iFight Crime With Victorious
- Carly has the ability to read minds and doesn't suffer from the flux of thoughts she's bound to be hearing every day like most telepaths do.
- Sam has superhuman strength, and while not Nigh-Invulnerable, her stamina and endurance are increased to the point where Carly, while borrowing her power, was able to do two hundred push-ups in one sitting. Her lack of invulnerability comes out when she gets hospitalized for a stab wound.
- Freddie is able to learn and adapt from just about everything he reads or observes to the point where he self-heals just from reading a chapter on how blood coagulates and his bones reinforce themselves after being broken by Sam, and his body doesn't take any cues from the internet, or average students, or insects.
- Infinity Train: Seeker of Crocus: Vaillant is a Silver Werewolf who has the power of illusion. When someone tries to brainwash him in the Model Diorama Car, he goes on a tangent in stating that a master of illusion must also have strong mental defenses, thus he's Immune to Mind Control as well.
- Memories of Iron:
- Quite a bit of the fic is dedicated to discussing the need for Taylor to gather resources and develop appropriate tools and subsystems in order to recreate the technology Tony had.
- Defied with the mass production Iron Legionnaire suits. One of the key selling points Taylor offers to the US Army is the fact that they don't need special training to maintain or operate, which cannot be said for most Tinkertech. This is explicitly demonstrated when she rejects the top pilots the military intended as testers in favour of ordinary line troopers, who still manage to quickly learn the ropes anyway, then offers a suit to the motor pool to fiddle with. No matter what abuse it gets put through, it still remains within the ability of non-superpowered mechanics to work with.
- "The Not-So-Average Girl" features Peter Petrelli (Heroes) essentially acquiring the necessary extra powers to avoid his canon issues when he meets Kim Pierce (a variation of Kim Possible) who possesses the power of an enhanced survival instinct. Kim’s power immediately allows her to know how to survive in any dangerous situation, ranging from making her a brilliant student (making it easy for her to learn information that will help her survive) to accelerating her reflexes so that she can escape dangerous situations. By copying Kim’s power, Peter thus gains a greater instinctive knowledge of how to use the other powers he has absorbed, helping him avoid some of the Idiot Ball moments he faced in the show.
- Not the intended use (Zantetsuken Reverse):
- Soma cannot be harmed by the souls he possesses or from the abilities they have, which is very useful some of them - such as the Persephone's soul Hell Gate - are extremely dangerous. In addition, some souls come with this trope on their own. For example, the Ghoul soul, which makes rotten food edible, also makes it taste fresh.
- Julius says that one of the vampires's less-known abilities is immunity to bloodborne diseases. Makes sense when blood is their food source.
- The Suou family, who can all control fire, are immune to burning or feeling heat.
- Eikichi, who can control water, is immune to drowning.
- Chapter 22 notes that the Killer Clown soul's ability to manipulate the order of a deck of cards, also means knowing what cards a deck has.
- The Secret Return of Alex Mack: Played straight in several cases, but frequently averted.
- Sato Yuki gains cold powers, except they work by turning her into a massive heatsink. She is in serious danger of freezing to death on first gaining her powers and must remain in well-heated areas.
- Pyrokinetics who gained their powers via GC-161 have no immunity to their own heat by default, and their power is highly painful. Victor Cready actively hates his power, and Jack O'Neill dubs him "Flamey the Wonder Ouchy". Interestingly, after his powers are stabilized he ends up dating Sato.
- Pyre, on the other hand, was born with powers rather than getting them from GC-161 and is extremely heat-resistant.
- Grover Dunn is invisible, but only to normal light. He still shows up in infrared, which is also how he sees. He bypasses the clothes issue by using the invisibility formula on sheep and then making clothes out of the wool. He even uses the meat as an invisible snack.
- The sequel establishes that all versions of Alex with lightning powers are immune to being blinded by their own lightning strikes.
- Sleeping with the Girls vol II:
- Washuu restores Luna's ability to turn into human form. Later we learn she also retained cat's muscle density, which makes her really strong and agile but also uses proportionally more energy. So she either has to eat a lot in human form or stay most of the time as a cat to save energy.
- The protagonist receives a strength multiplying bodysuit, and learns the hard way it lacks any kind of reinforcement (he forgot to read the manual, then punched a wooden pillar breaking his wrist). Fortunately he still has medical nanites, but those too use a lot of fuel while healing major injuries. He still hasn't been able to read the manual.
- Snuggles the Symbiote: Ashley has superhuman hormone production and superhuman chemical resistance to keep her from overdosing on her own hormones. This trope is played with, however, in that her two powers don't line up perfectly and the resulting hormonal imbalance leaves her physically weak, severely compromises her immune system, and her secondary powers come with a side of Immunity Disability.
- In the Stardust sequel Mente Materia Matt's Super-Reflexes don't come with a boost to his physical speed, meaning he can see things happen but can't physically respond to them in time. He can activate his magic though.
- The Star Trek and Babylon 5 fanfic "Task Force 43" lampshades this viciously when the Vree attempt to blackmail the Federation into accepting them into the Federation under threat of proliferating warp technology to the local races. To counter the blackmail, the Federation ambassador hands out data crystals containing basic information about warp technology (Roughly equivalent to what Cochraine had during his first warp flight). What they do not give, however, is Federation anti-matter energy production technology, which is the only way to produce enough power to sustain a warp field for a ship larger than a small fighter.
- In Thieves Can Be Heroes! Ann Takamaki has the Quirk "Razor Teeth", which makes her teeth inhumanly strong with a visible cutting edge, letting her bite through even metal with enough effort. She mentioned once that her tongue and the inside of her mouth are super tough as well, so she can talk and eat food without the risk of cutting herself on her teeth.
- Lampshaded in Ultra Beast of the Bay. Taylor recognizes that the faster something moves, the tougher it has to be in order to not be destroyed by friction or inertia. Since she's easily supersonic, she might well be bulletproof as well. As Taylor's musing as to whether she's willing to test this, a bullet shatters on her body because she forgets that she's actively being shot at.
- In The Universiad, OSR augmentations are so powerful that Power Limiters are needed, with many careless operatives destroying themselves from careless use.
- In An Anthem for Sheltered Bays, Eren, being a mermaid, has eyes light-sensitive enough to see in the dark and greater upper body strength to make up for a fish lower half.
- A Certain Droll Hivemind: Averted with Aino Sumiko. She is a Level 1 with the Meltdowner power, the ability to create microwave radiation; the Level 5 with the same power uses it as a Wave-Motion Gun. But she completely lacks any protection against her own power, meaning she basically just has the power to give herself radiation burns. Her classmates call her "the Suicider."Aino Sumiko: Well, I need to go irradiate myself and get more burns on my hands. What fun. You two enjoy having powers which aren't super-fun in the way they hurt you when you practice.
Misaka Yui: I do not think that would be fun, Misaka says, the confusion obvious in her voice. I think that would be very painful. Much like electricity burns, she adds, speaking from painful experience.
- In The Danny Phantom Superhero Project, Danny got his powers from Jazz, who then started selling temporary powers to would-be villains to fund her research. When Danny discovered this, she gave herself Super-Speed in order to get away, but when she tried to spin around on her left leg, all the cartilage, tendons, and ligaments from her knee down disintegrated from the sudden g-forces. Word of God says that he was always confused by how speedsters like the Flash could corner like that.
- The Shazam! fanfiction Here There Be Monsters establishes that the Marvel Family's magically enhanced strength and endurance allow them to move their impossibly increased mass when they surpass the speed of light.Their speed exceeded that of light. Only their great power could move the mass their bodies had accumulated now. They did it without seeming effort.
- Risk It All:
- Discussed. While mulling over the weirdness of his gamer powers, Ren notes that abilities like Thou Shalt Not Kill aren't too weird to wrap his head around, given that Superman must clearly have some kind of tactile telekinesis to avoid ripping every plane he catches in half.
- Subverted with Ren's Flash Step. While it gives him a burst of speed that lets him cross short distances nigh-instantly, he doesn't have the reaction speed to respond during this time and has to wait until he slows down to properly throw a punch. His inability to turn means that he can't use this if someone is in the way, lest he crash into them.
- In the Superman fanfic Superman of 2499: The Great Confrontation, Katherine's brother Zor-El got crippled because he's super-strong but lacks the necessary invulnerability to endure his own strength.
- The Frozen fic "Feel, Don't Conceal" focuses on Elsa and Anna becoming lovers, with Elsa immediately shocked when she realises that Anna has just spent the night with her and yet, despite Elsa's powers freezing most of the room, Anna herself isn't cold at all despite basically spending hours naked in an icebox. Anna speculates that Elsa accepting her feelings for Anna involved her powers "claiming" Anna in some way that means she is basically immune to the cold; she is aware when she's holding something cold, but she doesn't feel it to a dangerous extent.
- In Daily Chaldea, Ritsuka Fujimaru's Sex Shifter magecraft has a secondary power to change their clothes with their gender. The "Harem Protagonist" skill they received from Void Shiki also has a secondary power to reduce jealousy among the Heroic Spirits it attracts, so Fujimaru's in no danger of being murdered by Yandere Servants.
- Nerve Damage: Nero wields the Flaming Sword Aestus Estus. It is mentioned that holding the sword makes her immune to fire and lava.
- In The Awakening of a Magus, Harry's body changes into a not-quite-human physiologically to allow for channeling the enormous amounts of power he has. Unfortunately, the change is gradual, and it requires a long time before his full potential is usable.
- Gankona, Unnachgiebig, Unità: Italy has superspeed, and can reach max speed in an instant. This means he has to be able to accelerate/decelerate in a flash. He also doesn't die instantly due to sudden deceleration.
- In Those Lacking Spines, Vexen states that one of the traits of being a "Part-Disney" character is an immunity to Disney Earworms, which the villains were trying to torture him with. The Cake Song worked just fine.
- A Fantastic Four 2099 fanfic series occasionally explored the limitations of the characters' abilities in this way:
- Johnny Storm (or rather, his clone — all of the Fantastic Four of 2099 are clones of the originals) is at one point exposed to the Negative Zone's poisoned atmosphere through a leak in a labor frame suit he was wearing/driving. He ended up briefly coughing from it, but otherwise he sustained no long-term effects from it. When questioned about this later, he pointed out that as The Human Torch he tended to be surrounded by plasma flame, meaning that the very air he inhaled was superheated plasma. His lungs would have been scorched without the Required Secondary Power of enhanced lungs that could very efficiently filter out what he breathed. As a result, breathing toxic Negative Zone air was relatively a piece of cake, and he was shown doing so without a gas mask on at least one occasion.
- On the other end of the spectrum, the clone of Ben Grimm has the same rocklike epidermal layer as his predecessor — which he at one point described as "a full-body callus strong enough to withstand being hit by a missile." Unfortunately, his thick hide was still pierced on a few occasions, but the injuries were slow to heal, leaving deep craters and sensitive scar tissue in their wake.
- In Minsinoo's Climb The Wind, Logan mentions that he has increased protein needs as a result of his healing factor. Also, he's not good at dealing with chronic pain, because he's used to things healing almost instantly.
- Mass Effect: Human Revolution:
- Similar to Halo's MJOLNIR, the 108 suit is too powerful for an unaugmented user to safely use.
- In chapter 34 Smuggler points out that while he could easily recreate the electronics and materials needed for the airbursting explosive rounds, the software and targetting computer needed to make them work right isn't so straightforward, not something he can create in the short time available.
- Alexandre's nanoaug armour doesn't completely nullify kinetic transfer, meaning that Ursus can stun him with a strong enough punch to the head.
- Forever He-Man deconstructs this. He-Man's extraordinary strength comes in part from high levels of adrenaline, which wasn't ordinarily a problem because it left when He-Man turned back into Adam. With the sword gone, not only are his adrenaline levels off-the-charts and affecting his stress levels and strength, when it fades He-Man gets tremors that take a long time to subside.
- Crimson and Emerald: Due to having bird-based quirks, both Hawks and his mother Kiyome have the superior eyesight of real-life birds of prey. Which allows them to see far away in flight and catch the subtle nuances of body language.
- What's in a Hoard?: Izuku's entire family has some resistance to the Breath Weapon of other dragons and complete immunity to their own. Since Izuku's Breath Weapon is poison, he's immune to all known drugs and medicines because his body treats them as poison. Fortunately, his blood is also poison so Izuku's also immune to disease as foreign microbes simply can't survive in his bloodstream.
My Little Pony: Friendship Is Magic
- Fall of Starfleet, Rebirth of Friendship:
- As is a common Required Secondary Power with many speedsters, Rainbow Dash possesses a much more efficient metabolism to get the energy needed for her Super-Speed. This also means that she cannot get drunk (or at least has a very difficult time trying to get drunk).
- Ragamuffin has dead nerve endings which is why she cannot feel pain from her injuries. This also means that she cannot feel when parts of her body have been rendered useless when they have sustained too much damage. She does not notice that her Achilles tendons have been sliced until she discovers that she cannot walk.
- As explained by Thorax, Changelings change everything in their bodies when they transform, including: molecular density, vitals, blood type, bone structure, organs, and even DNA. The only things they cannot replicate are memories and magical aura. This explains how Thorax was able to mimic the abilities of animals and not just their appearances, such as using a gorilla's brute strength, in his Beast Boy disguise.
- Foalsitting Follies: Rainbow is granted Super-Speed by the Druid's Grove, and she exploits this trope to survive doing tricks that tend to shatter spines (though she still gets a sore back for several days afterwards).
- In the Lunaverse, Trixie's invisibility doesn't work against Octavia because not only can the latter hear the sounds the former is still making, she can also hear the inappropriate absence from a silencing spell. By the time At the Grand Galloping Gala comes by, Trixie has come up with a way around the problem.
- In No Nose Knows, Celestia's sun-raising power is shared with Luna, but only Celestia has the fire affinity needed to raise it safely. When Luna has to raise it in Chapter 28, due to Celestia being ill:“Meh,” Celestia verbalized how she felt afterward. “Is it time to raise the sun?”
“I think so, but Luna just checked in on us from the balcony so I think she’s raising it today.”
“She is?” Celestia asked, and she groaned when Bean nodded. “Ugh. She better not complain about it then.”
“About what? The hives?”
“No so much that. She—”
“HOT! HOT! HOT!”
“That—” Celestia said with a long-suffering sigh “—is what I meant.”
Bean looked on in amused horror as Luna, from within a magical shield, pranced into the room and blew out the small flame that had been burning on one of her wingtips. There was smoke rising from her back and from a few patches of singed hair on her sides, and it appeared that a few of her feathers had been turned to charcoal.
“You are hereby prohibited from ever getting sick again,” Luna announced, as she checked her other wing for any open flames. “And are you completely sure there is no way to turn down the temperature on that thing?”
- A fairly common idea in Sasuke- or Kakashi-bashing fanfics is to point out that while Kakashi used the Sharingan to copy the taijutsu Lee used against Gaara so Sasuke could use it in his fight against Gaara, Sasuke has not had the years of physical conditioning that Lee has to back it up, thus making it less effective (while in canon it worked rather well besides apparently tearing his leg muscles). Also common is Sasuke trying to copy the Shadow Clone technique without realizing he doesn't have the vast chakra reserves that Naruto needs to perform it.
- In Sugar Plums it's noted that to do nearly half the things they can do in canon and survive the things they survive, ninja have to be incredibly strong and incredibly durable as well as able to heal almost perfectly without major scarring from the wounds they suffer. It's said that shinobi have active and passive chakra, with the former being used for jutsu and the latter increasing speed, stamina, durability and allowing you to heal. When you run out of active chakra you can draw from your passive chakra but at great risk to yourself because the more you do so, the weaker physically you become, this is a point in-story because Ume, the main character, has such low natural chakra reserves that she has to do this in prolonged confrontation; under normal training circumstances she would have never even been taught to be a shinobi, or if she had would never have been allowed in a direct combat role. She usually compensates by keeping her battles as short as possible, but she gets her share of injuries, especially because she relies heavily on super speed in battle - one of the closest brushes with death comes from her hitting the ground too hard too fast while trying to escape from someone.
- Convergent Devil: Devil Fruits have a secondary effect of keeping their users from developing body dysphoria, though how it manifests varies. Alvida's Slip-Slip Fruit causes her to believe she was always an Amazonian Beauty rather than realize she now weighs about a tenth as much as she did mere minutes ago.
- This Bites!: Carue and the other members of the Supersonic Squad can, as the name suggests, run at extreme speeds. And much like a certain other speedster, they can automatically adjust their perception of time to match so they don't crash into things. When Carue accelerates, the world slows to a crawl.
- In Mergers several Pokemon abilities grant these to the people they merge with, like breathing water if you're part water Pokemon or being able to communicate with Pokemon in general.
- As well as the usual troubles with Pokemon, Pokéumans has a few of its own due to some characters having extra abilities beyond the usual. For example, John Dason's Sizeshifting requires a way to overcome the Law of Conservation of Mass.
- Cibus Esculentus Madoka Magica features a variation of this: Kyubey turns anyone who makes a contract with him morbidly obese, in order to make more wholesome meals out of them for Esurientes. While obesity itself isn't an actual power, their sudden weight gain also includes their muscle mass, in order to keep them at least somewhat functional for battle. Mami demonstrates actual superhuman strength by bending a piece of metal debris from an Esuriens attack, if just slightly.
- At the very end of With Strings Attached, we find out that the cloned bodies that the four are inhabiting had been supplied with complete immunity to disease to prevent them all coming down with dysentery two days after arriving in Focan, which was quite filthy.
- Also, Jeft talks to himself about all the stuff he had to build into Paul to get him to work properly:
~Now, I gotta say, I did a darn good job on him. Probably a good thing I didn't tell Shag and Varx that he only had about a forty percent chance of remaining stable after he came back together, with all the weird scalar/planar energy fields I had to design into him. They just don't have any idea what you have to go through to get a human-sized frame to be able to wield that kind of strength and still walk without creating giant holes or move his arm without blowing down everything in its direction. I still couldn't get it perfect, so he's always gonna make some chaos if he's not careful, but jeez, I was brilliant, converting most of that kinetic energy right back into raw Field energy before it even got past his skin.~
- Coeur Al'Aran:
- From Beyond: A Huntsman's Semblance alters their body (and sometimes mind) in ways to allow their power to work. If her body wasn't adapted for it, Ruby's Super-Speed would liquefy her internal organs, rupture her eardrums, and shatter her bones. It's theorized the reason Jaune's ghost has attached to Blake is because her Semblance has left her capable of dispersing and controlling her Aura outside her body, which Jaune uses to move any non-living body he possesses.
- Relic of the Future: A side-effect of Raven's teleportation Semblance is that she has a limited degree of precognition towards those she's bonded to: she immediately senses if they're in any life-threatening danger wherever they are; she can sense if one of them is near her; and she can otherwise tell where they are, what they're doing, and map their surroundings just by mentally reaching out. The latter trait enables Raven to avoid opening her portal into a wall, through another person or object, or on the outside of a moving vehicle when she teleports to their location.
- From Beyond
- I Rewrote RWBY Volume 8: Emerald's hallucination-creating, psionic-based Semblance causes her to sense the feelings and thoughts of whoever she's about to use it on as a side-effect. This secondary power proves to be quite useful.
- Discussed in the seventh episode of Sailor Moon: Legends of Lightstorm. Sailor Mercury tells Sailor Mars that her rocket-propelled speed is not a viable combat option because she's not a speedster, and therefore doesn't have any of the secondary powers required to use super-speed in close quarters (because of this, Mars always fights inertia and g-forces when running at high speeds, and therefore is forced to make very wide turns).
- Bait and Switch (STO) sometimes takes the required secondary technologies for space travel to the logical conclusion of weaponizing them. A recurring tactic is starship commanders (Captain Kanril Eleya in the original Bait and Switch, Romulan Praetor Velal in Peace Forged in Fire) using the navigational deflector that prevents the ship from being damaged by hitting interstellar particles at warp speeds at sublight speeds as a battering ram against smaller vessels.
- In Secrets of the Emeralds, much like in some early Western media, Sonic does not inherently resist friction and needs to wear special shoes in order to run at high speeds without being harmed by the resulting friction. When Robotnik captures and tortures him, he exploits the lack of this by forcing Sonic to run at top speed without his friction-resistant shoes on even as his feet catch on fire, leaving him far too injured to escape without help.
- In Shatterheart while R!Syaoran can replicate his clone's fighting style and abilities by learning through their shared eye, R!Syaoran has a slower reaction and doesn't fight as well because he didn't actually learn it himself.
- The Misfits (Warhammer 40,000) takes some time out to expound on the pitfalls of being an Intangible Man. Big Bad Aspiring Champion Phelonas, being a Chaos Space Marine, which is to say a genetically enhanced, demonically empowered Super-Soldier in Powered Armor, has a pretty cavalier attitude toward using a magic spell that temporarily removes not only his ability to breathe but also to feel air pressure of any kind whatsoever. So cavalier, in fact, that it doesn't even cross his mind what might happen when he tries to use it on a normal person...
- Atonement
- Tether's body is toughened to be resistant to recoil and whiplash, and extends this protection to whoever she's using her powers on, so as to avoid getting seriously injured whenever she pulls or pushes with her powers particularly hard.
- Sundancer's power allows her to create a miniature sun, so naturally she's immune to fire.
- Hindsight: Taylor's primary power is to get a glimpse of what will happen in the next several seconds if she continues her current course, at the cost of escalating headaches as she continues to activate it. However, to make this usable, her power also gives her perfect crystal-clear recall of what happened during that glimpse — and that recall is permanent, without causing any further headaches. So if, for example, she uses her power to study her class notes, then she now has a perfect memory of them, making tests easy.
- In Weaver Nine, the Society has a cape called Heavenly Fist whose power is the Megaton Punch. Unfortunately, while it does send targets airborne intact, it doesn't cushion the touchdown or slow the descent phase. As a result, anyone without Super-Toughness gets turned into a bloodstain on arrival.
- Wyvern: Taylor has a few of these in order to make her draconic form work properly:
- As she doesn't get flight powers like most of New Wave does (which fall into the Superman-style of flight, AKA just willing yourself through the air, supported by no visible means), she's more aware of how the air flows over her wings and is thus more maneuverable in the air.
- When in dragon mode, she's much more resistant to fire, helping prevent her from getting hurt by her own flames, but other heat sources don't bother her as much when she's a wyvern. Case in point, she finally relaxes enough to change back to Taylor under a hot shower... then shrieks in pain as she gets burned by how hot the water is.
