History ThatOneLevel / SuperSmashBrosUltimate

* '''Dry Bowser''' can be downright brutal to defeat properly. It isn't bad enough that the Battlefield form of Reset Bomb Forest is completely covered in lava and thus forces you to waste two Support Spirit slots, oh no. This fight also gives (Dry) Bowser the ability to receive curry effects at random points as well as gain a defense boost through the time it's effective, forcing you choose between whether you want lava immunity or a Franklin Badge since you can't have both together, as both abilities require two slots, (although Mega Diancie can fix this since it's a primary spirit that gives you the Franklin Badge). And worse yet, Bowser is no joke to fight against either, feeling downright merciless to you even before his first curry effect comes into play. All that can be said now is that you'd better have powerful spirits ready by the time you go facing off against him, because defeating him without one of the best is next to impossible. Oh, and did we also mention that '''this''' is the spirit that is [[BeefGate guarding Daisy's fighter battle in World Of Light?]] Yeah, good luck if you want to play as the princess of Sarasaland in that game mode.

* '''Dr. Wily''' is the optional spirit battle of the Base, and boy ''howdy'', is he extremely tough. The fight is a stamina battle on the Omega form of Dr. Wily's Castle against eight Metal Mega Men, who will relentlessly pursue you with deadly ranged attacks, with a combined total of a monstrous 800 HP. Wily himself isn't too tough due to him just being a single Dr. Mario with less HP than any of the Mega Man fighters on their own, but the battle to get to him is extremely difficult. Make sure you go in with a Franklin Badge, because otherwise you're going to have a bad time.

* '''Giga Mac'''. He has the tied most power in the entire game, that being 13,900. It puts you into the Boxing Ring with a giant Little Mac to represent Giga Mac himself, and he has super armor making him extremely difficult to get flying. His attack speed is also wicked too, draining your HP in a flash. To add insult to injury, his Final Smash gauge charges quickly. The stage's lack of BottomlessPits mitigates Mac's notorious weakness in the air and makes conventional [=KOs=] without wearing down his HP difficult. Any spirit that heals you every five seconds is a must-have, but it cannot go higher than the starting amount. Good luck trying to beat him because the title screen theme from the Wii ''Punch-Out!!'' game will be stuck in your head for a while. To quote Nathaniel Bandy, [[https://youtube.com/watch?v=EDmGMr00Fs8 "I was purely shocked with his destruction and left with a complete loss of words."]] And if you ever beat this one without any spirits on you, you're either lying or just cheesed him with the stage's set-up.

* '''Azura''' is a royal pain to deal with, being an extremely tough fight despite the simplicity of the conditions. Being a Legend Spirit, she has a very high 13500 power level, which in itself spells trouble. You're tasked with defeating a female Corrin with increased attack power on the Fountain of Dreams. The biggest problem, however, lies in how Azura's [[ExtraTurn singing powers]] are represented: Corrin gets Sudden [[LimitBreak Final Smashes]], which is deadly on its own, but the kicker is that she can use it ''twice in a row''. The starting hit of the attack is also AntiAir, creating pillars of light that can catch you while you're trying to approach her. The Corrin AI also happens to be quite smart and aggressive, and will wait for the perfect opportunity to snag you with her Final Smash for both easy damage and a potential KO, which she almost assuredly will considering how she has the capability to try it multiple times. Not helping is the fact that she [[BeefGate beef gates]] Corrin's fighter battle. Your choices are simple - deal with the [[LimitBreak Final Smash]] Hell or forget about getting Corrin in the World of Light.

* The first spirit you're introduced to in Joker's Spirit Board is of '''Morgana''' in Mementos, and this one can be quite tricky to pull off. It probably doesn't help that it has the highest point value of all ''Ace'' level spirits at an unusually high 11,500! For this one, you need to defeat a smaller than usual Pikachu with a Killing Blade included before not only occasional gusts of wind show up (meaning a spirit with strong-wind immunity is a must have), but a giant Incineroar with an Ore Club appears. While you only need to focus on Pikachu, the Incineroar's power and Ore Club will make it tough for you to focus solely on knocking Pikachu out. Plus, if you're not careful, the Incineroar can knock you out instead with one fell swoop through either the Ore Club or its Side-B attack.

* '''Riku''', as befitting his ThatOneBoss status in the original game, is sure to drive you up the wall. Facing off against a Corrin with enhanced move speed, they also start off with a black hole, easily trapping you in place at the start of the fight to be wailed on, and as it's a stamina match, not being able to be launched is small comfort. And he WILL abuse that move speed buff to go at you from every angle, constantly poking at you from just out of your reach, using hit and run tactics to catch you off guard.

* Concluding the trend of inhumanly difficult Legend-class DLC spirits, we have Sora's Nobody himself, '''Roxas'''. [[ThatOneBoss Are you]] [[VideoGame/KingdomHeartsI scared]] [[VideoGame/KingdomHeartsII yet]]? This stamina battle in the "Dive to the Heart" form of Hollow Bastion pits you against a Sora with 160 HP to your 150, as well as increased move and attack speed every so often. The trouble is, he also starts equipped with a Killing Edge, and he will heal once you get him down to 80 (all but guaranteeing that he'll be able to build up his Final Smash), [[GuideDangIt neither of which the game tells you about]]. As you'd expect, the AI is hyper aggressive, refusing to give you any breathing room. He'll use Sora's entire bag of tricks against you, flinging magic to cover any distance, charging with his Sonic Blade, and pulling out a counter if you get sloppy. And because the spirit has a whopping 13,800 power and a Neutral affinity (meaning you can't weaken him by selecting a primary of opposing type), you either use a high power spirit of your own, limiting your support options, or weaken yourself in order to get auto healing that you WILL need to compensate.

The trouble is, he also starts equipped with a Killing Edge, and he will heal once you get him down to 80 (all but guaranteeing that he'll be able to build up his Final Smash), neither point the game tells you about.

* '''Roxas''', serving as the legend spirit for the board, is a complete and utter nightmare, as befits Sora's Nobody. This stamina battle in the dive to the heart form of Hollow Bastion pits you against a Sora with 160hp to your 150, increased move and attack speed every so often, but also starts equipped with a killing edge and that will heal once you get him down to 80hp (all but guaranteeing that he'll be able to build up his final smash), neither point the game tells you about.

With the two DLC waves introduced to us by December 12, 2018 (made official by April 17, 2019), each character introduced to this game gives us their own special Spirit Board filled up with at least eight different spirits available for to go up against. Unlike the regular Spirit Board, you can go up against these spirits as many times as you need to... which is a good thing with some of these spirits being just as challenging as the spirits implemented into the game by default.

* Upgrading from Advanced spirits to an Ace spirit for this series, the '''Villager & Iron Golem''' spirit has you dealing with not just three Steve & Alex characters, but a giant R.O.B. all at once, all of whom love grabbing you and throwing you all over the stage. To make matters, R.O.B. pops up seconds after you try and fail to deal with the Minecraft characters early on and R.O.B. has super armor on him, which makes going after him a greater challenge when you also have to deal with multiple Alexes and a Steve being annoying nuisances to deal with on their own due to their ranged grabs. And for extra measure, you need to make sure you get the Cuccos to have a fighting shot against them all, otherwise, you're in for absolute Hell with this match.

* '''Pauline''' is easily the most infamous Spirit battle in the entire game, and not without reason. The map is 75m and the target is a [[GetBackHereBoss pacifist]] Peach, and her backup consists of Mario, who starts the battle with a Hammer, and a giant Donkey Kong. Sound simple on a map as big as 75m? Not quite. First of all, your jump height is reduced (though Bunny Hoods spawn for you to remedy this) while Peach runs away from you like a coward. Secondly, another item that commonly spawns is the Timer, and while you can grab it to make beating up on Peach easier, the enemies can do the same thing themselves and utterly gang up on you. And third, there's a ''time limit'' that's ''a minute-and-a-half long'' for a stage as big as 75m. It turns out that Mario and Donkey Kong are actually ''really good'' at wasting your time, with one of them blitzing you as you chase Peach while the other farms Timers. In fact, Donkey Kong will use his grapple Forward Throw and just ''hold you there'' with it, not even attacking. Alternatively, he can throw you up and actually kill you there if you're unfortunate enough with your luck. You'll almost certainly have to KO Mario and Donkey Kong before you can get at Peach with any big hits, which is a difficult task with the strict time limit and the awkwardness of 75m in mind. Compounding this is the fact that the game ''[[GuideDangIt doesn't even tell you]]'' [[GuideDangIt about Peach fleeing from you]] before the stage starts. Hope you enjoy listening to "Jump Up, Super Star!" ([[SoundtrackDissonance dissonant lyrics and all]]), because you'll be at it for a good while. The difficulty regarding this Spirit battle is so widespread that even Sakurai himself lampshaded its infamy in the Min Min showcase video, and decided to [[EasyLevelTrick show off a quick way to beat it]] [[https://youtu.be/M_NNyXaBW-I?t=1752 in less than a few seconds.]] In other words, equip yourself with a Staff spirit along with spirit that increases shooting power. You should be able to take down Peach within seconds.

* While '''[[VideoGame/JoyMechFight Sukapon]]''''s Spirit Battle isn't in World of Light, it does have a rare chance of appearing on the Spirit Board. This fight is twice as bad as Rayman because Sukapon is a Legend spirit with 13,700 power and puppets a Mii Gunner with 180 HP in a Stamina Battle. This Mii Gunner is extremely aggressive and nimble, preferring to zone you with her multitude of ranged attacks to make avoiding Sukapon almost impossible. Thanks to the enemy's high HP and [=AI=] level, it's more than likely you'll have to [=KO=] Sukapon ''twice'' before the fight is over. And to make matters worse, the Mii Gunner periodically gets a damage buff to keep the pressure on you even if Sukapon is gone. Odds are, unless you cheese out this fight by beating the Mii Gunner off one of the sides of the stage for whatever reason, you will have to buy it from the Shop when it's available and it ''costs a fortune'', that being 15,000 gold.

* Trying to fight '''Fury Bowser''' head-on is about as suicidal as it is in his [[VideoGame/SuperMario3DWorld debut game]], being one of the few Legend Spirits that were introduced via a Spirit Board Event. He's played by Bowser (duh), who is not only a Super Giant, but is also Metal on top of that, turning Bowser, who's already the heaviest character in the game, into an outright DamageSpongeBoss who can only be launched by the strongest of moves. His AI (usually) isn't as bright as some of the other Spirits on this list, but that doesn't really matter because of how the Omega Find Mii stage you're on leaves you with ''zero'' breathing room, letting him spam moves like his [[BreathWeapon Fire Breath]] and [[SpinAttack Whirling Fortress]] with no consequences. He also gets Curry Breath every once in a while, making approaching him even harder, essentially putting you in a CycleOfHurting until it ends. Almost immediately after said Cycle ends, however, Bowser will get a Sudden Final Smash too, which is not only hell to avoid, but can [[GlassSmackAndSlide slam you into the screen]] instantly if you're hit while at high damage. Be advised: Only bring the best Shield Primaries you can find, as well as some Metal Killer and Giant Killer Support Spirits, if you want even a sliver of a chance to defeat this demonic beast.
* Knocking heads with the '''E.M.M.I.''' from ''VideoGame/MetroidDread'' is an exercise in absolute frustration, especially for an Ace level battle. For starters, it's a stamina battle against a Giant R.O.B.; nothing necessarily wrong is there with that. Second, it gets increased move speed; still not a call for concern yet. Then you see it periodically becomes invincible. There, we have a problem. Then when you see the stats, you'll notice you have only 30 HP on you. Don't be fooled by it having only 20 HP by comparison; R.O.B. rapidly regains its invincibility, leaving you with only 1 or 2 seconds to actually hit it with anything at all. Combined with its high speed and tendency to grab you much like what the E.M.M.I. does in its home game, and it can quickly make short work of you even with your best spirit teams and battle items. Even worse, this is one spirit fight where you can't really cheap shot it due to it being near constantly invincible, with it's times for vulnerability also being inconsistent once R.O.B. stops being invulnerable. Not to mention certain attacks with it ''can't work at all'' because of how slow they can be to work in this battle. Hope you enjoy the horror sounding track that plays with it, because you might be hearing it a lot here.

* Woe betide those who fight the '''Mumbo Jumbo''' spirit, which sets you against a Gold Mii Swordfighter and a ''Giant Gold R.O.B.'' on the normal Jungle Japes stage. While the Mii Swordfighter is the only one who needs to be taken out to win, it loves using the R.O.B. as cover while the latter uses its size and far-reaching attacks to strike you from unexpected distances, aggravated by Jungle Japes leaving you with little area to run. And in case you felt that was too easy, just before the R.O.B. shows up, you're inflicted with the Flower effect, steadily increasing your damage when both the R.O.B. and the Swordfighter could already knock you out faster than you can say "Eekum Bokum."

* '''Donkey Kong and Lady'''. You have to beat a giant Donkey Kong with super armor in a stamina battle, and he has a metric ton of stamina and enough strength to destroy you in seconds. To complicate things, Peach is also in the fight, representing the Lady (Pauline) in question, but this time, you have to protect her along the way or you lose, and she goes out of her way to get involved in the fighting. There's also the fact that because Donkey Kong is giant, his throw power is strong enough to OHKO you if you're unable to get out quick enough. None of this is helped by the fact that you fight in the awkward to fight 75m, and unlike with the Pauline spirit, hazards ''are'' turned on this time. Solution: equip yourself with a Super Launch Star spirit and throw it in the upper-left corner. When the giant Donkey Kong appears, he'll get launched into the star, which increases in knockback power and then he'll get KO'd the second time he falls into the star. Alternative solution: try to find the right spot as Min Min (or someone else with a long grab if you don't have her) while making sure you aren't accidentally KO'd yourself and throw the giant Donkey Kong backwards out of the stage (hopefully).

* The '''[[VideoGame/DonkeyKongCountry Funky Kong]]''' Master Spirit takes place in Kongo Jungle and puts you against Captain Falcon, DK, and Diddy Kong, who will all eagerly pick up the constantly spamming Bullet Bills and fire at you with scarily competent aim. It's not much of a problem if you use a Support spirit that gives you the Franklin Badge, but you better be careful of not having an attack make you drop the Badge and have one of the enemies steal it from you. Also, watch out with where you aim your Bullet Bill if you get one yourself; one false move made can end you just as quickly as any of the CPU's Bullet Bill attacks. This is also one of the Spirit battles that unlocks a store where you can buy certain spirits ''exclusively from Funky Kong's shop'', so you'll have to earn the right to enter Funky's shop in order to complete the spirits list.

* '''Akuma''' will, for lack of a more polite term that adequately conveys how rough his Spirit Battle is, ''fuck your shit up''. It's a Stamina Battle against Ryu on the Omega form of Suzaku Castle. Now, Akuma in his playable appearances has traditionally been a GlassCannon, so you'd think that that would be the case here, right? '''WRONG'''. See, he's modeled after his original boss appearance, so he takes normal amounts of damage (and likely has more stamina than you will), and his specials are massively buffed to the point where he can quite literally wipe you out in three or four hits, his AI is fairly smart, and the fact that it's Omega Suzaku Castle means that there's nowhere to hide. And if he breaks your shield for whatever reason... say bye bye to whatever health you had left (unless you restart immediately). Not even a Critical Healing will be able to save you with this one! To add insult to injury, you must win this battle [[BeefGate in order to be able to rescue and play as Ken in World of Light]].
* '''Guile''' is a massive pain in the rear, with the battle pitting you on the Omega version of Pilotwings against an Assist Trophy Guile and Captain Falcon, the latter of whom is more than willing to get in your face. Falcon has 180 HP, just like other Legend-class Spirits, but it's him pestering your face while Guile Sonic Booms you in the interim that will drive you up a wall. Want to take Guile out with Assist Killer? ''It's freaking Guile'' -- he will merely Flash Kick you away if you don't have a whip, and Falcon can soak up projectiles like a boss. This match is a very ugly instance of CharacterSelectForcing, because mix-up and rushdown characters like Pikachu are going nowhere against this double team from hell.
* '''9-Volt & 18 Volt''''s Spirit Battle is pure agony, even on easy mode. You are put in the Battlefield form of the Gamer stage and have to fight a Villager who loves to spam projectiles, an Incineroar who likes to grab you so his teammates can rack up damage on you, and worst of all, a permanent Sheriff Assist Trophy. Sheriff's attacks are quick, have infinite range, cannot be blocked or reflected, and inflict significant knockback, and with all the enemies ganging up on you, trying to do anything without getting locked in hitstun is nearly impossible. Sure, you could try to get rid of the Sheriff first, but the Sheriff Assist Trophy is ImmuneToFlinching, very durable (although an Assist Killer Spirit can help greatly with that), and you still have to worry about the other enemies attacking you. And even a Franklin Badge or other reflector move won't work, because the game doesn't register the Sheriff's bullets as projectiles for some odd reason. Just to top it all off, the stage keeps dropping Galagas that the enemy ''will'' use as soon as they appear. Given all the attacks that keep knocking you around, it's only a matter of time until something knocks you into a Galaga or leads to an unavoidable KO ''without'' being sucked up by a Galaga. Worst of all, you could even try to use the Galaga against them, but due to the constant bullet spam from the Sheriff, the Galagas will probably get destroyed even afterwards. Your best bet is to bring in an Assist Killer spirit on a character with a counter move, use said counter move to avoid being damaged by the bullets until you can take out the Sheriff, then grab and use the Galagas as soon as they appear, and even that will probably take a dozen attempts or more.

* '''Donkey Kong and Lady'''. You have to beat a giant Donkey Kong with super armor in a stamina battle, and he has a metric ton of stamina and enough strength to destroy you in seconds. To complicate things, Peach is also in the fight, representing the Lady (Pauline) in question, but this time, you have to protect her along the way or you lose, and she goes out of her way to get involved in the fighting.

Combined with its high speed and tendency to grab you much like what the E.M.M.I. does in the base game, and it can quickly make short work of you even with your best spirit teams and battle items.

* '''Bahamut ZERO''' is another straightforward fight that regardless manages to be a major pain in the neck. You're fighting on Battlefield Midgar, and ol' Bahamut himself is played by a Giant Meta Ridley. A ''very aggressive'' Giant Meta Ridley. His AI is absolutely relentless, abusing his Giant-boosted hitboxes, obscene attack power, and great combo game in order to stunlock you into oblivion once he catches you, if not just drag you off the screen like Jigglypuff's Wall of Pain back in the days of ''Melee''. Because Ridley is Giant on a normal sized stage, it's very difficult to evade and block his blows, especially if you try to come in from above, in which case he'll happily charge an Up Smash to cover one of the platforms and KO you on the spot. His Sudden Final Smash when he's at high damage is the cherry on top, because it can instantly destroy you if you reach 100% damage, meaning trying to use Rage and Critical Health effects is a bad idea. Bring several Giant Killers with you, or Bahamut ZERO will Tera Flare your butt into next week.

* For this series, there's ''two'' Legend spirt battles awaiting you in Pyra & Mythra's Spirit Board. With the first one, the '''Malos''' spirit battle has you in the Guar Plains fighting against ''three giant Ridleys'' to start things out. While you do need to just take out the main fighter (a giant Richter with a beam sword) to win, you also need to beat at least two of the three Ridleys before you even have a chance against Richter in the first place. Unfortunately, Richter has impeccable range with his whip or beam sword to easily cause significant damage on you or knock you out quickly. And for one last kick in the head for good measure, if you both survive long enough, you also have to deal with Metal Head doing his thing on the Guar Plains as well. Good luck with that.

* '''Dr. Wily''' is the optional spirit battle of the Base, and boy ''howdy'', is he extremely tough. The fight is a stamina battle on the Omega form of Dr. Wily's Castle against eight Metal Mega Men, who will relentlessly pursue you with deadly ranged attacks, with a combined total of a monstrous 800 HP. Wily himself isn't too tough due to just being a single Dr. Mario, but the battle to get to him is extremely difficult. Make sure you go in with a Franklin Badge, because otherwise you're going to have a bad time.
