Willfully Weak

"NJ: Who are you, where did you come from, and how powerful are you? Aerynn: I don't know! NJ: Don't know WHAT? Aerynn: How powerful I am! I don't know! NJ: How can you NOT KNOW SOMETHING LIKE THAT?? Aerynn: Because there are a lot of things I'm afraid to try!"

- Electric Wonderland, Day of the Fools

A Power Limiter in which a character is intentionally suppressing their true strength, be it by magic, technology, willpower, or just by not powering up. Can be for all sorts of reasons. Maybe they want to give their opponent a fair shot at winning. Maybe they don't know their own strength, or letting loose would simply uncork their Power Incontinence. Maybe they just want to be normal. Maybe they are afraid of the collateral damage. Maybe they want to try this Weak but Skilled thing so they learn to fight tactically rather than steamroll others with brute force. Or maybe it's just to keep their power from overtaking the plot.

Whatever the case, they have decided to be Willfully Weak. To be clear, this is NOT faking it, or merely going easy on their opponents. The character actually is as weak as they appear... but only because they choose to be. They could stop suppressing their powers at any moment and suddenly be an unstoppable powerhouse. Of course, given the possible consquences of them using what they normally keep under wraps, it's not always a "choice" made lightly.

Obviously, what is considered weak varies greatly from story to story. In some stories, they'll be almost the Muggle. In others, they'll actually be quite powerful, but far behind the other supers. In still others, they'll actually not be weak or normal at all, and be one of the more competent fighters, but nowhere near what they'd be capable of without this self-imposed limitation.

This trope, for obvious reasons, often applies to gods in human form.

May be caused by Normopathy. May lead to a World of Cardboard Speech or to the discovery that I Am Not Left-Handed when the crossing of the Godzilla Threshold means it's time to get dangerous and show their true power. Rarely (if ever) leads to Always Need What You Gave Up, because when they choose to limit their powers for mundane reasons, they can just make an exception, and in cases where their reasons are more dire, well, losing the fight is better than blowing up Main Street. Despite similarities, not likely to overlap with Just Toying with Them, as characters doing that don't care too much about playing fair and maintaining their self-imposed limitations. In videogames, compare Cherry Tapping.

This can overlap with Fights Like a Normal for a character that usually suppresses all fantastic powers and fights as a Badass Normal.

Anime and Manga
"Piccolo: Don't think you have the upperhand yet. I'm still wearing weighted armour!
 * Washu from Tenchi Muyo!. She's
 * And as she demonstrates in the second OAV, "weak" is a very relative term. Even with her powers restricted, she's much stronger than Ryoko, who, prior to Washu's appearance, was arguably the single most powerful cast member other than Tenchi himself.
 * Then again, Ryoko only had one out of three jewels, Tenchi didn't let her have the others, even when giving them to her would have been a good idea, making her a partial example.
 * At least, it would've been a good idea for him to give one more of them back to Ryoko. Giving her all three would, barring a different compatible power source being found for his grandfather's royal tree (and it's unclear if such a thing even exists), have a rather adverse impact on Yosho's health.
 * Later on GXP shows that Tenchi starts doing this himself since he, like his grandfather, prefers living simply without the responsibility of running the galaxy.
 * Dragonball Z's Goku in the tournament with Uub, a human who (due to being the reincarnation of the most powerful alien Goku ever fought) has serious potential to become a good fighter again. Normally, when powered up, Goku has the power to destroy entire Planets with the flick of a wrist, but in this case remains at a more merciful Power Level to allow Uub an actual chance. The battle is fairly fierce, because, while Uub is really just slightly above Badass Normal status at this point, the powered-down Goku is too.
 * This is further implied with Vegeta's statement that when Goku is finished training Uub, he'll fight him again, and "need an entire planet as the arena".
 * Another DBZ example: Frieza limits his power because his body can't take it. Goku even uses this to his advantage, walking away from the fight.
 * Actually, what happened is that Freeza maxed out his power, which he rarely does because of the risk to his body, to prove he is stronger than Goku. The result was fairly predictable; Freeza reached Goku's power, but his stamina decreased much faster, and took more damage. Goku noticed this, and growing bored of the fight, decided he's proved his point to Freeza, before walking away from the fight.
 * Yet another DBZ example: When Goku fights Vegeta the second time, in order to have a more even fight, he decides not to use Vegeta finds out about Goku's self-imposed limit later on. Needless to say, he is less than happy about it.
 * Gohan is depicted as having the potential to become, quite literally, the most powerful warrior in the entire universe if he wished (and he actually does so a couple of times), but is a pacifist by nature, only fighting when someone needs his protection. Typically, his true strength only reveals itself through Unstoppable Rage.
 * In Dragonball, Goku's fighting in a tournament and reveals suddenly that he's wearing extremely heavy clothes, as part of his training. And is suddenly a lot faster once he gets rid of the extra weight. The same thing happens again several times, all the way up to Goku's fight with Frieza, at which point everybody is so strong that weighted clothes are no longer enough of a Power Limiter to bother mentioning.
 * Lampshaded in The Abridged Series, during the battle between Piccolo and Freeza:

Freeza: Weighted armour? How quaint. And how much does it weigh?

Piccolo: Same as it always does: one hundred kilo-

Freeza grins

Piccolo: ...Oh.

Freeza: That's just cute!

Piccolo: That concept just sort of lost meaning after a while, didn't it?"


 * The title character of Naruto could kill himself if he ever uses his full power.
 * He could kill a lot more than that if he ever loses it...
 * Rock Lee wears weights on his legs to reduce his speed. He takes them off during the fight with Gaara. Unlike Naruto, Lee is not host to an apocalyptic demon, but he has learned techniques that, if abused, could kill him. His sensei forbids him from using even the most basic of these techniques (which they share) except in a dire emergency.
 * When Lee takes off the weights for the first time, several characters scoff at the idea that it'll make a difference against Gaara. Until the weights hit the ground and produce substantial craters, implying that Lee must have been wearing a few tons of weights. Which really ought to have resulted in massively powerful kicks while he was wearing them. To be fair, the problem wasn't that he wasn't kicking hard enough. He simply wasn't fast enough to get around Gaara's sand barrier with the weights on.
 * The title character of Flame of Recca as well as his older brother Kurei and any other Flame Master must wear seals on their arms to protect their already fire resistant selves from the power of their flames going out of control and burning them to death.
 * Bleach
 * Kenpachi intentionally handicaps himself by wearing an eyepatch that not only inhibits his field of vision but also significantly drains his spiritual pressure. Even with all of these impediments, he can fight on-par with other Captain-level opponents, even when they release their zanpakuto in either shikai or bankai form. He also wears bells in his hair so trained fighters will always hear him coming. He does all this just so the fight will contain the slightest hint of a challenge, so the fight can be satisfying. He also swings around a two-handed sword with one hand wildly. When he applies proper sword techniques using TWO HANDS, he gets that much more dangerous.
 * Madarame Ikkaku from the same division refuses to use his bankai, because he doesn't want to be promoted out of his division on out of Kenpachi's leadership.
 * Yumichika's shikai has a dual Energy Absorption and Vampiric Draining effect. Whenever he uses this power, he wins the fight in a single strike. Unfortunately for him, it's a kidou type sword, which is taboo in the very same Eleventh Division, so he never uses it when anyone from Eleventh could find out. When there are witnesses to a fight, he uses a nickname for his sword and a fake shikai command, to annoy it so that it will merely transform into a multi-bladed sword with no special abilities. Even when not using any special abilities he's considered on a par with lieutenants.
 * Ichigo gets a moment of this fighting a Privaron. He's reluctant to release his now-controllable Super-Powered Evil Side as he knows that it will leave him weaker for later fights, and also knows that he's going to hit problems if he's releasing it this early on. He's eventually forced to release it, turning a near-defeat into a Curb Stomp Battle. Normally though, Ichigo fights at full strength.
 * Remember kids: the only reason that Orihime is not slicing through people as tough as Aizen or Yamamoto is because she is an Actual Pacifist with self-esteem issues.
 * We learn in the anime that the reason Harribel's abilities are so underwhelming compared to her rank and supposed status as a Vasto Lorde is because she refuses to eat other Hollows, the method that makes Hollows and Arrancar stronger. She also mentioned that she sort of looks down on those who do.
 * Rider, from Fate/stay night, has an ability called Monstrous Strength, which would allow her to increase her STR parameter by a whole rank for a period of time—which is no small advantage. She never uses it, however, because
 * Likewise, she always had herself blindfolded, which prevents her ability Mystic Eyes to run amok (if not blindfold, a pair of glasses). What does it do?
 * She has another case of holding back and make herself look like a weak Servant: she just dislikes using full power when her master is Shinji. On the other hand, when her Master is the real one, it's a different story: Still no Monstrous Strength, but removing blindfold becomes a viable option.
 * Aki Izayoi/Akiza Izinski in Yu-Gi-Oh! 5D's wears a hair curler which supposedly keeps her psychic powers in check, although whether or not this is a Magic Feather has yet to be seen.
 * Easy enough to not notice, but in the original Yu-Gi-Oh! Yugi's duel with Rebecca Hawkins was one of the few duels where he didn't transform into Yami Yugi. The idea was that Rebecca wasn't a villain trying some sort of underhanded tactic, but merely an opponent who accused Yugi's grandpa of stealing from her Grandpa.
 * This was also part of the backstory behind the monster card Gearfried the Iron Knight, as told by Joey. He was once a mighty swordsman whose power was so great that he could level entire cities simply by swinging his sword. In order to protect those around him, he donned a suit of iron armor that would limit his power.
 * In a season two episode of Yu-Gi-Oh! GX, Shou Marufuji/Syrus Truesdale removes Power Bond (a spell card that doubles a Machine-type Fusion monster's attack power, then cuts the user's life points by that monster's original attack) from his deck to prove he can still win without it.
 * Belldandy and her sisters in Ah! My Goddess.
 * Lind fights almost solely using a massive axe. Without the axe she is significantly stronger, even without removing her Power Limiters.
 * All goddesses and demons have to limit their powers when acting on Earth, to avoid causing collateral damage (demons care about this too, because they don't want to kill off their potential clients). Hild, the leader of the demons, is so powerful that she has to wear at least twenty Power Limiters to safely travel to Earth.
 * Negi in Mahou Sensei Negima at one point decided that he would seal his magic and fulfil his duties as a teacher without relying on magic. He chose a bad time for it.
 * Sailor Saturn in Sailor Moon. If she uses her most powerful, canonically nameless attack, she will die. And destroy the world.
 * Hagi from Blood Plus does this and refuses to utilize his true Chiropteran form because
 * Actually, he can't use his true Chiropteran form
 * The lethal fighting styles of the Saotome school in Ranma ½, Yamasenken and Umisenken, were sealed on their practitioners' honor at the end of their story arc. They could let Ranma become completely undetectable (by sight, sound, heat, or even Battle Aura), toss Razor Wind to demolish enormous bronze statues, rip out opponents' hearts, strangle them, or pierce their backs—but he won't use even the basic "invisibility" skill, not even against powerful foes when nobody would have blamed him.
 * Let's not forget that Genma came up with these techniques in the first place. Yes, the same man who actually fell for the Nekoken, alias "Cat Fu", aka "the poster child for the difference between real Training From Hell and torture". Of course, he already lives up to this trope by virtue of the fact he's at least on the same level of skill as Ranma, if not higher (the guy did train Ranma to be where he was at the start of the series, after all), yet he refuses to fight anyone.
 * Saint Seiya's Gold Saint Virgo Shaka deliberately keeps his eyes closed when he battles his foes -- his constant meditation means that he devotes only a fraction of his attention to the outside world. People who know him, even fellow Gold Saints, are very afraid of him opening his eyes, because that means he has stopped meditating and is now fully focused on the enemy.
 * To be accurate, the main reason Shaka suppresses his eyesight on his own is to further his seventh sense and cosmic perceptions, which means a tremendous power increase compared to his other fellow Gold Saints. The result of him opening his eyes is the brutal release of all of the accumulated energy in a blow that literally beats his opponents senseless.
 * To give an accurate assestment of his power, with closed eyes he was on par with Aoilia, who, when fighting seriously, curbstomped a Seventh Sense-wielding Seiya (and didn't kill him outright because he was under a brainwashing that made him a sadist and wished to torture him).
 * Another Saint Seiya example would be Bronze Saint Andromeda Shun; he literally refuses to wound others or take a life, even when the circumstances call for it, and gets called out on it several times by his foes. There is a theory that he actually mastered the seventh sense (though the fact is never openly stated, it is still highly believable) way before anyone else but always refused to use this tremendous power because of the havoc it could wreak. The first to actually see this is his master to whom Shun said he wanted to show his true power, and his Silver Cloth (remember, Shun is supposed to be a mere Bronze Saint) gets blown to ashes by an imperfect blow ; the second one to see it is Pisces Aphrodite once he ripped Shun's Cloth and chains off his body, forcing him into unleashing the Nebula Stream and Storm. Cue the Oh Crap look on his face when he realizes he sort of just removed Shun's wards.
 * Most of the Gold Saints when faced at the Twelve Temples may be an example for reasons different for all Saints: Aries Mu either didn't fight them (manga) or gave them a couple slaps merely to prove they needed to have their cloths repaired; Taurus Aldebaran had doubts on the Pope, and never pressed his advantage when fighting Seiya before conceding the battle; Gemini Saga limited himself to illusions and dimensional tricks  before being forced to stand down by  ; Cancer Death Mask didn't take Shiryuu seriously for a single moment until the latter actually accessed to the strenght granted by his Seventh Sense, thus failing to block or dodge the decisive blow; Leo Aiolia had got brainwashed, and decided to torture Seiya to death instead of killing him fast; Virgo Shaka, as explained above, ALWAYS meditates, and it takes Ikki's continuously surviving his attacks to get him to open his eyes and get serious; Scorpio Milo didn't want to kill the Bronze Saints, and held back to try and force them to surrender; Capricorn Shura actually did NOT held back, failing to stop Seiya, Hyooga and Shun only because Shiryuu thwarted his strategy to line them where he needed them to kill all four with a single strike, and then curbstomped Shiryuu, who had to resort to Heroic Sacrifice to kill him; Aquarius Camus was interested only in testing Hyooga's power, and, after letting Seiya and Shun pass, never pressed his initial advantage (and was quite happy to find that Hyooga had managed to become even more powerful than himself); Pisces Aphrodite, in the end, was just too confident in his roses, resulting in him letting Seiya go in a path filled with poisonous roses (to be fair, only Marin's arrival saved Seiya from death), and trying to simply disarm Shun so he'd stop attacking and die due being poisoned at the start of the battle instead of killing him outright, with the results illustrated above.
 * Katanagatari has a two examples:
 * The first is a particularly crazy example (warning: spoils an awesome twist).
 * The other is Shichika himself. He's given orders by Togame to protect the swords, Togame, himself, and himself, which proves to make some of the fights more difficult. In the last episode,.
 * Fai  from Tsubasa Reservoir Chronicle had a tattoo on his back that limited his magical power,  . Once Yuuko took this away as his price, Fai resolved to never use his magic again because he was too powerful without the limiter.
 * In Yu Yu Hakusho, the last episode focusing on Kurama in the series had him deal with this consideration while balancing his three personas. Ultimately, he
 * Raizen is dying when we meet him, simply because he hasn't eaten any human flesh in hundreds, if not thousands of years He's still the strongest character in the series when we meet him, so it's an interesting case.
 * Rei Ayanami. Ordinary High School Student, right? In episode 24, it is revealed that she's just as powerful as the final Angel, if not more. She was just hiding it out of orders.
 * It's heavily implied in Star Driver that Takuto employs the bare minimum of his abilities to win fights against the Glittering Crux. His fight against Benio in episode 13 demonstrates exactly why he does it: once your opponent knows your best moves, they're going to make damn sure they have a counter for it by the next fight.
 * Rurouni Kenshin is this throughout the series. Several opponents try to get him to revert to being the Battousai and unleash his full power, but he is very resistant to this. The closest we see to his pull power is in the fight with Shishio.
 * Correction: The closest we see to his full power while willing to kill is the fight with Saito. In the fight with Shishio, Kenshin is exhausted, injured, and still not willing to kill.
 * Seijuro Hiko's cloak is heavily weighted to restrict his movements, and brightly colored to alert others to his approach, so that his opponents will have something resembling a fighting chance, since without it.
 * Alucard from Hellsing. His powers are limited by magic to his current need. When he faces an enemy that is too powerful for his current level, he unlocks additional levels and increases his power. Given that he's a Blood Knight, he's particularly gleeful when he finds powerful foes who allow him to unlock his full, terrifying potential.
 * In Trinity Blood, Abel Nightroad rarely uses his Crusnik power at more than 40%, which is usually sufficient. 80% power is reserved for people who really need their ass kicked. As for 100%... well, there's a reason why he's the brother called Abel.
 * In Baccano!, the omniscient, reality-warping Eldritch Abomination known as prefers to not tap too much into his godlike powers if he can help it, and even ignores his own omniscience. This is largely (if not entirely) to keep himself from going entirely insane with boredom.

Comic Books

 * Superman is always doing this because he's so powerful, the rest of the world may as well be made of cardboard, and the slightest lapse in control on his part could kill someone. When the modern Kara Zor-El (Supergirl) arrived on Earth, it was thought she was actually more powerful than Superman. Superman had been holding back so long it seemed that even he forgets what he can do when he lets go. She caused a lot of property damage in the early issues. (It seems she does still have the edge in flight speed, whereas he has an edge in strength and toughness.)
 * Mr. Mxyzptlk has way more power than he can safely use—modifying the universe too much would damage its structural underpinnings. Very, very bad things happened in a storyline where he accidentally gave 99% of his power to the Joker.
 * Spider-Man usually pulls his punches to avoid seriously injuring the people he fights. It's subverted in Spider-Man vs. Wolverine when he accidentally kills an assassin...who happens to be Wolverine's ex-girlfriend.
 * Same with Captain Britain, who learned about all this while teaming with Spider-Man. Half-canine criminals don't deserve a max-power punch in the snout (Doggy-girl survived, her bills paid by the Cap).
 * The Sentry is an example of this as well. The more power he uses, the more insane he gets. When he is finally allowed to cut loose on the Hulk in World War Hulk, he loses control and becomes a bigger threat to the world then 'the worldbreaker'.
 * Thor, the Norse god of thunder, has to intentionally hold himself back when fighting due to him not wanting to kill his enemies, make his friends feel weak in comparison or harm a lot of innocent bystanders and cause huge collateral damage.
 * Jaime Reyes, aka Blue Beetle, regularly has to talk his suit down from using its more lethal abilities. It's implied that the suit's abilities go as far as deicide.
 * The Silver Surfer could end a fight with even some of the strongest supers Marvel has to offer in seconds. But he is usually not in the mood for fighting, considering it to be the habit of madmen. But heaven help you when you do piss him off!

Film

 * The Adventures of Baron Munchausen. Berholdt chains himself with iron cannonballs to prevent himself from moving too fast.

Literature
"Dumbledore: "You flatter me. Voldemort had powers that I will never have." McGonagall: "Only because you're too... well... noble to use them.""
 * Though far from weak, Albus Dumbledore from Harry Potter outright admits to limiting the power he could reach, in the first chapter of the first book:


 * It turns out.
 * At the end of Michael Crichton's Sphere
 * At the start of The Hollows Rachel is doing this, by doing only white earth magic spells. White spells are less powerful than black spells, and the line is clearer with earth magic than ley line magic. However, circumstances keep forcing her to use black magic.
 * Subverted later in Black Magic Sanction where it is shown white magic can be as strong as black magic, but requires greater skill to do so. Rachel isn't much for studying though and thus chooses to use black magic as a short cut when she needs power. This is beginning to have some rather negative long term implications.
 * In Warbreaker  He can, of course, unleash it whenever he wants. He's pretty badass even without it, though.
 * Because he hates so much that he has it, the only time in the Knight and Rogue Series that Michael uses is when he's in a life or death situation and activates it without thinking.

Live Action TV

 * In the episode "Hide and Q" of Star Trek: The Next Generation, Riker is given Q-powers by Q. Picard, distrustful of Q's motives, makes Riker promise not to use his new powers, no matter how much he might be tempted to. Riker even allows disaster victims to die rather than use his new powers, even though it upsets him deeply.
 * In an episode of Lois and Clark, an unusual heat wave has hit Metropolis, and Superman is blamed for it. He goes before the court and is accused that his rampant use of non-human powers is having unintended effects on the environment. The judge orders Supes not to use his powers. As soon as he leaves the courtroom, a thug breaks free from a cop and manages to grab his gun. Superman immediately uses his Eye Beams to make the thug drop the hot gun... in full view of the judge, who orders Superman arrested, as he can't even avoid using powers for 5 minutes. Of course, it turns out the heat wave is caused by Lex Luthor.

Video Games

 * Possible Sonic the Hedgehog. In many games he seems to just move fast enough to get through a situation and show off, but we can judge by other games and various cutscenes that he much faster than he lets on.
 * Joshua from The World Ends With You. He's not a very good fighter at first, but then you find out that all along, he's been able to shoot beams of angels out of his phone... he just chose not to. Because he doesn't like working up a sweat.
 * The player (as in, the one holding the DS) can also do this, intentionally lower one's level in exchange for a higher drop rate.
 * According to Word of God, Alice Margatroid of Touhou always holds back in her fights because she doesn't know what she would do if she ever lost while at full power. A big clue to this is that she's always carrying a grimoire, which is always bound up; she fights with her dolls instead. The last time she opened the thing, she was an Ex-Boss. Since then, it's always been seen closed, and she's a 3rd-to-4th-stage boss instead.
 * Eirin Yagokoro is also said to be actually far stronger than Kaguya Houraisan, but holds back her power out of respect. Though she doesn't always do a great job of holding back.
 * Hong Meiling is probably the most obvious case: using her to win against Sakuya in Hisoutensoku has her bluntly stating that she was always going easy all the time, and that she will only fight seriously if it was an official duel she was involved in.
 * Both Suika Ibuki and Yuugi Hoshiguma intentionally only use a small amount of their immense strength when battling. This is both because they're Boisterous Bruisers that are far more interested in fighting a Worthy Opponent than in actually winning, and because they are powerful enough to tear apart mountains with their bare hands so using their full strength is a Bad Idea for everyone involved.
 * Not to mention Yukari Yakumo, who Word of God has stated has enough power to "easily" destroy Gensokyo, and is quite possibly the most powerful being in the Universe, yet manages to put up challenging yet doable fights in the games. The fact that she's generally too lazy to go all-out is probably a factor too.
 * Tenshi Hinanawi, a celestial, was defeated by almost every character in Scarlet Weather Rhapsody in their respective scenarios, but in those scenarios, she was holding back her real power in her battles on purpose, because due to being a celestial, she wasn't supposed to fight with people from the lower world, like the people and Youkai in Gensokyo, and even then, she was just bored, so she let them win. Cue Tenshi's scenario, where she wasn't holding back her real power, and she proved it by defeating easily each opponent she faced,.
 * And in Ten Desires,.
 * Frankly, the entire cast could be considered this. The fighters are using a formal dueling system (which everyone knows, somehow) that allows them to resolve conflicts without severe injury. Nearly all the enemies you fight in the main games would still be perfectly capable of continuing to fight, or even completely outclass the PC, if they weren't bound by the rules.
 * As an example, one character's unique power is to destroy anything, while another can freeze time. The former doesn't use the power at all when you fight her, and the latter uses it to instantly fill the area with throwing knives rather than just flying over and stabbing your character while they can't react. Another character has the power to instantly kill anything (naturally, this power is never used), and one has the power to...well, do pretty much anything. Oh, and the main character? Just the power to turn immune to damage at will indefinitely.
 * Before the spellcard system in the Windows games, Rikako Asakura from PC-98 exclusive Phantasmagoria of Dim. Dream was this. According to the victory quotes of other characters, she's magically talented and could probably wipe the floor with whoever she wanted... but she'd rather do science than magic, and shuns magic entirely. This gets her branded a heretic, and confuses the hell out of the scientists who came to Gensokyo to study magic.
 * Regal from Tales of Symphonia keeps his hands bound throughout almost the entire game, choosing to fight instead with his feet. It is revealed in a flashback that
 * Arcueid from Tsukihime is quite possibly the most powerful being in the world. She has insane strength, speed, and power. She can cause anything possible within the rules of the world to happen with a mere thought. However, she has to devote most of her power to suppressing her Vampire bloodlust. If she was to ever to release herself and use her powers to the fullest, she'd become an insanely powerful monster that kills everything in sight.
 * Castlevania: Aria of Sorrow. The one reason why you, are able to bring Julius Belmont to his knees is because he sensed Soma's soul . Imagine how fast you'd die if a badass like Julius WASN'T holding back.
 * Valvatorez from Disgaea 4: A Promise Unforgotten was once an infamous tyrant, but decided to abstain from drinking blood (He uses sardines as a replacement) as part of a promise he intends to fulfill, even though it would weaken him. As a result, he ended up falling from his position of power, and got stuck with a low class job as a Prinny instructor, but it doesn't seem to bother him one bit.
 * Then we meet DLC Tyrant Valvatorez. The difference is... noticeable.
 * Machoke wears a belt to weaken its power. Depending on which Pokedex entry you believe, either it needs the belt so that it can control its movements, or it would be unstoppable without it.
 * Slayer from Guilty Gear XX is an ancient, possibly thousands of years old vampire and the former head of a major guild of assassins. His Instant Kill move involves him landing a single punch at his full strength, which has sufficient force to knock his opponent into a neighboring galaxy. Despite this, he has no particular desire to kill anyone, and intentionally avoids using his full power because doing so would take all the fun out of fighting. If beaten, he simply lies on the ground, smoking his pipe and looking vaguely amused.
 * Potemkin is considered a One-Man Army by many, but in-game he wears a Power Limiter around his neck to prevent casualties (he's investigating, you see.) His Instant Kill involves him removing the restraint and landing a single punch.
 * From Guilty Gear's Spiritual Successor, Blaz Blue, there is Rachel Alucard, a bored vampire who treats every match as a Self-Imposed Challenge. Only her throw move involves actually touching her opponent; a weak-looking but damaging backhand slap. All her attacks, special movement and even guarding are handled by her familiars Nago and Gii, a cat and a bat.
 * As, the gloves come off, although even then she does nothing that would risk making her sweat.
 * Ragna does this as well, and it is only once he uses the Azure Grimoire that the time loop is broken.
 * Terumi is apparently even stronger than Rachel, as his presence causes her to lose her cool, and writes off the boss battle with him as just a warmup.
 * Rachel actually says in her story mode that she is stronger than Terumi, but nevertheless incapable of killing him permanently. On that note, Terumi is an example of this trope in his Hazama guise, since he is simply using the Ouroboros Nox Nyctores and some butterfly knives rather than his true abilities.
 * Notably, Hakumen is an aversion. In Calamity Trigger he only ever fights at 20% of his full power, but this is neither self-imposed nor willingly. It's because 80% of him are stuck in The Boundrary. He appears to be slowly regaining those percentages over time.
 * Oro from Street Fighter III is stronger than the rest of the cast, possibly combined. He keeps one of his arms in a sling in order to even the odds. Series Badass/Arrogant Kung Fu Guy Akuma/Gouki challenged him once with neither holding back their power, and they were equally strong.
 * On that note, so too is Akuma, both in and out of gameplay. Out of game, he never uses the full extent of his power because he seeks a challenger worthy of his skill so he wants to match mettle with the best without destroying them at the full depth of the Satsui no Hadou. In-game, his vitality and stun are typically lower than any of his opponents for reasons of balance (to see when he is NOT balanced like this, his original playable appearance in Super Street Fighter II Turbo is such).
 * Seth, much like the Rugal example below, plays nice in the first round but will turn up the heat once he's been smacked around. Teleport Spam and priority abuse coupled with nasty damage makes him an SNK Boss through and through.
 * In The King of Fighters '94, Rugal doesn't use any special moves in your first fight with him. Win that fight, and he shows amusement before dusting himself off and fighting you again... with all special moves on. In the process, he sets the precedent for the SNK Boss lineage after him.
 * Proud Warrior Race Guy Arthur from Tears to Tiara.
 * Ike's father in Fire Emblem Path of Radiance, cut the tendons in his right arm, and refuses to fight with a sword  when he touched Lahrain's Medallion.
 * Mega Man, in all of his incarnations. All of them are said to be the pinnacle of artificial life and combat designs for their respective universes. Through use of their signature ability could easily become nigh unstoppable. Fortunately, they all share a Martial Pacifist philosophy, and deliberately drop all but the most minor upgrades they gain after defeating a major threat to ensure that they are never corrupted by power.
 * Luigi of Super Mario Bros.. It's been confirmed that he's more powerful than Mario but lacks the confidence and control to use his powers. It is also seen in-series with his jumping ability, which is usually shown as just higher than Mario's, but he can jump MUCH higher if the situation calls for it.

 * In El Goonish Shive,  is half immortal and very powerful—but not allowed to interfere with mortal events. Mostly. Unless you're stupid enough to press his Berserk Button.
 * Grace! She's an atrociously powerful alien hybrid, and a kindhearted pacifist. She has to study martial arts with Sensei Greg so she can fight non-lethally.
 * Aerynn from Electric Wonderland practices a brand of magic that no one else in Cyberspace can do, and often feels too scared to use it to its full potential. Considering how much she doesn't mind doing (transforming her teammates, teleporting enemies, using Hammerspace to sneak her boss past security, the list goes on and on), one can only imagine what powers she doesn't want to use.

Western Animation

 * Justice League Unlimited has The Flash's secondary ability, which you almost never see: he can vibrate at an incredibly fast rate, creating an unstable resonance. When he ends up swapping bodies with Luthor Luthor uses this ability without restraint in order to blow up huge areas of the Tower.

 * Tennyo, in the Whateley Universe, is doing this now. Over Christmas, when she went all out to save her family, she ripped a hole in space-time which kept getting bigger, and she shredded an auditorium with her Reality Warper abilities, and she made a huge area radioactive too. Oops. So she's deliberately toning it down now.

Real Life

 * Germany may be an example of this considering its population could support a much larger army, and it could have nukes in a week if it wanted to.
 * Japan is a similar situation. Both are essentially due to the aftermath of World War II, a combination of limitations on their military enforced by other nations and the aversion their populace has to a more martial lean after the devastation the war wrought on them.
 * Japan even protested the US putting nuclear-powered vessels in their harbors, as the very word "nuclear" gives them shudders. They are the only country to be on the receiving end of a nuclear attack, after all.
 * Myke Tyson, of all people, could have been this as a child. The book "Momentos Trágicos del deporte" (tragic moments in sports) describes him letting people push him around and going home crying for being bullied. That kept going on until the day somebody thought it was a good idea to mess with his pigeons and made him burst into a fighting machine.
 * Some hunters prefer to use bows because its the "oldfashioned way", varying from super-modern bows with crazy sights and razor arrows, to old fashion wood and string with feather-fletched arrows.
 * Chinese renminbi. The government enforce it that the exchange rate of renminbi lower than its real value. The purpose is 1) to make Chinese goods very cheap when exported, 2) immunize the renminbi against the Western's casino capitalism. So far it has been Super Effective.
 * It's also so they can make sure the money in the hands of their populace(from what little wage they make) is practically worthless and has no buying power.
 * Some martial arts, like Tai Chi, has this. Tai Chi practitioners generally limit themselves to slow, graceful movements that look more like dance than art. This has the advantage of helping to improve form, enhance mastery and even help condition the body as very slow movements are harder to to do than fast or regular movements (for reference, try taking 2 minutes to sit down and stand up instead of 2 seconds). When its time to get serious though, Tai Chi masters are a wonder to behold.
