Hot-bloodedness is such a force in works featuring HumongousMecha, it may as well count as a power source. And as you'll read below, sometimes it does!

----

* The ''{{Mazinger}}'' saga offered the earliest examples in this section:
** The earliest anime/manga example and likely the TropeCodifier for this special media is ''Anime/MazingerZ'', the series that codified the SuperRobot. Kouji Kabuto is generally the character that all other HotBlooded characters come from (and Sayaka the role model for all HotBlooded, {{Tsundere}} female leads). We HAVE to thank Creator/GoNagai for paving the way for all the hot blooded passionate GAR-fueled heroes that we respect love and admire to this day.
** Like Tetsuya Tsurugi and Jun Hono from ''Anime/GreatMazinger''. Tetsuya, though, is a {{Deconstruction}}: his hot-bloodness is due to inner tensions and feelings of inadequacy and lack of self-esteem -due to childhood trauma- that make him being hot-tempered, impatient, hard-headed, arrogant, reckless and very hard to deal with and work with.
** And Duke Fleed [[spoiler:-and his little sister Maria-]] from ''Anime/UFORoboGrendizer'', although he can also be quiet and calmed when nothing is riling him up. However, when he WAS riled up, he fits here squarely. It is reinforced in the original manga, with the narration stating his fury burned throughout him.
** Go Nagai in fact loves HotBlooded characters. Even his MagicalGirl ''Anime/CuteyHoney'' is HotBlooded. Go Nagai characters border on the line of Hot Blood Overdose, which may lead to such noticeable side effects as sketchy art style, crazy eyes, and lots of breaking of the laws of physics.
** ''Anime/ShinMazinger'' has plenty of HotBlood, being a Mazinger show. The show's ''{{Narrator}}'' somehow outdoes the actual pilot's efforts. '''[[http://www.youtube.com/watch?v=FDj1KTha8go&fmt=18 "ZEEEEEEEEEETTO"]]'''
*** And ''ShinMazingerZero'' seems to take this trope UpToEleven.
* ''Manga/GetterRobo'' requires not one, not two, but ''three'' hotblooded pilots, and exposure to Getter Rays brings out the burning passion within oneself; even watching or reading ''Manga/GetterRobo'' can make someone HotBlooded.
* Hiroshi Shiba from ''Anime/KotetsuJeeg'' is a GoNagai character, so that being HotBlooded is a requirement.
* The ''Anime/RobotRomanceTrilogy'':
** Hyoma Aoi from ''Anime/CombattlerV'' simply ''can't'' stay calm or quiet. He is so HotBlooded that, when [[spoiler:TheDragon shot his arms off]], he still tried to crawl to his vehicle's cockpit, demanding to be allowed to pilot.
** Kenichi Go from ''Anime/VoltesV'' outdoes Hyoma. You only have to watch the scene where he and his brothers finally learn about his father's past. He swears loudly to defeat the enemy, while shedding plenty of ManlyTears.
** Kazuya Ryuuzaki from ''Anime/{{Daimos}}''. His emotions are not like a flood; they are like a bloody ''tsunami''. When he is in infatuated, he walks over with a silly, fond smile. When he is upset and sorrowful, he sobs loudly, cries ManlyTears and even punches walls. [[BewareTheNiceOnes When he is ''pissed off''...]] don't bother writing a will. There will be nothing left of you after he is through with you. And God helps you if you make Erika upset...
--->'''Kazuya''': The Baam-Seijin are not monsters, Miwa... YOU ARE!
* ''Anime/ScienceNinjaTeamGatchaman'': Joe ([[DubNameChange Jason]]) Asakura, TheLancer, was the most hot-blooded by far: a hot-tempered, emotional, impulsive, impatient, arrogant BloodKnight and trigger-happy TheGunslinger whom [[FiveManBand his own teammates]] had to hold back from attacking the enemy. His hastiness and impatience caused conflicts in the team and [[LeeroyJenkins often got them in troubles]]. And after the first series, when [[spoiler:he got turned into a cyborg,]] he became even ''more'' reckless and ''more'' violent, since he knew that [[spoiler:his cybernetic body could withstand insane amounts of punishment,]] hence he could get away with even more dangerous stunts.
* ''Anime/TengenToppaGurrenLagann'' literally ''runs'' on Hot Blood- the mecha in the series are fueled by the pilot's "will to fight". The characters themselves often point out that various actions wouldn't work if they didn't will them to do so.
-->'''Kick logic out and do the impossible! That's how team Gurren rolls!'''
** ''[[HighSchoolAU Guren Gakuenhen]]'' has '''NIA''' going hot blooded!!!
** How hot is Simon's blood? Well, [[spoiler:in the CompilationMovie he turns it into a drill and kills the BigBad with it.]] Yes, you read that right.
** Lordgenome, who is so hot blooded, he has a tendency for parts of his body to [[AwesomenessIsVolatile spontaneously erupt in flames whenever he fights]].
** Kamina is pretty much this trope personified. He brings us most of the quotes people use when describing the series(which itself may as well be called "HotBlooded: The Series"), such as "Don't believe in yourself! Believe in the Kamina who believes in you!" or "Kick reason to the curb and do the impossible!" the list goes on.
** Viral definitely deserves a mention. As a beastman, he's unable to generate Spiral Power... and then he becomes so HotBlooded he does so ''anyway''.
* Banjo Haran from ''Anime/{{Daitarn 3}}'' contains this in dangerous quantities. He even tells the ghost of his dad to piss off, cause he don't need his help to win!
* ''Anime/GaoGaiGar'''s Guy Shishio makes the most of it by piloting a HumongousMecha powered by his own courage. You could make a case for half the GGG, actually, but Guy does most of the fighting.
** In fact, most people voiced by NobuyukiHiyama have a tendency to fall into this trope, which also includes Ikkaku Madarame from ''Manga/{{Bleach}}'', Harunobu Madarame from ''Manga/{{Genshiken}}'', Viral from ''Anime/TengenToppaGurrenLagann'' and Akutare/Axel from ''VideoGame/{{Disgaea 2|CursedMemories}}''. Even Link in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' (who was voiced by Hiyama for that game) was particularly hotblooded in his screams when being knocked down or attacking.
** Guy's name can be translated as[[MeaningfulName "Triumphant King Lion."]]
** Even in ''Anime/GaoGaiGar'', Guy's arguably just the crown prince of hot-blooded shouting. The real crown goes to Koutarou Taiga, GGG chief.
** Even the [=AIs=] for the other robots in the series tend to be pretty hot-blooded, usually in the "red" half of the RedOniBlueOni pairings. Although the combined Forms of said pairings are always hot-blooded. Also Goldymarg, an AI so hot-blooded it leads you to wonder if they programmed him in ALL CAPS.
*** Canonically, his Super AI was based on [[HardGay Geki]] [[LargeHam Hyuuma]] because they didn't have time to raise it.
**** "LET'S BREAK STUFF!" Famously yelled right before [[spoiler: he, now in the form of the Goldion Crusher, is used to '''''DESTROY THE SUN!!''''' (or rather, a false sun that was also an alien superweapon designed to annihilate the universe...but you get the point.)]]
* ''Anime/{{Patlabor}}'': The second-in-command mechanic [[TheDanza Shigeo Shiba]], and {{Expy}} from ''Manga/UruseiYatsura'' character Megane, is so hot-blooded that it interferes with his work. He takes ''great'' pains to take care of the Labors. And you better does not disrupts his job, or else...
* ''Franchise/{{Gundam}}'':
** ''Anime/MobileFighterGGundam'' does this to the point where it's arguably a parody. All of the main pilots are HotBlooded including George De Sand, and he's the stereotypical French gentleman outside his Super Robot. Whenever Rain Mikamura suits up she becomes a HotBlooded pilot, and she's the technician! In fact this series is so HotBlooded that Fuunsaiki, Master Asia's ''horse'', is HotBlooded. Just look at its suit up sequence.
*** Main character [[http://www.youtube.com/watch?v=HhwdPdtQs94=watch_response Domon Kasshu is the reigning king of this.]] ([[GurrenLagann Kamina]] and [[MartianSuccessorNadesico Gai Daigouji]] deposed him temporarily, and would have kept the position [[spoiler:[[TooCoolToLive if they had lived longer]]]]). He invokes the [[SoBadItsGood so hotblooded it's not corny]] rule with such ferocity that he takes it far beyond SoBadItsGood straight to completely awful and then rockets straight ''back'' up to ''[[CrowningMomentOfAwesome fucking awesome]]'' when he uses the full power of his "Shining Finger" attack. The last episode tops it with a RefugeInAudacity HotBlooded ThePowerOfLove attack. Since that would be too long a quote, let's just have a [[http://www.youtube.com/watch?v=0HZZzJBgYkE video of that scene]] and use a Shining Finger sword Quote:
---->'''Domon''': This hand of mine glows with an awesome power! Its burning grip tells me to defeat you! Take this! My love, my anger, and '''all of my sorrow!''' SHINING FINGER SWORD!
**** It's also treated somewhat more realistically, since his HotBlooded self is one of his biggest character flaws: the fact that he is constantly acting on his over-the-top emotions makes it very easy to [[UnwittingPawn manipulate him]] and lure him into traps... and very often, he [[SpannerInTheWorks ends up tearing through these traps]] [[TheDeterminator out of pure hot blood and willpower]].
*** Domon's GenderFlipped {{Expy}} [[Anime/CodeGeass Kallen Kouzuki]] seems to have taken after Domon himself to quite a degree (being a HotBlooded {{Determinator}} AcePilot who fights for justice, in a RealRobot show very much on the Cynical side of the Scale), proving that you don't have to be male in order to be GAR.
*** Many characters voiced by Creator/TomokazuSeki, most notable is probably [[Anime/MobileFighterGGundam Domon]] and maybe [[MartianSuccessorNadesico Gai]]. He's probably voiced more Hot Blooded characters than almost any other voice actor. Only problem is, he's voiced so many characters and with such a wide range of personalities that it's impossible to associate him with just the Hot Blooded ones.
** Graham Aker of ''{{Gundam 00}}'' does a lot of yelling and screaming for a RealRobot pilot, as well as some of the others in his squad. Thankfully, though, he's one of those characters who is hot-blooded AND has the experience, competence and sheer awesomeness to back it up. Some of his burning moments include screaming fallen comrades' names and vowing revenge, and in one instance, he sorties ''alone'' to fight a Gundam attack, and yells something about surpassing the Asura while slicing off the Gundam's arm (the first time a 'regular' mobile suit did harm to a Gundam in that series). Did we mention that he has no fear of having his body turned into pulp by G-Forces? Yes, Graham is hot-blooded AND awesome.
*** "'''HOOOOWARD MAAAAASON'''"!
*** And "GUNDAM!!!!!! I LOVE YOU!!!!!"
*** The aforementioned take-off to singelhandedly fight three Gundams on his own is accompanied by a nearly trope naming worthy 'I shall overcome reasoning with my recklessness!!!!' [[CrowningMomentOfAwesome He does]].
*** Patrick Colasour, anyone?
** Garrod Ran of ''[[Anime/AfterWarGundamX Gundam X]]'' shines this trope. What he lacks in experience he makes up for with sheer adaptability and Hot Blood.
*** Take for example whenever he uses the [[WaveMotionGun Satellite Cannon]], it is always accompanied by him [[CallingYourAttacks roaring for it to fire]].
-->"Satellite Cannon! FIIIIIIIIIIIREEEEEEEEEEEE!!!"
** From ''[[Anime/MobileSuitGundamSeed Gundam SEED]]'', we have Yzak Joule. In the [[GundamSeedDestiny sequel]], he is a bit less so, due to being more experienced, but [[TheBerserker Shinn]] [[ScreamingWarrior Asuka]] more than makes up for it. Shinn could be seen as a {{Deconstruction}}, seeing as he's [[LeeroyJenkins much less effective in combat]] when angry than [[CombatPragmatist when he's calm]].)
** ''Anime/GundamBuildFighters'' has Yuuki Tatsuya, who becomes even more hotblooded in his persona of Meijin Kawaguchi III. The cake is taken by Mr. Ral and Master Chinan in the final episode.
** ''Anime/GundamBuildFightersTry'' brings us Domon Kasshu {{Expy}} Sekai Kamiki. His gunpla, the Build Burning Gundam, even generates a halo of flames just through his sheer hot bloodedness.
*** [[spoiler: Sorry, did we say "expy?" Turns out we meant to say ''student''.]]
* Hot blood (or the use of PsychoSerum) ''[[JustifiedTrope powers]]'' the [[AppliedPhlebotinum Lambda Driver]] in ''LightNovel/FullMetalPanic!'' Pilots who can be relied upon to use it without fail -- mainly the villains -- often have this kind of attitude.
** Sousuke doesn't normally do this trope (being an absolute [[TheStoic stoic]] most of the time), but he does have one brief, distilled moment in ''Anime/FullMetalPanicFumoffu'' of HotBlooded-ness for the sake of a [[http://www.youtube.com/watch?v=LQ-_wi40_kY pre-rugby match Rousing Speech]] (starting at 5:35), at which point he might as well change his name to Domon Kasshu ([[HeyItsThatVoice Same voice actor again, by the way]]).
--->'''Sousuke:''' DO WE LOVE OUR HIGH SCHOOL!? '''DO WE LOVE OUR RUGBY CLUB!?!?''' THEN LET'S '''''GO'''''!
** Hey Hey, there's Issei Tsubaki. He has the [[MartialArtsHeadband headband]] too.
* Gai Daigouji of ''Manga/MartianSuccessorNadesico''. [[WrongGenreSavvy Poor bastard seemed to think]] he was in a SuperRobot show...
** That show being ''Gekiganger 3'', whose little-seen full title actually includes the term "nekketsu", as does the title of the ShortAnimeMovie, and a few of the special move names (Nekketsu-giri, the "Hot-blood Slash")... But surprisingly, it doesn't go nearly as far as some of the real examples.
* ''Manga/MagicKnightRayearth'' has this in ''spades''.
** Don't let Hikaru's go-lucky personality fool you. That girl will set you on fire if you hurt her precious friends or even people she barely just met...
** Umi seems to fit the trope rather well too...even though she's supposedly the ''Water'' Knight [[spoiler: of Selece]]
** Lafarga is naturally hot-blooded from moment one of his appearance but surprisingly enough even ''[[TallDarkAndHandsome Lantis]]'' who seems as mild-mannered and composed as they get will kick your ass and hand it to you if you challenge him [[spoiler:or even remotely threaten [[LoveInterests Hikaru]]]]
** Among the non-Cephireans, Princess Tata of Chizeta is hotblooded to the max. No wonder she and [[spoiler: Umi]] end up fighting more than once.
* Asuka from ''Anime/NeonGenesisEvangelion'' (she is a GenderFlipped {{Expy}} from ''[[Anime/GreatMazinger Tetsuya Tsurugi]]'', so she is also hot-tempered, arrogant, impatient and hard to deal with due to childhood trauma and confidence issues) and Mari from ''Anime/RebuildOfEvangelion'' (an AxCrazy BloodKnight who is not quite ''sane'').
* Tsubaki Sadamitsu from the little-known manga/anime ''Hakaima Sadamitsu'' eats, drinks and breathes this trope. In fact, the entire anime is an over-the-top AffectionateParody of HotBlooded {{Mecha Show}}s.
* Daiya from ''Anime/GaikingLegendOfDaikuMaryu'' broke the record for youngest hotblooded mecha pilot at ''13'' years old. This was the kid who lifts '''CITIES''' with his hotbloodedness.
* Nekki Basara from ''Anime/{{Macross 7}}'' is SuperRobot-levels of HotBlood channeled into a singer.
** His ''[[MemeticMutation daughter]]'' Sheryl from ''MacrossFrontier'' while normally an {{Ojou}}, becomes a hot blooded {{Determinator}} when it comes to her singing.
*** Both can be said to be deconstructions of this trope though. Basara can be plain annoying at times much to the annoyance of the rest of his bandmates. Shery, while trying to be a determinator and fly a [[TransformingMecha Valkyrie]] out of a battle fails miserably.
** Ozma Lee from ''Macross Frontier'' is also pretty hot blooded, kinda expected as he's a fan of Basara and Fire Bomber.
*** His CrowningMomentOfAwesome comes when, faced with an opponent who has developed immunity to all his regular attacks, he performs a BigDamnHeroes to save the [[CoolShip Macross Quarter]], then pulls out his mech's knife and proceeds to kick ass while declaring that he will fight with everything, down to his fists, teeth and nails, just to protect his sister as well as the woman that he has come to love, because if he could not, then he wouldn't be a man, all while badly injured. To top it off, Fire Bomber's ''Try Again'' plays during [[http://www.youtube.com/watch?v=w_-3dqGckro#t=1m25s this scene]].
** Bobby Margot also from ''Macross Frontier'' is, in addition to sporting an ''[[AfroAsskicker afro]]'', being a world class make-up artist, a BridgeBunny and HoYay, one of the most damned hot blooded characters in the show when he [[http://www.youtube.com/watch?v=yxXCV4DN3fU#t=2m pilots the Macross Quarter's battle mode]]. He's known as [[FanNickname GARby]] for a very good reason.
* Noriko Takaya from ''Anime/{{Gunbuster}}'', who may have been one of the first true examples of a female hot blooded protagonist in giant robot history, and still remains one of the best. How hot blooded is she? Let's just say she's got a SpearCounterpart in none other than [[TengenToppaGurrenLagann Simon The Digger]]!
** For 4 episodes, Noriko was very insecure and negative about her role as a savior of mankind... and then she finally piloted the Gunbuster at the end of the fourth episode, kicking that lack of confidence to the curb. Then episode 5 comes, which includes the four most action-packed minutes in SuperRobot anime history, with BILLIONS of enemies obliterated by Noriko's onslaught of awesome.
** Lampshaded in the VideoGame/SuperRobotWars games, where one scene has Noriko learning how to scream in Hotblooded fasion by none other than [[Manga/GetterRobo Ryoma Nagare.]]
* ''Anime/DieBuster'' also has its fair share of hot blooded characters, with Nono and Lal'C being the most passionate of the bunch. It is a great advantage, because the Buster Machines from this era are {{Empathic Weapon}}s that can create powerful physics-defying effects when influenced by its pilot will.
* ''Anime/ShinkonGattaiGodannar'' is a SuperRobot show, so most male protagonists are naturally Hot Blooded. [[spoiler: It also makes them vulnerable to TheVirus, leaving them with a dilemma: Hold back and risk being defeated by the MonsterOfTheWeek, or go all out and risk turning into one yourself?]]
* Adeu of ''Anime/LordOfLordsRyuKnight''.
** Lamune and Lamunedo from ''[[Anime/NGKnightLamune40 NG Knight Lamune & 40]]'' and ''[[Anime/NGKnightLamune40 VS Knight Lamune & 40 Fire]]''
* Duck Team from ''Anime/GirlsUndPanzer''. Their Tank is the [[TheAllegedCar nigh-useless]] [[http://en.wikipedia.org/wiki/Type_89_I-Go Japanese Type 89 I-Go]]. In spite of this, they run on pure HotBlooded '''[[{{Determinator}} GUTS!!]]'''. They won't flee. They won't stop. Should they retreat, it ''will'' be to draw you to a trap, and they'll do it firing all the way. And they are critical to every victory.
* ''[[Anime/VisionOfEscaflowne Escaflowne's]]'' Van Fanel seems a little too quiet for this trope at first (despite being voiced by Creator/TomokazuSeki), but then you put the boy in a mech and throw him into battle [[http://static.tvtropes.org/pmwiki/pub/images/crazybastard.jpg and]]...''Yeah''.
