Connor of Assassin's Creed III is young, passionate, and something of a Wide-Eyed Idealist. He views the world through a lens where injustice must not be tolerated, at any cost, and so has a tendency to charge headlong into situations without thinking. This gets him in a lot of trouble.
Asura from Asura's Wrath is so hot blooded that he can punch and destroy a finger from A PLANET SIZED BUDDHA, all while giving out guttural roars and screams. And destroys it. English voice Actor Liam O'Brien makes him sound even MORE Hot-Blooded.
Made even more impressive by the fact that, while O'Brien plays badasses all the time, they tend to be the cool, calm, and collected type. Who knew that even the God Of All Voice Actors was capable of playing against type so well?
Everyone in Bangai-O Spirits, the lighthearted, plot-free DS spinoff, in different ways. Ruri is more enthusiastic, especially when the time comes to shout "Bangai-O GO!", while Masato thinks the whole thing is stupid. On the other hand, he's very confident, reckless, always ready to get to the mission already.
Gorath from Betrayal at Krondor. He'll get it done. It doesn't matter what he has to go through or sacrifice to do it.
"QUICKER THAN THE WIND AND AS STILL AS THE FOREST! HOTTER THAN FLAMES AND MORE MAGNIFICANT THAN A MOUNTAIN!"
When one of Bang's specials, Fuurinkazan, which the above is taken from, is unleashed, the background music is replaced with his very own theme song performed by — of all people — JAM PROJECT. (Or more specifically, Hironobu Kageyama.)
Also, when using his astral finish, his burning passion ends up burning his clothes off.
Garlot of Blaze Union; it seems to be a requirement for a young freedom fighter such as himself to be passionate and reckless to a fault. Three years later, he's still like this, charging into lots of things scythe-first. Interestingly enough, his blood also happens to be hot as well. More apparent once he's changed his name to Gulcasa, he's physically more demon than human, as a true descendant of the demon dragon Brongaa. Burning blood, superhuman strength, and (while exerting his full power) an actual aura of fire happen to be side effects.
The new Willpower power set in City of Heroes allows for characters that have no super reflexes or resistance, but can remain up and fighting with the super-powered through sheer force of will. If that's not Hot Blooded, I don't know what is.
Alex, the protagonist of The Colour Tuesday, is a hotheaded, brash delinquent whose burning drive, implacable idealism and willingness to keep going where others give up is what drives the story at times, even as it makes her rather stubborn (in an Only Sane Woman-ish sort of way) and at times a little obnoxious.
Bella: "Also, you have no tact."
Jin Saotome from Cyberbots. Especially in his Marvel vs. Capcom 2 incarnation, in which most of his kicks and punches are on fire! Even better, you can mash some buttons when taunting to make him wipe his towel on his back faster and faster until he's practically screaming his lungs out and on fire.
Asuma Shidou from Daemon Bride fights with his Power Fist burning on fire and is always yelling with full of hot blood when attacking.
Laharl and Flonne from Disgaea, and Adell and Axel from Disgaea 2. And then there's Captain Gordon, Defender of Earth!, who is guaranteed to give it his exclamation-point abusing all no matter what it is. Including picnicking.
Disgaea 3 gives us Champloo-sensei, the most badass, Hot-BloodedHome Ec teacher you will ever find.
Dragon Quest V: Parry, the Hero's son and real Chosen Hero is passionate, bold and reckless. Amusingly, if Debora is his mother, it's implied he gets it from her.
In Dragon Quest Monsters, the monsters' ideal personality (which affects their AI) is Hotblood.
It's easier to mention which characters are NOT hot blooded in Koei'sWarriorsseries. Warriors Orochi in particular has so much hot blood (being a fusion of both Dynasty and Samurai), it's amazing the games' boxes didn't melt off the shelves.
Another Koei series that should by all rights have melted a hole through store shelves is Dynasty Warriors: Gundam. The list of Hot Blooded crazies over in the Gundam list from the Mecha Anime and Manga section is a good starting point. A short list of playable pilots who bury the needle, in regards to their personalities: Domon Kasshu, Graham Aker (as Mister Bushido), Garrod Ran, Angelo Sauper, Kamille Bidan, Judau Ashta, Dozle Zabi, Gym Ghingham, Cagalli Yula Atha, Yzak Joule, Shinn Asuka, Setsuna F. Seiei, and the Knight Gundam (yes, the Gundam itself).
Though it's a bit more subdued than most examples, the Nords of The Elder Scrolls V: Skyrim definitely have shades of this, especially the old-fashioned Stormcloaks, who will walk over whatever rules or enemies get in their way in order to fulfill their understanding of right while charging you screaming and with a huge battleaxe.
Kim Kaphwan and his son Kim Jae Hoon from the Fatal Fury series, as well as Joe Higashi, who seems to have an exclamation point at the end of everything he says and the bandana-wearing commando Ralf Jones, also of Ikari Warriors, The King of Fighters, and Metal Slug fame. When he gets in motion (which is practically all the time), people get beat down. Sometimes explosively.
Zell in Final Fantasy VIII, and he never sits still. Put him anywhere near Genki Girl Selphie and you'll be wishing for Ritalin.
Zack of Final Fantasy VII is a prime example of this trope, depressingly.
Which is highlighted even further by contrast against the dark and dreary nature of the world the game takes place in, and the general angst of other characters in the game world (especially in the expanded games and movie).
Quite a few characters in Fire Emblem: Awakening sound like this in their critical quotes, some more than others but especially the males, yet no one can deny that the grandmaster of all things Hot Blooded in the entire damn franchise is Owain, aka HE WHOSE SWORD HAND THIRSTS FOR BLOOD AND BATTLE, AND WHOSE NAME SHALL BE FOREVER REMEMBERED IN THE SAGAS!
On the Nohr side, Owain's expy Odin is basically what Owain would be like were he a Black Mage instead of a Swordsman. Even his personal skill is based on his hot blood, greatly increasing his Critical Hit ratio if he's given a tome that fulfills some special criteria. Ultimately justified, since Odin is Owain, who alongside Laslow/Inigo and Selena/Severa has come to to Nohr...
On the Hoshido side, there's Prince Ryoma, his retainer Saizo, Ryoma's son Shiro, and the swordsman Hinata. All of them are passionate, emotional, and very powerful fighters on top of that.
Fire Emblem Echoes: Shadows of Valentia has Forsyth who's very, very passionate about pretty much everything he does. It's also the main reason he finds his partner and best friend Python so baffling.
Goemon is a hotblooded man of Edo (despite his looks), who is always itching to beat the snot out of villains with his trusty pipe when they cause trouble. When the Japanese title of his series has "Ganbare" ("Do your best/Hang in there") in it, it's to be expected.
In Gems of War, Sapphira, the local quest-giver, is rather impulsive and reckless; after she was attacked by religious warriors, her response was to immediately attack the nearest town and burn down its temple, ignoring both short-term outnumbered-ness and long-term consequences. (As her card's text says: "Not all vampires are evil, some are just crazy.")
God of War's main protagonist Kratos is shouting ALL THE TIME. Plus the way he fights is just raw brutality (often ending with him ripping his target to literal shreds with his bare hands).
Kid Icarus: Uprising: Pit is a passionate and energetic angel who is easily agitated and overexcited — at one point, he even does a really over-the-top In the Name of the Moon speech before battling Pandora.
Kirby brings us the hot-blooded priestess Flamberge, a Fiery Redhead who is described as raining fiery vengeance upon those who oppose her, especially if they happen to mess with fellow Mage-Sister Francisca. She loves to convey her emotions by shouting, and fittingly enough, tends to get pissed off very easily.
Bowser in Mario & Luigi: Bowser's Inside Story is this when he's not a Butt-Monkey. The game mixes his normal bullheaded determination with outright heroic courage, including some passionate Victory Poses that include chest pounding for pulling off successful special attacks, pumping his fist for victory and a Badass Armfold for when he's about to pull off a Finishing Move on the Final Boss. His lines are also like this, especially his Shut Up, Hannibal! moments.
Commander Shepard (both Paragon and Renegade) of Mass Effect, to such a degree that Taligets a line about how fun it is to watch him/her yell. Also Zaeed Massani, all the way. He survives being shot in the head at point-blank range SOLELY because he wanted to kill the guy who shot him.
Nearly all of the fire bosses in the Mega Man Zero and ZX series are pretty Hot-Blooded, including the fire master, Fefnir. Oddly, near the top of the Hot-Blooded ranking for all six games is an ice boss, Fenri Lunedge from Zero 4. His attitude to Zero, and more importantly his voice clips, put him probably right under Fefnir himself.
Another Hot-Blooded ice boss is Chilldre Inarrabita, to a lesser extent than Fenri Lunaedge. Although he has a partial excuse in being a deliberately juvanille character (Chilldre = child[ren] + chill).
Metal Gear. Metal Gear? There's Snake, Liquid, all the bosses (especially Raging Raven and Fury), even Otacon gets his moments. Usually paired with large amounts of Say My Name.
Osu! Tatakae! Ouendan: If you're in trouble... if there's not enough hotbloodedness... maybe you need to call... OUENDAAAAAN!
Or... e... b... a... e.. b.. a.. e. b. a. e.b.a. E.B.A. EBA! EBA! EBA! EBA! ARE YOU READY? YEAH!
The sequel to Ouendan is titled Moero! Nekketsu Rhythm Damashii which translates to "Burn! Hot-Blooded Rhythm Soul!"
"Hot-blooded manly passion" is a major aesthetic element of Japanese cheerleading in real life, though obviously not to the EXTREMES — like stopping a meteor or reviving a burning-out sun - that this series in particular takes it.
Hop from Pokémon Sword and Shield is so eager to become a Pokémon Trainer that he trains hard every day in hopes that he can become the new champion of the Galar region, and often jumps at the opportunity for a friendly battle to see how much he's grown as a trainer himself. Whenever he Dynamaxes his Pokémon, he throws his Poké Balls with so much force that he nearly falls over in the process of doing so.
In Puyo Puyo!! Quest, Atari has such a passion for her job as a spacetime detective that it tends to get in the way of her actually executing her job properly, as she jumps head-first into everything.
Batsu Ichimonji from Rival Schools is described in the manual as the "Hot-Blooded Exchange Student". Furthermore, his Super Mode form in Project Justice is called "Burning Batsu" and all his special and super moves in that form set the opponent on fire!
Nekketsu Kouha Kunio-kun — He has "Hot Blooded" right there in his series title! His whole high school is named "Nekketsu". That's one bad-ass high school.
And Kunio/Alex himself is the hero of the school, being summoned whenever a crisis emerges or a sports challenge comes up. His girlfriend can kick ass when she feels like it. Kunio/Alex isn't as known and respected as he should be, in video games...
In Ryzom, player-characters can get pretty loud when they engage in melee combat with an enemy, even if said enemy is something that the character would easily kill in one hit. As far as the lore goes, the Fyros as a race are this, being the Proud Warrior Race and enjoying doing everything with gusto and enthusiasm (and also enjoying the occasional fight).
In the Sakura Wars series, you can choose what Ogami's (and Shinjiro's) responses to various questions/circumstances are. Usually, the most proactive one will have a frame of Ogami/Shinjiro shouting with flames in the background. The hotblooded choice isn't always the right choice, but more often than not it is.
The more you select Ogami's hotblooded answers in Sakura Wars, the better you're probably doing. SpiritArmor's Let's Play of it parodies this to great effect.
Red from Solatorobo. Elh outright calls him "hot-headed", and he only solves one of the three riddles for the Flute, settling the first two with violence. Frequently charges in without thinking, and says some pretty cheesy things with a straight face. It helps that he's voiced by Tetsuya Kakihara.
Sonic and Knuckles from Sonic the Hedgehog are pretty good examples, but in different ways. Sonic is cheeky and quick to taunt his opponents, as well as being a rather Boisterous Bruiser when in the heat of battle. Knuckles has quite the Hair-Trigger Temper and always quick to solve things with violence. The two of them get along rather well surprisingly, most of the time.
Wataru Hoshi from Star Trigon.
"With names like Hoshi and Big Bang, we're DESTINED TO BE IN OUTER SPACE!!!!".
Street Fighter's Dan Hibiki. "DOUSHITA DOUSHITA?!" "OYAJIIIIIIIII!!!!" It's probably no coincidence that Dan's seiyuu in 4 also voices Hayato Saionji in Ouendan 2, mentioned above.
Perhaps the strongest force in the Super Robot Wars series, rivaled only by the Ideon Gun. In fact, one of the most useful special skills in the series is the "Valor" skill (Doubles the strength of your next attack), which in the original Japanese was called, you guessed it, "Nekketsu" (Hot Blood). In fact, damn near every character in the Original Generation games uses it, even the shy ones.
Special mention to the normally stoic Kyosuke Nanbu; once he performs the maneuver he will shout out the attack name so hot-bloodedly. It is good to note that his seiyuu did break two microphones on separate occasions. See examples from one of the games here and here for the anime version
The Inspectors, makes this a Justified Trope: when the attack is ready to launch, the control panel flashes over with the verbal command to unleash the attack: "SHOUT NOW!!"
From the same game, Katina Tarask. With Attacker, Revenge (both of which increase her attack/retaliation damage once her Will level exceeds 130 - see above) and Prevail (which makes her fight better — dealing more damage, taking less, and evading more — as her mech sustains more and more damage) and the aforementioned Valor skill, she can deal out some serious hurt, usually yelling all the time (although not as much as Sanger), even when attacking carriers. "Reckless" barely describes her.
"I SAID, GET OUT OF MY WAY!!!"
Super Robot Wars also quantifies this in the form of the "Will" stat. It starts each battle at 100 and can rise to 150 based on the tides of battle. It affects combat ability a quite a lot (each point of Will is like having your Attack, Defense, Accuracy, and Evasiveness all boost by one percent of their base amount), and certain weapons and effects can only be used over a certain Will value. Certain events (like some GaoGaiGar events) will boost this up to 200 or even 250, and that's before any spirit commands.
However, the crowning glory of the Super Robot Wars series for Hot Blooded characters is Sanger Zonvolt. The series' self-styled (but highly deserving of it) Sword That Cleaves Evil, Sanger takes on all comers and owns them all. Always wielding some form of his Colossal Blade, a gigantic mecha sword that is sometimes THREE TIMES AS LARGE as his mecha, his sword is one that can cut through anything. Also armed with his many idioms and sayings, which he yells right before slicing his poor enemy in half.
"I AM SANGER ZONVOLT! THE SWORD THAT CLEAVES EVIL!"
Sanger's Heterosexual Life-Partner Rätsel Feinschmecker might initially look like a Blue Oni to Sanger's Red, but then things like this happen and prove that he's only a blue by virtue of Sanger being even more hot blooded.
Really, Super Robot Wars is absolutely loaded with characters like these. In addition to Sanger and Katina, there's also Touma Kanou (who got so hot blooded at one point that he lost control and went on a rampage), and Folka and Fernando Albark, the Grand Masters of martial arts. Though we haven't really met him yet, presumably Folka's Expy Aledy Naash will also be like this when Endless Frontier EXCEED comes out.
Even without the absolute awesomeness of Takuma Terashima's voice, Fighter Roar proved how hotblooded he was by taking out Humongous MechaON FOOT... and then we get him in the Compatible Kaiser and things just go nuts. Then it gets upgraded to the G-Compatible Kaiser, and THIShappens.
Ryusei's character description says he's an "EXTREMELY hot blooded young man". He proves it in spades.
Even characters from other series that are featured in Super Robot Wars are instantly turned into Hot Blooded badasses. Notable mention goes to Neon Genesis Evangelion's Shinji in the Alpha series, where he went from a spineless wimp to an asskicking god.
Like Bullet says "Let's go Hot Blooded LEVEL MAX ! UMASUGI WAAAAAAAAAAAAAVE !"
Tales of Phantasia has Cless begin the trend, pretty hot-blooded when his home gets destroyed, his parents get killed and his best friend's little sister, too. He will follow you to the end of the earth and through time to stop you... DHAOS!!
Tales of Destiny: Stahn Aileron. The boy can be hot-blooded when commanding his allies to flee. His battle cry in Satsugeki Bukouken/Final Fury is ORENENENENENENENENENENE!!!!!! Hot Blood, to the max.
Lloyd of Tales of Symphonia is very hot-blooded when provoked or his friends are threatened. He declares war on the Desians out of anger and outright said he desired to kill all of them. He also had little quarrels about beating an angel to death after he took the soul of his childhood friend, kept attacking a person who could easily own the entire party out of irritation. Granted, he cools down as the game goes on and he is nearly a stoic in the sequel, but he can still fly off the handle if he is angry enough.
Tytree Crowe "SISTER! ! !" (plus points for being voiced by Kappei Yamaguchi)
Team Fortress 2 features a cast comprised of pork products, but among them the most passionate has to be the Soldier, hands down. A complete psychopath driven by Patriotic Fervor and an understanding of reality so that is so absurd it defies explanation or logic, he also manages to demonstrate a driving force of will that even his larger comrade the Heavy cannot muster. Every other word out of his mouth exits at the top of his lungs and his tactics can often be described as "I will point this rocket launcher at my feet and launch myself skyward to catch the enemy off guard!" Even when losing, he doesn't seem to understand concepts like despair or surrender, and instead berates his team for not trying harder. A domination line to the enemy Pyro lampshades:
Soldier: You cannot burn me. I am already ablaze with passion for war!
From Total Overdose, the protagonist Ram, aka 'El Gringo Loco', is more hotblooded than his father. A great deal of accurate puns follow from the name 'Ram'.
Undyne of the Royal Guard from Undertale, who does everything with maximum passion. She will randomly suplex a boulder in the middle of fights just because she can. This extends to her social interactions (making her a Large Ham), and even her theme, Spear of Justice, seems full of energy.
By extension, Papyrus is also this after hanging around Undyne for so long, except he mixes it with his enormous Cloud Cuckoolander tendencies, which leads to him being being very enthusiastic about his weird ideas.
, but the characters who are already Hot-Blooded turn that sucker up to twenty-two
