They are burningly passionate about everything that they do. They give their all in absolutely everything, regardless of the task. They do not know how to be half-hearted or lackadaisical about anything they care about. These characters are Hot-Blooded.
Using the power of guts, determination, and badassery they throw themselves headfirst into the worst situations imaginable and come out on top through sheer force of will and often have a strong tendency to do impressive things. Even non hot-blooded characters or the nicest ones can occasionally have their own hot-blooded incidents; this is frequently their Moment of Awesome.
Beware if they go into an Unstoppable Rage or Tranquil Fury; someone's really managed to piss them off. Triple that for elemental or Personality Powers; they're likely Playing with Fire. Especially common in the Super Robot Genre. The hot-blooded person is usually, though not always, identifiable by a mane of scarlet hair and/or Hot-Blooded Sideburns. A common trait of The Ace and, to a lesser degree, the Boisterous Bruiser. This trait is a staple of Choleric characters in a Four-Temperament Ensemble.
Compare with the following:
- Audacity Earns Approval: Their willingness to take risks earns the support of others.
- Ax-Crazy, if the hot-blooded character is mentally deranged.
- Fiery Redhead, when the trope applies to redhead (often female) characters.
- Hair-Trigger Temper, when a character gets angered or irritated easily.
- Large Ham, which is about extreme expression, with or without extreme emotion.
- Genki Girl, which is about being excitable.
- Keet, which is the Spear Counterpart to Genki Girl.
- Macho Latino, when the trope concerns hypermasculine men of Hispanic origin.
- Rambunctious Italian, when the trope concerns Italians/people of Italian descent in particular.
Contrast The Ever-Calm, The Stoic, Mellow Fellow, and The Spock.
Not to be confused with My Blood Runs Hot, which is when a character has literal hot blood, though at least some of these characters may be metaphorically Hot-Blooded as well.

Other examples:
- As Leonardo paints it in The Last Supper, Peter doesn't react to Jesus's news with shock or confusion, but with visible anger, reaching across the table to speak with Jesus.
- In Happy Friends, Happy S. puts a lot of passion into a number of things he does, such as demolishing a skyscraper just to save a kitten.
- Dawn of a New Age: Oldport Blues:
- Jemimah is a naturally loud person who fills every room she's in with her overabundant enthusiasm. She's entirely dedicated to her dream of becoming a judoka, and gives her all to any situation.
- Luna is loud and proud, passionate and confrontative. She puts her all into everything she does, whether that's being a part of a punk gang, enjoying nerdy hobbies, or fighting against corrupt politics.
- Xandus at the beginning of Mall Fight 2 was quite passionate with being a daemon prince.
- Saede, Ti'Cira, and Satkia in The Gungan Council, for obvious reasons. It's a good idea not to mess with them.
- Dreamscape: Izane gets fired up real easily, despite being a bit on the moody side.
- Despite her bitchiness, Betty turns out to be this in battle. She is always bantering with her opponent and excitedly dishing out blows.
Betty: (after Melinda gets restrained) HELL YEAH! We got you, you arrogant son of a WITCH!
- Despite her bitchiness, Betty turns out to be this in battle. She is always bantering with her opponent and excitedly dishing out blows.
- DSBT InsaniT: Bill is always pumped up, energetic, and ready for a Rousing Speech.
- Indus of Epithet Erased certainly falls under this trope. He is passionate about everything, especially his epithet, BARRIER, which he yells frequently and includes in almost every sentence. He believes that he must put his heart into everything because that is the honorable thing to do, whether that be a posing contest or moving boxes.
- Helluva Boss:
- Blitzo is bombastic, fast-talking, and enthusiastic about any mission he’s given, having boundless amounts of stamina and not hesitating for a moment to snap at anyone who rubs him the wrong way for whatever reason.
- Millie is just as energetic as her boss and arguably even more easy to excite and rile up. She loves to battle whether it's competing in the Harvest Moon Festival or slashing her way through armies of targets as part of a hit she's been given.
- Yang Xiao Long of RWBY not only has a fiery temper, but she actually creates fire when she's sufficiently pissed off, as seen here
. Her temper is occasionally Deconstructed; she's very susceptible to Trash Talk and quickly gets frustrated when a fight doesn't go her way, and it led to Neopolitan defeating her easily and almost killing her. It also allowed her to be framed for breaking Mercury's leg: although Yang is a nice enough girl and was tricked into doing it via illusion, her foul temper made the scenario very believable to the crowds watching, leading to her arrest and disgrace. A later episode deconstructs this even further, with Yang losing an arm to Adam when he baits her into attacking recklessly by stabbing Blake. At the end of it all, she falls into a Heroic BSoD that she takes the entirety of Volume 4 to recover from.
- In X-Ray & Vav, X-Ray, compared to his real-life counterpart, Ray, is easily this. To the point where he does stupid (and destructive) stuff.
- The Call of Warr: Though he's not a Sociopathic Soldier, Prince's still very impulsive, temperamental, and prone to violence. He gets very antsy and impatient when Gravesite is "interrogating" the prisoner, and constantly attempts to kill them. Most of his lines are expressed loudly and angrily, and he seems to get upset at any minor provocation.
- Parodied in this sketch
. Translation:
- Tennyo from the Whateley Universe has the sort of temper that causes temperatures to rise - and Geiger counters to go Off the Scale. She has to wear a radiation meter, because she starts emitting hard radiation when she gets too angry... which isn't at all uncommon.
- WADDUP!! IT'S DASHIE! AND WELCOME TO MY TVTROPES PAGE!
- Echo Rose is boisterous, emotional, and filled with boundless energy. Even after having a breakdown, she bounces right back into being passionate and determined to live her life in Nettlebrook. Her videos are filled with emotion, and even her quick, humorous, stylistic editing is full of character and life.
- Fred Figglehorn is so Hot-Blooded, he probably has ADHD.
- Lydia in The Lizzie Bennet Diaries, who will remain known for this, her courage, her memes, and her gambits.
- Like the above, Linkara maintains a calm, collected and analytical demeanour, yet his catchphrase is "I AM A MAN!!!", followed by a punch. He got it from Superman: At Earth's End.
- Mahu: General Stanislaw Poniatowski fits this trope, being far more impulsive than other generals of the Commonwealth Republic.
- Musclebomber2021
was often like this with his Let's Plays.
- While The Nostalgia Critic is sometimes calm, logical, and would probably like to think of himself as usually sane, he's this in a nutshell when he gets upset or angry.
- OH WHAT THE-! Sir Ron Lion Heart isn't on this list yet?!
- He is now. And that is just ULTRA OMEGA FANTASTIC!! YEAH!!!
