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.
- Tahu from BIONICLE, with the Personality Powers to boot.
