Let's face it, some characters are pretty damn hot
. Other characters may have raging hot passion
. But in this trope's case, we find fictional creatures that are literally Hot-Blooded
(or anything that's close enough to blood
This type of being usually has an implication (or at least a possibility) of a temperature difference that's caused by metabolism-based weirdness. This makes some sense, as there are several organisms in Real Life
that have an average body temperature that's higher than the human average.
Characters that can play with fire
tend to exhibit this trope, along with many fire-related monsters like dragons, salamanders, and fire-related familiars
. Lava Beasts, fire elementals, and other creatures that actually made of some heat related substance are another trope altogether
They may be Wreathed in Flames
, or have Flaming Hair
as well. Contrast Chill of Undeath
Anime and Manga
- Shishio, the season 1 big bad of Rurouni Kenshin. He was shot in the head and lit on fire before being left for dead. The fire left him disfigured, and all of his sweat glands were destroyed. As such, he has incredibly high body temperature, which (apparently) grants him almost superhuman speed and strength. The downside is that he can only fight for a few minutes before the heat buildup kills him.
- The Pillar Men from JoJo's Bizarre Adventure have each mastered a type of fighting style called "Mode", where they freely transfigure their own bodies to emulate Elemental Powers. Esidisi's Mode is flame, which entails heating his blood to 500 degrees Celsius then extending his blood vessels from his body and injecting his blood into an opponent. The results are just as horrifying as they should be.
- What happens when you piss off someone upgraded with Extremis in Iron Man 3. (Volcanic Ghost Chili level)
- The Assblasters from Tremors The Series. As their name indicate, they fart fire to fly in a rocket-like manner.
- True Blood has its Werewolves.
Alcide: We run hot.
- In Farscape, Scarrans are extremely hot, and can project this heat as a weapon. Compare with Sebacceans, who are colder than humans and vulnerable to hot temperatures. Scorpius, being a hybrid of both races, needs cooling rods implanted in his head to survive.
- Technically Scorpius can survive without coolant, but will always be weak.
- In the Supernatural Season 4 finale, Sam Winchester was said to have reached body temperature of 150F (65C) when he was killing Lilith, courtesy of the demon blood he was using.
- Many Fire-typed Pokémon are described as having a flame-producing sac or other such organs in their bodies. Some Pokémon like Magcargo and Heatran literally have magma for blood.
- The Ax-Crazy bioweapon Alexia Ashford from Resident Evil: Code: Veronica's main method of attack is slinging her blood at her foes, which combusts on contact with the air. Another host of T-Veronica, Manuela Hidalgo shows these same powers, though she's not nearly as evil as Alexia. It can be assumed that the fire-based attacks of her father Javier's V-Complex form run on the same principal as well, as they spring from Veronica too.
- In PS238, Suzi has an internal body temperature which can melt lead, which appears to stem from her radioactive nature. Incidents where she loses her temper are explained as "gas leaks".
- Roza: The heroine's blood combusts when spilled.
- The salamander demons from Heart Core (Carval and Volaster Jarvoc) has explosive blood wich they use in order to make bombs.
- The whiptail lizard has an average body temperature at 106 Fahrenheit.
- The hotheaded naked ice borer, a cryptozoological animal invented for an April Fool's hoax.
- Canines in real life have normal body temperatures that are slightly higher than a human's, which may or may not have anything to do with werewolves usually having high body temperatures too.
- This is mostly true for most small warm-blooded animals. Mostly due to the Square/Cube Law.
