A pyromancer has the ability to increase or decrease the temperature of both objects & air within 57,600 square feet. No matter what the object is the character can manipulate it as long as it's at or above 1 degree. 2,000degrees is the limit to how hot something can be heated to & 1 degree is lowest the character can decrease something. If you have seen X-men first class the scene where Shaw is able absorbs the grenade explosion is similar to what the character can also do.
Flaws:
- Can only be active for 12 hours each day at peak strength at noon.
- Needs a daily calorie intake of 7000 or risks spontaneous combustion.
- Can not produce any form heat if soaked in a standard pool of water.
- If soaked needs 9 hours for abilities to return.
- Can not exceed speeds greater than 35mph.
- After the sun sets cannot produce temperatures over 55 degrees.
- If taken 10,000 feet sea level begins to readily lose oxygen.
- Must be in a space that is the size of a locker room or larger to produce anything above 100 degrees.
- To manipulate another objects heat it must know its boiling point.
Lastly, if the character dies there is a chance that it explodes a creating an explosion similar to the fission bomb but on a smaller scale say a city buster but only if the character is about 40 or above.
All temperature used is measured in Kelvin. Honestly, this is what pyromancers in my world can do but the science behind it isn't really my expertise. If they existed in our world how dangerous would they be?
