Heat generation is the ability to emit greater-than-normal heat from the body.
- Mrs. Comey is the only character who has demonstrated this ability.
Not much is known about this ability as it has only had one demonstration. In it, Mrs. Comey placed her hand on an unplugged waffle iron and concentrated. Her hand super-heated and cooked the waffles to perfection.
On a list written by Edgar, Mrs. Comey is described as a "heat generator".
