Its probably not worth talking about as ice powers are reserved, but I was thinking of a power set where you do fire and ice. Kind of. you would take heat from the surrounding area, air, objects... people and then store it in yourself to be released in heat/fire attacks later. that said i do have this distinct image in my head of using this to press a finger through a metal door like a lightsaber and cutting through it that way. Problem. While the fire would be dangerous the stealing all the heat in an area just kills everyone around the user and probably would make it to powerful/unwieldy for group scenarios.

Anyway off to think of something else as ice powers are still reserved.
