Abilities: Ability to project beams fire hot enough to melt through metal. Ability to project beams of ice at an absolute zero. Means of both freezing and burning something so that it is perpetually encased in ice and perpetually on fire at the same time.
Backstory: Originally little more than a humble janitor working in a quiet small town in Ohio. Celsia like all her family and neighbors worked at the nearby Positron Power Industries power plant which employed 70% of the towns population.
However while cleaning out the office trash one day and taking it to throw out, Celsia discovered a transcript of a phone call between the plant manager and the ceo of the company. Detailing how the plant was going to explode and thanks to the combined efforts of Aiden Roberts, Jason Fletcher, and Donald Dekirk, the plant would meltdown and the company would make billions on the insurance. So the manager needed to leave so he didn’t get caught in the disaster as well.
Celsia headed to town to notify the sheriff and share what she had discovered. But on the way there the nuclear power plant exploded, killing everyone in the town. Everyone except Celsia who somehow survived the explosion.Though forever changed, for she was now permanently frozen and on fire. With the power to project ever frozen ice and ever burning flames.
Swearing revenge on those who hurt everyone she knew and cared for, Celsia would dedicate herself to hunting down the nuclear cabal who caused those deaths and end their lives.
