Crimson Knight

You are an average citizen. One day while walking through the city a meteor came crashing down, destroying everything in it's path. The impact caused powerful tremors and immense waves of radiation. Somehow you are the only survivor, but your body feels different. As you try to recollect yourself you hear a voice hovering above you. (Pick your powers and survive. As far as you know you are the only superpowered being on Earth.)
