Shadow

(Assume either in Marvel or DC universe, do whatever). Shadow is a built, pure black figure with white eyes that can move in and out of shadows. During the night and in dark, he is strongest, with super strength, speed, durability. In light and day, he is weakened. Shadow has a human form named Aaron Stephens, a normal guy with a good face and figure. Shadow uses many weapons, but mainly a sickle or fists. Shadow has spent years working on gymnastics and fighting, honing his powers, and making himself a formidable opponent and good superhero. (This is my original character, inspired off of Noob Saibot from Mortal Kombat, I like to imagine he has similar physical strength and durability of around a videogame or comic book Spider-Man).
