Cobalt lived a normal life, got a girlfriend, a good job, his life was perfect, but then he was cursed with the power to change into a snake. His snake side of him took control and killed his girlfriend just as he was having a date with her. Red, Cobalt calls his snake side, killed some more people before running off into a forest. There Cobalt took back control over his body and now hides in said forest. He fears being around other people because he doesn't want to hurt them so he often seems mean and rude. Other wild snakes can sense Cobalt snake side so they often stick around him. To the snakes Cobalt is their king.
This is the very same Cobalt from Domore Magic High School, just before he attended that school. And please don't try to hook up with him because that's not happening. He's traumatized that he killed his girlfriend. Cobalt is my original character and I do use him for many things.
