He is an evil scientist known as red, who is bisexual, and hes more of a HUGE Anti-hero rather than actually evil, he had a childhood where his father wanted him to take over the family company, and kinda neglected him. The Rainbow friends (Blue, Green ((Green is blind)), orange and purple didn't like him, as red always had experiments to try and get them to follow his orders. But they are all he's got, and he does actually try and save them in situations where he did not cause the bad event.
