Beware what lurks in the shadows

Dr. Wily's first child, raised in the height of his rage and madness. Though his father has mellowed out, the damage has been done and the son he raised has become a ruthless, uncaring person who feels little for any save his sister and his Navi.

A replacement for the original Dr. Regal, following an alternate storyline. Don't expect much accurate Battle Network canon here.
