Neurotic, manic scientist, maybe not specifically responsible for Roger and Steve's origins, but sometimes they are his assistants. "knife fight" and "the machine" by lemon demon are both about him. Pretty much cant be stopped once he decides something is his Destiny, nothing for good or evil, it just seems really important at the time, like a super villain. This guy specializes in chemistry and engineering, but he's really good at applying that to biology, and if he can convince a mystical being to assist, alchemy. The alternate face shapes and noses off to the side are all "canon" and his face periodically shifts between them due to. Sci-fi contrivances. Possibly a side effect of his own doing. Almost NOTHING is intentional. While I don't think he would experiment on unwilling subjects, he has dubious moral standards as even if his projects were to go perfectly as planned, they would have terrible complications everyone told him about but which he assumes won't happen, cos it just seems too cool and important to have consequences!
