Doc

The Omegan affectionately known as "Doc" hails from Aello, the same world as Harpis and Demonia. Doc was a zelous scientist who felt that his brain held more potential than his mind of flesh could contain. His solution was to to employ computer-based intelligence to amplify his own biological brain power. His colleagues warned that Doc would be sacrificing his humanity but he would not be deterred. His mind was transferred into a cybernetic head, which was then attached to his body — and Doc was ecstatic! (Omega Men #19)

Doc has consistently been a positive beacon among the Omega Men since joining them. (#3) Being half machine, half flesh, he is ideally suited to solve problems of both kinds.

Killed by a Durlan in Adam Strange #4 (2005), but appeared alive again in Omega Men v.2 #1.

Doc puts Superman to sleep with his "biopathy."
