Percy van Norton took a serum which made him into a "perfect human," with a range of physical abilities.

But although he started out fighting crime, something went wrong, and he turned bad, ending up fighting alongside Volton, Spider Queen, the Human Meteor, and Doctor Nemesis, as a member of the Battle-Axis, against the Invaders. At the end of the battle O'Dowd, along with the other Battle-Axis members, was defeated and captured.

van Norton's current status and post-war history are unknown.

Note: Strongman first appeared in Crash Comics #2 (May 1940). However, as a Marvel character, he is a retcon addition, not having appeared in a Timely book.
