Powers: A trained scientist, specializing in "body cell research."
Bio: A former college professor of Hank Pym's. Pym, as Goliath, seeks Anton out when he is stuck at a 10-foot height, looking for insight into a cure for his condition. In South America, Anton has been taken captive by the Keeper of the Flame in the hidden city of el Dorado, and is threatened with death as a spy. Goliath and the Avengers rescue him, but he is unable to help with the height problem, instead simply recommending that they consult with Henry Pym (obviously, he does not realize that Goliath is in fact Pym).
