prince namor would have kicked aquamans rear !
namor did do all sorts of crime/evil fighting on the surface of Earth, and even other planets and dimensions... for a time, he was member to a crime fighting team called 'The Defenders' with Dr. Strange, Valkrye, The Hulk. He was replaced at some point with NightHawk... but i think he came back again later... i dunno, i stopped buying the dang things when the price went over .35 cents. but i do still have a bunch of those old rags boxed up and stored.
