How about Superman: Red Son? Superman grows up in 1950s USSR and quickly rises to leadership of the country, then takes over most of the world (save for the US) while liberally using lobotomies to maintain power. Nevertheless, he turns the world into a relative utopia, and continues to perform typical superheroic acts literally everywhere. His foil is Lex Luthor, a super-genius and manipulative bastard whose only goal is to bring Superman to ruin. (And then there's that question... those who have read it will know what this refers to.)
