City of Heroes is a massively multiplayer online role-playing game based on the superhero comic book genre, developed by Cryptic Studios and published by NCsoft. The game was launched in North America on April 27, 2004 and in Europe on February 4, 2005. In the game, players create super-powered player characters that can team up with others to complete missions and fight criminals belonging to various gangs and organizations in the fictional Paragon City. The game allowed players to customize their superhero into whatever color of spandex they desired... which allows for some good butt shots. Here are just a few below.
