Champions developed into a general-purpose RPG, the HERO System, and is currently published as HERO System 5th Edition Revised. The book currently published as Champions is a guide to the super hero genre, with particular attention on how to run it using the HERO system.
Champions, in all of its editions, and the HERO system, use a point-buy (diceless) character creation system allowing the players to design the characters they imagine, unencumbered by classes. The effect based power system lets them create new powers based on effects. Characters are fully defined with skills, talents, and disadvantages.
