DC OverPower is the 4th expansion and also the 2nd base set of the OverPower CCG, based on DC Comics characters. It is published by Fleer/Skybox in 1996. This set consists of 353 cards.
This expansion introduced the Intellect Power type. It also introduced the allies, a new type of universe card, as well as Hero and Villain codes, a concept which was not used extensively in the game and never adopted by any Marvel OverPower expansion.
DC OverPower was also dubbed Batman/Superman OverPower since all its characters were from these two heroes' storylines.
