Champions is a superhero role playing game system. Affectionately referred to as the Big Blue Book (BBB) this book is the core rule book for the 4th edition of the game. Prior to the 4th edition the rules were spread out between five different books, which resulted in mechanics that were diffuse and inconsistent. The 4th edition was to fix both of these problems as well as combine all the rules from all the books into one cohesive whole.
The front cover artwork for all versions of the book was created by George Perez.
From the back cover, Champions contains:
