Champions Villains - a trilogy of Champions supplements - describes the bad guys of the Champions Universe in thorough detail. It doesn't describe every single villain, of course (three books, even big ones, aren't enough for that), but within these three volumes you'll find over 300 villains - the most important, intriguing, dangerous, and defining supercriminals in the setting. This book, Volume 2, covers villain teams: groups of villains (usually of roughly equal power) who form a group so they can commit more profitable crimes, protect one another, and perhaps even take over the world.
