Cartoon Network: Super Secret Crisis War!, Vol. 1

The devious demon Aku has called together a League of Extraordinary Villains—composed of malevolent miscreants from different cartoon universes. When their evil robots show up in the worlds of The Powerpuff Girls, Ben 10, Samurai Jack, Dexter’s Laboratory, and (even) Ed, Edd and Eddy, it’s up to all of these fearless heroes to band together and put an end to the League’s nefarious plot of inter-dimensional conquest!
