Synopsis
It finally happened! Somehow, after multiple failed attempts, Pinky and the Brain have successfully conquered the planet! All hope is now lost--or is it? After being warned by his descendant Ace of what the future holds, Bugs Bunny decides to assemble a group to help avoid disaster. But which fearless soldiers will he send into battle? He won't. He's instead sending a unlikely team of out-of-control whackjobs. Freakazoid, Babs, Buster, Yakko, Wakko, and Dot are recruited to help save their world from ultimate dictatorship and possible boredom. Will their weapons, skills, and personalities be enough to defeat the scheming laboratory mice? This may very well be the end of our own sanity!
