Clash of the Nicktoons

The villains of the Nicktoons Universe have declared war on the Nicktoons heroes. It's the ultimate clash between good and evil. Eight heroes vs. eight villains compete in a March-Madness-style bracket. Every weekday at 4pm for the first three weeks of March 2010, one Nicktoon goes head-to-head with another Nicktoon in an unforgettable match-up. The winner moves on, the loser goes home. The battles continue until only one Nicktoon remains and is crowned as champion.
