Input Crisis is the story mode for Cartoon Network vs. Nintendo 2: Punch-Time Smash Bros.
Mr. N, one of the Cartoon Network announcers, finds an NES Power Glove and brings it home with him. He gives it a test drive, but it soon messes with the television's input settings and creates an inter-dimensional rift!
The TV Remote, which has been replaced since the events of Cartoon Network: Punch-Time Explosion, is quick to realize this. He sends Zenyokus the Input Angel to find heroes to put a stop to this madness.
