Use the special touch-screen Omnitrix to choose one of 10 different characters, place the iPhone over your mouth and start to speak (or roar!) and the microphone picks up your voice and the mouth will animate!

The app features all of your favourite characters:
Ripjaw,
Ben Wolf,
Stinkfly,
Grey Matter,
Diamondhead,
Four Arms,
Wildmutt,
Upchuck,
Cannonbolt
and Ben himself.

PLEASE NOTE: Ben 10 MouthOff is designed for the iPhone. It also works with 2nd generation iPod Touch but you MUST have headphones with a built in microphone. Ben 10 MouthOff will NOT work at all with 1st generation iPod Touch.

PLEASE ALSO NOTE:This application is not a voice synthesiser - it doesn't change your voice or make sounds!
