Become the mighty leader of the Autobots and defend Earth against the evil Decepticons with this Optimus Prime voice changer helmet! Don the helmet of Optimus Prime and lead your fellow robots into battle by pressing one of the three electronic buttons on the right side of the helmet to play five phrases from the 2007 "Transformers" live-action movie:

• "Autobots... transform and roll out!"
• "I am Optimus Prime!"
• "Megatron is in my sights!"
• "We must protect the Allspark cube!"
• "The Decepticons must be stopped!"

The second button will change your voice to sound like a robot's, while the third button will play conversion sounds when pressed. The straps allow you to adjust the headgear to fit anyone from age 5 to adult. Three AA batteries are required (included) for the electronics to function.
