Frenzy

Frenzy is the BLUE Decepticon cassette tape that runs around with Soundwave, that is until Soundwave died, so he then teamed up with Barricade, until he died. Now he serves as one of SoundBlaster's most loyal soldiers in the Neo-Decepticons.

Now remember one thing that the cartoon got wrong, RUMBLE IS RED AND FRENZY IS BLUE.

He killed many Autobots that mistook him for Rumble. He has the ability to control sound and creates a frenzy whenever he uses his powers.
