Soundwave is one of Megatron's most reliable troops, and he has positioned himself comfortably and irreplaceably in the Decepticon upper command structure. Though only Communications Officer, Soundwave stands at Megatron's side as a confidant, akin in rank to Starscream, but unlike the treacherous Seeker, entirely loyal. He has Cassetticons; small Cybertronians who transform into cassette tapes. He transforms into a cassette player. He has Ravage, Rumble and Frenzy as his main cassettes.
