Soundwave

One of a seemingly rare breed, Soundwave is utterly loyal to Megatron. Rarely speaking, but constantly listening, Soundwave is often the arbiter of good sense in heated debates. Yet he always keeps a part of what he hears and records to himself: blackmail material in case his position should ever be threatened. With assistance from his cassette troops, no secret is safe and no whisper is unheard. Soundwave also has an ability to read minds by monitering brain waves.

Outside of his cassette entourage, nobody really likes Soundwave. Even the other Decepticons don't trust him. The thing is, Soundwave doesn't care. As he says, information is power.
