The decepticon communications officer, Soundwave is Megatron's most loyal servant. Exactly why he is so loyal, we have no clue. Turns into a boombox/SUV/jet (depends on continuity) and usually stores his minions, Laserbeak, Frenzy, Rumble, Ratbat, Ravage and occasionally Buzzsaw, in his chest.
He is also the greatest transformer of all time.
