Soundwave is the spy master of the Decepticons. One of Megatron's earliest followers, and, many believe, instrumental to his rise, he uses his tentacles and a veritable army of Minicon Deployers to learn everything there is to know about his allies and his enemies. He was never very chatty, but these days, on Earth, he's become near silent, communicating by playing back recordings of other people's conversations. He just sneaks about, patiently looking for Autobot transmissions and creeping you out. Since the incapacitation of Megatron, Soundwave acts as a restraint on Starscream, reining in his rather volatile emotions, and ensuring that Starscream's less than subtle ambitions are held in check.
Soundwave has the ability to receive transmissions from anywhere on the planet, bar the shielded Autobot Base. This allows him to spy on every being on the planet in the hopes of picking up Autobot-related communications.
Soundwaves fellers have the crushing powers of 50 Boa Constrictors enough to take down both Optimus Prime and Megatron though he remains extremely loyal to Megatron and dares not attack him. Soundwave has a demon deep inside that when angered takes over luckily Soundwave keeps himself in check, angering him is not advised.
Soundwave dares those with a strong will to seek their death to hurt him and Soundwave will make you wish come true with a slow, agonizing, painful and Unbearable death. He hopes you enjoy having your limbs ripped off as you slowly die with energon/ blood dripping all over the ground when he is through with you. Do not take him lightly.
