Soundwave

"If there's one Decepticon you need to watch out for, it's Megatron's Communications Chief, Soundwave. He's not one to talk, but he's dangerous all the same." —Shockdrop's description of Soundwave

No Decepticon is as loyal or dedicated to the Decepticon Cause than Soundwave. He is Megatron's Communications and Surveillance Chief as well as his most loyal serveant. Soundwave is cold and almost completely devoid of any emotion. He can speak, but chooses not to, preferring to communicate through replayed Cybertronian voice recordings, including Humans he encountered. Soundwave is very skilled in combat and will not hesitate to finish off his opponents if necessary. Soundwave and his little pet, Laserbeak, will do whatever it takes to complete their assigned mission, and neither have failed yet. Soundwave is capable of using Ground Bridges to his advantage, which has apparently become one of his most favored signature moves.

Unlike most Decepticons, who operate publicly, Soundwave prefers to operate from the shadows, attacking only when absolutely necessary. On Earth, Soundwave mainly works to monitor all Earth-based transmissions as well as to locate new sites for the Decepticons to plunder the energy required to restore Cybertron. Like his Master, Soundwave was a Gladiator in the Pits of Kaon and was the only other Cybertronian to nearly defeat Megatron. According to official Cybertronian records, Soundwave is among the most dangerous of Decepticons, closesly followed by the former Air Commander, Starscream. Though stoic and possessed of little outward personality, Soundwave is not without drives: he has worked hard to get where he is, and he guards his place in the Decepticon hierarchy fiercely. On top of hearing all in his role as Communications Officer and Decepticon spy-master, he is actually capable of "reading minds" by scanning and decoding the electrical impulses that carry "thoughts" in both organics and Cybertronians, and he will not hesitate to use what he learns as blackmail to keep himself high in Megatron's esteem. As such, Soundwave is not popular among rank-and-file Decepticons, who see him as a two-faced snake and wouldn't mind abandoning him on the battlefield... if they thought Megatron would let them get away with it.

Soundwave also appears to be a tactical genius, often formulating strategies to complete whatever mission he has been assigned. He knows when the time to fight is, and when it is time to retreat. Perhaps this is what names him as being one of the most dangerous of Decepticons. That, and his fearsome combat skills that often see him standing over his enemy. Much to his amusement, big and tough Decepticons like MoltenStorm and Death Strike are actually afraid of him.
