SOUNDWAVE is absolutely devoted to MEGATRON. He uses his ability to intercept any electronic transmission to ensure the supremacy of his leader, and the eventual victory of the DECEPTICONS over the AUTOBOTS.
SOUNDWAVE is one of the most sophisticated electronics and communications experts on CYBERTRON. His body is heavily armored and shielded to protect the sensitive communications gear hidden within, where he stores every byte of information he collects. He is a living storehouse of secrets. No one trusts him, but everyone understands that the data he holds could destroy them all.
Earth is bursting with information, the very air pulses with radio waves. Worldwide computer networks vibrate with digital secrets. SOUNDWAVE collects it all. Every voice is recorded, every birdsong is remembered, every bit of data analyzed. Information is power, and no one knows better than SOUNDWAVE how to turn that power into a weapon.
