Profile/Abilities:

Although Rumble isn't much older than Frenzy, he is the "big brother" of the two, the one that Frenzy looks up to and tries to emulate. Rumble is small, but always acting tough, putting on a "street punk" demeanor in the presence of the bigger Decepticons whom he admires, particularly Megatron and Soundwave. He follows orders eagerly and without complaint. Has a quick temper and mean disposition toward enemies. He can use a set of pile drivers to transmit immense low-frequency groundwaves to create powerful earthquakes. His small size limits his physical strength, but his ability to shatter the ground makes him difficult to approach in a fight.
