Rumble

Rumble is your basic street punk: Small, but always acting tough as a cover. He's not exactly the most subtle of Soundwave's spies, but what he lacks in discretion, he makes up for by being the brawler of the group. He talks tough because he is tough. Quick-tempered and of a generally mean disposition, he follows Megatron eagerly, as the Decepticon leader lets him indulge in destruction. Rumble has a tendency to toss out a taunting rhyme at his enemies and is, according to Brawn, a "jerk" (or at other times, a "sawed-off nerd").

As the Decepticon demolitions expert, Rumble loves nothing more than to break things apart. His arms can transform into powerful piledrivers that, when pounded against the ground, can cause earthquakes, usually with fissures. He can be easily overpowered in a one-on-one match, though the real challenge is actually getting to him first. Even if you do, you usually need to get through his brother Frenzy either before or after you get Rumble.

In Ultima, Rumble was reformatted by Soundwave, who gave him the beast mode of a rhino alongside that of a CD and a missile. Rumble is currently a member of the Decepticon Elite in the Organization.
