Rumble

Rumble is one of Soundwave’s loyal cassette warriors, known for his brash attitude and eagerness to fight. He transforms into a cassette tape but in robot mode wields powerful piledriver arms that create earthquakes and shockwaves. In the cartoon, Rumble often provides comic relief with his tough-guy posturing, though he proves dangerous in battle when put to use. His loyalty to Soundwave and the Decepticon cause is unwavering, even if his overconfidence sometimes gets the better of him.
