Rumble is Soundwave's subordinate. While Rumble's body may be small, his enormous attitude and combat strength mean he will take on any Transformer without hesitation. He and his brother, Frenzy, frequently act together, and they specialize in coordinated combat. His main weapon, his hammer arms, cause powerful tremors, disrupting urban areas, but Frenzy loves playing pranks, and to him, it is nothing more than a fun game.
