Rumble is often partnered with Soundwave, along with other cassette Decepticons Ravage and Laserbeak. Because of his coloration on the original cartoon, he is sometimes identified as Frenzy, as the color schemes for Frenzy and Rumble were actually transposed. Throughout the animated series Rumble was perceived as tough and full of firepower, but his fellow Decepticons, being much larger, were significantly more powerful. He gave the weaker Autobots, such as Hound, Mirage and Bumblebee hard times on the battlefield, due to their lack of warrior-like capabilities, although in one episode, Hound beat the tar out of Rumble during a huge Autobots/Decepticons battle. Due to his small size and average intelligence, he displayed a Napoleon complex and often tried to prove his loyalty to Soundwave and Megatron through tough talk and destructive tendencies. Rumble debuted in the series opener "More Than Meets the Eye part 1", being used by Soundwave and Starscream to destroy a power station with his piledriver arms, and later to cause a tidal wave that would allow the Decepticons to create energon cubes at a nearby dam. He battled and defeated Hound underwater, although the Autobot would get his revenge later on. Rumble appeared regularly throughout the series, although he rarely had major roles, and was usually called on to create tremors with his arms (such as in "Enter the Nightbird" or "Attack of the Autobots").
