Rumble
As part of Soundwave’s group of cassettes, Rumble was the loudmouth and brashly diminutive robot of the pack. While not the largest in stature, no one was more loyal to his leader or had the heart to go toe-to-toe against Autobots or Decepticons in defense of Soundwave. With Laserbeak, Frenzy, and Ravage have all made appearances, it sucks the studio missed out on including the robotic spy.
