- Peter Cullen and Frank Welker as Sticks 'N' Stones: An evil Rock Lord who seems to be a conjoined twinned Golem with Sticks as the right head and Stones as the left head (from the viewer's point). For comedic effect, the two heads (each voiced by a different actor - ironically, Cullen and Welker are arguably best remembered as the voices of Optimus Prime and Megatron, opposing leaders in the original Transformers cartoon) regularly argue with each other. the name derives from the old saying "Sticks and stones may break my bones but words will never harm me.".

- Several other Gobots have cameo or walk-on scenes during the early stages of the film, including Fitor, Cop-Tur, Herr Fiend, Heat Seeker, Klaws, Sparky, Rest-Q, Dozer, Zeemon, Twin Spin, Twister and Stallion. In an odd animation error, Herr Fiend and Baron Von Joy's roles were reversed, with each Gobot fulfilling the other's role, and being referred to by name. This error is especially odd as it required several scenes of animation, yet the error is consistent throughout.
