A Towering Friend or Foe
Both the Robosen Optimus Prime and Grimlock auto-converting robots are much larger than the original G1 Transformers toys they’re based on, and even Tomy’s Masterpiece editions that were released years later in Japan. But while Grimlock in T.rex mode towers over Optimus Prime in truck mode, in their robot modes, Optimus Prime is actually ever so slightly taller than Grimlock, just like the Autobot leader should be.
