Top-Heavy is the realist of the pair he makes up with Skyfall, though others would call him the "nagger" of the two. Skyfall's daydreamy behavior annoys the "down-to-earth" Top-Heavy greatly.
- Skyfall with Top-Heavy (Action Master, 1990)
- Top-Heavy is a robotic rhinoceros. Pushing down on his tail flips his head and a chunk of his inner body around via a spring-loaded mechanism, revealing a (non-firing) blaster. Folding his legs up forms his triple-barreled "electro-pulse machine gun" mode, which can be used by any regular Action Master figure. His gun barrel can be extended by attaching the handgun from any carded Action Master.
