Nat Loh's biggest challenge when designing Grave Clobber was turning the original version from Trap Team (an Earth elemental villain with "undead mummy vibes") into a Water elemental Skylander, which had an open slot. After pulling some desperate parts, Nat revamped the Mayan mummy influence into a different Luchador direction, researching various lucha libre moves as a result. Notably, Grave Clobber's Gator Geysers was originally named "Sar-croc-phagus", but was changed due to it being too hard to say.

Skylanders Imaginators is the first game in the Skylanders series that doesn't introduce a new figure/form of the characters Gill Grunt, Terrafin, Eruptor, Trigger Happy, and Stealth Elf.
