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.

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.
