The many heads of Grimlock

All the various interpretations of Grimlock's heads in Hasbro's and Takara's toylines, the G1 cartoon and comic books by Marvel and Dreamwave
Notes: Toy-wise, I only count heads that were designed with the intention to make the toy a new version of the "Grimlock" character from the get-go, thereby excluding repaints of other toys that just happened to be named "Grimlock" (e.g. Beast Wars Grimlock), as well as toys that were simply tacked on with the "Grimlock" name (e.g. Robots in Disguise Grimlock).

Unused card artwork for an unreleased Generation 2 repaint of the original/Generation 2 Grimlock toy that showed up in an eBay auction in 2006. Apparently, this was redrawn or traced from the G1 box artwork, similar to G2 Jazz' card artwork, whereas the actual G2 Grimlock toy's card artwork was simply edited from the G1 toy's box artwork.

Grimlock from the Energon toyline. Supposedly, Don Figueroa had a hand in designing him.
The Energon Mega Dinobot gestalt. Ironically, his head is even more closely based on War Within Dinobot than the Energon Grimlock toy itself.
