I had heard of these before, but I recently ran across them again (only on the internets, sadly. I'd love to see them in real life). Few things would make me happier than to get full on repaints/remolds of the SS Dinobots done up as the Prehistory Animals. Make them evil Decepticon clones or something, with the Prontosaurus being some sort of accidental fusion of the clones of Swoop and Sludge.
Prontosaurus came in both red and yellow chest versions. Obviously the yellow chest would be the way to go for the new character.
Evil Slag:
The Animal Mechanism
FINALLY Appears. 'Bout damn time.
As long as I'm dreaming, I want ALL the remolding. The gotta have the crazy horns, the etra spikes, the teeth. The whole 9 yards.
Evil Snarl, with only the derpiest of faces:
All led by evil clone Grimlock, the Tyuannasaurus.
And I insist that he comes with all his classic gimmicks! If he doesn't have Punch Storage, block, and Fighting Crow, I don't want it!
