Doesn't look like any MOTU figure I've come across. I googled alligator/crocodile/reptile/lizard with both MOTU and GI Joe to see.
Keep in mind there was a LOT of knockoffs at that time too. I had a full knockoff off Snake Mountain with random evil minions that were nothing like the members of Skeletor's group.
Also a quick glance of Ghostbusters, Ninja Turtles, and Thundercats gives me nothing as well.
EDIT: Asked two large volume action figure collectors and neither of them recognized it. If this is an ebay listing and you message the seller, let me know b/c I'm really curious now.
