Skeksis Court, The Crystal Chamber, The Dark Crystal, Skeksis Lovers, There is one dedicated to Brooklyn, the red gargoyle, my fave. And some dedicated to Randall Boggs too. I forgot to mention him too, from Monsters, Inc. There's so many to pick from with Ninja Turtles. You can look up Group names too to decide what you like and want.
I got a couple of groups inspired by Evillious and Kingdom Hearts
