These three figures are called Nuclear Apes. They are 3D printed by Invictus Miniatures (check them out on Etsy). When I saw them I thought they looked exactly like the White Apes in the film, John Carter of Mars (2009) and could not resist buying them. I have a bunch of John Carter figures (John, Deja Thoris, a bunch of Tharks, some Red Martians, even Woola. (One of the many projects to paint at some point!)
I've included a pic of the Apes from the movie to show you the comparison. Take a gander.
