Well after a weekend of painting he's finally done.
Made with Marvel Select Abomination he's HUGE. Bigger then Octopunch but I really wanted to make him pretty menacing.
I wanted to get a pretender inside this guy but learned I would have to sacrifice the "shell" in order to get a good sized figure to be Skullgrins robot form.
Using WFC Megatron was really the only option for me as his Pretender alt mode is a cybertroinan tank.
