Ok so as far as how much work I've ever put into a custom this one takes the cake! This super skrull has the powers of Iceman, Venom and Pyro! What a nightmare for any hero! Heres a breakdown of the recipe:
Head-Ultimate Goblin baf with sculpt
Body-Scorpion Venom
Arms-sculpt (ice and flame device)

The ice arm alone took A LOT of sculpt lol and it also has about six layers of paint to make it look like ice! I also filled in the hole where the scorpion tail went in. This guy took a while but I think it was worth it. Also the head is attached my magnet and doesnt hinder the neck articulation.
