This is my all time favorite custom. I loved the Pretender shell of Skullgrin as a kid but always wished he was more articulated. Fast forward a couple decades or so and I discover a new hobby that lets me do just that. This was actually one of the first customs I put together but took about 2-3 years to complete. I would add more & more sculpt until it covered almost every inch. Spliced parts of an original Skullgrin shell onto a Toy Biz ML 1st appearance Hulk, added the lower jaw from an old Mezco Popeye shark jaw accessory to give him a hinged jaw, and about a ton of Apoxy Sculpt. Full paint job and I finally have the Skullgrin I always wanted!
