I've been wanting to do a Fantomex ever since I saw the Hasbro prototype for that Marvel Legends poll. Most of those were quick mock-ups by their employees and Fantomex didn't come close to being voted into the line so I figured I'd give one a try since I'd been meaning to get a little more technical with my airbrushing anyways and gray on white's pretty tough to do evenly without the whole figure looking sorta plain-jane.
I used a Hasbro Quicksilver to save on joint rub at the ankles (where it happens most on Hasbro stuff) and added gloves from Forge, a SHIELD agent belt, Ultimate Nick Fury coat, and a Union Jack head. I sculpted the trademark fine lines on his mask, then the rest was all paintwork.
