Finally got a sweater on mine. It made such a huge difference, he is now by far one of my more favorite figures. The waist on the Pro was loose and made him slouch alot, so I put a layer of electrical tape around it. Work great.
Now I am sucked in and must pursue Cobra Commander and the Cobra trooper.
Thats funny, I just put a sweater on mine and you're right, it makes a huuuuge difference. I cant recommend it enough if you're like me and very untalented when it comes to body swapping or intricate modifications. This is a simple but effective way to make him appear to look more 'bulked' up.
And like you, it went from where I was kind of embarrased for him to where he's one of my favorite 1/6 figures in my collection.
A big thanks goes out to all you Freaks who make GREAT suggestions to everyone when it comes to making your figures even more special!
