It's Scar. Gill had the mask with the... gills? LOL.
Scar is beefier because it's Anderson's design, and hot toys stuck with that... Plus, the way I have Scar posed, he just looks that much bigger. I really like him like that, it gives a nice bit of diversity to my collection to have P2 Elder, and Predator 2 nice and lean, Wolf even leaner, and Scar the resident big ol' badass.
Whenever I think of more stuff I can do with these guys in a funny situation, I surely will take plenty of pics!
