Can I just say that Skullface was a bad villain? He was so under developed.
It's not like he did anything wrong, he wasn't really the generic villain. Anyone with the self awareness to call himself Skullface is already better than a generic villain.
But he was just disappointing.
Skull Face was still great in the tapes. The Code Talker interrogation tape is one of my favorites and James Horan has an amazing voice and delivery. A good actor can do wonders with a bad material, so that's perhaps why I have a higher opinion on the character than he really deserves.
The problem is that his performance in the cutscenes is like a complete opposite. Not even Volgin was this laughably hammy (WOULDN'T YOU AGREEEEE) and he really doesn't do anything in the game to properly challenge the hero. And they've set him up so well in Ground Zeroes... he has an interesting backstory, a decent motivation and a plan (putting the stupid magic parasites aside) and what he did to Paz and Chico was absolutely disgusting. All the makings of a solid villain were there, but squandered.
