Grayson Hunt, from Bulletstorm.
He's a juvenile, drunken murder machine who takes great joy is being a juvenile, drunken murder machine. He's a protagonist striped down to exactly what 90% of protagonist are, without the fake facade. That, and he's got some wonderful lines that I just love.

Hey, You wanna make out? Just two gruff military hardened dudes sitting in an elevator snuggling out their woes in a totally hetero way.
Need to get some pads for my ass. Old gal wasn't built for that much abuse.
Here comes Butterdick Jones and his heavenly asshole machine!
I named him Waggleton P. Tallylicker, but I never got the chance to tell him... He will be remembered...
He's my favourite robot pal! Ishi was okay but he wasn't fifty feet tall! It's a pretty cool party, come and see! You can get a robot and come killin' with me.
It's a murder party, starring me!
Look at that, all this exposure to radiation has turned our good general into a giant pussy.
What? What does that even mean? You're gonna kill my dick? I'll kill your dick! How 'bout that, huh?
