According to my friend Chef was already described in the books. He has oily brown hair and freckles.
Your friend lied. I've read them all. The closest thing to a description is something along the lines of "good looking, in an animalistic sort of way." Now, I know that is not an exact quote, so, fellow readers, please don't go rush to look up that conversation between Halsey and Cortana, and come back shouting 'Nuh-uh, that's not what she said!'
Anyhow, I think it would be funny if Chief took his helmet off to reveal four jaws and a snakelike neck =).
I've never played (what is it, Half-Life?) but I'll take a stab at Freeman. His first spoken words would be "Huh. Didn't realise I could do this." (referring to talking.)
