Oooh. Powerful. I've thought about making a kid with a mentat brain whose main power is super-extrapolation and intuition.
Like, he looks at the person, the way they move and talk and at their stance and their tics and their clothing and immediately understands quite precisely what makes them tick and how to work them, pretty much like machines - say specific words and the guy will become VERY ANGRY, say another set of words while behaving in a specific way and they will melt and start to like you. Though it will work on pretty much any system and not only people - so guy understands the weak spots of machines or football strategies, is great at investigations, stuff like that.

Too OP as well, what do you think?
