What medium and idiom hath wrought

Now for my next trick, which is to express or interpret Intruder via the concepts and mechanics across many role-playing games. It’s not a trivial comparison, as he’s based on very situational and preparatory concepts: “did it thirty minutes ago,” “crazy prepared,” “knew all about that,” “investigated and surveilled it all better than you did,” “stole your power,” and that potential mud-stomper of all dramatic conflict-of-interest, mind control. So it’s not just about whether he wields gravity or lightning powers, or how many guys he can take out with one zap. How does role-playing logic deal with this kind of content across games, or rather, what different forms of logic are employed across them?
