I'd like the power of deception.
No, I didn't say dishonesty. What I'm getting at is the extreme power of being able to fool others "at need" as a survival tool. Let's say some dude decides to off me (a situation which has occasionally been threatened, though I couldn't say how serious each threat was or was not). With a deception superpower I could easily fool him into thinking I was already dead, or moved to Venus, or was too dangerous for him to comtemplate action against me.
You still think deception is a bad thing? Well, maybe it is. After all, it's the most important thing in all of war: Make the enemy army think you're going to THIS, then do THAT and wipe 'em all out. It's the basis of all fishing: Make the poor fishie think he's getting a snack, and instead he BECOMES a snack. It's the basis of most competitive sports--a boxing head fake, a football or basketball play the other side never saw coming. And the basis of poker, chess, etc.
Yup. I want the superpower of deception.
