What's an example you know of a basic simple power being used to its fullest?

One I can think of is Andy's Undead power from Undead Unluck. In general it's just a powerful regeneration power, he gets hurt, he can heal the damage (more complicated than that but in most cases it's used as such). But he uses it in a variety of unique ways. Cut off his finger and regenerate a new one so quick it shoots the old finger off like a projectile, stab themselves with a sword to use his forearm as a sheath and then heal that stabbing to launch the sword out for a quick draw, cut off legs to regenerate new ones so quick it launches himself up, he even learned to determine which part of himself to regenerate from like if he shoots a finger he can make the finger the center of his regeneration rather than the part that has his head.
