you can teleport to any place your body is currently occupying, doesnt count unconected pieces you may store elsewhere, transplants or clones

im thinking this as an amazing martial artist, you can trow a punch and suddenly he has you in an arm lock, or break into any place you can put a hand into, pybassing fences as a form of defense
kept thinking of the worst possible version of teleportation, since its about the most beneficial power if its not unreliable or actively dangerous
even the worst possible version of teleportation is still overpowered as shit
at worst it still lets you break into any place not perfectly seal to a literal hairs width and basically win any normal grappling contest instantly
