Supernatural Signs, I would totally get the anti-possession as a tattoo!< as soon as I reach the age when my parents wouldn't kill me for getting a tattoo. And old enough to buy a tattoo. And old enough to get a car to drive to the tattoo place.
But shouldn't the x-ray be able to see through the adamantium? I mean, he does have bone claws under there. Either way: it looks awesome!<--- um his bones were bonded with adamantium (not under it) and you can see metal in an ex ray.
