Oh, man, I totally agree. I'm tattooed, too, and the pain is worth it. I dislike that awkward peel-y stage the most because I kills me not to pick at it, but you think about it--it's a week/two of discomfort but then it's just a totally awesome part of your skin forever. My biggest problem is that my current job isn't 100% thrilled with the fact that I have a tattoo, but I had it when they hired me, so that's their problem. It's not visible most of the time when I'm in uniform but sometimes I have to wear a dress and you can see it then, so I have to come up with creative solutions to make it less visible.
An Animorphs tattoo is neat. I don't know if I would ever get one, but it wouldn't be out of the question, since it's the interest that I've had the longest. If you get a big battle scene on your back you should totally take a picture because I imagine that it would be AWESOME.
