I imagine that, in his humanoid form, 682 has a bunch of tattoos-

He's got scales on his right arm, some chains on his left, some teeth and eyes, and the number 4 wrapped in chains on his chest....

And on his right wrist..... is something very important.

There's a rose and a very important date.

2/18/07. Rosie's birthday.

682 cares alot about his sister, so it's only natural he'd get a permanent reminder of her on him.

Rosie plans on getting a similar tattoo of his birthday on her body too, when she's old enough.

682 also is great friends with the people at the local tattoo shop, they know him and he knows them.

So yeah.
