You should totally use this for Roy's banner.

Or if those don't work, I would just use the one you did for his thang with the sunglasses or the profile pic I used with the blanket or whatever he has in the picture... o_o

As for Kat, I, for some odd reason, typed 'mary elizabeth winstead cheesecake' in the google image search bar and this is the first thing it gave me. Don't ask me why cheesecake.

She is clearly either dressed as cheesecake in swimwear or she is holding a box with some cheesecake in it.

Also, if that's Kim I'm immediately just gonna say he and Roy banged before Thael/Roy was a thing. Go away, Kat, you can't have any of the men. No men for you. Alone forever. D:<

EDIT: I did not realize how large those images really were. Apparently... my zoom doesn't work properly. Also, give Roy tattoos, Rockette, so many tattoos. I don't care if it's not mentioned or a canon thing. Actually, I'm totally kidding, but I'm positive you could do it if I weren't.

DOUBLE EDIT: Oh, no, my zoom does work; I forgot to click.

TRIPLE EDIT: Did everyone but me realize that Mary Elizabeth Winstead was Ramona in [i]Scott Pilgrim vs the World[/i]? Because I just now realized it, after so many years.
