Kind of a random thing, but I have to say that I do Not like the Slime Creature interpretation of Rouxls. I get why people headcanon that, I do! He's got that thing going on with his mouth that looks like it could be. Melting. Or some shit. But I Do Not Like It dgsgsfsh

If you've happened to see my art of him, you'd know I personally give him a galaxy pattern across his full body! (If you want an example, here's a semi-old doodle page of him)

I guess it doesn't make The Most sense for him to be galaxy themed, given that he's. A playing card, but. Pretty :) dgdgshf

It does sort of fit, though. As the rules card, he's connected to the universe through his ability to change its laws, if only slightly. Thus, he looks as though he is the universe.

The galaxy pattern continues fluidly across his body. Like, his coat and his pants don't have separate patterns or anything. It's all just one big galaxy. It's constantly moving and shifting, too, albeit slowly--you probably wouldn't notice it unless you were actively watching him.

He's... Mystical. As though he doesn't belong in his world (just as his sprite is different from Every Other One in the game with its white outlines). Looking at him is like looking into a portal, and if you reached out to touch him, it would almost be surprising to meet a solid body and not actually grasp the galaxies within.

Because of the whole "galaxy pattern running uninterrupted across his entire body regardless of clothing" thing, I like to think that Rouxls has some sort of reverse chameleon effect on his clothes. No matter what he wears, everything changes colour to match that same galaxy pattern (aside from white, which remains the same). If he were to take off his coat and someone else wore it, it would just be black or something.
