They might argue a lot, but I think they would.

NNnNnnnnnnno. Least, not yet.

It could happen! I can almost see a storyline develop:

He's from a world where blood and sand are the only constants, where every day is a fight for survival in their brutal desert homeland (which, of course, makes me think of Dune) and honor is the only thing you can call your own. Weakness is not tolerated and the strongest warriors are as gods among their people.

She's a rave-rainbow demon from a techno-world of color and sin. They live for entertainment and scandal, where boring is the dirtiest word in the book and subterfuge is second nature.

I see a lot of fighting for dominance and more than one dirty innuendos flying over our rugged warrior's head. Now go, make it so. <3

I see them meeting at a con, so yeah it could happen.

Grey, Black, and Red...yeah, sure.

Eh...I doubt it.

Not unless it was in a Yaoi manga... XD

The chances are very slim.

No - more like enemies.

In a companion sense, maybe.

Uh, I don't think so. One's too colorful for the other.

i don't think so.

....Yes, actually. (Hey Shad, nice to see you again.)
