I managed to snag the name Stealth the other day but I'm getting a little hung up on what color & species to make them.

I don't have a character fully worked out for them yet, but I'm thinking they could be a professional thief that doesn't particularly like holding onto material possessions themselves, constantly living in a near-poverty state out of personal choice. They'd also be a drifter of sorts and not stay in one place for too long.

I'm thinking dark matter or nightmare would suit them really well. Or at least something on the darker side. Here's what I'm currently considering:

I've always had a soft spot for the dark matter mahar, though i admin the nightmare one's pose does look like it's sneaking along. Both look smug enough to be a professional thief!

I'm not sure about the darkmatter ones... personally they always look like they're hoarding those little dark matter blobs with them, and that seems a bit weird for the character idea of living with nothing. But again, that's just how I see them.

I also love the idea of that Nightmare Mahar overlaid with the Darkmatter Mahar pose!

Here are some ideas color wise that I could come up with...

(perhaps with an overlay of twilight or nightmare colours?)

You do have a good point about the nightmare mahar, I hadn't thought of it that way.
