Here are two for now, I'm going to update soon with others! These names may or may not be placeholders...since these are minor characters I haven't thought about that too much.
Digger is a seemingly useless member of the Helix gang, but he is actually one of the most valuable because of his ability to tunnel behind enemy lines and steal supplies. As you may soon see when I post some more of the designs for the Helix gang...these aren't supposed to be the most intimidating kinds of aliens (I have the Krell for that) but instead are able to compete with the other gangs due to the unique ways they can adapt to the landscape.
And here is a ranger type character from the Aces. I'm not quite sure how she manages to hit her targets without depth perception, but she does.
