LOL.
People aren’t supposed to be green and brown with little bumps all over.
At least, I don’t think they’re supposed ot be.
I have to consult the galactic guidebook again.
According to John Scalzi, the green ones are genetically modified super-soldiers. They are very dangerous.
According to Larry Niven, the lumpy ones are Protectors. Don't let their arthritic-looking joints fool you, it gives them extra leverage. They're extremely dangerous, and diabolically clever as well.
What the heck part of the Galaxy are you hanging around in, anyway?
