I kind of hate the fact how I tend to make pretty simple character designs, but in this case I wanted to make an alien character that didn't look like the typical "dangerous reptillian humanoid green/gray men" look; this was the best I can come up with. It was difficult to come up with a unique design when literally the only idea of an alien's looks are this. I'm still kind of playing around with looks, but for now I like this current design.
This little guy comes from a species where their body is made of a green gelatinous plasma kind of material covered with a thin membrane. Ever since they started to live alongside the humans, they realized very quickly that our Sun's ultraviolet rays are pretty harmful to them. To combat that, they use our sunscreen which is surprising effective for them. It's not there fault, since their planet is further from their system's star.
Unlike a typical race of aliens where they want to conquer and eliminate life on entire planets, they offer the exact opposite; they are of a peaceful kind. In some ways, they're better at being friendly than us humans, which is probably not a surprise given how terrible we tend to be.
Soon he'll be added to the line-up along with the rest of the 2422 cast.
