What is (are) your most used Internet ID(s) and how did you come up with it (them)?

Death, ZeroGravity (My previous name on here), Venom.

I don't have a lot of imagination so I guess there's not that much behind it.

Death:
Why? because I simply like the black/red theme. and hiding that i'm actually an extremely sensetive guy.. );

ZeroGravity:
I can't remember where this came from, I always liked the name Zero but it was always taken so I just used
ZeroGravity instead after I heard about this sonic game. The reason I liked Zero itself because to me it meant you're not
above or below someone. you're equal. Far fetched, I know but whatever. (No, didn't came from Megaman).

Venom:
My favorite marvel character by far. He's on my background, my firefox theme and username for quite a few forums including StarBound.
He's just to awesome not to like.
