{1} I didn't pick it for symbolism. I picked it for coolness factor, and to fit in with the Fallout motif, as I am a powersuit mogul. Not really symbolic for much except...that I like Fallout and powersuits.
{2} I refer you to the enjoyment of Fallout part.\
{3} Can't change avatar now. Lazy.
{4} Since I can't think of this in terms of names, I'll explain my opinion of this in terms of type. That is, the best avatars are funny avatars, preferably animated. The worst ones are the entirely sick ones, which I do not see many of. (Point of reference: People without avatars are neutral in this case.) The creepiest? Uhhh, none of them. I find the creepy and macabre to be enjoyable, so creepy vibes are just GOOD vibes.
