I had multiple.. A few I remember are as follow:
DRAGON~WARIOR (Yes, I know, it's spelled wrong)
Something like those. Lol, I know, those names are pretty cheesy. Keep in mind, this was around 4-5 years ago .
I had a few, some were retarded, some weren't. The ones most used would probably be....
KoNfUsIoN with some wierd letter in there somewhere
BlastGannon for a while
and I think I had SewerSniper for a while on there.
