I will go through all of mine because I have a few minutes to waste.

Astos - without a doubt the best FF1 character. honestly. >:O

Fiend - thought I had to re-register when the board reset when all I really needed to do was log in. stupid n00b. >:O

Astos - I changed back because I felt like it. >:O

Roostos - I asked Roogle in his Eyes on YOU thread if I could call him Rooster. He countered by asking if he could call me Roostos. So I got a name change, much to Roog's dismay.

Wuppalitos - not a forum name, but used on #eoff. I was forced to use it by Roogle because he got confused in chat. shortened to Wuppa. this is where my LJ name comes from too, btw.

Sarbles - another Roogle name, since he begged me to change from Roostos.

Sadia - Roogle's SISTER's name. xD

Denmark - something happened in chat where Psy said something about Denmark and I changed my nick in chat to that and soon after got my forum name changed to that and like have used it ever since plzkthx.
