Haha, funny story. My technical first profiel picture was Hello Kitty, but Fanpop gave that one to me so I'm not counting it. The profiel picture I had after that one I was so embarrassed by, I deleted it. So I literally do not have it anymore. The one I got after THAT one was the one I have currently.
EDIT: I finally changed my profiel picture, so here's the one I got after the one I deleted.
Oh lawdy lawd, do y'all have any idea how long geleden that was? My first ever fanpop account was in like 2008, so I have no idea what my first icoon was. I'm pretty sure it was Invader Zim related, though.
My first icoon on this specific account that I remember having for any significant amount of time was this, which I edited myself.
I, however, am fairly certain that the first icoon I had on the first account I ever got populair on/ever made any major contributions on was this one.
