What name have you had for the longest? I was called The Zorua from Feb 2010- Sep 2010.
I'd bet Turtwig Lover lasted over a month.
Both Blazevoir and RyeKew lasted about seven months. I'm not sure which I had longer but it was probably just by a few days.
I've had Game Maker for so long, people still call me GM.
With all three instances combined, it's CuboneKing.
Shadow CuboneKing is second, and CuboneKing Rudolph is third.
I had (variations of) insomniac for a total of probably 6+ months.
But I just changed it.
Genosect i had for a long time.
I had it so long, people still call me Geno XD
I was Ash&SilverFangirl and Red&SilverFangirl, but when I started here I was pokefreak493 but then I changed it to my SPPf name, XxPikapikaxX, and I've had countless more. xD
