I have this problem too.My showdown nick, Winry, obviously comes from Fullmetal Alchemist but I picked it because my username on another website was taken on PS and Winry happened to be free. I really have a problem with not having matching PS and forum usernames, haha.
Love your username, sounds amazing!Mine originated from the Fire Emblem weapon, but back in 2011, I also came across the anime Yumekui Merry, of which my favorite character in that series also shared my name, so I've taken both references (there's also a Yugioh card named the same but I never liked the Dragunity archetype).
You'll find me on Showdown and some other places known as Mystletaynn, in case the original was already taken.
I must be fairly royal then... :o Since im a purple too. :oI was originally Ghost Trainer777, mainly because I loved ghost types with an unhealthy addiction, and my brain was sucking at being creative that day. After some time past, I took on the persona of a ghost irl, and i eventually changed to Prince Phantom. Partly because i liked how it was a bit more official-sounding, but mostly because the name was purple and purple is the color of royalty :3
Simple but sweet! :DMine's really simple. Just my name backwards.
