...Yeah... Oh! Disclaimer.
I do NOT own Edward or Fullmetal Alchemist. They rightfully below to Hiromu Arakawa.
I DO own Edward's CAT AND WOLF DESIGNS. Art theft is a crime, remember!
Although I do claim Ed's design as a wolf and a cat, I do not claim Edward Elric's character, regular design, or Fullmetal Alchemist at all. Thanks for listening to that long boring disclaimer. It is nessiscary though...
Thanks for taking a look! I hope you like my design.
