Rule 204 

If a fictional character exists, then it can be cosplayeable.

It doesn't matter how difficult it is, or if it's a manga, anime, videogame, movie... you'll find someone cosplaying.

I didn't accept Rule 204. I thought about one of the hardest cosplay possible. Think about "bahamunt" of Final Fantasy series. Go to google images. Accept Rule 204.

Rule Of Honor 

Who ever appeals to the law against his fellow man is either a fool or a cowered, who ever can not take care of him self with out this law is both. For a wounded man shall say to his assailant. If I die you are forgiven, but if I live I will kill you. Such is the rule of honor.

If a man kills one of your family members It is your right to envoke the Rule Of Honor to avenge her death.
