Zero and x are two characters I used to play on the Nintendo, Zero is a humanoid swordsman whom doesn’t care and wants to be the best. Master of the sword and has zero tolerance. I was almost like him at one time except the swordsmanship (I bet with practise I could make it ;). Now I just like the look of him. His brother X is a kind hearted humanoid that wants to do his best and helps anyone in need. And lastly 1 it’s just a number nothing interesting just needed a number for the username.
