History
Mister Y was once a rich undefeated martial arts master who attracted the attention of Mr. X. X challenged him to a fight, and Y underestimated him. X cut off his legs, one of his arms, his eyelids, some of his fingers, lips and tore out his vocal cords, leaving him a shell of his former self. He took the name Mister Y and began to use his resources to hunt down X, tracking him to Madripoor. Y hired Deadpool to take out his foe, but due to the interruption of their fight by a gang of Headhunters, Mr. X decided to let Deadpool live so they could fight in fairer circumstances, so long as Deadpool told him where Y was hiding. Two weeks later, Mr. X attacked and killed Y in his home.[1]
