X was originally a computer virus that came out of a corrupted command block in the minecraft world. X possess doggo to destroy everything in sight after a while doggo started 2 resist X's commands so X copied doggos code to create a body so he can finish the job. X knew doggo will become a big problem so he challenges him in a sword fight. X lost and gets part of his ear sliced off. X admits defeat and lets doggo kill him. Doggo doesn't kill him but forgives X and X becomes one of the good guys. Thats the story and X is basically a clone of doggo.
