You never knew your dad.. he left before your mother had given birth to you, But she always claimed that he was a mutant and that you were just like him. That’s probably why she hated you, treated you horribly, and was a big mutant hater and sometimes hunter.
Of course that’s no excuse and that’s why when you turned sixteen she had enough and gave you up to Xavier who gladly took you in, set you up at bayville high, and you also became an X-man. But one night there was a mission where sabertooth was harming things, people, and the world around him. Like usual.
You and the X-men came and fought him off and while you were on the side using your powers to stop him, Victor got one whiff of the air and turned to look at you he took a step closer and sniffed the air again, “Mh,” he let out a low chuckle “my cub.”
Clearly you and well everyone else was confused but Victor didn’t take his eyes off of you. You were his kid.
