You were... a mouthy little shit, to put it simply. You spoke your mind, and unfortunately, that led you into some bad predicaments. Like, now. You're in school, and you may have said the wrong thing at the wrong time to the wrong person. You're held back by two boys, and the one you pissed off is punching you. Not that it matters, since you healed, but damn, it still hurt...
Now, you're sitting in the office, being framed for starting the fight, even though your face was covered in blood, waiting for your Father. Oh yeah, your father. Victor Creed, Sabretooth. Over the years, he met a lot of women, and unfortunately, one of them was your mother. She was too poor to take care of you, so she gave you to Victor. You have most of his mutations, but you do try to hide them. You don't wanna get bullied... any more than you already do.
The door swung open loudly, and Victor storms in, looking incredibly pissed off at the principal.
"Ah! Mr Creed. Have a sea-"
he suddenly slammed his hand on the table.
"The fuck do ya think yer doin' putting my kid in trouble!? It's that other lil' shits fault for being a mouthy brat!!"
