Kenpachi's scar

Kenpachi probably got that scar before he was even in the Gotei 13. So I'm pretty sure that he got it in some random fight at some random point of his past.

I have no idea... I'd say that he fought someone epic before he joined the Gotei 13, یا he got into a battle when he was a squad member of 11th Division... Maybe even from fighting the former Kenpachi, even...
