what if?

alright so you must know the Japan game nine sols if you don't jaut search it up or play it for free on game pass basically this takes place in the fuxi and nuwa fight but instead I added my OC in that's their older brother who's been gone for millenniums don't ask I haven't made a origin story .. yet anyway he is the tallest and biggest and has no sign or infection or somethin and can control fire and plays guitar and has a hammer infused wit lighting and in the hammer is a sword that can speed blitz and his name? korl ko-r-l I don't have a meaning anyways this is after the fight and fuxi almost does until korl stabs him with a syringe and somehow uninfects him back to normal and now korl is mad as hell and hits you to the sky and into his own arena with just a rock band in the back playing rock like in fuxi's fight with the music and also you're korl
