The fight

Y/n p.o.v

I was walking to the gym so I could fight p.j. Once I get there I see dream, nightmare, error, ink, horror, mad dummy, frisk, chara, forge, and fresh. I glare at horror cause I knew he told them. "Ugh where is he" I say. I then see p.j. walk in with the other jocks behind him. I turn to him. "First one down loses" I say with no emotion. "O-ok" he says. "Ok lets start" I say with emotion this time. I wait for him to strike. He summons bones and shoots them at me. I just side step and dodge them. I shoot a fireball at him which he easily dodges. He smirks thinking I was weak cause I used a small  move. 'Look behind you' I say in p.j.'s mind. He turns around and I shoot a fireball at his back. "Ow" he says as it hits him. He shoots error strings at me. 'Wow I haven't seen these since the original universe' I think as I dodge them.  I summon a gaster blaster a ride it over to p.j. while everybody just stares in shock. I shoot a ball of ice at p.j. he dodges it. He shoots error strings again. 'Ugh I can't let these grab me or they will see that I have a monster soul. Not to mention they would question the horns and wings' I think as I dodge. He shoots bones again I dodge all but one that goes through my hand. "Ow" I say. It made me mad that he done that so I started to float. My left eye glows f/c. My theme song begins to play. 'My true brothers theme together.' I think.

I turn p.j.'s soul black and cast a sleeping spell so he would sleep. I sat him down on the gym ground. I float back to the ground and pull out the bone. "Ow" I say. I start to limp out of the gym but Forge stops me. "Y/n are you remembering the original universe" he asks me. I just nod.
