Im pretty sure the most common neuteral ending is the King Papyrus one

Bro low-key thats what I did. My route was the “kill everything in my way” route

The first time I played I lost to him so much he offered to skip the fight and become friends

I was doing true pacifist

when i first played that's what i was gonna do cause i didn't care about sparing until a came across Papyrus and i decided to reset cause i decided to use the mercy button

Near Genocide/Alphys Ending you mean

Yeah sure
