Honestly the reason Ultra wanted to fight is so he can permanently die(that’s what I heard) So Ultra decided to find someone that could actually kill him…but also so he can test his strength and etc but mainly so he can permanently die
Seraphim vs ultra is an interesting concept cause they are both biengs who absorbed the seven souls but ultra doesn't work in tandem with the souls unlike Seraphim it's basically a battle of the gods
the only reason im watching this undertale reaction is because i don't speak the language, so i know i wont understand them talking smack about me as a player. otherwise i wouldn't be here watching this.
