Holy shit i know (almost) all of these guys TwT
Ultratale Sans (or Delta!Sans)
I thought the second one was Negafell (as in Negative Underfell) Sans, but Iām wrong. I recognize him but I forgot the name of the AU
Third is Alphatale, right?
Then obviously Something New/Killertale
Aftertale
Regular Sans
And Horrortale
