Holy shit, Undertale Help From The Void by Vennis Delepaz

This is disbelief

Oh f**k oops

I haven’t seen regular Disbelief so and my dumbass thought that sans sprite was the Last Breath sprite, so I thought it was the mix of them

Don't worry, in the intro for help from the void it says one time sans replaced papyrus in Snowdon leaving papyrus to judge the human

Yeah, it’s both colliding

Well, three colliding as well. (Rejuvenation)
But yeah, I just thought it was different sprites

I haven’t been in the Undertale AU community for a while, geez.
I’ll have to look at some stuff again, see if Green Sans is out, yada yada

The green sans fan game is out

Holy shit

Okay I’m going to check it out, bye!

The difference is that papyrus is stronger in disbelief and sans is alive in help from the void
