Steven Universe and Undertale Mashup!!!
Sans/Apatite and Papyrus/Carnelian fuse into Comic Papyrus/Pietersite.
Frisk is still human in this au.
Asriel/Flourite's gem was smashed so Alphys/Orange Calcite tried to "fix" him. But it didn't work out right.
I like the idea that since Gaster/Obsidian's gem is cracked, making him all gooey, he can move his gem around and even put it inside him to hide it.
Sans also makes jokes about being hungry cus his name is “Apaptite”. ;)
Oh, I also realized (after I drew this) that I made Sans’, Pap’s, and Toriel’s gems where you kill them (chest, neck, stomach)... Oops...
