Gaster Blaster Au - Tumblr Posts

i fucking love the gaster blaster sans and papyrus shit. yeah here’s undertale where everything is the exact same except these two can turn into some beasts. why or how it doesn’t matter it’s up to you but they ARE creatures. bald werewolves i don’t know

Was going to add color but kinda lost inspiration. Sans has a bad habit of falling asleep in trees and other weird places.

In my version of the Gasterblaster AU, the war between humans and monsters acted as a natural selection event, and only monsters with stronger magic survived; hence the characters have physical features that reflect their magic abilities.
