  • first fic for the ship on here i think
  • Gaster is like a nonhuman looking skeleton that can change appearances
  • and is a giant monster lookin thing
  • inspired by huecycles design but
  • gaster is legit shifting into different fan interpretations
  • for body appearance
  • So every fan design of him is canon in this AU!
  • AU i made where gaster is every version of himself at the same time in one body
  • so hes living as every single AU morphed together if that makes sense
  • Author Is Sleep Deprived
  • i worked on this every single midnight if its a mess and doesnt flow well its because of that
  • but i need to pioneer gerster fics
  • oh yeah and
  • its more deltarune focused
  • but i think undertale fans who dont even know too much about deltarune can read it still. deltarune is his creation
  • and hes aware of the player. hes making the chapters with the player in mind
  • in this au
  • mention of burning alive and a dog dying from old age
  • gaster has a skeleton dog form! its not in this fic but maybe another gerster fic i can do that?

  Summary

  Gaster is experiencing the insanity of living in a void, where he's extremely lonely. He has his player, and his Deltarune, but nobody else.

  Until someone comes along for a bit.

  A turtle yaps on about life, and the skeleton of what's practically a smaller godzilla listens. And then more happens!

  (AKA: Author saw there were no gerster fics, and being the biggest gerster shipper alive in the 3 that exist, had to make one! thanks for everyone who supported me, couldnt do it without ya :3)
