How funny of you to ask, we were talking about it with @stylincheetah (Undertop Gaster’s creator) yesterday!! Their fifth marriage anniversary is coming up on March 5th and we really want to do a little something for them. We haven’t introduced enough content of Ink’s two dads after all, we’d love to show more of them! 💛
Undertop Gaster ( @under-top ) is Ink’s main father figure, they slowly bonded over the wisdom and experiences the reality of knowing of the out!code world gives. Although Gaster has two sons (Undertop Sans and Papyrus), he does consider Ink as part of his family. Gaster is a really charismatic ringleader who plays pretend as an in!code, but he has a lot of insomnia, hallucinations and nightmares from his past as an out!code as well as the genocide timelines of Undertop following him.
Zephyrtale Gaster (or Aster) is from my first AU Zephyrtale! He’s been exiled for doing harmful experiments on his own body for the sake of science by turning himself into a blaster, and had to leave his friends and his two little brothers (Zephyrtale Sans and Papyrus) behind. He lives in seclusion on a tower where he nurses over wild blasters and does scientific researches about astrophysics.
Being completely in!code and having no idea about the AUs, Aster is completely lost when he ends up in Undertop after having been teleported due to the event of a Gaster pile back in 2016 (this is a bit long to explain so I’m making this short I apologize), and he meets Undertop Gaster there. They both quickly understand that they’re fragments of the same character, like pieces of the same whole. He also meets Ink! The whole story of these three follows from there!
There isn’t much written or made of them unfortunately, but I hope I could give you more information! It’s rly nice to get an ask about them, thank you so much 💛
