Quick sketch of what Decay!Sans’ childhood was like compared to the ‘Deccy’ you guys know. It’s not a topic I’ve ever talk about in the main story plot but Decans’ past had a pretty dark start along with Papyrus. Both are experiment from no one else but DR.Winding Gaster.
As a child Decans or officially titled (S01AS-P1) was mostly obedient and easy to handle until his ‘brother’ Papyrus (S02AS-K1) arrived in his life, ending up questioning Gaster’s action that would affect his brother in any way. There’s so much I could say about them, but I’ll keep it for myself until I decide to reveal more~
