Promised Sans Novels & Stories

Dead Sans is this fascinating AU (alternate universe) version of Sans from 'Undertale' that's gained a cult following among fans. The lore behind him is pretty dark—imagine a Sans who's literally dead, but still lingering as a ghost or spectral entity. Some interpretations suggest he died in battle or due to the timeline collapsing, while others paint him as a vengeful spirit haunting the Underground. What makes him stand out is his eerie, translucent appearance and the way he interacts with the player, often blurring the line between ally and antagonist.

I love how different creators spin his backstory. Some AUs depict him as a tragic figure mourning his brother Papyrus, while others turn him into a sinister force. The 'DustTrust' AU, for example, ties him to a timeline where Sans becomes hyper-aware of resets and goes rogue. There's no single 'canon' backstory, which is part of the fun—fans can mix and match elements to fit their own narratives. Personally, I adore the melancholic takes where his humor is still intact, but there's this undercurrent of sadness. It adds so much depth to a character already beloved for his wit and laziness.
