W.D. Gaster is a mysterious and largely unknown character from the video game Undertale. He is not directly encountered during a standard playthrough, and his existence is primarily alluded to through cryptic dialogue from certain NPCs and hidden game files.

According to in-game dialogue, Gaster was the Royal Scientist before Alphys. He is credited with creating the CORE, a powerful energy source for the Underground. However, Gaster is said to have "fallen into his own creation," resulting in his disappearance from the game's world and from the memories of most characters.

Despite his obscured backstory, Gaster has become a popular figure within the Undertale fandom. Fan theories abound regarding his true nature, motivations, and potential role in the game's lore. He is often depicted as a fragmented being scattered across time and space, and his fragmented dialogue and existence add to the overall mystery surrounding him.
