W.D. Gaster

W. D. Gaster was the royal scientist before Alphys, responsible for creating the CORE. Gaster's Followers relay various explanations as to what happened to Gaster. One iteration says that he "fell into his creation," another says that "his experiments went wrong," and the last says that he "shattered across space and time." Characters such as the River Person and Gaster's Followers hint at his existence. Similar to Sans and Papyrus, he speaks in a typeface different from other characters.

Profile

Appearance

W. D. Gaster does not have an officially known form, but there are several rooms and unused assets found in Waterfall that point to what he may have looked like.

Room 268 and 269

In Room 269 (room_mysteryman), a figure widely believed to be Gaster can be found. The figure is black and white with a distorted, cracked face. Unlike every other NPC, they have no collision physics, and interacting with them will cause them to react in surprise and vanish while a sound effect plays.

This room can only be accessed when the game's "fun" value is set to 66. In this scenario, Room 268 (room_water_fakehallway), a hallway with a gray door, appears between Room 94 (room_water_savepoint1) and Room 95 (room_water11), the rooms with the crystallized cheese and Sans's telescope, respectively. The door in this hallway leads to Room 269.

Once the protagonist leaves Room 269 back into Room 268, the door disappears from the corridor, though it is possible to exit the room and trigger the door's reappearance, as the fun values do not reset until the protagonist leaves the hall. The corridor itself becomes inaccessible once the protagonist leaves it and all values drop to 0.

Upon attempting to call someone using the Cell Phone in either of these rooms, only the message "There's no response..." appears.
