Pirate Gaster
Pirate Gaster is a Deltarune fan art trend that recasts the cryptic W.D. Gaster as a pirate captain with a crew of obscure game characters. It started on X/Twitter in late June 2026 through a viral video by user drit__ and spread across TikTok and YouTube over the following weeks.
Overview
Pirate Gaster is a fan-made character concept and video trend built around the cryptic Deltarune figure W.D. Gaster, who fans reimagine as a pirate captain with a crew drawn from other obscure game characters1. The crew typically includes the Roaring Knight, Normal NPC as a shoulder parrot, Friend, Aqua and other figures tied to fan theories about the shelter beneath Deltarune's map6.
The trend blends actual game material, especially the "Pirate Dojo" track from Deltarune: Chapter 5, with speculative theories that surfaced after that chapter's release6. Artists put Gaster in tricorn hats and coats while his crew fills pirate-crew roles, connecting to a separate fan theory that Normal NPC butchered the ocean character Onion for the takoyaki sold at the Festival6.

Fan artists typically draw Gaster in a tricorn hat and pirate coat, surrounded by a crew pulled from Deltarune's obscure supporting cast. Common conventions include placing Normal NPC as a shoulder parrot, adding the Roaring Knight and Friend to the crew, and using either the "Pirate Dojo" track or DrakeTheroux's shanty cover as the audio for animation memes2.
