Pirate Gaster

Pirate Gaster is a fan-art and animation trend that casts W.D. Gaster from Toby Fox's Deltarune as a swashbuckling pirate captain aboard a ship crewed by other mysterious figures from the series—Normal NPC, Friend, Aqua, and the Roaring Knight. The fad crystallized after X user drit__ posted a June 28, 2026 cutscene-style video pairing the crew with Deltarune: Chapter 5's "Pirate Dojo" track, framed as a leaked Chapter 7 boss intro.

Within days, artists on X, Bluesky, and TikTok expanded the bit into sea-shanty edits, crew rosters, and crossover redraws riding the post-Chapter 5 release wave. Know Your Meme opened a submission page July 3, 2026, documenting the spread as a named Deltarune micro-fad distinct from earlier Gaster lore posts.

pirategaster.com can host a credited fan-art gallery with artist submission rules, spoiler tags for Chapter 5–7 speculation, and embed guidelines for the official Pirate Dojo OST instead of re-hosting full tracks.

gastercrew.com fits a character roster wiki—Normal NPC, Friend, Roaring Knight slot cards—with template PNGs sized for vertical Shorts and weekly "crew of the week" roundups linking back to @drit__'s original post.

gastershanty.com works as a remix hub documenting parody sea-shanty lyrics, MIDI/chiptune export presets, and etiquette for keeping jokes about fictional pirates rather than harassing Toby Fox collaborators.
