The 'I'm Wing Gaster, the Royal Scientist' meme is a prominent ironic shitpost within the Undertale community, centering on the enigmatic hidden character W.D. Gaster. While the character's canon lore is dark and cryptic—revolving around his disappearance into the CORE and being shattered across time and space—the meme subverts this by giving him a goofy, high-energy persona. The 'Wing Gaster' phrasing specifically gained popularity as a form of intentional 'brainrot' or misspelling, often appearing in surreal videos and low-effort image macros. It is typically used to mock the intensity of Undertale theories or simply to inject a sense of chaotic humor into the character's mysterious backstory.
