Gaster is the enigmatic, largely unseen figure at the centre of Undertale lore, known mainly through hidden dialogue, Wingdings text and fan theories rather than a direct appearance. That mystery has made him a favourite subject for fan-made audio, including warped alphabet readings that play on his cryptic, glitchy image. Shared across soundboards, gaming videos and meme edits, this second ABC version keeps circulating because it is short, instantly recognisable to Undertale fans and easy to drop into a creepy reveal.
