Lancer is a recurring character in Deltarune, Toby Fox's role-playing game that began with Chapter 1 in 2018, where he appears as a young, prank-loving prince from the Dark World. His distinctive laugh became a favourite among fans, who clipped it for edits, streams and soundboards celebrating the game's humour and charm. Because it is short, expressive and instantly tied to Lancer's playful personality, it continues to be reused in Undertale and Deltarune fan videos, reaction clips and gaming memes years after its debut.
