The 'Ultimate Showdown of Ultimate Destiny' meme originates from the legendary Flash animation released by Neil Cicierega (Lemon Demon) in 2005. The song describes a massive, chaotic battle royale between pop culture icons ranging from Gandalf and Godzilla to Batman and Shaquille O'Neal. This specific verse, mentioning Gandalf the Gray, Gandalf the White, and Monty Python characters, became a core 'list meme' used to represent overwhelming numbers, unexpected crossovers, or nostalgic internet culture. Users typically use this template to poke fun at overly complex movie franchises, multi-fandom crossovers, or simply to celebrate the peak of mid-2000s internet humor through its rapid-fire listing of characters.
