The Doomguy and Isabelle meme, often referred to as 'Eternal Horizons,' emerged from the coincidental shared release date of DOOM Eternal and Animal Crossing: New Horizons on March 20, 2020. Fans of both franchises began creating fan art and memes depicting the silent, hyper-violent Doom Slayer and the polite, industrious Isabelle as best friends. This stark contrast between extreme gore and peaceful island life resonated deeply with the gaming community during the onset of global lockdowns. The meme is typically used to represent unexpected friendships, the duality of a person's hobbies, or simply to celebrate the wholesome bond between two complete opposites.
