The 'Three Heroes' meme originates from the hit indie RPG Deltarune by Toby Fox, specifically referencing the 'Legend of the Delta Rune' prophecy. The template features the game's protagonists—Kris (the human), Susie (the monster), and Ralsei (the prince from the dark)—standing together as the destined saviors of the world. Online communities adopted this dramatic imagery to categorize various real-life or fictional trios that fit these three distinct archetypes. It is commonly used to celebrate a well-balanced team, highlight a chaotic group dynamic, or irony-post about unrelated objects that happen to come in threes. The meme thrives on the nostalgia and epic aesthetic of the game's introduction while providing a versatile framework for any 'triple threat' scenario.
