Flowey

Flowey the Flower is a fictional character and the primary antagonist of the 2015 video game Undertale, developed by Toby Fox. Flowey is the first NPC the player encounters in the game, and introduces himself as a friendly and helpful talking flower, but quickly demonstrates himself to be a megalomaniacal sadist with more sinister goals.

Flowey is the final boss of Undertale's "Neutral" route; after absorbing the souls of the six fallen humans, he evolves into a grotesque form known as "Photoshop Flowey" but known to some fans as "Omega Flowey". In the "True Pacifist" route, he additionally absorbs the souls of every monster in the Underground, and reveals that he is Asriel Dreemurr, the son of Toriel and Asgore, reincarnated as a soulless flower.

Critics and fans have praised Flowey's characterization, backstory, occasional fourth wall breaking, and boss fights.
