Flowey

Flowey is a flower with a white face, six yellow petals, and a green stem. He uses vines as hands. Once a kind-hearted prince among monsters, his mind was reincarnated into a soulless, unfeeling flower after his death. He lost his emotions and started committing terrible acts. Flowey initially pretends to be friendly to lure you in. He will act nice at first, gaining your trust before ultimately betraying and trying to kill you.
