in undertale there was a goat prince who lived in a hole, but he got possessed by his dead adopted sibling, climbed out of the hole, got his ass kicked, climbed back into the hole, and fucking passed away
years later a dinosaur with a phd used a syringe to inject the will to live into one of the flowers that bloomed on his deathbed. what this creates is a creature that’s sort of a 11 year old boy and sort of a plant and they dont have a soul so they’re emotionally inept but they really really really really dont want to die and thats what flowey is
depending on what ending you get their Boss Forme is either a madoka, the dead goat’s mary sue self-insert character, or a salad
