Photoshop Flowey (also known as Omega Flowey and God Flowey by fans and Flowey X in the game's code), is the entity created when Flowey absorbs the six human SOULs at the end of a Neutral Route. He serves as the final boss of that route if he has not been fought once before.

After absorbing the human souls, Flowey takes on the form of a grotesque, flower-shaped hybrid of plant tissue, human organs, and machinery. Consisting entirely of rendered images, Photoshop Flowey is stylistically different from anything else in the game.

He has two sideways jaws, with tiny lumps on the end, and has two orifices that resemble nostrils, as well as an eye on each side with moving and pulsating irises, located within hollowed mouths. On top of his "face", he has a box TV that switches between a smiling face with huge teeth and sideways eyes that flash red and green, and the bottom of the mouth is able to leave the TV screen. He has metal, bumpy pipes that are shaped into petals and connect to the TV and the jaws of his "face" and have floating eyes with moving and pulsating irises. He has many tubes that exit behind him, and big, thick vines that move away from him. He has cactus like hands with red claws, and dangling vines with leaves on them. His hands have the ability to retract and transform into Venus Flytraps.
