Our favourite angry flower who was previously a monster child. He was turned into Flowey via experiments that Alphys performed on SOULs. For this voice, be pretty high-pitched. A Texan accent could also work, but that's on a case-by-case basis. There are certain lines of Flowey's that are meant to sound more demonic, like "He's DEAD." in the second audition line. When saying these lines, try to make your voice sound more wild and angry, or just demonic in general.
