Flowey
Flowey is the talking flower who greets you early and returns at major ending moments in Undertale.
First impression
Flowey offers a “friendliness pellets” tutorial that turns hostile. He mocks SAVE culture and pushes you to kill or be killed.
Later role
Flowey reappears around Neutral finales as Omega Flowey and comments on your EXP. Sparing or killing him changes post-credit hints toward Pacifist.
Spoiler boundary
His connection to Asriel is a late reveal. Finish at least one ending before reading theories.
