Flowey (/ˈflaʊi/) is the first major character that the protagonist encounters in Undertale. Flowey serves as the main antagonist for the majority of the game, specifically the Neutral and True Pacifist routes, and can be considered a deuteragonist for the Genocide Route. He provides an introduction to the mechanics of encounters by sharing "friendliness pellets," which are actually harmful bullets, revealing his philosophy of "KILL or BE KILLED".
Howdy!Flowey introducing himself.
FLOWEY the FLOWER!
Flowey has the appearance of a conscious golden flower. His structure has a white androecium, six yellow petals, and a light-green stem. Flowey can contort his face to show various expressions and can mimic the faces and voices of other characters. He mimics Toriel and Asgore in some situations, as well as his old self at the end of the Genocide Route. He also mimics the protagonist's face before the Neutral Route's final battle.

Initially, Flowey operates under a facade of friendliness and politeness. He often greets the protagonist with southern slang, such as "Howdy!", calls himself "your best friend," and, like his father, appends polite words such as "gosh" and "golly" to the ends of his sentences. Whenever he drops this guise of friendliness, he often calls the protagonist an "idiot."
Flowey has a malevolent and cruel disposition, berating the protagonist for not following his "kill or be killed" philosophy. Despite this, he also criticizes the protagonist at the end of the Ruins if they killed any monster. He is manipulative, devious, and a cunning planner and subtle if the circumstances require it. He retains his memories between SAVEs because he was once able to SAVE. He is also shown to be extremely cowardly, as he kills his former father to appease the protagonist in a vain attempt to save his own life in the Genocide Route's conclusion.
Flowey introduces the concept of the Bullet Board and calls his bullets "friendliness pellets."
- If the protagonist dodges three times, his friendly act slips and he hypocritically snaps at the protagonist for leeching off of him.
- The background music lowers by one semitone each time the bullets are dodged, before slowing, lowering the pitch, and stopping entirely.
- Before his third attack, Flowey questions the protagonist's mental capacity, before bellowing in frustration "RUN. INTO. THE. BULLETS!!!" before quickly looking directly at his text and changing the "BULLETS!!!" in the speech bubble to "friendliness pellets."
If the protagonist runs into his bullets, he announces his central philosophy. Regardless of whether the protagonist dodged Flowey's bullets or not, he then attempts to kill the protagonist with an unavoidable ring of bullets, but Toriel intervenes and saves the protagonist.
If the protagonist killed Flowey on a previous Neutral Route (or if they aborted the Genocide Route, even if they spared him), he does not interact with them again until the protagonist reaches New Home again. If the protagonist spared him, he appears in the beginning of the Ruins again and advises them on what to do. If the protagonist gained EXP, he reminds them not to kill anyone. If the protagonist gained no EXP, he reminds them to befriend everyone. Resetting the game before completing a Neutral Route causes him to repeat his "tutorial" after assuming that the protagonist is pretending not to know who he is. After resetting a Neutral Route multiple times and repeating Flowey's initial encounter, he becomes annoyed and questions if "you have anything better to do."
If the protagonist resets a Genocide Route at any point after exiting the Ruins and before the route's completion, Flowey says "Really, <Name>? Well, do what you will. I'll be waiting for you!" before leaving.
At the exit to the Ruins, Flowey judges the protagonist's actions up to that point. Flowey does not appear to judge the protagonist if he was killed in a previous Neutral Route or if the protagonist aborted the Genocide Route in a previous playthrough.

After the Ruins, Flowey is seemingly absent until the end of Asgore's battle. However, backtracking in some rooms allows the protagonist see Flowey burrowing back into the ground on the edge of the screen.
If you let me live... I'll come back. I'll kill you. I'll kill everyone. I'll kill everyone you love.Flowey, if spared after his boss battle.
If the protagonist decides to kill Asgore, Flowey appears, destroys Asgore's SOUL, and absorbs the six bottled human SOULs. If the protagonist spares Asgore, Flowey appears and kills Asgore himself. Then, the game crashes and Flowey's battle begins after opening the game again.
After he is defeated, the protagonist has the chance to spare or kill Flowey. Flowey requires the protagonist to offer him mercy multiple times before he flees, unsure why the protagonist is being nice to him.
If the protagonist loads or finishes another Neutral Route, Flowey does not absorb the SOULs because he knows that they would rebel again. Instead, the protagonist is able to exit the room and receive Sans's Neutral Route phone call.
Well. You DID do what I told you. I guess it's up to me to get you a REAL happy ending.Flowey
If spared after his battle, Flowey gives advice to the protagonist on what to do during subsequent Neutral Routes. If the protagonist gained EXP before his battle, he asks the protagonist to prove his philosophy wrong, as he thinks it may be meaningless. Flowey also offers unique dialogue if the protagonist only killed Asgore and tells the protagonist that they wasted everyone's time. If the protagonist earned no EXP, yet they have not met all the requirements for the True Pacifist Route, he mentions that the protagonist should get closer to one of the main characters, depending on who they previously befriended.
The protagonist can then recover their previous SAVE file and follow his advice.
If the protagonist kills Flowey, he recognizes that the protagonist can kill before becoming "just a regular flower."
If he was killed after his battle, Flowey does not leave a message for the protagonist after the credits close, and, after a reset, does not appear until after the resolution of Asgore's battle. Flowey then berates the protagonist for thinking that killing him solved anything. He explains that he was brought back when the protagonist loaded their SAVE file and that they still cannot achieve their happy ending. 
If the protagonist aborts the Genocide Route, Flowey becomes upset with the protagonist. However, he then proclaims that the protagonist just wanted to see everything in the Underground and will eventually return to their malicious ways.
True Pacifist Route
- Flowey and Mettaton represent the two characters with voice clips; Flowey says "That's a wonderful idea!" at the end of the Ruins on a Genocide Route.
- This phrase is a higher-pitched clip of an old McDonald's commercial originating from the 1960s as seen in this video by Adam Powell.
- There are other clips within the commercial which also match voice and sound clips within the game. Examples are times 2:47 and 3:05, where Photoshop Flowey's "hurt" sounds originate.
- Flowey's laugh is not a new asset and can be recognized in other media. It was originally a Warner Bros. sound effect mostly used in Pink Panther cartoons and has appeared in titles such as the PlayStation title Tomba! and the Homestuck soundtrack The Lordling, also by Toby Fox. The full, unedited laugh can be heard here.
- It can also be heard as part of the background music on page 7677 of Homestuck.
- If the player attempts to name the fallen child "Flowey," the screen reads "I already CHOSE that name" and prevents the name from being used.
- In Hard Mode, Flowey appears alongside the Annoying Dog after the protagonist finishes Toriel's boss fight.
- In a joke thread on Starmen.Net, when Undertale was called "UnderBound 2," it was revealed that Flowey was planned to be the reincarnation of "Face," who was the protagonist of the non-existent EarthBound hack, UnderGround.
- The artbook mentions that Flowey was partially inspired by Face from the "NES Godzilla Creepypasta" written by Cosbydaf.
- Flowey's character might be inspired by flowers from EarthBound, which Toby did include in one of his hacks.
- Flowey has the most battle sprites of any character; he has dozens of expressions that he uses in the battle room.
- In the Japanese translation, Flowey uses "boku" and refers to a person with "kimi" alongside his past self Asriel.
- When Flowey surrounds the protagonist with a circle of friendliness pellets during his initial encounter, he commands them to "Die." This is noticeably written in a font that is a no-spacing variant of the Korean typeface Gulim Che in bold, making him, Sans, Papyrus, and W. D. Gaster the only characters with the ability to speak in a typeface different from Determination Mono, the standard typeface of Undertale.
- It should be noted that Flowey still usually speaks in Determination Mono; he only speaks in this font once.
