Flowey (/ ˈflaʊi /) is the first major player to play Undertale. Flowey is a key opponent in the path of impartial and genuine peace and can be regarded as an opponent in the genocide. He develops a remedy by sharing "friendly bullets" that are actually bad bullets, and reveals his idea of "READ OR MURDER". Flowey looks like a deliberate golden flower. Its structure consists of white androecium, six yellow leaves and a bright green stem. Flowey is able to change faces to reflect different personalities, and he can imitate the faces and words of others. In some cases, she imitates Toriel and Asgor, as well as her ex-husband at the end of a brutal murder. It also mimics the face of the main character before the final battle in neutral ways. Flowey began to work under the influence of friendship and good manners. He often greets the main character with a tropical slang, such as "Hello!", Calls himself "your best friend", and at the end of the sentences, like his father, adds polite words such as " Gosh "and" Golly ". When he unveils this dress, he often calls the main character "idiot."
Flowey is ruthless and angry and accuses the main character of not following his idea of "killing or being killed". However, he also criticized the main character at the end of the irons if they killed any monsters. He is strong, cunning, deceitful, and considerate of circumstances, if need be. He keeps his mind in the middle of FAIRY because he was able to SAVE himself in the past. He is also very cowardly as he kills his ex-father to confirm the protagonist, brutally trying to save his life after the genocide.
The main reason for Flowey’s brutal and insane behavior is his inability to physically care for people. Like a lifeless flower, it is neither man nor beast. Because he has no soul, he can only sympathize with the compassion, love, or common sense for a person, but he can only seek pleasure through the intricate and restless curiosity that arises from his ability to "change the world with a solution".
