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.". 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. He should have a higher pitched, chirpy voice. Either gender can fit the description.
