Flowey is the first major character that the protagonist encounters in Undertale. 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." He is manipulative, devious, a cunning planner and subtle if the circumstances require it.
