Goku Black is the villainous counterpart of Goku in Dragon Ball Super, a version of the hero corrupted by the god Zamasu, and his cold, formal insults became a signature part of his screen presence. Short clips of his dialogue circulated on anime soundboards and in fan edits, where the phrase you scoundrel stood out because it sounds old-fashioned next to modern slang. Creators keep using it for dramatic callouts because it instantly signals arrogance, betrayal, and a villain who believes he is morally superior.
