Contrasting Sequel Antagonist

Just as a sequel needs a contrast of heroes with a Contrasting Sequel Main Character, as well as a contrast of locations with a Contrasting Sequel Setting, so do its villains. After all, do we want to see the same battle over again? If the previous villain was a Non-Action Big Bad, make this one a fighter. A Punch-Clock Villain to a personal rival. A man with a troupe to a king in his kingdom. Or an extremist to an opportunist. Even changing genders and upping the Foe Romance Subtext are examples of this trope. At times, it is a case of Avenging the Villain, where the one seeking revenge is more emotional and personal than the cold and calculating original villain. In cases where the universe becomes more expanded and fleshed out, they may reveal ways in which the previous antagonist's actions affected their lives at times going as far as getting involved into offscreen Evil Versus Evil. This last one is even more likely if there is an ever-present conflict between two different communities/countries/classes and the villains represent rivaling (and perhaps extremistic) factions of the war, unlike the heroes who wish to bring balance and peace to all sides. This trope is notably more common than its heroic counterpart, as many franchises tend to keep the focus on the already established hero rather than replace them altogether. And should they eventually be replaced, it would be after a long period of Character Development finishing off their arc, and its generally viewed as Breaking Old Trends while new antagonists are viewed as the norm. Whereas with the villains, they don't get as much focus as the heroes and are often replaced for the sake of shaking up their series and keeping the established heroes and the audience on their toes. If a new main character is introduced, chances are a new villain will as well. The inverse where the old villain returns and a new main hero is introduced is rare.
