Seeker of Vengeance (or "Vengeful Villains") are villains who commit their crimes under the premise of vengeance (also called retribution or revenge), whether it be for a wrong committed against them or their people/race. Similar to a Nemesis, but with a few slight differences: First of all, a Seeker of Vengeance is a specific type of Nemesis, being concerned only with revenge while a Nemesis encompasses all types of motivations; also, a Nemesis is an enemy who is created through the hero's own actions, but a Seeker of Vengeance might already be an enemy to the hero and is seeking revenge for a perceived wrong dealt to them by the hero, i.e. Opal Koboi from Artemis Fowl; Seekers of Vengeance may also be pursuing revenge against neutral characters or even other villains in Evil Vs. Evil scenarios (for example Ransik or Jean Descole).
