Vengeful Heroes also known as Seekers of Vengeance, are heroes who commit their actions under the given of vengeance which is also named retribution or revenge whether it be for a wrong done against them or their people/race.

They are almost the same as a Nemesis, but with a few minor differences, a Seeker of Vengeance is a specific type of Nemesis, being concerned only with revenge while a Nemesis involve all types of motivations; also, a Nemesis is an enemy who is made through the villain's own behaviour, but a Vengeful hero may already be an enemy to the villains and is seeking vengeance for a noticed wrong dealt to them by the villain.

Some heroes can be fallen if their vengeance makes them do villainous things because of this trait.
