Heracles qualifies. Both as Alcides [Corrupted Heracles that's lost his divinity from Fate / Strange Fake], and IMO  True Heracles from his Lore [The 12 Labors are penance for the family that was murdered, giving him access to all his Noble Phantasms, and what is penance but vengeance against yourself?].

Kingu [A Mesopotamian Elder God that has a grudge against the younger gods], and Boudica are also listed as Avenger candidates.

Medb and Quetzalcoatl could also qualify under special circumstances, apparently.
