Zira was the chief antagonist of the Lion King II: Simba's Pride and was the former mate of a now deceased Scar who led an exiled pride in the wastelands, amongst the members of her pride was her son Kovus (who heavily resembled Scar) and although Zira claimed to be fond of him she regularly abused him in her obsessive quest for revenge against Simba and his pride for the death of her mate and her subsequent exile.
