0 a person who does harm to or punishes someone who has done something bad, especially to the person’s family and friends:
They were cruel avengers who stripped a suffering land of the last remnants of civility.
If he is a vindictive avenger, he will expose criminal behaviour and punish it no matter what.
In his black overcoat, he has the look of an avenger who with a wave of a hand could bring down the wrath of God.
