Aiden (The Originals)

Aiden is a werewolf and a true supporting protagonist of the Originals. This makes him a false antagonist as He is first introduced as a villain as him and his werewolf pack threaten Marcel and his vampires but when he realizes that Cassie and Finn use teenage wolves to be in the full moon and his brother is one of them, him and a redeemed Oliver team up with Hayley, Marcel and Elijah to move the teenage wolves to the Bayou, which succeeds.

Aiden will be a boyfriend-to-be to Josh Rosza, a gay vampire but their love could be unrequited as their species are in conflict but like the Romeo and Juliet inspired stories, it possibly will work out at the end.
