Teen Wolf Wiki

Deucalion was an Alpha Werewolf introduced in Season 3 of Teen Wolf and played by Gideon Emery.


Deucalion speaks with a British accent. He was an Alpha in 1977 and, according to Gerard Argent, bit and turned Hunter Alexander Argent.

Sometime later he returned with his pack to Beacon Hills at the behest of fellow Alpha Ennis to seek vengeance on Gerard and Chris Argent for the death of one of his Betas. While Kali didn't seem to care, Deucalion sought peace by meeting with local Alpha Talia Hale and then trying to meet with the Argent hunters.

The meeting with Gerard was a trap and Deucalion was blinded. While still recovering, one of his Betas attempted to take over and Deucalion killed him. In doing so, he learned that Alphas become stronger when they kill their own Betas.

He then convinced both Ennis and Kali to kill their packs and join him, creating The Alpha Pack. He also showed the Twins, Ethan and Aiden (who were Betas at the bottom of their pack), how to merge together. Consequently they killed every member of their pack, saving their Alpha for last, and joined his Alpha Pack.

When he returned to Beacon Hills to claim Derek and Scott for his pack, he wore dark glasses and carried a cane with a spearhead concealed beneath the red tip at the bottom.

After multiple skirmishes, the Alpha Pack is disbanded and his eyesight restored as a way to weaken the Darach, Deucalion is given a choice to amend his ways or next time there would be no mercy. He made up for his evil deeds by aiding Scott's pack as a spy in Theo Raeken's pack and offered guidance to Scott when Gerard returned for revenge until he is mortally wounded by Tamora Monroe.


According to Ms. Morrell, who is a clinical psychologist and Druid emissary to Deucalion, he is on a "narcissistically psychotic" mission to form the "perfect pack" and, to that end, wants a True Alpha like Scott McCall to join him.

She says Deucalion's desire to possess Scott's uniqueness was in conflict with an equally strong desire to destroy Scott's potential to become a True Alpha by getting him to kill.
