Aiden Steiner³

Loyalty and Redemption: Despite his "bad boy" facade, he demonstrated deep loyalty to those who earned his trust. At the end of his life, his greatest wish was for Scott to accept him into his pack so he could prove he could be a "good boy." Supernatural Identity: Aiden was a werewolf who initially belonged to Deucalion's Alpha Pack alongside his twin brother, Ethan Steiner.

Unique ability: The twins had the physical ability to merge to transform into a single giant and powerful werewolf.

Youth as Omegas: Before arriving in Beacon Hills, Aiden and his brother Ethan were the "Omegas" of an extremely brutal werewolf pack. They were constantly abused and were at the bottom of the hierarchy until they met Deucalion.

Ascension to Alphas: Deucalion taught them to control their fusion ability. Following his orders, the twins murdered all the members of their original pack, including their own Alpha, thus granting them Alpha status and their place in the Alpha Pack.

Mission in Beacon Hills: They arrived as infiltrators to destabilize Scott McCall and Derek Hale's pack. Aiden approached Lydia Martin with manipulative intentions, but ended up developing genuine feelings for her.

Loss of Power: During the confrontation with the Darach (Jennifer Blake), their fused form was "killed." Although they survived as individuals, they lost their Alpha spark and reverted to their Omega state.

Aggressive and Protective: Unlike his brother Ethan, Aiden was much more impulsive, prone to violence, and had a volatile temper. His primary motivation was always survival and protecting his brother.

Power Complex: Due to the years of abuse he suffered as an Omega, Aiden used to use his strength to dominate others as a way to compensate for his former weakness
