### Season 3

After the bike wrecks, they merge into one giant alpha and begin to charge Isaac and the girl. An electrical bolt fired from a "modified tazer" causes them to split back into two separate individuals. Later, they appear at Beacon Hills High School and attack the mysterious girl again, along with the rest of their pack.

Ethan rooms with Danny during the team trip. The pair make out until Ethan begins to hallucinate and leaves to try to kill himself. Stiles Stilinski stops him. In the morning, he tells Scott that Derek is still alive. He blames him for the death of Ennis and says either he must join their pack, or be hunted down by Kali.

Ethan reveals the Twins' backstory to Scott and Stiles: they were the Omegas of a pack, always the last to eat and the first to be abused, until Deucalion found them.

## Personality

Aiden was an aggressive person who did whatever he could to survive and who had a very quick temper. If Aiden had his way, he would kill any potential threat so that they could not come after him later, and he was very prone to the Werewolf version of the phrase "shoot first and ask questions later." When he finally gained Alpha status after years of being at the mercy of their ruthless pack, Aiden took advantage of his new-found power and used it to dominate those around him as best as he could as a way to compensate for the powerlessness he had felt up to this point, though he was still one of the lowest-ranking members of the Alpha Pack. However, his romantic relationship with Lydia Martin eventually showed a softer side to him, as he never once used his power or authority over her and was very respectful toward her wishes, demonstrating that he was capable of being compassionate and kind.

Upon learning that Deucalion lied about Derek killing Ennis and had really killed Ennis himself, Ethan defected from the Alpha Pack entirely and instead went to the McCall Pack for help in stopping Aiden and Kali from killing Derek.

Both Ethan and Aiden's association with the McCall Pack helped them to grow into more selfless and compassionate people who were willing to put their life on the line for their friends. In fact, Aiden ended up meeting his death while in a battle with an Oni to buy the pack time to defeat the Nogitsune, and though he gave up his life, he was able to kill the Oni in the process, proving to all who knew him that he did have the potential to be a hero.

## Physical Appearance

Aiden is a lean and muscular young man of medium stature, with slightly tanned white skin, reddish-brown hair, and hazel eyes, though Ethan is slightly taller and leaner than his twin, Aiden, though just as muscular. The twins preferred dressing in trendy clothing, choosing designer jeans, v-neck t-shirts in various colors, black leather jackets, and motorcycle boots.

## Powers and Abilities

Aiden and his twin brother Ethan possessed all the standard powers and abilities of an Omega-level Werewolf, including superhuman physical attributes such as strength, speed, agility, durability, and senses; the ability to shapeshift into a partially-lupine form that includes glowing blue eyes, fangs, claws, a ridged brow, and mutton chops; the ability to absorb pain from living creatures such as animals, humans, and other supernaturals; and animal instincts such as tracking and the ability to assert dominance over other canine creatures such as dogs.

As for Alphas, they also possessed the ability to merge into an extra-large Werewolf, an Alpha roar that could force creatures of lower rank to transform, and the ability to turn a human into a were-creature through a bite or a scratch, though this could also kill the human in question in some cases. Finally, they also could inflict wounds on lower-ranking supernatural creatures that would take longer to heal than normal wounds. These powers were lost when their Alpha form's body was killed by Jennifer Blake.

## Weaknesses

Ethan and Aiden possessed all the standard weaknesses associated with werewolves, which included wolfsbane, mountain ash, electricity, the modified canine distemper virus, and the lichen known as letharia vulpina. After getting their neck snapped by Jennifer Blake, the twins lost not only their alpha spark but their ability to merge as well. This made them weaker and more vulnerable to attack.
