Alpha

Alphas are the progenitors or sources of a certain line of supernatural beings, aka "the original monster". However, according to the Alpha Vampire, they do have "mothers" of some kind.

According to lore, all Alphas have a connection with their entire race, which allows the Alpha to locate them.^{6.02 Two And A Half Men} For the Alpha Vampire, this connection also allows communication through shared visions or telepathy.

Alpha Shapeshifter

Alpha Shapeshifter disguised as Samuel Campbell

First appearing in 6.02 Two And A Half Men, this shapeshifter has gathered a following of its 'offspring' and is apparently generating more shapeshifter children by posing as human husbands and impregnating their wives. When Sam and Dean rescue one of its children, the Alpha Shapeshifter storms the Campbells' compound and kills Mark Campbell, overcoming several gunshot wounds and tranquilizer darts, as well as a silver knife to the heart. It then reclaims the baby from Dean and leaves. This shapeshifter is able to transform in just a few seconds without shedding its skin.

At some point this Alpha is captured and taken to Crowley's monster prison. During its interrogation in 6.10 Caged Heat, it takes the form of Crowley's meatsuit. Crowley wounds the Alpha with an iridium knife, and threatens to skin its children in front of it. The Alpha continues to insist that it does not know the location of Purgatory, and says that the shapeshifters can make more children. Frustrated, Crowley beheads the Alpha with a machete, killing it.

Alpha Vampire

The Alpha Vampire, as he appears when he is being Interrogated.

The Alpha Vampire is first glimpsed in 6.05 Live Free or Twihard, briefly flashing in the minds of its "children" as it commands them to recruit more for its army. Nothing is known about this particular monster, aside from the fact its "messages" can be heard by all vampires and render them unconscious.

In 6.07 Family Matters, Samuel and his people capture the Alpha Vampire and attempt to interrogate him, but he is extremely resistant to pain and doesn't give Samuel any information. After Samuel leaves the room where he is being held, he is approached by Dean and Sam and he reveals to them that, though he is the first vampire, he has a mother. He also tells them that Samuel is torturing him for information about Purgatory which is where the souls of supernatural creatures go, and where it is located.

Shortly after their conversation, he escapes his cage and almost escapes completely, but demons appear and take him away on Crowley's orders. It is revealed that Samuel has been working for Crowley, who will to continue to question the Alpha Vampire about the location of Purgatory.

Alpha Werewolf

The Alpha Werewolf is referenced in 6.08 All Dogs Go To Heaven. Crowley speculates that a series of daylight attacks, in which the victim's heart is removed, are werewolf activity, and could lead Sam and Dean to the Alpha Werewolf. However, the attacks are actually the fault of a skinwalker.

Alpha Skinwalker

The Alpha Skinwalker is alluded to in 6.08 All Dogs Go To Heaven. It appears the plan is for a Skinwalker pack leader in a town to oversee the recruitment of other Skinwalkers in a town, which live with families as the pet dog. On a signal from the pack leader, the Skinwalkers will "turn" their families, thus exponentially increasing the recruitment of Skinwalkers.

Alpha Djinn

The Alpha Djinn is referenced in 6.10 Caged Heat. As Crowley is walking through the cell block he goes to the Djinn, Brigitta that Samuel captured in 6.01 Exile On Main St. by asking her if she's ready to tell him all about her daddy.
