“	Dean Winchester: An Alpha? Like- Samuel Campbell: Like all monsters come from somewhere, right? (...) First one, who spawned all the others.	”
	— Samuel and Dean in Two and a Half Men

Alphas are the very first monsters of each species created by Eve.

Characteristics

The Alphas are the children of Eve and the first of their respective species. As the first and oldest, they are also the most powerful monsters and are regarded as the parent of their respective race, since they were the ones who began populating each monster race once Eve had created them. According to Samuel Campbell, there is a ton of lore about the alphas, but until their emergence when Crowley started hunting for Purgatory, they were thought to be a myth.

Due to their close ties to Eve, the Alphas are aware of Purgatory and the location of Purgatory's gateway, as well as the existence of Leviathans, their ancestors.

Due to their advanced age and power, they possess very few weaknesses, often being immune to or less affected by major weaknesses that hold true for their respective species.

History

Origins

The alphas were created by the Mother of All Monsters, whose own origin lore indicates she is a primordial monster, born into Purgatory shortly after the creation of the universe, like the Leviathans.

Season 6

Two and a Half Men

The alpha shapeshifter appears before the Campbells to retrieve a baby shapeshifter; it was immune to everything the Campbells had to throw at it and was able to defeat the Campbells easily.

Live Free or Twihard

The alpha vampire showed all vampires of the nest Dean was currently occupying a vision of his location so that his army could gather to him.

Family Matters

The alpha vampire is kidnapped and taken by Samuel and Christian for interrogation, it reveals Samuel's motives of locating Purgatory. It seemed very interested in the fact that Sam had no soul. It escaped the Campbell's custody and snapped Christian's neck in a fight. It was about to turn Sam when Christian injected it with dead man's blood, which weakened it. Three demons then restrained the alpha, teleporting him away to Crowley's prison. Although snapping Christian's neck had no effect on the demon that was currently possessing him, the Alpha killed the actual Christian.

All Dogs Go To Heaven

The alpha skinwalker (off-screen) rallies an army of Skinwalkers who are ordered to turn the families of the pets they are posing as when directed. Also at the beginning of the episode, Crowley alludes to the existence of an alpha Werewolf.

Caged Heat

The alpha shapeshifter appears in the beginning of the episode taking the form of Crowley's host. He was being tortured by Crowley and was killed by a beheading because he would not tell him the location of Purgatory. Weapons made of iridium are capable of harming the alpha shapeshifter. At the conclusion of the episode, Castiel clears out Crowley's prison of all the monsters, of which it is mentioned at least a few alphas were there that were destroyed.

Season 7

There Will Be Blood

The Alpha Vampire returns, having escaped Crowley's prison before it was destroyed. The Winchesters need his blood to help stop the Leviathans as the blood of an alpha is one of the ingredients needed for the weapon that can kill them. After learning that the Leviathans intend to wipe out his race and when Sam and Dean save him from Edgar, the Alpha Vampire gives them his blood without a fight.

Season 12

The Raid

As part of their operations in America, the British Men of Letters begin Project V, aimed at exterminating all American vampires. Their operation kills 230 of 241 vampires in the Midwest alone and draws the ire of the Alpha Vampire who considers America his home. In retaliation, the Alpha Vampire leads a raid on the British Men of Letters compound aided by rogue hunter Pierce Moncrieff. Though most of the British operatives are killed, Sam Winchester is at the compound at the time and rallies the survivors. After learning that the British Men of Letters have the Colt, Sam teaches them to make bullets for the legendary gun. Though the Alpha Vampire bluffs that he is one of the five things the gun can't kill, Sam manages to shoot the Alpha Vampire through the head with the Colt with the help of Mary Winchester and Mick Davies, killing the Alpha Vampire.

Season 15

The Trap

A Leviathan in Purgatory reveals to Dean and Castiel that, amongst other things, Eve is seeking revenge for the deaths of the Alphas.

The Heroes' Journey

Dean mentions Alphas as one of the types of creatures the Winchesters have killed.

Powers and Abilities

As the creators of their specific species, each of them are much more powerful because of literally being the very first of their kind.

• Telepathic Link - They possess a telepathic link to all of their children, allowing them to track or communicate with them over enormous distances, literally anywhere on Earth. They can also learn complete knowledge their children possess.
• Super Strength - As the eldest, purest, and most endowed of their respective breeds, alphas possess far superior strength than any common member of their species. Alphas possess immense superhuman strength; and are considerably stronger than humans, animals, lesser demons, hellhounds, all other monsters, and literally all members of their species. Alphas are at least much stronger than any common demon or at most strong enough to push a top-tier Leviathan with one hand and make him stagger back and push it into a wall with enough force to temporarily stun it for a few seconds, though they are not strong enough to defeat a Leviathan on their own. They can hold their own against them briefly. The Alpha Shapeshifter demonstrated strength great enough to kick open a large locked door with ease, easily overpower and kill multiple experienced hunters simultaneously, effortlessly rip apart multiple grown men limb from limb in seconds, easily snap a grown mans neck with a flick of its wrist with only one hand, rip an steel-reinforced iron door off of its hinges with extreme ease, effortlessly overpower and throw Sam Winchester across a room with great force, enough to knock him unconscious for several minutes, and casually lift Dean high into the air by his neck with one hand and strangulate him to near unconsciousness. Like the Alpha Shapeshifter, the Alpha Vampire was strong enough to easily overpower, lift, throw, hurl and slaughter multiple experienced hunters with his bear hands, easily send grown humans flying through the air with his strikes, throw Sam and Dean across a room with great force, easily snap, break and crush bones and snap grown humans necks with a flick of his wrist, effortlessly tear through flesh and rip them apart limb from limb in mere seconds, easily rip out hearts right out of their chest cavity, casually decapitate grown men with a single strike with his bear hands, break apart steel chains and easily bend solid iron bars, and tear apart humans into countless pieces very quickly with extreme ease, along with holding his own momentarily against Edgar, the second most powerful Leviathan. The Alpha Vampire was often seen throwing, tossing and hurling hunters around with just one hand when fighting them and can very easily kill them instantly. He was shown to be much stronger than a common demon, as it took three demons to restrain him even in a weakened state.
• Super Stamina - Their durability and pain thresholds are far superior to the rest of their species.
• Immunity - Alphas are far more resistant or even immune to certain weapons that harm lesser members of their races. For example, the Alpha Shapeshifter is completely immune to silver and the Alpha Vampire demonstrated an tremendously high degree of resilience to dead man's blood though hundreds of gallons weakened him enough for three demons to restrain him. Additionally, the Alpha Shapeshifter was only briefly slowed down by multiple powerful elephant tranquilizer darts (strong enough to instantly knock elephants completely unconcsious with only one tranquilizer dart) and very quickly recovered within less than a minute. The extremely powerful magical weapons, the Anti-Vampire Device and the Vampire Irradiation Gun which releases a very powerful and extremely lethal poisonous gas that will severely poison normal vampires and kill them instantly, would only temporarily slow down and weaken the Alpha Vampire, but he would fully recover in a few minutes. Sam stated that the two potent and lethal supernatural weapons would not kill the Alpha Vampire, and stated that they might only slow him down and weaken him for a short time, but would fully recover within minutes. The Alpha Vampire also can not get burned by direct sunlight, and the Alpha Shapeshifter's eyes do not glare on cameras.
• Immortality - Even if their species is not immortal, the alpha is, provided they are not killed. This is supported by the fact that while shapeshifters are not immortal, the Alpha Shapeshifter did not die until recently, when he was beheaded by Crowley, despite having been alive the last time Eve, the Mother of All, walked the Earth when all alphas were created well over ten thousand years ago. In his own words the Alpha Vampire stated that he has lived through countless centuries of "''rain, fire, ice, and continental divide"'' presumably meaning that he was alive during The Great Flood, mankind discovering fire, the last two ice ages, the extinction of dinosaurs, and the great continental divide, making him around 70 million years old. Dean called the Alpha Vampire "the oldest monster on Earth". and the Alpha Vampire stated that he is extremely old. The alphas are the oldest monsters in existence, the only monsters that predate them is their mother/creator Eve and their ancestors the Leviathans.
• Invulnerability - Silver and extremely powerful tranquilizers caused no harm to the Alpha Shapeshifter with only the very rare metal iridium causing any harm to him. In the case of the Alpha Vampire, he withstood electrocution without an issue, even mocking his torturer and a weapon that can easily poison and instantly kill lesser vampires was noted to only be able to maybe be able to briefly hurt him, but would quickly recover. The only confirmed methods of killing an Alpha are decapitation and the Colt as seen with the Alpha Shapeshifter and the Alpha Vampire respectively.
• High Endurance - The Alpha Vampire was not even phased by being electrocuted and the Alpha Shapeshifter withstood Crowley's torture without much trouble.
• Enhanced Abilities - All skills that are owned by their offspring are owned by alphas on a tremendously higher level.

Weaknesses

• The Colt - It can kill all but five things in all of Creation including the Alphas as seen with the death of the Alpha Vampire.
• Iridium - An iridium blade can be used against any alpha. The metal is one of the rarest elements on Earth.^[1]
• Leviathans - They can kill any kind of monster, including the Alphas.
• Eve - As their mother, Eve can telepathically influence her children, even her firstborns or alphas.
• Horde of Demons - A group of three black-eyed demons was able to capture a badly weakened Alpha vampire, however, an individual ordinary demon is no match for him, having easily overpowered and incapacitated one.
• Decapitation - Used by Crowley to kill the Alpha Shapeshifter. As a vampire, the Alpha Vampire was vulnerable to this weakness as well.

Trivia

• In Bobby Singer's Guide to Hunting, Bobby confirms the existence of the Alpha Wendigo, which implies that they are descendants from Eve. This book is non-canon. However, the fact that Ellsworth was coordinating demons attempting to capture a Wendigo for Crowley in The Man Who Would Be King would suggest that they are indeed related to Eve.
• Through their mother Eve, the Alphas - as well as the descendants of each Alpha - are related to the Leviathans.
• The show has only shown the Alpha Vampire, the Alpha Khan Worm, and Alpha Shapeshifter. While the alpha skinwalker, werewolf, and djinn were mentioned. Other alphas such as the alpha wendigo, ghoul, wraith, and borderwalker are non-canon. The only alpha's whom status is unknown is the alpha arachne and rugaru
