{{bettas|size: large; margin-left: 10px; float: right}}Betas are the standard canine shapeshifter, the middle rank between [[alphas]] and [[omegas]]. In a pack, most of the members will be betas, with the leader typically being an alpha. A beta's eyes will glow [[werewolf eye colors|gold or blue]].

Supernatural rules

A werecreature is classified as a beta simply by being an accepted member of a pack. They maintain a mystical symbiotic bond with their packmates, thus becoming more powerful and mature as were-creatures. Though the rules of pack membership in the show appear flexible and are ill-defined, a werecreature could count as a beta simply by mutual and accepting association with an alpha or another experienced beta.

Betas can be born to werewolf parents. [[Derek Hale]], and his sisters, [[Laura Hale|Laura]] and [[Cora Hale|Cora]] all inherited the werewolf trait from their mother [[Talia Hale|Talia]].

They can also be formerly humans who have been [[Alphas+The Bite|bitten by an alpha]]. In Season 1, [[Scott McCall]] became a beta werewolf right after being bitten by [[Peter Hale]]. Out of necessity and convenience, Scott and Derek formed a tenuous alliance to stop Peter and so they were classified as betas.

{{EvolvedBeta|size: medium; margin-top: 5px; margin-right: 10px; float: left}}Shapeshifting-wise, betas commonly manifest their werewolf side through physical transformations such as [[Werewolf+claws|claws]], [[Werewolf+fangs|fangs]], altered facial bone structure, and increased hair on their face.

Like Alphas, they are able to fully transform their bodies further into more anthropomorphic shapes and such as a full wolf as in the case of [[Derek Hale]]. However, this is harder, more challenging for them to accomplish because they lack the spark of power an alpha possesses that supplements the ability to do so.

The ill-defined rules of pack membership not withstanding, if a beta were to dissassociate, cut themselves off from a pack, whether by choice or as punishment, or conspiring events, their ability, power and control would accordingly diminish. They would then be classified as [[omegas]].
