There is a legend of a special type of werewolf that is different from an Omega, Beta or Alpha. This werewolf is known as a Beast. The Beast is seen as the source of all known and popular werewolf folklore and is iconized to be ultimate Apex Predator. The most famous story of a Beast is in the legend of Le Bete De Gevaudan. A monster who went on a rampage and slaughtered hundreds of people in France until he was hunted down and killed by his own sister. Another lesser known account of one who reached this rank is The Beast of Wolfsburg. A wolf that became iconized as the guardian spirit for the valley who looked after and protected the people. There have been less than a handful of similar rumors and tales of werewolves that had gone on and become the Beast throughout all recorded history. However, it was thought that these stories were just exaggerations or tall tales and thus most believed the beast's existence to be a mere myth. Yet, recent years have revealed that it is true.
The main thing that sets the Beast apart from other werewolves is their power to shapeshift. While there are werewolves that can change into actual wolves, the form that a Beast takes is something different entirely. The version of wolf that a Beast can transform into is a giant bestial form that can be bipedal as well as quadrupedal. When transformed into this bestial form, this werewolf's strength and abilities would be at their strongest. The form's overall appearance varies on that werewolf's true inner self. Should the person have a wicked and malevolent type of nature then the Beast will have a monstrous form that could be described as almost demonic in its appearance. If the Beast is one who has a good and benevolent type of nature then the form will more closely resemble a wolf though still have somewhat subtle monstrous features.
It is not fully understood how exactly a werewolf becomes a Beast. In my experience, I've only come across two werewolves that achieved this rank. They were Sebastian Valet and Mieczyslaw Stilinski. Interesting to note is the fact that both were made into werewolves by the rarest method, drinking rainwater from a wolf's paw print on nights nearing or during a full moon though it may or may not be a key factor. A possible and personal theory I have for one becoming a Beast is that the werewolf's human nature perfectly resembles a wolf's nature. Werewolves have both a human half as well as a wolf half. Perhaps if the human half's characteristics perfectly match the nature of a wolf then their wolf half may feed and build from that causing it to evolve and make the transition into a Beast possible. Not only that but the human half must not just accept the wolf but embrace and even love it. Wolves are creatures that are renowned for and symbolize the characteristics of high intelligence, powerful instinct, intuition, spirit, loyalty, being territorial, ritualistic and in control of their lives. Before becoming werewolves, Valet and Stilinski possessed these qualities though were on opposing sides of morality. It can be then be theorized that one who naturally has all these traits, whether corrupt or pure, has the potential makings of becoming the Beast.
The Beast has all the common attributes and abilities of other werewolves, however, they also amass multiple additional abilities that are rare even amongst Alphas. One such ability is to tap into 'event scars' and see what has happened at a place or with a person where powerful emotions were experienced or played a key factor in. It has the power to turn humans into werewolves through a bite much like an Alpha however it can only be done in their transformed state and on the night of a full moon. The Beast's bite on this night has a 100% success rate without any chance of death for the one bitten and those who are turned commonly become Evolved Betas and acquire the ability to shapeshift into normal wolves. This could be the origin of the myth of people being bitten and turned into werewolves during the night of the full moon. Yet any other time that a Beast bites someone while transformed will result in a slow and painful death for the one they have bitten in the same manner of one who fatally rejects an Alpha's bite. A Beast's claws are very damaging and difficult to heal amongst other shapeshifters much like an Alpha, even for Alphas. It is seen that a Beast has a stronger degree of resistance and even immunity to certain species of wolfsbane and other toxins. The Beast is also able to pass and break Mountain Ash lines. While other werewolves can only siphon off pain, a Beast has within them the unique power to heal a person by siphoning the damage off and into themselves and experience internal pain, it's strength depending on the severity of the injury, while the injured gets healed.
Beasts have fickle positions in pack hierarchies that can alter and change by choice or very whim. They can assume control and be leaders of a pack or even go on and create their own as like an Alpha. They can go and follow an Alpha's lead and function in a pack the same as any Beta werewolf would. A Beast can also choose to be a lone wolf and act by and for themselves like an Omega though with a far higher chance of survival.
For all the power they wield, the Beast seems to have an interesting weakness to note, the metal Silver. In folklore, silver is fatally lethal to werewolves. This stems from the elite and now extinct family of werewolf hunters, the Argents, which is the french word for silver. Before marrying into the Argent family, Marie Jeanne killed Le Bete de Gevaudan, Sebastian Valet, wielding a silver bladed pike. She used it to pierce his heart and slay him and three hundred years later, it was used again to slay Valet again. Silver, when in a Beast's system, will hinder their healing yet that could be remedied by simply removing it. No doubt, while there would be other ways to slay a Beast but with their strength and power it is very difficult while when silver is used to pierce their heart, they will instantly fall. This most likely created and fed the legend of a silver bullet piercing the heart being the only way to kill a werewolf.
Because of these unique and mighty attributes, the power of the Beast is well sought out after, coveted and feared by many. While it is possible for a Beast's power to be stolen by another werewolf though there is no record of one succeeding in taking the power for themselves.
