Werewolves

Werewolves are human-like supernatural beings of animalistic strength and instinct, they are also known as lycanthropes, children of the moon, children of Fenrir or simply referred to as "Wolves". Werewolves are one of the most common type of shapeshifter and unlike common belief werewolves don't just have to shift on the full moon but they do get their powers from the moon and when the moon is full they can loose control and be forced to shift into their monstrous wolf form. However over time werewolves learn to control the shift and can even use the full moon's rush of power to their advantage.

Werewolves can access their power at anytime however they are more powerful when there is more moon showing in the sky such as a crescent moon will give them less power than a half moon , they don't haft to be in moonlight for this to effect them as their is an unbound magical connection wolves and the moon share.

Werewolves are the most common but not the only "were" that exists as they're are many different kinds of shape shifters.

Becoming a werewolf
Their are two different ways someone can become a werewolf normally they go by "born" or "bitten" means you are either born a werewolf through one or both of their parents where werewolves or they where bitten or scratched by a werewolf becoming infected by their transformative magical venom. Born werewolves have better control over there primal urges however this does not mean that they are any stronger.

three (four) different werewolf places and pack mentality.
The three main types of werewolves are omega , beta and Alpha, Alpha's are the leaders of the pack and therefore retain the most authority and make the decisions however some packs are more diplomatic than others and have communal decisions. Beta's are the pack members who serve under the alpha and make up the majority of the pack, the next is omegas which name can sometimes be considered two different things, the first is the name for lone wolves who are either exiled or chose to leave a pack however omega can also be a term used for the lowest level of authority of a pack given to newly turned werewolves who haven't gained enough power or clarity yet to have authority in the pack.

Lastly their is the gamma wolves , these werewolves are not counted specifically with other werewolves as they are werewolves who gain powers from witches , who bare enchanted runic marks placed upon their body which increase there powers and abilities as well as sometimes making their eyes glow white to symbolise their increased connection to the moon however this can be optional. These enchanted werewolves tend to serve or make alliances with witches as only witches can apply these magical symbols upon werewolves.

Powers and abilities:
Werewolves are supernatural beings and like all supernaturals they have special traits which have be granted to them.

Super human strength: Werewolves have incredible strength enough to over power humans and many other supernatural creatures, on average the strength of a human triples when they become a werewolf when in human form but exceed even that when shifted.
Super human speed: Werewolves can run faster and further than humans surpassing the speed of the worlds top Olympic athletes.
Super human endurance: Werewolves don't get tired out as much as humans so they can run, fight and do other physical activities without getting tired as quickly, however they can eventually tire but it can take awhile, they can also take more physical damage than humans able to withstand multiple bullets and knife wounds.
Super senses: The senses of a werewolf is far more heightened that humans especially there hearing and sense of smell which are greater than that of actual wolves.
Super healing: Werewolves can heal at a supernatural rate giving them the ability to survive injuries which could be fatal to humans also this makes werewolves immune to most diseases and becoming a werewolf can cure natural disabilities.
Luna empowerment: On the full moon they're physical abilities are increased and as long as they don't lose control they are much more efficient and powerful beings during this time.
Longevity: Through there supernatural healing werewolves tend to live longer than humans , there healing also slows down their ageing process so they look younger for longer.
Shared power: When in a pack wolves gain shared power, causing werewolves strength, speed and vitality to enhance beyond that of a lone wolf.
Pack empathy: Werewolves can sense other members of their pack's emotions, health and pain.
Wolf shifting: Werewolves can shape shift into powerful large wolf-human hybrid monsters that have burning blue eyes. This transformation increases their physical capabilities and senses as well as arms them with powerful fangs and claws. They can also access these traits without fully transforming such as only using their claws, fangs or eyes.  
Magical venom: Werewolves claws and fangs secrete an enchanted venom which can transform humans into lycanthropes. However their venom is also a weapon as it makes any wounds they inflict onto other supernaturals using their claws or fangs heal slower than usual wounds despite supernatural healing factors.
Animal Communicate: Werewolves have the gift to communicate and slightly control primal animals.
Energy healing: Werewolves are capable of channeling the energy that heals themselves into others increasing that persons healing capabilities. It is easier for them to heal other members of their pack although their powers will still heal humans, living supernaturals and lone wolves.

Special wolf powers:
These are powers are what only specific werewolves have who are considered gifted amongst the werewolf community. 

Moon enlightenment: Werewolves with this ability are referred to as "moonlighters" and are similar to both mediums or seers, moonlighters are believed to have a stronger connection to the moon spirit than most and through this they are able to communicate with spirits and ghosts, project themselves into the spirit world and can sense power, emotion and magical energy. It's believed through a ritual on every full moon a moon lighter can see visions of the past, present and future. They're psychic powers are both treasured and feared by packs.

Gamma werewolf powers:
These are powers which could be given to werewolves by witches through gaining runic marks.

Enchanted strength: No matter the werewolf before the enchantment once the werewolf had been enchanted they will have strength much greater than that of other werewolves, the amount of which varies.
Complete control: They will no longer be forced to turn on the full moon if they haven't gained control. This however can be a weakness as werewolves tend rely on the marks and if removed can't handle the full force of the moon.
Magical power: Witches could have given the wolf some magical power such as making a werewolf fire proof, giving them metallic claws or granting them power over earth. This can vary depending on the enchantment however the amount of magic they place into the werewolf is somewhat limited as control over magic is not in a werwolf's nature.

Weaknesses:
While quite formidable and difficult to harm due to there impressive healing capabilities werewolves can be still be hurt, weakened and killed.

Mortality: Even though werewolves can live longer than humans they will eventually die over time and can be killed by mortal weapons however it should be noted that werewolves are more endurant that humans and can heal from a lot of mortal injuries.
Wolfsbane: The effects of Wolfsbane vary depending on the type, amount and delivery method. It can cause hallucinations, weaken, render unconscious, trap or kill werewolves.
Luna eclipse: Werewolves are powerless during a total lunar eclipse.
Silver: This metal is toxic to werewolves burning them to the touch as if was superheated. Wounds inflicted by silver also takes longer to heal than usual wounds
Lack of control: Werewolves, especially newer ones, loose control on the full moon and even have high inner rage that is connected to their heart beat. This however can be controlled and is usually more of a problem for younger, newer, less experienced werewolves.
