Alpha Werewolf

Shapechanger. The werewolf can use its action to polymorph into a wolf-humanoid hybrid or into a wolf, or back into its true form, which is humanoid. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Keen Hearing and Smell. The werewolf has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Pack Tactics. The wolf has Advantage on an attack roll against a creature if at least one of the wolf’s allies is within 5 feet of the creature and the ally doesn’t have the Incapacitated condition.

Legendary Resistance (3/Day). If the werewolf fails a saving throw, it can choose to succeed instead.

Multiattack. The werewolf can use its Frightful Presence. It then makes three attacks: one with its bite and two with its claws.

Frightful Presence. Each creature of the werewolf's choice that is within 120 feet of the dragon and aware of it must succeed on a DC 16 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the werewolf's Frightful Presence for the next 24 hours.
