Gods and Monsters Werewolf
Regular werewolves: Turn into a werewolf only at night. People affected by the disease have short-term memory loss, often leaving them confusion of wounds which might have been caused during the night. Despite having no control over their transformation, certain fragments of their personality and fears can be imbibed by the werewolf's mind, especially strong ones. Aside from hunger, suppressed fears or aggression can drive them to kill in beast form. As such, a werewolf's attack may be controlled by these emotions, depending on which one is dominant.
Pureblood werewolves: Werewolves that are closer to the alpha up to the fourth generation are referred to as pureblood. They have more control over themselves and are less feral. Their human side retains a lot of control and they remember what happened after their transformation.They can transform anytime they want.Purebloods can also access some of their werewolf powers such as enhanced strength and speed while in human form.
