Although there are many kinds of werewolves and every werewolf is unique there are two main types of werewolves. Now I know that you are saying, “not everything can be dividing into two groups” to which I reply, there are two kinds of people in the world, those who think everything can be divided into two groups and those who don’t, but in this case it really is true and one of the most important ways that werewolves are classified is by how they became werewolves.
Did you get bitten by a werewolf or did you inherit the lycanthropy gene from one or both of your parents?
The basic premise of what a bitten werewolf actually is pretty easy to follow.
If you are bitten by a werewolf on the full moon then you will turn into a werewolf on the next full moon and then be forced to transform every lunar cycle for the rest of your life.
Bitten werewolves generally have a much more difficult time controlling their transformations than genetic werewolves do. Both resisting transforming during the full moon as well as attempting to transform at times when the moon is not full are very challenging things and most bitten werewolves spend years trying to master these abilities.
Genetic werewolves are a bit more complex and often harder to identify. The werewolf gene sometimes skips a generation or two so even if neither of your parents is an actual werewolf at least one of them carries a recessive gene that has been passed down your bloodline, possibly for centuries or even millennia.
Genetic werewolves generally have an easier time resisting transforming when the moon is full as well as an easier time initiating a transformation at other times. In spite of the easier time that genetic werewolves have controlling their transformations when they do transform their transformations are just as painful as their bitten werewolf cousins.
