The werewolf theme is one that literature has used quire liberally for some time now. Going back to Bram's Dracula and further, the character has been used as a symbol of primal nature and raw, unfiltered emotion. As such, it is no surprise that the werewolf is commonly used to help portray the adolescent fear of transforming into adults and heading into the unknown. In the film I was a Teenage Werewolf, the main character of tony goes through one of these very transformations, centralizing the narrative on a young man who couldn't seem to grasp a fine control on his emotions, mimicking the interactions of testosterone in adolescent men.
The physical changes and perverse changes that the protagonist undergoes symbolize his own psyche and personal fears in regard to the upcoming horizon, and had less to do with any famed monsters. Looking at other members of the same thematic grouping, we have short stories like the Werewolf's Daughter where the character of would is used yet again to transforming nature of this character and bring about the "adult" from the youngest daughter. Yet again, the werewolf character acts to bring about changes in the characters that reflect a sort of "shedding of old skin", leading to becoming a new entity. Some fear this change, and end up like Tony while other, like the youngest daughter from the Werewolf's Daughter embrace the change.
