Resilience is a defining trait of Ashitaka, the film's protagonist. From the beginning, Ashitaka is marked by a curse inflicted by a boar demon, a curse that he must confront head-on. His journey to find a cure leads him into the heart of Iron Town and the ancient forests, where he encounters myriad challenges. Despite the physical pain and societal obstacles, Ashitaka's resilience shines through. In a pivotal scene, he defends Iron Town from an assault, even though it is this very place contributing to the forest's destruction. His ability to endure and adapt, while maintaining his core values, underscores his role as a resilient hero.

Compassion is another cornerstone trait, prominently displayed by both Ashitaka and San. Ashitaka's compassion is evident in his interactions with the people of Iron Town, where he seeks to understand their perspective rather than condemning them outright. This is poignantly illustrated when he risks his life to save two wounded villagers, showcasing his deep empathy. San, the fierce wolf-girl, initially embodies nature's fury but reveals her compassion in her relationship with Ashitaka. In a powerful scene, San tends to Ashitaka's wounds after a battle, despite her initial distrust of humans. This act of kindness highlights her capacity for empathy and her internal struggle to reconcile her dual identity.

Determination drives several characters, notably Lady Eboshi. As the leader of Iron Town, Lady Eboshi is unwavering in her pursuit of industrial progress and the welfare of her people. Her determination is palpable in scenes where she directs the town's efforts to extract resources from the forest, even at the risk of ecological devastation. Her relentless pursuit of the Forest Spirit's head, believed to grant immortality, epitomizes her single-minded focus. This determination, while controversial, underscores her leadership and commitment to her vision of a prosperous future for Iron Town.

Loyalty is a profound trait illustrated by the wolves and their bond with San. Moro, the wolf god, demonstrates unwavering loyalty to her daughter and the forest. This loyalty is evident in scenes where Moro confronts Lady Eboshi, willing to sacrifice herself to protect her home and family. San's loyalty to the wolves and the forest mirrors Moro's devotion, creating a powerful dynamic that drives the conflict forward.

In Princess Mononoke, these character traits are not just attributes but driving forces that shape the narrative and the characters' destinies. Miyazaki masterfully blends these traits, crafting a story that is as emotionally resonant as it is visually stunning. The interplay of resilience, compassion, determination, moral ambiguity, and loyalty creates a rich, multifaceted world where each character’s actions and motivations contribute to the film’s enduring legacy.
