Mob Psycho 100 - Characters & Cast

Initially, Mob's motivation is simply to live a normal life and impress his childhood crush, Tsubomi, through self-improvement rather than psychic powers. As the series progresses, his motivation evolves to include protecting his friends and family and helping others understand that psychic abilities do not make them inherently special or superior. His ultimate motivation becomes the desire to accept himself for who he truly is, powers and all.

Mob's arc is a journey from emotional suppression to self-acceptance. In Season 1, he is deeply afraid of his powers and keeps his emotions bottled up to prevent them from exploding. He relies heavily on Reigen's guidance to navigate the world. In Season 2, he begins to form his own identity, making friends and realizing his powers can be used to help people, as seen when he connects with Serizawa. By Season 3, his growth culminates in a final, internal confrontation with his repressed powers (???%). He learns to accept every part of himself, understanding that his powers and emotions are not separate, but integral to his identity. He finally becomes a whole, emotionally expressive individual.

Reigen's primary motivation at the start is money and maintaining his fraudulent business. Over time, this shifts to a powerful, almost paternal, desire to protect Mob and guide him on a righteous path. He becomes motivated by his genuine affection for Mob and a sense of responsibility for the boy's immense power and emotional well-being.

Reigen starts as a comedic con artist, exploiting Mob's powers for his "Spirits and Such Consultation Office." However, his relationship with Mob forces him to grow. While he lies about having powers, the advice he gives Mob is genuinely wise and forms the moral backbone of the series. His arc peaks in Season 2 when his fraudulent career is publicly exposed. This forces him to confront his loneliness and his genuine care for Mob. In the series finale, he drops all pretense and confesses his lies to a rampaging Mob, an act of vulnerability and love that ultimately saves his student, solidifying his transformation from a simple con man to a true mentor and friend.

Dimple's initial motivation is the pursuit of power and godhood. He sees Mob as the perfect vessel to achieve this goal. As he spends more time with Mob and his friends, his motivation becomes more complex. While he never fully loses his desire for influence, it becomes intertwined with a genuine desire to see Mob succeed and protect him from harm, showing that his loneliness was a core driver of his power-hungry ambitions.

Dimple begins as an antagonist, the narcissistic leader of a cult who wants to become a god. After being defeated by Mob, he is reduced to a harmless wisp of a spirit who follows Mob around, constantly trying to manipulate him to regain power. His arc is one of slow-burn redemption. He evolves from a purely self-interested entity to a genuine friend and protector. This is most evident in Season 3, where he achieves god-like power by merging with the Divine Tree but ultimately sacrifices himself to protect Mob, proving he has developed a deep, selfless loyalty.

Ritsu's initial motivation is a desperate desire for psychic power and the recognition he believes it will bring, fueled by his envy of Mob. After he awakens his powers and confronts the consequences of his actions, his motivation shifts to protecting his brother and using his abilities responsibly. He is driven by a newfound love and respect for Mob, wanting to be a supportive brother rather than a rival.

Ritsu starts Season 1 living in his older brother's shadow, both admiring and deeply resenting Mob for his incredible psychic powers while Ritsu himself has none. His jealousy drives him to seek power through unethical means, leading him down a dark path. After awakening his own, weaker powers and being saved by Mob, Ritsu's arc becomes about reconciliation and respect. He moves past his inferiority complex and becomes one of Mob's most stalwart allies, fiercely protective of his brother and understanding the true meaning of strength lies in their bond, not individual power.
