Kojirou operates as a core member of Team Rocket alongside Jessie and Meowth, relentlessly pursuing rare Pokémon—especially Ash Ketchum's Pikachu—to advance the organization's criminal aims. His past stems from an oppressive, sheltered childhood defined by extreme wealth, rigid societal expectations, and parental neglect. A pivotal engagement to the domineering Jessebelle subjected him to physical punishments within a dedicated torture room, forging profound fear and resentment. This drove his rejection of privilege, leading him to flee home and embrace the hardships of Team Rocket life, choosing freedom over comfort. Physically, Kojirou possesses shoulder-length lavender hair and green eyes. His signature attire is the Team Rocket uniform: a white long-sleeved shirt bearing a prominent red "R" emblem, layered over a black undershirt, paired with white pants secured by a purple belt, black gloves, and matching boots. He frequently employs disguises in missions, including cross-dressing appearances from the Diamond and Pearl series onward, a pale yellow air military jumpsuit for PokéRinger competitions, swimwear for leisure, and formal dark blue suits for undercover work. His uniform briefly shifted to charcoal gray in the Unova region, marking his promotion to Advanced Agent status. Personality-wise, Kojirou initially displayed a calm, serious demeanor during Team Rocket motto recitals, though this softened over time. He exhibits a stronger moral conscience than his teammates, occasionally forming temporary truces with Ash and friends, often to conceal his criminal identity from respected loved ones like his grandparents. Emotional sensitivity defines him: intense fear regarding his family history, depression after failures, and a childlike enthusiasm for hobbies like collecting rare bottle caps—a passion originating in youth that sometimes leads to gullibility, such as repeated dealings with unscrupulous Magikarp salesmen. Despite this, he demonstrates notable intelligence as a skilled hacker and engineer capable of building sophisticated robots. His compassion extends unusually for a Team Rocket member, treating Pokémon with kindness and forming genuine bonds with his own team. During the events of the fourth Pokémon film, Kojirou and his companions encountered the Iron-Masked Marauder, a high-ranking, ruthlessly ambitious Team Rocket operative. Fatigued and sharing organizational ties, they briefly allied with the Marauder in his pursuit of the mythical time-traveling Pokémon Celebi, accompanying him in his spider-legged vehicle. This partnership dissolved abruptly when the Marauder, intensely focused on the chase, failed to notice them falling from the vehicle. Later, they witnessed the Marauder's extreme cruelty firsthand: the brutal electrocution and corruption of Celebi using specialized Dark Balls, and his declaration of intent to overthrow Giovanni and dominate Team Rocket and the world. These actions horrified Kojirou and his teammates, starkly revealing the Marauder's depravity even by Team Rocket standards and contrasting with Kojirou's own occasional moral qualms.
