Charon serves as the most junior of Team Galactic's four Commanders, identifiable by his mauve hair, brown eyes, and red-tinted round glasses. He wears the standard Galactic uniform—a grey shirt and black trousers—topped with a lab coat, reflecting his scientific role. In Pokémon Platinum, Charon first appears with Commander Mars at Valley Windworks, aiding energy collection. His research notes in Rotom's Room detail Rotom's ability to inhabit appliances, revealing his self-serving motive to claim sole credit for this discovery. He later operates at the Veilstone HQ, expressing skepticism about Cyrus's ambitions while seeing potential benefits in Galactic's dominance. After Cyrus vanishes post-Mt. Coronet, Charon seizes control. He leads Mars and Jupiter to Stark Mountain to capture Heatran using the Magma Stone, aiming to extort wealth by manipulating volcanoes instead of pursuing Cyrus's ideals. Mars and Jupiter abandon him during the confrontation, and Looker arrests him. In the Diamond & Pearl anime, Charon monitors the Iron Island mission from HQ and later joins Saturn searching for the Spear Pillar beneath Mt. Coronet. He reveals the Spear Key's function to Looker (disguised as a Grunt) and shows annoyance when Team Rocket tries stealing it. After locating the ruins, he operates the key, though it fails. Stationed at Fuego Ironworks to finalize the Red Chain, he boasts to Jupiter about his work. His last appearance occurs during an alert about intruders at the Ironworks before vanishing unresolved. In the Pokémon Diamond and Pearl Adventure! manga, Charon ascends from scientist to Neo Team Galactic's self-proclaimed leader after Cyrus's defeat. He schemes to capture legendary Pokémon like Heatran and Giratina, manipulating Buck into obtaining the Magma Stone. He uses Heatran to attack Diamond and Pearl, resulting in Diamond's apparent death, attempts to recruit Diamond's Regigigas, and mocks Pearl over the loss. His ambitions escalate to controlling multiple legendaries, including Darkrai, leading to a large-scale battle at Spear Pillar. After Rotom destroys his machine, he is confronted by Cyrus and the other Commanders. Cyrus disbands Team Galactic, and Looker arrests Charon as the only unredeemed commander. Across all portrayals, Charon exhibits a pragmatic, self-serving personality, prioritizing personal profit in the games and demonstrating ruthless willingness to endanger lives for power in the manga. His scientific expertise, particularly concerning Rotom, remains consistent.
