Charon is a character from the animated series Pocket Monsters: Diamond and Pearl, where he serves as a scientist and one of the commanders of the villainous organization Team Galactic. He is a short, elderly man with patches of pointed, lavender-colored hair and brown eyes. His standard attire consists of the grey shirt and black trousers of the Team Galactic uniform, complete with the organization's logo on his chest, which he wears beneath a white lab coat. He is also known for his distinctive red-tinted, round glasses, which contribute to his scholarly but untrustworthy appearance.

His personality is defined by a self-serving and pragmatic nature. Unlike some of the other commanders who may display a degree of loyalty to Team Galactic's leader, Cyrus, Charon is primarily concerned with his own projects and personal gain. He is a shady individual who is willing to make any attempt to reach his goals, but he notably lacks the charisma and trust that the other commanders possess. When a situation turns dangerous or unfavorable, he is quick to abandon his post and flee, prioritizing his own survival above all else.

Charon's primary role within Team Galactic is that of a scientist and researcher. In the anime, his motivations are closely tied to his scientific work and a desire for recognition. He is particularly known for his research on the mysterious Pokémon Rotom, and he seems to covet sole credit for its discovery. While he assists with Team Galactic's larger schemes, such as gathering energy or searching for the mythical Spear Pillar, his actions are often driven by personal ambition rather than a deep commitment to Cyrus's philosophical goal of creating a new universe. He is shown to be skeptical of Cyrus's grand ambitions but sees potential in the dominance Team Galactic could achieve.

Throughout the Diamond and Pearl series, Charon's role in the story is generally supportive of the main Team Galactic plot. He is seen monitoring missions from the organization's headquarters, such as the operation on Iron Island. He later joins Commander Saturn in the search for the Spear Pillar beneath Mount Coronet, where he demonstrates his knowledge by explaining the function of the Spear Key to an undercover Looker. He is also stationed at the Fuego Ironworks to oversee the completion of the Red Chain, a crucial component for controlling the legendary Pokémon Dialga and Palkia, and he boasts about his work to Commander Jupiter.

His key relationships within the organization are primarily professional. He does not appear to have the same level of camaraderie or respect as the other commanders, Mars, Jupiter, and Saturn, who are more devoted to Cyrus. Instead, Charon is depicted as the lowest-ranked commander, and his fellow members do not trust him as easily, viewing him as self-centered. His relationship with Cyrus is one of subordination, but he is more focused on the practical applications of their technology and his own reputation than on Cyrus's ideological vision.

The anime does not provide a significant character arc or development for Charon. His role remains relatively static, serving as a key scientific mind for Team Galactic. He appears intermittently to advance the organization's technological objectives. His final appearance in the series occurs at the Fuego Ironworks, where he warns of intruders before the plot moves on, and he is ultimately left without a clear resolution within the narrative of the Diamond and Pearl series. Information regarding his background before joining Team Galactic, his fate after the events of the series, or any specific Pokémon battles he participated in is not available. His notable abilities lie in his scientific and technical expertise, particularly concerning legendary Pokémon and advanced machinery, rather than in physical combat or traditional Pokémon training.
