Kamille Bidan enters the story of Mobile Suit Gundam ZZ in a greatly diminished state, a direct consequence of the traumatic conclusion of the Gryps War. Having overexerted his powerful Newtype abilities in his final battle against Paptimus Scirocco, he was left with his mind shattered, a condition often described as a psychotic or near-vegetative state. As the sequel begins, Kamille is no longer the protagonist but a supporting figure, primarily confined to a bed on the ship Argama, where he is cared for by his longtime friend and fellow pilot, Fa Yuiry.

Despite his incapacitated physical condition, Kamille’s role in the story is far from passive. His consciousness, though fractured, remains a potent force. He becomes a spiritual guide and mentor to the new protagonist, Judau Ashta, and the other young refugees of Shangri-La who come to pilot the Argama’s mobile suits. Kamille often appears to Judau in visions or communicates with him telepathically, offering crucial advice and guidance when the young pilot faces overwhelming odds. This ethereal mentorship underscores his profound abilities, as he remains connected to the world around him and senses the dangers his friends face, even from his near-catatonic state.

His personality traits from Mobile Suit Zeta Gundam, which included a notable temper, a strong dislike of his feminine-sounding name, and a deep-seated passion for justice, are largely subdued during this period as he cannot actively participate in the conflict. However, the core of his character—a compassionate and principled young man who despises war and its pointless suffering—remains intact, expressed now not through action but through the silent, powerful support he lends to others. His key relationships continue to define him, with the unwavering dedication of Fa Yuiry being a central element of his storyline. Her decision to stay by his side and nurse him back to health is a testament to their bond.

Kamille’s development in Gundam ZZ is one of gradual, hard-won recovery. While earlier in the series his body remains unresponsive, his mind slowly heals. By the end of the First Neo-Zeon War, his recovery is nearly complete. In the final episodes, he is shown to have regained his mental faculties, appearing alongside Fa, no longer needing her constant care. This restoration not only provides a hopeful resolution to his personal arc but also serves as a crucial thematic anchor for the series. In a final, decisive act, a recovered Kamille uses his immense Newtype power to assist Judau, lending him the strength and spiritual energy needed to overcome the final threat, Haman Karn. His return to health represents a belief in the possibility of healing and a future beyond the trauma of endless battle.

Regarding his notable abilities, Kamille is consistently portrayed as possessing incredibly powerful Newtype potential, with some sources describing him as having the strongest abilities of his era. In Gundam ZZ, this power is showcased not through piloting his iconic Zeta Gundam, but through pure mental feats. He demonstrates advanced telepathy by communicating across distances, clairvoyance by sensing future events like a colony drop, and the ability to project his consciousness to guide other pilots. The pinnacle of his power in this series is his ability to channel the souls and spiritual energy of his fallen comrades to empower Judau Ashta, allowing the young pilot to achieve a victory that would have otherwise been impossible. Through this, Kamille completes his journey, not as a frontline soldier but as a guardian and a symbol of resilience.
