Grand Chamberlain holds a high-ranking administrative position in the royal court of Hookland. He shoulders significant responsibilities managing court affairs and providing support to the royal family, specifically Duke Fastener and Prince Flower. His duties demand strict maintenance of order and protocol across the kingdom's operations.

He possesses a deep personal history with Duke Fastener, forged during their childhood friendship. This bond also extends to Martha, mother of Clip, anchoring him within Hookland's social structure. In their youth, he participated in adventurous escapades alongside Fastener and Martha, hinting at a spirited past distinct from his current formal role.

Throughout the series, he engages frequently with Button Nose and Prince Flower. He exhibits a tendency to be swayed by Button Nose's actions, often finding himself accommodating her initiatives even when they disrupt court protocol. He assists Button Nose and Prince Flower during various incidents and adventures, sometimes participating directly.

His background as a childhood companion to key figures and his ongoing involvement in the younger characters' activities reveal a continuity of his adventurous nature beneath his official demeanor. He maintains a consistent presence in the court's daily functions.

In the English dub by Saban Entertainment, the character is named Malcolm, a detail absent from the original Japanese version. His administrative functions and relational dynamics remain consistent across adaptations.
