TV Special
Description
Buyoyon originates as a super lifeform from super spacetime. His amorphous, gelatinous body typically appears yellow in the original manga and 2024 anime, but greenish in the 1989 anime adaptation. This unusual form often leads to him being mistaken for a jellyfish monster or horse dung. He levitates freely and lacks conventional anatomy like teeth, yet consumes food without issue.

Proud of his supernatural origins, Buyoyon exhibits a bossy personality. He habitually adds "dearu" to his speech for formal effect. Animals generally react fearfully to him, resulting in mutual avoidance, and he holds a specific aversion to carnivores due to predation risks. Despite this, he cooperates with Time Patrol officers, leading to unofficial membership where headquarters permits his accompaniment on missions. He memorizes Time Patrol regulations, though the method remains unclear given his non-human physiology.

His abilities include time travel, invisibility, understanding and speaking multiple human languages, potential physical immortality, and inhabiting time holes. His unique anatomy makes him the only major character avoiding physical death during missions. Tactically, he disrupts targets by adhering to their faces to obstruct vision. A notable biological function involves his urine serving as a powerful fire extinguisher.

Relationships center on Time Patrol agents. He partners with Ream Stream, self-identifying as her mission companion after an unspecified past encounter. Interactions with Bon Namihira involve sarcasm; their partnership dissolves after Bon's trainee promotion in the manga due to serialization cancellation, while anime adaptations retain their collaboration alongside Yumiko Yasukawa, whom he meets only in animated versions.

Background details remain unspecified, including whether others of his species exist. His narrative presence varies: he departs the manga early but continues through both anime adaptations. A 2024 video game features his cameo. His name translates to "flabby" in Japanese. He exemplifies non-human Time Patrol participants alongside characters like Luffin, represents Fujiko F. Fujio's "SF" theme through mysterious, unrealistic traits, and remains a rare non-mammalian mascot in the creator's works.
