Behind his fearful and often comical childlike appearance lies the legitimate heir to the throne of Wano: Momonosuke, son of Kozuki Oden, carries on his young shoulders a burden that few characters in the series have had to bear so early. A look back at a character far more complex than he appears at first glance. Approximately 7 minutes to read.
Who is Momonosuke?
The legitimate heir to the throne of Wano
Momonosuke is the only son of Kozuki Oden and his wife Toki, making him the legitimate heir to the throne of Wano, usurped by Kurozumi Orochi for most of the arc. A status that weighs heavily on a character still portrayed as a child for much of the story.
A deliberate contrast between status and appearance
This contrast between his dynastic importance and his often fearful, almost comical behavior is one of the character's most interesting writing devices, reminding us that even future great leaders sometimes begin as mere children frightened by the world around them.

A child propelled twenty years into the future
A journey through time to escape the massacre
Thanks to his mother Toki's power, Momonosuke is sent twenty years into the future with his sister Hiyori, escaping the massacre orchestrated by Orochi and Kaido against the Kozuki clan. A mother's sacrifice that explains why, chronologically, he finds himself at a very specific point in history: the moment when his father's promised return finally becomes possible.
Still a child despite twenty years having passed
Despite this two-decade leap through time, Momonosuke remains physically a child, as his body did not age during the journey. This situation further highlights the gap between his apparent age and the magnitude of the mission awaiting him.
Did you know?
Toki's Devil Fruit, capable of sending people into the future, remains one of the rarest and most strategically decisive powers ever shown in the series.
The dragon within him
A mythical Zoan fruit worthy of his legacy
Momonosuke possesses a mythical Zoan Devil Fruit that allows him to transform into an eastern dragon, a creature long associated with wisdom and power in the Japanese imagination that inspires the entire Wano arc.
A decisive role in the final battle
It is in this dragon form that Momonosuke provides decisive assistance during the final confrontation against Kaido, carrying Luffy through the air at the most critical moment of the battle. A spectacular turnaround for a character long presented as someone to protect rather than a combat asset.

An immense weight on such young shoulders
Momonosuke's journey perfectly illustrates one of the central themes of the entire Wano arc: inheritance, the weight of family expectations, and the difficulty of becoming worthy of a father as admired as Kozuki Oden. A burden that few characters so young have had to bear throughout the series.
