Article summary:
At 90 years old, Brook is the oldest member of the Straw Hat crew. Thanks to the Yomi Yomi no Mi (Revive-Revive Fruit), he returned from the dead after wandering for a year as a soul. Today, he is a living skeleton gifted with spectral powers. But has he become immortal because of it? In 2026, let’s analyze the strange biology of the Soul King.
Brook is an anomaly in the world of One Piece. He knew the era of Gol D. Roger as a rookie, and today he sails with the future Pirate King, Luffy. His fruit gave him a second chance, but what are its limits?
Yohohoho! The music of the Other World echoes.
How Does the Resurrection Work?
The Yomi Yomi no Mi is a very special Paramecia-type fruit. It grants no powers to its user while alive (apart from making them unable to swim). The fruit only activates upon death.
Brook’s soul returned from the realm of the dead (Yomi), but because of the fog in the Florian Triangle, it took him a year to find his body... which was nothing more than a pile of bones. That explains his appearance. It is the power of his soul that moves his bones, not his muscles (which he no longer has!).

The Soul King’s Awakening: The Cold of Hell
After the time skip, Brook discovered the true nature of his power. He does not merely “live”—he controls his soul. He can:
- Leave his body to spy (astral form).
- Summon the cold of the realm of the dead to freeze his enemies (Soul Solid).
- Affect weak souls, making him Big Mom’s natural counter.
During the Whole Cake Island arc, he managed to injure Emperor Big Mom’s “Homies” (see: Who Are the Yonko?), proving that he is one of the most underrated members.

Can He Die Again?
The answer is yes, but it is difficult. Brook cannot die of old age or illness (he has no organs). He can even survive decapitation, as long as his bones are not pulverized.
However, he can die if:
- His skeleton is completely destroyed.
- He drowns (seawater nullifies his energy).
- His soul is consumed or destroyed by a superior fruit.
He lives to keep his promise to Laboon, the whale that has been waiting for him for 50 years. A moving story told on our page about the history of the crew members.
Conclusion: An Eternal Life of Solitude?
Brook fears outliving his new friends just as he outlived his former crew. But for now, he is using his “second life” to help Joy Boy change the world.
