Luffy is the captain of the Straw Hat Pirates in One Piece. He embarked on his journey at the age of 17 and led a dedicated crew determined to help him achieve his goal of becoming the Pirate King. Luffy is known for his unwavering support and care for his crew members, assisting them in pursuit of their own dreams.
The same level of loyalty and dedication is reciprocated by his crew members, who are willing to go to great lengths to safeguard their captain. Among them, the swordsman Zoro stands out as one of the most loyal and devoted individuals to Luffy’s cause. Zoro’s commitment was particularly evident during the Marineford Arc when he absorbed all of Luffy’s pain to ensure his captain’s survival, despite having numerous injuries himself.

In the One Piece anime, the long-awaited moment arrived when Luffy unlocked Gear 5, a formidable transformation. However, fans have developed a theory that utilizing these new abilities may come at a cost to Luffy’s life force, potentially reducing his lifespan. While Luffy isn’t in immediate danger of dying, there’s speculation that one character will ultimately make a sacrifice to ensure Luffy’s journey to become the Pirate King. Surprisingly, this character is not Zoro.
One Piece Fan Theory: Law’s Sacrifice For Luffy at Mary Geoise
This fan theory suggests that after Luffy’s intense battle with Kaido, he’ll become very weak because he’s been gradually using up his life force during his entire journey. He’ll try to hide his weakness at first, but it will catch up to him.
In the final arc of the story, Luffy will engage in a significant battle at Mary Geoise, where he will ultimately meet his end due to his depleted life force.

During this critical moment, Trafalgar D. Law will make an ultimate sacrifice to save Luffy. This theory is based on the idea that everything Eiichiro Oda introduces in the story serves a purpose, and Luffy’s life force depletion has been hinted at since his early use of Gear 2, connecting it to his heartbeats and life expectancy.

Gear 5 Clue – Luffy’s Deteriorating Health?
One major clue supporting the theory is Luffy’s use of Gear 5 in One Piece Chapter 1045. When it deactivates, Luffy appears drained and ages quickly.
This might be a joke, given the cartoonish nature of Gear 5, or it could hint at the harm it causes to his body. It’s like how Gear 2 stresses his heart, suggesting future consequences.
