The One Piece series has always fascinated its audience with its enigmatic storyline and characters. The author, Eiichiro Oda, has presented several riddles that have piqued their interest over the years. While some have been resolved, there are still some critical theories that Oda has forgotten to address. Fans eagerly anticipate answers to these long-awaited mysteries as One Piece approaches its endgame.

1. How did Luffy get his Chest Scar?

The main protagonist of One Piece, Monkey D. Luffy, is a fearless yet clumsy fighter who often suffers the consequences of his battles. One of these consequences is his iconic X-shaped “Chest Scar.” The origin of this scar is unclear, as it was seen even before Luffy’s battle with Akanu in the Paramount Arc. While Eiichiro Oda did reveal the story behind the spot in one of the volumes of One Piece, he did so in an SBS after the scar had become famous. Hence, it is safe to presume that Oda forgot to clarify this detail.

2. Where did the Six Forms Fighting Style go?

The Six Forms fighting style is a unique technique in One Piece that defies common sense. It involves bizarre actions like flying and using a finger to cause massive damage. Introduced by the CP9 agency, many strong characters like Garp and Coby have used it. However, since the post-time skip, besides Vergo and Who’s-Who, no one has displayed the Six Forms fighting technique. Even in Wano, no sign of this technique being explained in the future.

3. Why is Sanji not affected by his Flaming foot during the fighting?

Sanji, one of the main characters in One Piece, uses the Diable Jambe technique, which makes his feet flame, and he can kick with increased impact. However, when he learned this technique before the time-skip, he used to blow out the fire by spinning, as it hurt his leg. In the current anime, Sanji uses this technique without any problem. While Oda does not explain this, we can presume that Sanji’s leg has developed a resistance to fire.

4. Why are female character designs drawn so awkwardly?

One Piece has some of the most attractive female characters, but something about their character designs feels awkward. All of the female characters in One Piece have skinny bodies, and the focus is primarily on the chest region. Oda has not provided any explanation for this design choice.

5. Why was Armament Haki not visually shown during the pre-time skip?

Haki is a way of utilizing inner powers to use them differently. It was available even in the early arcs, but different names knew it. Armament Haki was not visualized until Garp smacked Luffy’s head after the Enies Lobby arc. Oda has not explained this missing detail.

6. Why did Robin not reveal Sabo’s living status to Luffy after the time skip?

This question might be the spiciest yet. After the Paramount Arc, the Straw Hats decided to reunite after two years instead of three days. So, everyone starts working hard to grow their abilities for the squad. Robin discovers that Sabo, who everyone thought was dead, is alive and working with the Revolutionary Army. However, she chooses not to reveal this information to Luffy when they reunite after the time skip. Why did she keep it a secret?

It is possible that Robin didn’t want to give away too much information all at once, or maybe she was waiting for the right time to share the news with Luffy. We can only speculate until Oda reveals the answer, or perhaps he forgot about this detail entirely!

After the Paramount Arc, the Straw Hats crew decided to reunite after two years instead of three days. Robin discovered that Sabo, Luffy’s adopted brother, was alive. However, she chose not to reveal his living status to Luffy. Oda has not provided any explanation for this decision.


These six questions are just a few mysteries that have yet to be answered in the One Piece universe. As the series concludes, fans hope Oda will address these lingering questions. But until then, we can only theorize and speculate about what the answers might be.
