Within the ranks of the Straw Hat Pirates, Roronoa Zoro is one of the most powerful. He is also among the most important characters on Luffy's crew, especially because he is the first to join Luffy on his adventure in One Piece Chapter 6, which was officially released on September 1, 1997, in Shueisha's Weekly Shonen Jump Issue 40.
Since then, Zoro has largely been considered by Oda to be second only to Luffy in the crew and an equal to Sanji. However, as of One Piece Chapter 1193, which was officially released on September 13, 2026, in Shueisha Weekly Shonen Jump Double Issue #42-43, it has now been confirmed that Zoro isn't Luffy's strongest ally anymore. This honor goes to the Accursed Prince Loki, whose new hybrid transformation puts him in a completely different stratosphere when it comes to strength.
Monkey D. Luffy has quite a few powerful allies, but most of them belong to the Straw Hat Pirates. Within the ranks of the Straw Hats, it is quite clear to see that Zoro and Sanji, the two Wings of the Pirate King, stand out the most. These two are considered by Oda to be the left and the right arm of Luffy and are relatively equal in terms of power. Both Zoro and Sanji are strong enough to fight against elite Commanders of a Yonko crew and are most definitely fearsome fighters all over the world.
One Piece chapter 1193 confirmed to us that Luffy's strongest ally is one who doesn't even sail with him on his crew, and that is the Accursed Prince Loki. In One Piece chapter 1193, which was officially released on September 13, 2026, in Shueisha Weekly Shonen Jump Double Issue #42-43, Loki finally decided to unleash his full power. Up until this point, Loki had been saving his strongest transformation, but now that Imu has taken an even stronger form in Elbaf, Loki deems it necessary to go all out. To that end, Loki finally brought out the hybrid form of his Mythical Zoan Ryu Ryu no Mi, Model: Nidhoggr for the very first time.
“The Mythical Zoan Ryu Ryu no Mi...it is said that whoever eats it can transform into the largest dragon in the whole world. The size of the creature is relative to the initial size of whoever ate the fruit. They say this dragon breathes lightning, and when it flies, its jet-black wings turn day into night." — Jarul explains Ryu Ryu no Mi, Model: Nidhhoggr, One Piece Chapter #1175
This transformation began in One Piece chapter 1193, and it sees Loki bring out all of the Black Lightning Dragon in his compact humanoid state, granting him immense firepower capable of destroying the entire world. As things stand, Loki is significantly stronger than Zoro and Sanji put together, so that in itself makes him the strongest ally that Monkey D. Luffy has currently. The two are intent on fighting Imu together and driving him out of Elbaf, but as things stand, it is still an uphill task.
“Dogahaha! Looks like you're at your limit!! I'll be the one to finish him off! You just rest there!" — Loki unleashes his Hybrid Nidhoggr form, One Piece Chapter #1193
The hybrid form of Loki's Ryu Ryu no Mi, Model: Nidhoggr, is definitely very powerful, and that goes without saying. In essence, all Zoan types have a total of three states:
