One Piece’sWano Country arc saw nearly every member of the Straw Hat Pirates engage in massive fights, perhaps for the first time since the story’s Enies Lobby arc. With the Straw Hat Pirates clashing against the King of Beasts and his crew, it was somewhat inevitable that they’d take the next big step and rise to the occasion with some incredible new powers.

As such, nearly every member of the Straw Hat crew who engaged in major fights received some sort of power-up in the midst of battle, which made them all the more exciting. Though there are plenty to choose from, these are the best of the newOne Piecepower-ups introduced throughout the Wano Country arc.

8Zeus

Zeus was one of the homies of Big Mom and was stolen from her by none other than Nami. In the Wano Country arc, Big Mom took him back from Nami but eventually discarded him. Somehow, Zeus fused with Nami’s climatact and ended up as a major source of power for her.

Using Zeus' powers, Nami was able to take Ulti on in battle and even defeat her as well. This was incredibly impressive in its own right, but more so given that she had a 400 million berries bounty on her head.

7Demonio Fleur

The Wano Country arc saw Nico Robin involved in her first serious fight in the story since the two-year timeskip. She clashed against Black Maria of the Tobi Roppo of the Beasts Pirates.

To combat the power of the Kumo Kumo no Mi, Model: Rosamygale Grauvogeli, Robin needed much greater strength than what she had and ended up tapping into a power called Demonio Fleur. This form gave her tremendous strength and the ability to crush even Black Maria, who was worth 480 million berries.

6Jiki Jiki no Mi Awakening

Eustass Kid took on Big Momwith the help of Trafalgar Law after the fight on the rooftop of Onigashima. Just like the majority of the major players in the war, he ended up getting a huge power-up. Kid awakened his Devil Fruit, called the Jiki Jiki no Mi, and, with its powers, he gained the ability to turn anyone around him into a magnet.

Using his awakening, he could injure Big Mom with techniques such as Punk Clash. Strangely enough, though, Kid’s strongest technique, which saw him create a Railgun, didn’t actually see him use his awakening.

5Ifrit Jambe

Sanji finally got his first major fight after the two-year timeskip during the Wano Country arcwhen he fought against Queen the Plagueof the Beasts Pirates. During the fight, he started to awaken his dormant genetic modifications.

Thanks to that and his Armament Haki, he could produce even hotter flames with electricity, thus giving rise to Ifrit Jambe. Using its powers, he was able to finish Queen off in just a few blows with minimal difficulty which just goes to show how great this power truly was.

4Ope Ope no Mi Awakening

TrafalgarLaw awakened the powers of his Ope Ope no Mi Devil Fruitduring the Wano Country arc when he fought against Big Mom. Without a doubt, the awakening of this ability makes him incredibly powerful and gives him the skill to seriously injure even someone as strong as a Yonko.

With its awakening, Law could cause even greater internal damage with techniques such as Shock Wille. His ultimate technique, called Puncture Wille, was powerful enough to create a hole in the land of Wano itself. Trafalgar Law is undoubtedly one of the strongest characters in One Piece following this power-up of his.

3Ryuo

Ryuo is, simply put, another name for Haki in the land of Wano. However, the power is quite different when it comes to application in comparison to regular Haki. With Ryuo, the user can make the usage of Haki much more efficient by focusing on the concept of flow.

This power can also be used from a distance, allowing the user to hurt others without making physical contact with them. The advanced version of Ryuo allows them to send their Haki directly into the body of the target and damage them from the inside out.

2Advanced Conqueror’s Haki

One Piece’s Wano Country arc also focused heavily on Conqueror’s Haki. This power was fleshed out during the Onigashima Raid when Luffy fought against Kaido. It was revealed to the fans that Conqueror’s Haki can be used to coat the body of the user in a manner similar to Armament Haki for both offense and defense.

Luffy developed this skill greatly to take down Kaido in the arc. At the same time,Roronoa Zoro also awakened this powerthanks to Enma, and, upon doing so, defeated King the Wildfire of the Beasts Pirates. Advanced Conqueror’s Haki is said to be one of the very greatest powers to exist in the world ofOne Piece.

1Gear Fifth

Perhapsthe greatest power to be introduced in the Wano Country arcwas Luffy’s Gear Fifth. After losing to Kaido and nearly dying, Luffy’s Devil Fruit managed to awaken, giving him access to a unique transformation called Gear Fifth. This form is Luffy at his very peak as a fighter and gives him even greater strength, and, on top of that, immense freedom as a fighter that is only limited by his imagination.

Using Gear Fifth, Luffy was able to fight Kaido toe-to-toe in an incredible battle. What’s more, his techniques became much more dangerous as well. His strongest attack, called Gomu Gomu no Bajrang Gun, saw him create an island-sized fist and crush Kaido with it. Undoubtedly, Gear Fifth is the strongest power to be introduced in the Wano Country arc.
