Written by In One Piece, ninjas are not just silent fighters hiding in the shadows. They are clever, quick, and often use tricks that can turn a fight in seconds.
The Wano arc finally showed how dangerous these fighters can be. From Orochi Castle to the chaos of Onigashima, these ninjas proved that stealth and smart moves can be just as deadly as raw power.

9. Hanzo Defies His Size With Hidden Agility

Even though Hanzo appears to be very large in size, he is unbelievably flexible. He possesses the ability called “Floating,” which allows him to crawl quietly on the ceiling. He managed to trap a fake version of Nico Robin using a rope, but his luck eventually ran out. Being hidden in the attic, he insulted kunoichi Shinobu by saying that she was ugly. In response, Shinobu threw a weapon straight into his groin and broke the floorboards, sending the giant ninja crashing down below.
8. Fujin Traps Enemies With Slimy Grappling Skills

Fujin is a powerful ninja and fights with a fighting style known as “Slimy Grappling.” He is renowned for riding on a gigantic catfish that can travel over the ground. Although he is great at sneaking up on enemies, he has a massive weakness in that he is extremely afraid of ghosts. Upon seeing Brook in his ghostly form, he freaked out and ran away.
7. Raijin Backs Up His Stealth With Deadly Shuriken

Raijin fights just like his partner Fujin, using “Slimy Grappling” while riding his own land-catfish. However, Raijin adds sharp throwing stars (shuriken) to his attacks, which he threw at Nico Robin inside the castle. Like Fujin, he ran away in pure terror when he saw Brook’s spirit. He was later stopped in his tracks during a battle in Rasetsu Town when Zoro attacked him.
6. Yazaemon Kills Targets From a Safe Distance

Yazaemon is a master of staying completely silent. He keeps his face wrapped in bandages and perpetually hunched over the ground to hide his presence. He used his perfect stealth to help ambush Nico Robin without making a sound. His official ninja specialty is “Arrow,” a skill he used to fight against the rebels during the giant war on Onigashima.
5. Daikoku Moves Fast and Tanks Heavy Attacks

Daikoku is a massive man with bright red hair and bull horns, but he can still move fast while staying completely unseen. He acts as a key leader for the Oniwabanshu ninjas, commanding them during battles. He is incredibly tough and famously shook off a direct hit from Robin’s giant, magical arms, getting right back up to keep fighting.
4. Jigoku Benten Hides a Gun Inside Her Music

Jigoku Benten hides a deadly firearm inside the musical lute (biwa) she carries. By plucking the strings, she unleashes her “Silent Gun” technique to shoot fast bursts of bullets at her targets. She used her quiet movements to ambush Robin in the castle, though powerful fighters can still dodge her; Zoro successfully avoided her gunfire during a battle in the city.
3. Shinobu Wields Age-Altering and Rotting Ninjutsu

Shinobu is a veteran kunoichi who uses the Ripe-Ripe Fruit to instantly rot objects or magically age people. She easily defeated the giant Hanzo by hitting his weak spot when he insulted her. Her biggest moment came on Onigashima, where she used her powers to age young Momonosuke into a full adult so he could help save the land.
2. Raizo Turns Enemy Attacks Back on Them

Raizo uses the Scroll-Scroll Fruit to absorb and shoot back massive enemy attacks, including fire and water. During a high-stakes duel against his rival Fukurokuju, both men were locked in place by a paralysis spell while the castle burned around them. Showing ultimate endurance and loyalty to his old master Oden, Raizo stood perfectly still in the flames and outlasted his rival.
1. Fukurokuju Commands With Cold Logic and Ear-Whip Ninjutsu
Fukurokuju was the captain of the Oniwabanshu. He believes ninjas should never show emotion and must only serve the current ruler. He uses his long earlobes like whips to smash enemies or spin them to fly. While he smartly joined Kaido to save his men from death, he secretly worked to protect a surviving Orochi. In the end, his cold logic failed him; he panicked when his clothes caught fire and lost his final battle of endurance against Raizo.
