Naruto: 5 Strongest Kekkei Genkai That No Longer Exist in Boruto, Ranked

The Naruto series introduced several powerful Kekkei Genkai, but not all of them made an appearance in the sequel series. Some belonged to clans that were wiped out, while others were tied to characters and anime-original storylines that Boruto has barely revisited. With the sequel focused on new threats and abilities, these forgotten powers have little room to return.

Still, that doesn’t make them any less dangerous. With that said, these five strongest Kekkei Genkai had abilities that could give even the strongest shinobi a serious fight.

5 The Iburi Clan Could Turn Their Bodies Into Smoke

Imagine facing a shinobi who can let your attacks pass straight through their body. That was the nightmare of fighting the Iburi clan, whose members could turn themselves into smoke and slip past many ordinary attacks. Their abilities appeared during the Kakashi Anbu arc in Naruto Shippuden, giving this forgotten bloodline a clever edge that many opponents would struggle to handle.

Offensively, they could enter an opponent’s airways to suffocate them from the inside. However, the real problem was that this power came with a dangerous weakness. Strong winds could scatter their smoke and put their lives at risk. That extreme vulnerability keeps them at the bottom of this ranking, but their unique mechanics still make them one of the deadliest infiltration bloodlines the franchise ever created.

4 Shikotsumyaku Was Once Naruto‘s Deadliest Bone Weapon

Kimimaro proved that bones can be far more frightening than any sword. His Shikotsumyaku let him pull bones from his body, turn them into weapons, and harden his skeleton to withstand attacks. During the Sasuke Retrieval arc, his final Dance of the Seedling Fern turned the battlefield into a forest of deadly bone spikes.

What makes Shikotsumyaku so impressive is that it offers both attack and defence without needing a separate weapon. Kimimaro was already a dangerous fighter before using his biggest techniques, and his illness was the main thing holding him back. Unlike the Iburi clan’s fragile smoke form, it carried no obvious elemental weaknesses, earning it a higher spot.

3 Typhoon Release Could Even Push Back Sasuke’s Susanoo

Most shinobi would be thrilled to land a clean hit on Sasuke. Nowaki’s Typhoon Release went a step further by creating a storm so enormous that it briefly forced Sasuke’s Susanoo onto the defensive. His powerful wind techniques, shown in the Naruto Shippuden: Sasuke Shinden adaptation, made him stand out despite receiving very little attention in the wider franchise.

The scale of this ability is what makes it so exciting. Nowaki could create storms that covered an entire island, turning the surrounding area into a weapon and making it harder for enemies to see or move freely. Shikotsumyaku is deadly at close range, but Typhoon Release can threaten opponents across a huge area. That destructive reach gives it the third position.

2 The Kurama Clan Used Genjutsu That Hurt in Real Life

Genjutsu is dangerous enough when it traps someone in an illusion. The Kurama clan’s rare ability takes that idea to a much darker level: its strongest users could create illusions so powerful that the victim’s brain made the imagined injuries real. The anime’s Yakumo Kurama arc in Naruto explored how frightening this power could become.

The best part is how it changes the rules of a fight. A stronger opponent means little if they cannot tell what is real, and a single convincing illusion can turn a battle around. However, Yakumo struggled to control her power, making it dangerous even for her. It ranks above Typhoon Release because it attacks the mind rather than simply overwhelming an opponent with force.

1 The Ketsuryugan Turned Blood Into Explosives

The Sharingan and Byakugan often steal the spotlight, but the Ketsuryugan deserves more attention. This rare dojutsu in Naruto belongs to the Chinoike clan and combines powerful genjutsu with the ability to control iron-rich liquids. Chino demonstrated its potential in the Sasuke Shinden storyline, where the eye’s unusual abilities made her a dangerous opponent.

What puts the Ketsuryugan at the top is its mix of tricks and raw danger. Its user can manipulate iron-rich liquids, trap enemies in illusions, and use the Exploding Human Technique to turn a bleeding target into an explosive weapon. While the Kurama clan’s Genjutsu is purely mental, the Ketsuryugan dominates both the mind and physical matter. With zero active users roaming the shinobi world in Boruto, it remains the absolute deadliest bloodline left behind.

Now the big question: Which of these forgotten Kekkei Genkai deserves to return in Boruto the most? Share your thoughts in the comments section below.
