Uchiha Sasuke is one of the strongest ninjas in the Naruto universe, but in the Boruto series, he has faced significant hardships. After losing his Rinnegan when Momoshiki Otsutsuki stabbed him, many fans believed Sasuke had weakened considerably.
However, this situation won’t last. Creator Masashi Kishimoto has introduced a powerful new ability for Sasuke called the Thorn Soul Bulb, a force that could elevate him to the level of the Ten-Tails.
Kishimoto Unveils Ten-Tails Power for Sasuke

Sasuke Uchiha and Naruto Uzumaki are two of the most beloved characters in the ninja world, and keeping them relevant while honoring their legacy is crucial. Although Boruto: Naruto Next Generations hasn’t always treated them fairly, the current arc, Two Blue Vortex, is correcting those missteps. There’s hope that both Naruto and Sasuke will return stronger than ever.
In fact, Sasuke has already shown his strength in Two Blue Vortex by fighting Code without limits, taking him on alone and even stealing one of his eyes. That alone is a remarkable feat. But Kishimoto wants Sasuke to be even stronger, which is why this new power, Thorn Soul Bulb, has been introduced.
The Thorn Soul Bulb is vital for saving Uchiha Sasuke, much like it was for Moegi. What many fans don’t realize is that the Thorn Soul Bulb contains the essence of Shinju, an extension of the Ten-Tails. This means it holds the DNA of the Ten-Tails, granting anyone who receives it immense power. So when Sasuke obtains the Thorn Soul Bulb from Hidari, he will gain the Ten-Tails’ power and become even stronger.
Sasuke Uchiha’s Next Power-Up

The biggest impact of the Thorn Soul Bulb on Sasuke could be the restoration of his Rinnegan. As fans know, all Shinju possess the Rinnegan, and Sasuke already has the Eternal Mangekyo Sharingan. If he absorbs the Ten-Tails’ essence, his remaining eye could manifest the Rinnegan again, making him an incredibly powerful ninja once more.
Currently, Sasuke is stuck in a difficult spot, but fans can hope for his imminent rescue. Over the next 10 chapters, Hidari is likely to be defeated, which means Sasuke Uchiha will finally return to the main storyline stronger than ever, much to the delight of fans.
