Sasuke Uchiha is quite a powerful individual, whom many fans know to be one of the most important characters in the entire Naruto franchise. It wouldn’t be a stretch to say that Sasuke is almost as important as Naruto Uzumaki himself. The author himself has confirmed this on many occasions, and, consequently, Sasuke has remained quite relevant, even after the conclusion of the Fourth Great Ninja War.
In the original series, Sasuke reached a very high level of strength, becoming one of the strongest in the entire world by the end. However, Sasuke still managed to achieve great things after the war ended. On his journey across the world, Sasuke bettered himself in many ways and did things that only a handful of fans know of.

Mastered The Rinnegan
Sasuke Uchiha awakened the power of the Rinnegan in the 4th Great Ninja War. Even though he was great at using it, he was not a master of this ability at the time. In fact, by the time he first fought against Kaguya, Sasuke still had very weak control over his eye. It was only when he was starting to fight against Naruto that he mentioned having better control over his eye.
Still, Sasuke was only able to truly master this eye after the conclusion of the War. By this point, he knew how to utilize this eye properly, and even how to deactivate it. Furthermore, Sasuke also learned other aspects of the power of this eye, such as the ability to rip open portals in space and time and access any dimension, including those of Kaguya Otsutsuki.

Developed New Jutsu
After the conclusion of the Fourth Great Ninja War, Sasuke gained tremendous strength, and given that he is a genius of the Uchiha, it is no surprise to know that he mastered many incredible abilities.
Sasuke became a master of all five elements after the conclusion of the war. He developed a lot of new techniques, such as the Lorentz Gun, and mastered the other elements as well. Clearly, Sasuke was unstoppable by the time of adulthood, and his showings in the blank period and the new era are proof of that.

Helped Defeat Kinshiki and Momoshiki
One of the biggest accomplishments of Sasuke following the conclusion of the war is to save the planet from the likes of Kinshiki and Momoshiki. In the Boruto era, these two powerful individuals turned their eyes towards planet Earth, in search of a powerful source of chakra, which they detected inside Naruto’s body.
As such, not only did they threaten the earth, but the entire world itself. Thankfully, Sasuke and Naruto were able to deal with this threat. On Momoshiki’s very own planet, Sasuke was the one who actually ended up saving Naruto, and then, the two combined their forces to defeat the two Otsutsuki at once. Their strength was so incredible that the powerful Otsutsuki that even Kaguya feared stood absolutely no chance.

Saved Naruto’s Life
One of the many incredible things that Sasuke managed to do after the 4th Great Ninja War was to save Naruto’s life. At some point during his reign as Hokage of the village, Naruto contracted a very dangerous illness. Sasuke decided to set out on a journey to Redaku City, where he found a cure to this illness.
This was the same illness that the Sage of Six Paths once had. As a result, Sasuke found whatever clue that he could in an attempt to fight this illness. With Sakura’s help, the two were finally able to get the cure, and, with that, Sasuke was finally able to save his friend’s life once again.

Saved Boruto Uzumaki’s Life
While Sasuke certainly did save Naruto Uzumaki on more than one occasion, he also did the same for his son, Boruto Uzumaki. Sasuke trained Boruto many years after the conclusion of the Fourth Great Ninja War. Even when Omnipotence struck and the vast majority of the people did not truly know who Boruto was, Sasuke decided to believe his daughter and train this individual.
When Code attacked these two, Sasuke laid down his life and gave Boruto the chance to escape. In an incredible showing of strength, not only was he able to take Code’s eye, but he was able to chop down his Claw Grime army as well.

Became Naruto’s Equal
Sasuke and Naruto have always progressed together. When one receives great power, so does the other. These two grew in terms of strength and maturity side by side, and they experienced many battles together. However, towards the end of the 4th Great Ninja War, it was clear to the fans to see that Naruto had pulled ahead of him.
When the two fought for the last time, Naruto was dominant. Even though he was not trying to kill Sasuke, he was still able to win their battle, despite Sasuke having the aid of the nine Tailed Beasts on his side. Furthermore, Naruto then gained even further strength when he received the second half of Kurama, thus getting a major power boost once again. While Sasuke had been left behind at the end of the series, he managed to catch up to Naruto by adulthood. As mentioned by the author himself, both Sasuke and Naruto are equal in the new era of Boruto, which means that Sasuke trained relentlessly during the blank period and achieved incredible strength.
Naruto and Boruto are available to watch on Crunchyroll.
