Sasuke Uchiha may not be the main target Boruto continuation of the series, but is still considered one of the strongest ninjas in history. He may have a Rinnegan, but most of his power comes from his Eternal Mangekyo Sharingan. These eyes give Sasuke access to several powerful jutsu and he can use them as much as he can without fear of going blind.
Sasuke's strongest Mangekyo Sharingan jutsu can easily defeat other Kage level ninja. One jutsu in particular has the power to destroy something as large as the Hidden Leaf Village, while another can seriously injure or temporarily kill a tailed beast. Sasuke may have lost his left eye to Momoshiki Otsutsuki, but he should still be able to use all of these jutsu.

Amaterasu produces black flames that can burn anything
Sasuke unlocked Amaterasu when he awakened his Mangelyo Sharingan after Itachi's death and it quickly became one of his offensive jutsu. Just a handful Naruto characters can face Amaterasu, and most have superhuman speed and the ability to absorb chakra. Amaterasu produces black flames in the focus of Sasuke's vision, making it nearly impossible to dodge. It puts a lot of strain on his eye, which is why it keeps bleeding when he uses it in the New Era.
Amaterasu's black flames cannot be extinguished by conventional means and are considered immortal flames as they will burn until the target is completely consumed. Amaterasu usually burns slowly, but Sasuke can instantly burn something with it by focusing on the flames. This was shown when Sasuke turned Shin Uchiha's metal blades to ash in a matter of seconds. Sasuke's Amaterasu can be burned and knocked out by a completely relaxed Eight-Tails, and it would have burned Jigen to a crisp if Jigen hadn't absorbed it with his karma.

Kagutsuchi allows Sasuke to shape Amaterasu's flames
Sasuke created Blaze Release: Kagutsuchi shortly after awakening his Mangekyo Sharingan and first used it against the 4th Raikage during their battle at the Five Kage Summit. He can still use Kagutsuchi in the New Era, but for some reason he didn't use it in his battles against Momoshiki and Isshiki Otsutsuki. With this jutsu, Sasuke can apply shape transformation to Amaterasu's black flames, a feat that even Itachi was unable to do.
Blaze Release: Kagutsuchi can shape Amaterasu's flames in a variety of ways, both for offensive and defensive purposes. He can increase his Susanoo's defenses by enveloping his body in black flames, and he can create a spike-shaped flame barrier around Sasuke. This version not only protects Sasuke, but can stab his opponent. Sasuke can use Kagutsuchi to create a black flame sword that shoots out spike-shaped projectiles every time he swings it, and can use

Susanoo creates a colossal avatar with power similar to a tailed beast
Susanoo has been passed down from generation to generation of the Uchiha clan and is considered the ultimate ability available to those who have awakened the Mangekyo Sharingan in both eyes. Sasuke used it for the first time during the Summit of the Five Kage, but did not achieve full Susanoo until the end of the Fourth Great Ninja War. Susanoo is a jutsu that makes it almost impossible to kill the user as it is considered an absolute defense, but someone as strong as Jigen can break its defenses with a single attack.
When Sasuke uses his Susanoo, he manifests as a colossal samurai avatar with massive wings. This avatar is made entirely of chakra, and its attack power is equivalent to that of a Tailed Beast. Sasuke can split a mountain in half with a single slash of his sword. Sasuke's humanoid Susanoo can shoot a large arrow from a bow that doubles as a shield. Sasuke's Susanoo didn't do much against Jigen, but it can hold its own against members of the Otsutsuki clan like Kaguya and Momoshiki.

Susanoo: Chidori gives Sasuke's Susanoo incredible piercing power
Chidori is Sasuke's signature jutsu and he is only able to use it effectively because his Sharingan takes care of the tunnel vision problem. Throughout the series, Sasuke has developed new applications for the Chidori, including needle-like projectiles and a spear variant. At the end of the Fourth Great Ninja War, when Sasuke fought Naruto in the Final Valley, he used a new variation of the Chidori that could only be used with a full body Susanoo.
Sasuke didn't use Susanoo: Chidori in the New Era, but since he can still use both Chidori and Susanoo, it's still in his arsenal. Susanoo: The Chidori allows Sasuke to create a massive Chidori in the left hand of his Susanoo. This Chidori is as powerful as the nine-tailed beast ball, which has the power to vaporize a small area. This Chidori could have pierced right through Momoshiki's colossal stone golem, but Sasuke probably didn't use it because it was burned seconds before the golem appeared.

Boruto: 8 Strongest Characters Above Naruto Level
Naruto Uzumaki is a living legend, but several of Boruto's strongest characters have moved beyond his powers.

Indra's Arrow is Sasuke's strongest offensive Jutsu
Sasuke became much stronger in the New Era, but Indra's Arrow is still considered his strongest technique. He only used Indra's Arrow once and now that Naruto is no longer a Jinchuriki, it's a jutsu that can make Sasuke the strongest ninja in the world. When Kurama died, so did the ability to see Indra's arrow again, but now that he's reincarnated as Himawari, Sasuke can use it again.
In order for Sasuke to use Indra's Arrow, he needs to absorb chakra from all nine Tailed Beasts and store it in his complete Susanoo body. Susanoo's body changes and Sasuke manifests a long bow and arrow filled with lightning nature chakra. The arrow is strong enough to collide with two Tailed Beast Ball Rasenshuriken infused with natural energy. Indra's arrow can vaporize one of the five great nations and should be strong enough to do the same to the Ten-Tails.
