Naruto and Sasuke are two of the most famous characters Boruto series. It wouldn't hurt to say that these are the most popular characters who are the face of the entire franchise. Quite a lot Boruto fans started watching the series because of Naruto and Sasuke, and it wouldn't be a surprise to know that they are completely disappointed with the treatment of these two characters.

Himawari becomes one of Boruto's strongest characters. He will surpass these legendary ninjas.
While the Naruto series made them legends of the world, the Boruto series stripped them of all abilities. Right now both Naruto and Sasuke are incapacitated, but they will eventually come back. When Naruto and Sasuke return, fans know they must be stronger than beforewhich would require them to obtain new forces.
New Sword (Sasuke Uchiha)
One power-up that has already been confirmed for Sasuke Uchiha after his return to Boruto is a new sword. Fans know that after Sasuke was turned into a tree, his sword was taken over by Boruto Uzumaki. lately this sword was upgraded by Sumire using technologies from the future.
This sword is now more dangerous and powerful than ever before. It also has the unique ability to always be coated with the user's chakra, making it even more powerful. In addition, the sword has a special ability that has not yet been revealed and will most likely be revealed during the climax of the ongoing arc. Sasuke's chakra had already been registered by the sword and he would most certainly be able to access it again when he returned.
New Prosthetic Hand (Naruto Uzumaki)
When it comes to Naruto's upgrades, fans know that one of the most interesting ones that he could have access to in Boruto upon his return is a new prosthetic hand. Naruto already tried one prosthetic hand in Boruto and it allowed him to absorb all forms of ninjutsu. Back then, this hand was only a prototype as it couldn't expel chakra like Momoshiki's Rinnegan.
However, it could be upgraded again. After the latest upgrades, it can be said that this prosthetic hand will most likely be a phenomenal power-up for Naruto Uzumaki, allowing him to fight at the highest level again.
Total Strength Increase (Naruto Uzumaki)
Naruto Uzumaki would also need an overall power boost in the Boruto series after he returns. This is because Sasuke Uchiha already gained a power boost during the timeskip. It's already been confirmed that Sasuke trained tirelessly during the timeskip before he was sealed away. This is exactly why he was able to compete against Code and his Claw Grimes and even take one of Code's eyes.
Naruto remained sealed during this time, which is exactly why he would need to catch up with him upon his return. The series will most likely adjust Naruto's power levelwhich means he won't have to go through training for it.
Wood Release (Naruto Uzumaki)
Naruto Uzumaki has many exciting potential improvements lined up in the Boruto series, provided the author doesn't wrong him again. One of the most exciting upgrades Naruto Uzumaki can get in Boruto upon his return is Wood Release.
This is already known Naruto possesses Hashirama Senju's DNA through his prosthetic arm that he received at the end of the Fourth Great Ninja War.

Sasuke has been nerfed but still has many powerful abilities in Boruto.
This is also known Naruto can manipulate all five Nature Changes as an adult. As such, it's pretty easy to see how Naruto should be able to use it Releasing wood at will. Now that he has lost Kurama's power, Naruto should be able to use this ability to give himself an advantage in battle.
Tailed Beast Chakra (Naruto Uzumaki)
While Naruto Uzumaki lost the power of Kurama v Borutothat doesn't mean they have to lose the power of other tailed beasts also. Naruto could still seek out the other Tailed Beasts and reconnect with them, giving him access to their chakra.
This is quite easy to achieve and if he succeeds he could become very powerful again. In fact, even Kurama's loss could be mitigated this way if Kishimoto doesn't back down.
Rinnegan (Sasuke Uchiha)
The fans know this very well Sasuke Uchiha lost access to the Rinnegan after the battle against Isshiki. However, he still possesses one Eternal Mangekyo Sharingan.
It's possible that at some point later, this other eye of Sasuke's will turn into the Rinnegan through a natural evolutionary process. It's a strong possibility, and if it happens, Sasuke will become even stronger.
Lightning Release Chakra Mode (Sasuke Uchiha)
Sasuke uses many interesting abilities in battle and one of the most underrated he could be using Lightning Release Chakra Mode. This ability is incredibly powerful and would give Sasuke almost impenetrable armor as well as amplify his nerve signals to the absolute maximum.
Sasuke would be faster and stronger than ever, hardly anyone could keep up with him in a fight. Kumogakure's Lightning A made incredible use of this ability, and Sasuke could be next.
