1. Fire and Lightning God Technique: Sasuke combines Amaterasu and his Mangekyou Sharingan's ability to control black flames with his Chidori technique. This technique is effective against Naruto's Shadow Clones.

2. Dragon Earth Cave Sage Technique: Sasuke could surpass Naruto in power if he learns this technique. It would give him an additional mode to fight in, surpassing Naruto's modes.

3. Demonic Statue of the Outer Path: The Demonic Statue, summoned by those with the Rinnegan, can absorb the chakra of the Tailed Beasts.

4. Manipulating Kawaki: Sasuke could try to manipulate Kawaki, who is believed to have killed Naruto in Boruto. The new generation of shinobi seems to possess greater powers, making it difficult for Naruto to win against both of them.

5. Joining forces with the Otsutsuki clan: In Boruto, there is a new villainous organization and members of the Otsutsuki clan. Sasuke joining forces with them would make defeating Naruto easier, as the Otsutsuki clan possesses incredibly strong power.
