He could create an Ice Clone Jutsu, similar to his Shadow Clone Jutsu but made of ice. These clones could be used for various purposes, like distracting enemies or freezing them on contact.
One possible new jutsu could be the Ice Prison Jutsu. Naruto would be able to trap his enemies within a large ice structure. The ice prison could be designed in such a way that it slowly drains the chakra of the trapped enemy while keeping them immobilized. This would give Naruto an upper hand in battles, especially against strong opponents where he needs to weaken them first before delivering a final blow.
Naruto might develop an Ice Dragon Jutsu. He could summon a large ice dragon that can breathe out freezing blasts. This jutsu would be extremely powerful and could be used to take on multiple enemies at once or to attack large structures.
He could potentially create a jutsu that combines the Rasengan with the Byakugan's ability to see chakra points. For example, he could create a Rasengan that specifically targets an enemy's chakra points, making it a more lethal and precise attack. Maybe he could call it the Byakugan - Rasengan. Another possibility is a jutsu that uses the Byakugan's long - range vision to track an enemy's movements and then sends out a series of shadow clones that are guided by that vision to surround and attack the enemy.
He could create a jutsu that allows him to teleport short distances. Given his quick thinking and need for mobility in battles, a short - range teleportation jutsu would be very useful. It could be like a mini - version of Kamui but powered by his own chakra.
Naruto might develop a 'Fire Clone Barrage'. He would create a large number of fire clones using the Mera Mera no Mi and then send them all towards his opponents in a wave. The clones could explode on contact, causing massive damage with their fire - based attacks.
One possible new jutsu could be an 'Armor - Boosted Rasengan'. Naruto could use the power - enhancing features of Genji's armor to supercharge his Rasengan. The armor might be able to add an extra layer of energy or stability to the jutsu, making it larger and more destructive. Another idea is a 'Stealth - Dash Jutsu'. Since Genji's armor is often associated with quick and stealthy movements, Naruto could develop a jutsu that allows him to quickly dash and become invisible for a short time, similar to some of Genji's abilities in his own universe.
He could create a 'Super - Flight Jutsu'. Since he has Superman's ability to fly, he could combine it with his ninja techniques. Maybe he could make a jutsu where he flies at high speed and creates a shockwave around him to knock out enemies. Another one could be 'Heat - Vision Beam Jutsu', where he focuses his heat vision like a chakra - powered beam.
He could create a jutsu where he combines his Rasengan with Kimimaro's bone - spike attack. The Rasengan could be surrounded by sharp bone - spikes, making it a more lethal and hard - to - dodge attack.
He could create a jutsu that combines Ice (a sub - element of Water) and Lightning. This jutsu could freeze opponents while also shocking them with electricity. Another one could be a combination of Sand (sub - element of Earth) and Fire, creating a super - hot sandstorm.
He could create an 'Explosive Rasengan'. By infusing the explosive properties of Deidara's bloodline into his Rasengan, it would be a jutsu that not only has the rotational force of the Rasengan but also the explosive power of Deidara's clay. It would be extremely powerful and could cause massive destruction.
A potential new jutsu could be 'Rinnegan - Hyton Ice Storm'. Naruto would first use the Rinnegan to sense the surrounding area and locate his enemies. Then, he would use his Hyton to create a powerful ice storm. The storm would be filled with shards of ice that are not only sharp but also infused with chakra from the Rinnegan. This would make them extremely difficult to defend against. Another jutsu could be 'Hyton - Rinnegan Ice Shield'. He could use his Hyton to create a large ice shield and then use the Rinnegan to reinforce it, making it capable of withstanding powerful attacks.
He could create a jutsu like 'Blood Clone Jutsu'. Using Alucard's ability to manipulate blood, Naruto could create clones made of blood that have the same strength and abilities as him. These clones would be more durable than his regular shadow clones and could even explode on contact, causing damage with the blood splatter.
