Maybe Naruto would have the power of cosmic energy projection. He could shoot out powerful blasts of energy that are a mix of his chakra and cosmic forces. This would be a great offensive weapon against the Avengers' enemies.
One possible cosmic power for Naruto could be the ability to control cosmic storms. He could summon these storms which would consist of a combination of natural elements like wind, lightning, etc., but on a much larger and more powerful scale. This would give the Avengers an edge in large - scale battles.
Percy could have his water - controlling powers from his original story. In the Avengers fanfiction, this could be really useful against fire - based villains or in situations where they need to manipulate water for various reasons, like putting out fires in a big city during an attack or using water to create barriers against enemies.
Well, Naruto's cosmic powers would likely make the Avengers more powerful as a whole. His ability to create multiple clones could be used for various strategic purposes during battles. Also, his chakra powers might offer a new energy source or way to combat enemies that the Avengers haven't encountered before. This could lead to new team formations and battle strategies.
In fanfiction, Naruto as a celestial wizard could possess the power of celestial star magic. This type of magic could allow him to use the power of the stars for various purposes. He could create powerful star - based attacks, like shooting star beams at his enemies. He could also use the stars to navigate through different dimensions or gain knowledge about future events, adding a whole new layer of mystery and power to his character.
The baby could potentially have Naruto's chakra powers. Since Naruto has a vast amount of chakra and can access the Nine - Tails' power, the baby might inherit some of that. Maybe it could also have some unique abilities from the OC. For example, if the OC has a special type of jutsu related to nature manipulation, the baby could have a combined form of that and Naruto's powers.
A vampire in a Naruto fanfic might possess the power of hypnotism. This could be used to manipulate other characters, much like the Sharingan in some ways. They could also have the ability to transform into a bat - like form for quick movement or stealth. Additionally, they could have a regenerative ability that is much faster than normal Naruto characters, which is related to their vampiric nature.
Alucard might have the power of shapeshifting, which could be used to deceive his enemies in the Naruto universe. He could also have the ability to control shadows, a power that would be quite unique in the world of ninja. This would allow him to move stealthily and ambush his foes. Additionally, his immortality would be a huge advantage, as he could keep coming back in battles no matter how severe the damage.
In this fanfiction, a godlike Naruto might possess the power to control all types of elements. Not just the five basic elements in the Naruto universe but also the magical elements present in Familiar of Zero. He could use this to create powerful attacks or defenses. He may also have enhanced senses, allowing him to detect hidden enemies or magic traps easily. Another power could be the ability to heal himself and others quickly, which would be very useful in the often - dangerous Familiar of Zero world.
Devil Naruto might possess the power of flight, which is common among devils in Highschool DxD. His chakra could be infused with devil energy, making his jutsus more powerful and having additional effects like draining the opponent's energy. His shadow clones could also be enhanced to have some devil - like characteristics, such as being able to resist certain types of attacks better.
He could have enhanced vision powers, like seeing through illusions more easily or being able to detect chakra signatures from a much greater distance. The red eye might act as a sort of sensor, similar to how the Byakugan can detect things, but with its own unique properties.
He could have the ability to manipulate the concept of law itself. For instance, he could make it a 'law' that any attack aimed at him misses. This would be like a natural defense mechanism. Another ability could be to set laws on the use of chakra, like 'only I can use fire - style jutsu in this area' which would disrupt his opponents' combat strategies.
