Another ability could be time - related magic. Since they are immortal, it makes sense that they have some control over time. They might be able to slow down or speed up time in a small area, or even travel through time to different eras in the Marvel Universe. This could be used for various purposes, such as preventing a disaster from happening in the past or getting knowledge from the future.
The Sharingan gives the ability to see chakra, which in a Marvel context could be translated to seeing energy or life forces. So they could detect hidden enemies or sense the power levels of other characters. Also, the ninja skills would include things like super - fast movement, stealth, and proficiency with various weapons like kunai and shuriken.
In terms of power levels, the Immortal Mage could have powers that are on par with the likes of Scarlet Witch or Doctor Strange. Their immortality might also come with the ability to regenerate from any injury, making them a formidable force. They could also have the power to travel through different dimensions, which is a common theme in Marvel. This would allow them to access hidden knowledge and artifacts that could be used to either protect or disrupt the Marvel Universe depending on their motives.
Well, Naruto has some really unique abilities like his shadow clones and chakra control. In the Marvel universe, his shadow clones could be used in a similar way to how Wolverine uses his healing factor to be in multiple places at once during a battle. His chakra control might be seen as a form of energy manipulation, like Scarlet Witch's powers but more focused on internal energy. It could add a whole new dynamic to the battles and storylines in the Marvel world.
Another possible alliance for Naruto in Marvel fanfiction could be with the Guardians of the Galaxy. His immortality would give him the confidence to explore the cosmos with them. He could use his chakra to help power up their ship or provide combat support during space battles.
Well, some people like to give their OCs magic related to time. They can either slow down time to gain an advantage in combat or speed it up for themselves to move faster. Spatial magic is also interesting. The OC could create portals to quickly move from one place to another or use it to trap enemies in a small pocket of space. There's also magic that manipulates emotions. The OC could make enemies feel fear, confusion, or even love, which can disrupt their fighting abilities. And of course, transformation magic, where the OC can change their form into something else, like a powerful beast or a small creature for stealth purposes.
He could have elemental magic like fire or ice. Fire magic would be really powerful, allowing him to create intense blazes to attack enemies. Ice magic could be used for both defense, creating ice barriers, and offense, freezing opponents. Another option could be summoning magic, where he summons mythical creatures to fight by his side. For example, he might summon a phoenix that can heal him with its flames or a griffin for its strength in battle.
Elemental magic is quite popular. Fire magic for offensive power, ice magic for defense and crowd control. Another popular one is healing magic. It's useful in a team - based story like RWBY. Teleportation magic is also cool. It allows the OC to move quickly around the battlefield or escape danger.
Shikamaru might possess a magical ability similar to Legilimency. His ability to read people in Naruto could translate into being able to read minds in Hogwarts. This would give him an edge in many situations. Sakura could have an extraordinary gift for Healing Magic. Combining her existing medical skills with Hogwarts' magic, she could heal the most severe of wounds and even develop new healing spells.
She could have her classic Harry Potter abilities like magic. So, she could cast spells, use charms, and perform transfigurations. In the context of Highschool DxD, she might be able to combine her magic with the supernatural elements of that world. For example, she could use magic to enhance her physical abilities like speed or strength, similar to how the devils and angels have their own powers.
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.
