Naruto himself is often very popular. Since it's related to his world, fans like to see how he would interact with the Omnitrix and its powers. He could use it in his journey to become Hokage, or to protect his friends in new and exciting ways.
In 'naruto omnitrix bloodline fanfiction', a cool concept might be the exploration of different bloodlines through the Omnitrix. Maybe a character discovers a way to unlock hidden bloodline traits within the forms available in the Omnitrix that are related to Naruto's world. This could open up new storylines about heritage and power.
Well, with the Omnitrix bloodline, Naruto might gain the ability to transform into various alien forms. This could enhance his physical strength, speed, and even give him new jutsu - like an alien form might have unique energy blasts. His combat style would become more diverse, and he could surprise his opponents in new ways.
One challenge could be controlling the transformations. If he can't master when and how to transform, it could put him in dangerous situations. For example, transforming at the wrong time during a battle could leave him vulnerable.
One interesting concept could be how the Omnitrix interacts with the unique chakra system in Naruto. Maybe it could transform the user into Naruto characters with added alien abilities from the Omnitrix. For example, turning into Naruto with the powers of Heatblast, allowing for a super - charged Rasengan with fire - based attacks.
Well, he'd probably be super OP. He could transform into all kinds of alien forms and use their powers in his battles. Imagine Naruto using Heatblast's powers to fight against Akatsuki members. It would be a whole new level of combat in the Naruto universe.
In this fanfiction, Naruto might use the Omnitrix to gain various alien forms' powers. He could use those powers to fight stronger enemies in the Naruto universe, like the Akatsuki members. Maybe he would use the powers for stealth or super strength depending on the alien form.
There are also fanfictions where a bloodline is created through some sort of experimental jutsu. For example, a bloodline that allows the user to transform into different elements at will. This would give the character an edge in combat as they could adapt to any situation by changing their form.
Well, for example, Natsu's fire - dragon slayer magic could potentially interact with a heat - based alien form from the Omnitrix. Maybe when he's in that form, his fire magic becomes even more intense or has a different quality to it. He could use his dragon slayer skills to control the heat in a more precise way than the alien form normally allows.
