A cool idea could be a Naruto character who discovers they have a dinosaur bloodline and starts to grow small dinosaur features, like claws. This affects their fighting style as they learn to use these new features in combat. Another idea is a clan that has been secretly hiding their dinosaur bloodline for generations due to fear of being persecuted. They have unique jutsus based on different dinosaur traits.
The dinosaur bloodline in Naruto fanfiction could be a result of a curse or a blessing from a powerful entity. For instance, a god - like being was impressed by the dinosaurs' strength and decided to preserve their essence. A chosen ninja is then bestowed with this dinosaur bloodline. This would give the ninja abilities such as breathing fire like some believe certain dinosaurs could do, or having a powerful tail attack similar to a stegosaurus.
It could completely change the dynamics of his powers and his journey. Maybe he'd have an easier time mastering jutsu or face new challenges related to his unique bloodline.
He could turn into a T - Rex. It's one of the most iconic dinosaurs, known for its powerful jaws and great strength. Naruto as a T - Rex would be a fearsome sight with his massive size and ability to crush opponents.
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.
In some fanfics, Naruto absorbs the bloodline through a special jutsu. For example, he might find an ancient scroll that contains a jutsu allowing him to transfer and absorb the genetic traits related to a bloodline.
Some of his friends might be in awe of him. They could see him as even more of a hero or someone to look up to. For example, Konohamaru would probably be even more excited to train with Naruto and learn from him. However, some friends might also be a bit jealous of his new powers. Sakura might initially be a bit wary, but she would also be concerned about how Naruto is handling this new power.
In these fanfictions, a common unique feature of the Hozuki bloodline is the ability to turn into a liquid - like form. This allows the characters with this bloodline to pass through small spaces, avoid attacks, and even trap enemies within their liquid bodies.
In 'The Last Naruto Novel', if there is an 'organic dinosaur' mentioned, it could be some sort of ancient creature that has a role in the story's lore. Maybe it's a creature from a forgotten era that has some significance in relation to the ninja world, like perhaps it was a guardian of a powerful jutsu or a relic. However, this is all speculation without further details from the novel.
One unique ability could be the power to manipulate bones at a molecular level. This would allow the character to reshape their bones into various forms, like sharp weapons or protective shields. Another ability might be the capacity to sense vibrations through the bones, giving them an edge in combat by detecting enemy movements even through solid objects.
