Maybe it would be an ice - dragon. This would be an interesting contrast to Naruto's usual warm - natured self. The ice - dragon could have blue - white scales and the ability to freeze things with its breath. It could also create ice - bridges or walls in battles, providing a unique strategic advantage for Naruto.
Well, it could change a lot. For one, Naruto would have a super powerful ally. The dragon could help him in battles against tough enemies like Pain or Madara. It might also change how others in the village see him. Instead of just being the Jinchuriki of the Nine - Tails, he'd be the guy with a dragon too. This could lead to new adventures as he tries to figure out how to take care of the dragon and use its powers to protect the village.
There probably is. Fanfiction is a vast realm of creativity. In a story where Harry has a pet dragon, it could be a dragon egg that he stumbles upon during one of his escapades. He might raise it secretly at Hogwarts, with the help of his friends like Ron and Hermione. This dragon could become a symbol of his growing power and independence outside of the traditional magic he has been taught, and would surely lead to some exciting and unexpected plot twists in the fanfiction.
Perhaps the dragon has some connection to Harry's family. It could be a gift from an ancestor who had a special bond with dragons. In the wizarding world, there are often secrets in family histories that could lead to such a situation. Harry might find out about this connection as he delves deeper into his family's past, and that's how the dragon comes into his life.
Maybe there are other dragon hunters in the story. These hunters see Natsu's pet dragon as a valuable trophy. They don't care about the bond between Natsu and the dragon. They just want to prove their skills by taking down such a powerful creature. So they keep chasing Natsu and his dragon throughout the fanfiction.
Well, perhaps the fanfiction could be about Natsu training his pet dragon. He has to teach it how to fly better, control its strength, and also how to be stealthy. Along the way, they make friends with other magical creatures who also help in the dragon's training. And then they face a big challenge where the dragon's new skills are put to the test.
Well, Naruto might have some training sessions with his pet tiger. The tiger could be a great sparring partner, teaching Naruto new combat skills or helping him improve his reflexes. They could also go on missions together, with the tiger using its natural abilities like stealth and speed to assist Naruto in completing the tasks.
The pet dinosaur could be from a hidden part of the Naruto world, perhaps a place where ancient and extinct creatures were preserved by some kind of powerful jutsu. Maybe it was discovered during one of Naruto's adventures, like in a deep, unexplored forest or a secret underground cave.
