One of the most memorable characters could be the young dragon trainer. He has a special bond with his dragon and is constantly defying the odds. His courage in the face of danger makes him stand out.
The exiled prince who returns with a dragon at his side is also quite memorable. He has a tragic backstory, having been wrongly accused and exiled from his homeland. But with his dragon, he comes back to reclaim his throne and bring justice. His journey from being an outcast to a powerful leader is full of twists and turns that readers can't forget.
The dragon riders, if there are any, are often very memorable. Their bond with their dragons and the power they wield make them stand out.
Well, there could be the dragon lords. One might be a powerful fire dragon lord who is fierce and protective of his kind. And on the ice side, a wise ice dragon lord who is known for her strategic thinking.
Jon Snow is also quite popular. Imagine if he could ride a dragon? Fanfiction often delves into this idea. His mysterious parentage and his role as a leader make him an interesting character to incorporate into dragon - related storylines. He could be the one to bridge the gap between the ice (the White Walkers) and the fire (the dragons).
Well, Arya Stark is extremely popular in 'ice and fire total war fanfic'. She has this fierce determination and her skills as an assassin make her a force to be reckoned with. Jaime Lannister also has a significant following. His complex character arc, from being seen as a villain to a more morally ambiguous figure, is very interesting. And of course, Ned Stark, even though his story is tragic, his sense of honor and leadership make him a beloved character in the fanfic world. People often rewrite his story in different ways in the fanfic, hoping for a different outcome for him.
Naruto himself could be a main character. He has a natural inclination towards befriending powerful beings, and his determination would make him a great fit to interact with the fire and ice dragons. Sasuke could also be a main character, with his Sharingan potentially having some unique interactions with the dragons' powers.
Raistlin Majere is quite memorable. His complex personality, his thirst for power, and his unique magical abilities make him stand out. He is often in a moral grey area, which adds to his allure.
I think Jon Snow is one of the most interesting. He's a bastard, yet he has a strong sense of honor. His journey from the Wall to becoming a leader is full of twists and turns. Also, Cersei Lannister is interesting in a different way. She's a complex character, full of ambition and pride, and her actions have a huge impact on the story. Another interesting character is Bran Stark. His discovery of his powers and his role in the bigger picture of the story make him stand out.
Since I haven't read it, I can't say for sure. But it could be a young adventurer, a powerful wizard, or even the dragon itself.
In 'Catching Fire', there are quite a few memorable characters. Katniss is the central figure, a strong - willed and brave girl. Peeta, with his gentle nature and unwavering love for Katniss, is also a standout. Then there's Haymitch Abernathy. His drunken yet shrewd guidance to Katniss and Peeta is quite interesting. And Gale Hawthorne, Katniss's friend from home, with his own ideas about the Capitol and the districts, is also a character that stays with you.
Another possible plotline is the discovery of a new breed of dragon that has the combined powers of fire and ice. This causes a stir among the existing dragon communities as they try to figure out what this new dragon means for their future. There could be a race among different groups to either control or protect this new dragon, leading to a series of adventures and challenges.
