Character development is key. In good fanfiction, we might see Aang grow in his understanding of Appa's needs and vice versa. Also, an engaging plot that takes them on new adventures, like exploring uncharted regions or facing new enemies, makes for great fanfiction. It should also be true to the original spirit of the characters from the source material.
Sure. One popular aang and appa fanfiction is 'The Adventures of Aang and Appa: Beyond the Nations'. It tells about their journey to unexplored lands. Another one is 'Appa's Secret Bond with Aang' which focuses on their deep emotional connection.
Well, without more context about the book story, it's hard to say for sure. If the book is about a complex web of relationships, they could be related in various ways. For example, Appa could be a mentor to Andre and Aakasha, or perhaps Andre and Aakasha are on a quest together and Appa is someone they meet along the way. But again, this is all speculation without knowing the details of the story.
Yes, if the title 'aang is a firebender fanfic' is to be taken literally, then aang is likely a firebender within this fanfic. However, without actually reading the fanfic, there could be some sort of plot twist or alternative interpretation that might make it not so straightforward.
He could meet his future self. It would be an interesting encounter as he could learn from his future experiences and wisdom. Or he might meet people who have studied his past adventures and see himself through their eyes.
He might start by observing. Aang is a curious person, so he'd likely watch how people live, how they interact with technology. He may also try to find other benders to learn about any new developments in bending. And he'd probably use his kind heart to make friends easily in this new future environment.
In some fanfictions, Aang's connection to his past lives plays a crucial role. He could draw on the wisdom and skills of previous Avatars. They might guide him on how to defeat Azula specifically. He could learn a new bending technique from one of his past lives that gives him an edge over Azula's firebending, like a unique way of using water to extinguish her most powerful fire blasts.
Well, Aang being the Avatar has a deep connection with the elements. In this fanfiction, perhaps he enters the Avatar State and uses all his elemental powers in harmony. He could use waterbending to create moisture and cool the volcano, combined with his airbending to disperse the heat and gases.
Sokka would also be a common character. His strategic mind could be very useful in a different time period. He might be the one who figures out how to deal with the new situations they encounter while in the past. For instance, if they need to outwit an enemy in a historical battle, Sokka would be the one to come up with a plan.
In some fanfiction, Aang's tattoos might be depicted as glowing with a special power when he reaches a new level of understanding or connection to the Avatar state.
