One idea could be to have the Thundercats arrive in the Avatar world. Maybe they land near a Water Tribe. The Thundercats' advanced technology and unique abilities would be a shock to the Avatar world. Lion - O could form an alliance with Aang. They could learn from each other's leadership styles. The Thundercats could help in the fight against the Fire Nation with their strength and weaponry.
The crossover could start with a strange portal opening between the two worlds. Naruto characters like Sasuke might be intrigued by the bending abilities in the Avatar world. He could try to learn firebending, thinking it could enhance his own fire - based jutsu. And the Avatar characters could be equally fascinated by ninjutsu.
One possible fanfiction could be about Naruto characters finding themselves in the Avatar world. For example, Naruto's determination and never - give - up attitude could be a great addition to the Avatar universe. He might learn bending techniques in a unique way, perhaps by combining his chakra control with the flow of chi in the Avatar world. This could lead to some really interesting battles and character interactions.
Jon Snow would be an interesting character to be an avatar. Given his complex backstory and his role in the fight against the White Walkers, as an avatar he could gain even more powerful abilities. Maybe he could have the power to control the elements, which would be a huge advantage in battles. He could use this to create blizzards against the White Walkers or to put out fires during the sack of King's Landing.
First, you need to understand the characters well. Iroh is known for his wisdom, his love for tea, and his complex past. The Avatar, depending on which one you choose to feature, has their own unique set of powers and personalities. Then, think of an interesting premise. It could be something like Iroh getting lost in the Spirit World and meeting the Avatar there. Next, plan your plot. Decide how the characters will interact and what challenges they will face. For example, they might have to work together to defeat a dark spirit.
It's really hard to say. Naruto in his strongest form, like when he has the power of all the tailed beasts, is extremely powerful. He has incredible strength, speed, and the ability to use a vast array of jutsu. However, Aang in the Avatar state has access to all four elements and can be a formidable opponent. If we consider the Avatar state's spiritual connection, it could give Aang an edge in a battle of wills.
Aang could be a great crossover character. Since he is from the previous Avatar cycle, his different approach to bending and his more laid - back personality compared to Korra could create interesting interactions. He could offer her wisdom from his own experiences as an Avatar.
Trudy Chacon can be a really interesting character in Avatar 2009 crossover fanfiction. She's a human who has a certain level of empathy for the Na'vi, and in crossovers, she could play a role in bringing different groups together. Another popular one is Norm Spellman. His scientific knowledge and his own journey in the Avatar world can be explored further in crossovers.
In Avatar 2009 crossover fanfiction, a cool idea is a crossover with a post - apocalyptic setting. The Na'vi could be faced with the challenges of a world destroyed by humans in a different way. They might have to deal with new threats and also learn from the survivors of the apocalypse. Also, a crossover with a superhero universe could be fascinating. Picture the Na'vi getting superpowers or having to deal with superheroes coming to Pandora.
A possible conflict could be a misunderstanding between the two groups. The Thundercats' brash and direct approach might be misinterpreted by the more diplomatic Avatar world. For example, when Lion - O first meets the Earth Kingdom leaders, his eagerness to solve problems with force could cause tension. This could lead to a series of events where both sides have to learn about each other's cultures to avoid all - out war.
