One idea could be that in the future time in an Avatar fanfic, the Na'vi have developed advanced technology while still maintaining their connection to Eywa. They could use new forms of flying mounts that are a blend of their natural creatures and some sort of bio - mechanical enhancements. For example, a banshee with wings that can adjust shape for better speed and stealth, powered by the Na'vi's own bio - energy.
A fanfic set in a far - future time for Avatar could show a Pandora that has become a hub for intergalactic trade. The Na'vi, having learned from the humans, now have their own space - faring vessels. They travel to other planets to share their knowledge of Eywa and learn about different cultures. This would completely change the dynamic of the Avatar universe as we know it, with the Na'vi no longer being just a tribal species on Pandora.
Well, when it comes to avatar shadow bending in fanfic, it could be a unique form of bending that is either a lost art or something that the avatar discovers through a special encounter. Maybe the avatar is in a dark place, literally and metaphorically, and figures out how to bend the shadows to their advantage. It could also be something that is related to the avatar's state of mind, like when they are in a more shadowy or conflicted mental state, they can access this form of bending. This would make for a very complex and interesting character arc in a fanfic.
A fanfic about Avatar Zhu Li could be really interesting. It might explore her backstory further. Maybe it could show her early days in the Fire Nation, her training, and how she developed her skills. It could also delve into her relationships, like with other important characters in the Avatar universe.
In many fanfictions where Zuko is adopted by dragons, it often changes his entire character arc. He might gain new powers related to the dragons, like enhanced firebending abilities. For example, he could learn to breathe blue fire, which is a more powerful form of firebending. This adoption could also lead to a change in his relationships. He may become more isolated from the human world as he grows closer to the dragons. His view of the Fire Nation's aggression might also shift as he sees the world from a different, more dragon - like perspective.
One possible fanfic could involve a character from Adventure Time learning belly dance. Maybe Princess Bubblegum decides to incorporate belly dance into the Candy Kingdom's cultural events. She could learn the moves from a traveling dancer and then teach her friends. This would add a new and exotic element to the Adventure Time world.
One great 'Avatar: The Last Airbender' time travel fanfic is 'Time's Ripple'. It takes Aang back in time to the era before the Air Nomad genocide. He has to figure out how to stop the events that will lead to the destruction of his people without changing too much of the future. It's a really interesting read as it explores Aang's character in a whole new light and his struggle with the moral implications of time travel.
Their different cultures can be shown through their traditions. For example, Aang being an Air Nomad has different ways of greeting and showing respect compared to Katara's Water Tribe. In a fanfic, a scene could be written where they visit each other's tribes. Aang shows Katara the air temples and explains the significance of the different areas like the meditation chambers. Katara in turn shows Aang the Water Tribe's communal living spaces and how they share resources.
One common gay sex story is about two men who met at a pride parade. They felt an instant connection. After getting to know each other better over coffee, they realized their physical attraction was mutual. Their first sexual encounter was filled with a sense of discovery and excitement as they explored each other's bodies in a safe and consensual way.
A time travel fanfic in the Arpeggio of Blue Steel universe could be really exciting. It could explore different eras of the world in that story, like maybe going back to the time when the Fog first emerged. This would give a chance to see how the initial interactions between humans and the Fog were, and might even change the course of events in the original story.
One common theme is redemption. Zuko often goes back in time to right the wrongs he did in his original timeline, seeking to be a better person. Another theme is the power of knowledge. Since he has knowledge from the future, he uses it to change events, like preventing certain battles or saving lives. For example, in many fics, he might use his knowledge of Sozin's Comet to stop the Fire Nation's initial attack.
