Well, there are fanfictions that put the Guardians in different universes. For example, a story where they end up in a steampunk - like universe. They have to adapt their technology and skills to this new environment. Also, some fanfictions explore the love story between Drax and a new character, a female alien who helps him deal with his past traumas. And then there are those that simply focus on the team's daily adventures, like trying to find a new place to party in the galaxy.
Another cool fanfiction idea could be a time - travel story. The Avengers accidentally send themselves to the time when the Guardians were just forming. This leads to a chaotic but interesting adventure where they have to work together without ruining the future of both groups.
One interesting fanfiction could be about a team - up mission between the Avengers and the Guardians. Maybe they have to face a new, powerful cosmic threat that neither group could handle alone. For example, a super - villain who can control dark matter and is using it to destroy planets on a whim.
One interesting fanfiction could be about the Guardians and Avengers teaming up to face a new, powerful villain from another dimension. In this story, the different personalities, like Star - Lord's charm and Captain America's leadership, would clash and then blend as they figure out how to defeat the enemy.
A great Guardians of the Galaxy 3 fanfiction concept could be a time - travel story. Maybe the Guardians accidentally get sent back in time and have to interact with their younger selves or even their predecessors in the Guardians' legacy. They would have to be careful not to change the future too much while also trying to find a way back to their own time. Another idea is a fanfiction that delves deeper into the relationship between Nebula and Gamora. How they grow closer or face new challenges together. And a third could be a story where the Guardians discover a new planet full of strange and powerful artifacts that they must protect from various factions who want to use them for evil.
One interesting crossover could be the sharing of power concepts. For example, the chakra in Naruto and the power of the Infinity Stones in Guardians of the Galaxy. The characters from Naruto might be intrigued by the technology and different species in the Guardians' universe. They could team up to fight a common enemy that threatens both their worlds.
A possible crossover in this fanfiction could involve the Guardians getting involved in the Akatsuki's plans. Since the Akatsuki is always after powerful things, they might target the Guardians' technology or the Infinity Stones if they were part of the story. The Guardians, on the other hand, would likely oppose the Akatsuki's more sinister motives, leading to some epic battles. And Naruto and his friends might end up allying with the Guardians to protect their world from the Akatsuki's newfound power sources.
One idea could be a fanfic where the Guardians have to team up with an old enemy to face a new, greater threat. Maybe a powerful cosmic entity that is threatening to destroy entire planets. Another idea is a fanfic focused on the backstory of a particular Guardian, like Rocket, exploring his life before he joined the team in more detail.
A great crossover might involve the magic of Harry Potter being used to enhance the Guardians' weapons or ship. For example, Hermione could use a spell to make the Milano fly faster or make Rocket's guns more powerful. There could also be a plot where the Guardians help the Hogwarts students fight against a new dark force that threatens both the wizarding world and the galaxy.
Well, you could have a plot where the Guardians accidentally stumble upon a parallel universe. In this universe, their counterparts are evil. They have to figure out how to return to their own universe while also preventing their evil doppelgangers from crossing over. Along the way, they might learn some secrets about the true nature of the multiverse and their own roles in it.
One interesting crossover could be the Guardians teaming up with the Rebel Alliance in Star Wars. Maybe they help in a big battle against the Empire. The Guardians' unique skills and the Rebel's cause would make for an exciting story.
