Well, it could start with Percy Jackson being somehow transported to the Avengers' world. He'd be really confused at first, seeing all these high - tech gadgets and super - powered humans. Then, they realize they have a common enemy. Maybe Thanos has gotten his hands on some Greek artifacts that give him new powers. Percy, with his skills in combat and his connection to the sea, teams up with Thor, who also has power over lightning and storms. They could fight side by side, with Percy using his sword and Thor his hammer. The other demigods and Avengers would also have to find ways to work together, like Annabeth using her strategic mind to help Captain America plan battles.
The plot could involve Percy Jackson's world of Greek gods colliding with the Avengers' universe. Maybe the gods have some sort of issue that only the Avengers' powers can help with, or vice versa. For example, an ancient Greek monster has been unleashed in the modern world that the Avengers are struggling to defeat, and Percy and his friends come in with their knowledge of Greek mythology to assist. It could also be a situation where the Avengers are dealing with a threat that has its roots in Greek magic, and they need Percy's demigod powers to counter it.
Well, one possible plot could be that the gods in the Percy Jackson universe notice some strange energy disruptions caused by the Infinity Stones in the Avengers' world. Percy and his friends are sent to investigate. They meet the Avengers and at first there are misunderstandings, like the Avengers thinking Percy's powers are from some new form of alien technology. But then they realize they need to work together to stop a common enemy, perhaps a new powerful being that is drawn to the combined power of the demigods and the Infinity Stones.
A Percy Jackson and Avengers crossover fic could be really exciting. Imagine Percy's water powers combined with Thor's lightning. They could create some really powerful elemental attacks. And the Avengers could be baffled by Percy's ability to talk to sea creatures. Maybe they'd team up to fight a common enemy like a new super - powerful Titan or a group of evil Asgardian - Greek hybrids.
Well, it could be that the Voltron team somehow gets transported to the Percy Jackson universe. Maybe they end up at Camp Half - Blood and have to team up with the demigods to fight a common enemy, like a new type of monster that is a combination of a Galra and a Greek mythological beast. The Voltron lions could be seen as some sort of strange new magical creatures by the demigods.
It could be amazing. Maybe Percy uses his water - controlling powers to help the Avengers during a flood - like attack in New York. He could team up with Thor, who also has powers related to a natural element. They'd make a great duo fighting off villains.
A great plot could be that Thanos somehow discovers the power of the Greek gods and tries to steal it for himself. He starts by attacking Camp Half - Blood. The Avengers, who are aware of some strange energy signatures coming from that area, go to investigate. There they meet Percy and his friends. At first, there is mistrust, but they soon realize they need to work together. Percy and his friends help the Avengers understand the magic and powers related to the Greek gods, while the Avengers offer their high - tech weaponry and combat skills. They then embark on a journey to stop Thanos from achieving his goal, facing many challenges along the way, including some Greek monsters and Thanos' minions.
The plot could involve a villain who has found a way to cross between the two worlds. This villain starts causing chaos in both the world of Percy Jackson, like turning demigods against each other, and in Eragon's world, by disrupting the dragon - rider bond. Percy and Eragon, being the main heroes, have to team up. They start by trying to understand each other's powers and the rules of their respective worlds. Along the way, they make new friends and allies from both worlds and face many challenges together until they finally defeat the villain and restore peace in both their worlds.
In such a crossover, there could be epic battles. Percy might use his water - controlling powers against the Avengers' enemies. Maybe Thor and Percy would have an interesting encounter, comparing their powers over elements like water and lightning.
One plot idea could be that Percy Jackson discovers a magical artifact that somehow links his world to the Marvel Universe. Thor senses the power of this artifact and comes to investigate, leading to a meeting with Percy. Meanwhile, the Avengers also get wind of it and think it could be a threat. So, they all end up in a big showdown where they have to figure out if they're on the same side or not.
Imagine if the gods in the Percy Jackson universe decide to test the mortals in the Kickin It world. They send Percy as a sort of envoy. Percy arrives at the dojo and challenges the students there to a series of tests. At first, the Kickin It gang is angry and confused. But as they engage in these tests, they start to learn about their own hidden potential. Meanwhile, a dark force from the underworld notices this interaction and tries to disrupt it. Percy and the Kickin It gang then have to work together to defeat this dark force. Along the way, they exchange their skills and knowledge, with Percy teaching them about Greek mythology and the Kickin It gang teaching him martial arts moves.
The plot could start with Batman getting an invitation from SHIELD. They've noticed some strange activities in Gotham that seem related to a threat that could affect the whole world. Batman joins the Avengers. He quickly realizes that their methods are very different from his. But he uses his stealth and detective skills to gather information that the Avengers couldn't. For example, he discovers a hidden base of the villains by following a small clue.
