A cool concept for commando crossover fanfiction might involve a commando from a military - based story being thrown into a post - apocalyptic world full of zombies. He could use his military training to form a group of survivors and lead them against the undead hordes. Or perhaps a crossover with a superhero universe, where the commando has to work with superheroes to take down a super - villain who has a military - style operation.
You could do a crossover where a commando character is merged with a character from a historical drama. Picture a commando going back in time to a medieval battle and using his modern tactics and weapons (in a secretive way so as not to disrupt history too much) to help a side in the war. This could create a really interesting dynamic between the modern - thinking commando and the more traditional medieval soldiers.
One idea could be to cross a commando character with a character from a fantasy world. For example, a modern - day commando gets transported to a Middle - Earth - like realm and has to use his combat skills to survive among orcs and wizards. Another could be a crossover with a science - fiction universe, like a commando teaming up with a Star Trek crew to fight a new alien threat.
One interesting idea could be a crossover with "Moana". Elsa's ice powers and Moana's connection to the ocean could create a really cool dynamic. Maybe Elsa accidentally freezes part of Moana's ocean and they have to work together to fix it. Another could be with "Tangled". Rapunzel's long hair and her adventurous spirit combined with Elsa and Anna's journey in Frozen 2 would be exciting. Rapunzel could use her hair to help them climb mountains or cross chasms. A third idea is a crossover with "Beauty and the Beast". Belle's love for books and knowledge could help Elsa understand more about her powers and the history of magic in the Frozen world.
One idea could be an Atreus crossover with the world of Harry Potter. Atreus could be a new student at Hogwarts, bringing his own unique skills and knowledge from his Norse mythology background. He might struggle to adapt to the magic of the wizarding world while also showing off his own combat and survival abilities.
Another option is a crossover with a post - apocalyptic world. The garou's survival instincts and combat abilities would be well - suited for this harsh environment. It could either be a lone wolf trying to survive or join a group of survivors, bringing its own set of skills and challenges to the group.
One idea could be a crossover with the Dragon Ball Z and the Naruto universe. Raditz could land in the Hidden Leaf Village and cause chaos, leading to battles with powerful ninjas like Naruto and Sasuke. Another idea is a crossover with the One Piece world. He might end up on the Grand Line and get involved in the Straw Hat Pirates' adventures. Maybe he would try to steal their Devil Fruits or be forced to team up with them against a common enemy.
Perhaps a Gogeta crossover with the DC universe. Imagine Gogeta facing off against Superman. They are both extremely powerful in their own ways. It could explore a battle of strength, speed, and different types of energy. Maybe Gogeta would be intrigued by Kryptonite and how it affects Superman.
One idea could be an Inuyasha and Naruto crossover. Picture Inuyasha in the Hidden Leaf Village, his sword skills and demon powers causing quite a stir among the ninja. Another could be a crossover with Harry Potter. Inuyasha at Hogwarts, trying to figure out magic while also dealing with his own demon - slaying business. Maybe he'd have some interesting interactions with the magical creatures there.
One idea could be a crossover between PVZ and a fantasy world like Middle - earth. The plants could be magical plants with special powers to fight against the zombies which are now some sort of dark creatures from Mordor. For example, the Peashooter could be a small elf - like being that shoots magic peas.
One idea could be a crossover with the 'Percy Jackson' series. Imagine Hogwarts students meeting demigods and having to work together to solve a mystery that involves both magic and Greek mythology. Another could be a crossover with 'Doctor Who', where the Doctor lands at Hogwarts and helps the students deal with a time - traveling threat. A third idea might be a crossover with 'Sherlock Holmes', with Holmes using his deductive skills to solve a magical mystery within the walls of Hogwarts.
One idea could be a crossover with 'Indiana Jones'. The mummy could be part of an ancient mystery that Indy is trying to solve. Maybe the mummy has some sort of power or knowledge that Indy wants.
A crossover with the Avatar: The Last Airbender world would be cool too. Gajeel could be a metalbender from a far - off land. He could interact with Aang and the gang, and his skills could be both a help and a hindrance in their quest to save the world. For example, his metalbending might be useful in building structures but could also cause trouble if misused.
