Perhaps a fanfiction where Naruto visits Deadpool's world. Naruto would be completely bewildered by the modern technology and the strange, immoral characters in Deadpool's universe. He'd try to use his ninja way to bring some order and his positive attitude to the rather dark and chaotic world that Deadpool inhabits.
Maybe Deadpool teams up with Naruto. Deadpool's crazy antics and Naruto's determination would make for a really fun and unpredictable partnership. They could go on missions together and Deadpool would constantly be cracking jokes and doing things his own way.
Another plot could involve Deadpool being hired by an unknown force in the Naruto world to assassinate a powerful shinobi. But when he meets Naruto, he has a change of heart. They then work together to uncover the mystery behind who hired him and what their real motives are. Deadpool's fourth - wall - breaking antics could add a comical yet confusing element to the Naruto characters.
One idea could be that Naruto and Deadpool end up in a strange multiverse situation where they meet various female characters from their respective universes. They then have to team up to protect these females from a common enemy, and in the process, a harem - like dynamic forms as the female characters develop feelings for them.
Another interesting concept is a Deadpool game fanfiction set in a post - apocalyptic game world. Deadpool has to team up with other unlikely characters from different games to survive and find a way to restore the world. He would bring his unique brand of comedy and mayhem to the situation. For example, he might constantly make jokes about the scarcity of ammo or the strange mutations of the enemies.
One idea could be that Deadpool somehow gets transported to the Naruto universe. He'd be really confused at first but then start causing all kinds of chaos with his unorthodox fighting style and fourth - wall - breaking humor. Maybe he'd try to team up with Naruto, thinking he could use some of Naruto's cool jutsu in his own battles back home.
One idea could be that Deadpool and Wolverine are forced to team up on a mission in a post - apocalyptic world. They have to battle against a new breed of mutants who have gone rogue. Deadpool's crazy antics would constantly annoy Wolverine, but they'd gradually learn to work together.
Maybe in the fanfiction, Batman is on a mission in another city and runs into Deadpool. Deadpool mistakes Batman for some kind of anti - hero like himself. He tries to befriend Batman and convinces him to break some of his no - killing rules just for one mission against a really bad guy. This could lead to a lot of moral and ethical debates between the two characters as they work together.
Maybe Deadpool could team up with Harley Quinn. Their personalities are both wild and unpredictable. They could go on a rampage through Gotham, with Deadpool constantly breaking the fourth wall and Harley just being her crazy self, driving the Batfamily nuts as they try to figure out how to deal with this odd couple.
One idea could be Deadpool trying to join the Avengers in his own zany way. He might show up at the Avengers' headquarters with a bunch of crazy gadgets and a self - made resume full of his 'accomplishments' that are half - heroic and half - insane.
One idea could be that Deadpool gets accidentally teleported into Stark Tower. He then proceeds to annoy Tony Stark with his non - stop chatter and crazy antics. Stark, at first, is irritated but then realizes Deadpool's skills could be useful in a new project he's working on.
