Deadpool is crazy and unpredictable, often doing things for his own amusement. Naruto is more about friendship and protecting his village. So Deadpool might do things that Naruto thinks are irresponsible, like attacking enemies without a plan just for fun.
One possible plot could be Deadpool getting teleported to the Naruto universe. He'd be really confused at first, but then he'd start causing chaos. Maybe he'd try to team up with Naruto, thinking he could make some money off their adventures. Naruto, on the other hand, would be both amused and annoyed by Deadpool's antics.
One possible plot could be that Deadpool somehow gets teleported to the Naruto universe. He'd be really confused at first, seeing all the ninjas and strange creatures. He might try to team up with Naruto, thinking he's just another oddball like himself. And together they could face off against some new villain that's a threat to both their worlds, like a powerful demon that's using Deadpool's chaotic energy to break through dimensions.
In a more extreme scenario, Deadpool could end up in Arkham Asylum and think it's a new kind of S.H.I.E.L.D. facility. He'd start interacting with the inmates there, and Batman would have to step in to deal with the chaos Deadpool is causing. Deadpool would see Batman as this dark and brooding figure and keep trying to get him to lighten up.
Definitely Naruto and Deadpool. Naruto's pure - hearted and determined nature would contrast so much with Deadpool's crazy and unpredictable self. It would be hilarious to see Naruto try to understand Deadpool's constant fourth - wall breaking jokes. Another interesting interaction could be between Sasuke and Deadpool. Sasuke's brooding and serious attitude would be a great foil to Deadpool's zaniness.
Well, one possibility could be Deadpool driving the Avengers crazy with his non - stop chatter and crazy antics. He might constantly break the fourth wall in the middle of a mission, making the Avengers wonder what on earth he's talking about. For example, he could start making jokes about how Captain America's suit is so old - fashioned compared to his own while they're in the middle of a fight against a powerful villain.
One great 'deadpool crossover fanfiction' is the one where he crosses over with Spider - Man. It's really interesting to see how Deadpool's chaotic nature interacts with Spider - Man's sense of responsibility.
First, understand the characters well. For Deadpool, his sense of humor, his fourth - wall - breaking nature are key. Then, think of a unique crossover. Maybe Deadpool in a world full of fairytale characters. Also, keep the plot moving and full of surprises.
It's hard to say. Naruto has his powerful jutsu like the Rasengan and his Nine - Tails chakra. But Deadpool is almost unkillable. If Naruto couldn't figure out a way to completely destroy Deadpool, Deadpool would keep coming back for more and eventually wear Naruto down with his unpredictable attacks.
