Harley Quinn could also be really interesting. She has her own brand of insanity, and when paired with Deadpool, it could be a wild combination. They could either drive each other even crazier or form an unlikely alliance based on their shared love for chaos. She might be the only one who can keep up with Deadpool's non - stop chatter and crazy ideas.
Deadpool, without a doubt. His crazy antics, fourth - wall - breaking, and unpredictable nature would add a whole new level of chaos to the already volatile Suicide Squad. He would constantly be making jokes, getting into fights with the other members just for the fun of it, and finding unique ways to solve problems that the more traditional Squad members wouldn't think of.
One interesting pairing could be Edward and Deadshot. Edward's ability to read minds could be really useful in helping Deadshot with his aiming. Deadshot, on the other hand, could teach Edward about human combat techniques that the vampires might not be familiar with.
In a 'Deadpool Suicide Squad crossover fanfiction', it could start with Deadpool getting bored with his usual solo adventures. He hears about the Suicide Squad and decides to crash their party. The Squad initially doesn't trust him, but they soon realize his combat skills are useful. They are sent to infiltrate a high - security facility. Deadpool keeps making jokes and irritating the more serious Squad members. However, as they face various challenges and enemies inside the facility, they start to bond in a strange way. Deadpool might even develop a strange friendship with someone like Killer Croc, who is used to being an outcast like him.
Harley Quinn and Sakura could be a great match. They are both strong female characters with very different personalities. Harley's wild and unpredictable nature could either drive Sakura crazy or inspire her to be more free - spirited. And Sakura could teach Harley some self - defense skills beyond just her acrobatics and baseball bat - swinging.
Definitely Deadpool and Iron Man. Iron Man is all about high - tech and being in control, while Deadpool is completely unpredictable. Their interactions would be full of sarcasm and banter. Deadpool would constantly be trying to get under Iron Man's skin, and Iron Man would be exasperated by Deadpool's antics.
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.
Definitely Deadpool and Iron Man. Iron Man is used to being in control and having high - tech solutions for everything. Deadpool would drive him crazy with his randomness and disregard for rules. It would be fun to see Iron Man trying to keep Deadpool in line while also realizing that he can be an asset in a fight.
Deadpool and Yang could also be really interesting. Yang is tough and has a bit of a hot - headed side. Deadpool would probably egg her on in fights, and she'd either be really annoyed or find his bravado kind of cool. They could have some epic battles together against the Grimm, with Deadpool making inappropriate jokes all the while.
I think Killer Croc and Jinbe would have a really unique interaction. Given that they are both sort of 'fish - like' in their own ways. Jinbe might be initially cautious around Killer Croc because of his more menacing appearance, but then they could bond over their shared strength and their experiences in the water - based environments of their respective worlds.
Another interesting interaction would be between Deadpool and Gray. Gray is cool - headed (pun intended) and has his own unique fighting style with ice - make magic. Deadpool's chaotic fighting style would contrast greatly with Gray's. They could start off as rivals, with Deadpool constantly taunting Gray about his stripping habit, but then as they face a common enemy, they would have to learn to work together. This would lead to some great character development and some hilarious exchanges as Deadpool tries to understand Gray's magic and Gray tries to tolerate Deadpool's antics.
Deadpool and Batman would be really interesting. Batman is all about strategy and discipline, while Deadpool is the complete opposite. Their interactions would be full of tension and humor. Deadpool would constantly try to crack Batman's serious facade with his jokes and antics.
