Who would be the most interesting character interactions in a Fairy Tail and Deadpool crossover fanfiction?

Itachi and Gray could also have great interactions. Gray is a cool - headed ice mage. When he meets Itachi, they could compare their elemental powers (Itachi's fire - based jutsu and Gray's ice magic). They might also bond over their somewhat stoic personalities and the secrets they both carry.

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.

Definitely Haru and Natsu. They are both hot - headed and full of energy. Their interactions would be really explosive. Haru with his Rave power and Natsu with his Fire Dragon Slayer magic would probably start off by competing with each other in terms of strength, but then realize they need to work together. Another interesting interaction could be between Elie from Rave Master and Lucy from Fairy Tail. They are both strong female characters with different kinds of magic, and they could share their experiences and knowledge about magic.

I think Kakashi and Gray would have some cool interactions. Gray's ice - magic and Kakashi's fire - based attacks (like Fireball Jutsu) could lead to some interesting battles or training sessions. Also, Kakashi and Lucy could be fun. Lucy's celestial spirit magic and Kakashi's summoning jutsu could be compared and contrasted. And of course, Kakashi and Makarov. The old and wise guild master could give Kakashi some unique insights about the Fairy Tail world, and Kakashi could share his ninja wisdom with Makarov.

Deadpool and Iron Man would be really interesting. Iron Man is all about high - tech and calculated moves, while Deadpool is wild and unpredictable. They could have some great banter, like Deadpool making fun of Iron Man's suits or Iron Man trying to get Deadpool to follow some sort of plan.

Erza and Byakuya would be an interesting pair. Erza's leadership and unwavering determination in Fairy Tail, and Byakuya's noble and stoic nature in Bleach. They might initially have a bit of a standoff due to their pride, but as they face challenges together, they would come to understand each other's values and form a mutual respect.

I think Natsu and Ruby would be an interesting pairing. Natsu is all about brute force and his love for fighting, and Ruby has her own determination and speed. They could learn from each other's combat styles. Ruby could show Natsu how to be more strategic with his attacks, while Natsu could teach Ruby how to be more fearless in the face of danger.
