Who would be the most interesting character pairings in a Gotham and Arrow crossover fanfiction?

Naruto and the Penguin would be an interesting pairing. Naruto's naivete and Penguin's deviousness would create a great contrast. Naruto might try to reform Penguin, seeing the good in him, while Penguin would be constantly plotting against Naruto, creating a lot of comical and tense situations.

For an Arrow - Avengers crossover fanfiction, some really interesting character pairings could emerge. For instance, Malcolm Merlyn and Loki. Malcolm is a master manipulator and Loki is the God of Mischief. They could either team up to cause chaos or be in a constant battle of wits. Also, Cisco Ramon from The Flash (since he often crosses over with Arrow) and Bruce Banner. Cisco could be fascinated by Banner's scientific knowledge and Banner could be interested in Cisco's work on the multiverse. And of course, Quentin Lance and Nick Fury. Quentin, as a police detective, and Nick Fury, as the head of S.H.I.E.L.D., could share their insights on how to keep their respective cities and the world safe.

Oliver Queen and Dean Winchester would be an interesting pairing. Oliver is a brooding, justice - seeking vigilante, and Dean is a tough, monster - hunting badass. They both have a sense of loyalty to their causes and a no - nonsense attitude. They could bond over their shared experiences of losing loved ones and their determination to protect the innocent.

Oliver Queen and Dean Winchester would be an interesting pairing. Oliver is used to leading a team and taking on tough enemies in his city. Dean is a no - nonsense hunter. They could have some great banter and learn from each other's combat and survival skills.

Another interesting pairing would be Captain America and Oliver Queen. Both are leaders with a strong sense of justice. They could have some great discussions about what it means to be a hero and how to lead a team. And when it comes to fighting, they could show off their different combat styles, with Cap's military - trained moves and Oliver's acrobatic and archery - based fighting.

Yukari (from Persona 3) and Chie (from Persona 4). Yukari is very outspoken and has a bit of a sarcastic side, while Chie is energetic and a bit of a tomboy. Their different personalities could lead to some really fun and comical interactions, especially when they're facing Shadows together or just hanging out in the school setting.

Yu Narukami and Joker would be an interesting pairing. Yu is the calm and collected leader of the Investigation Team, while Joker is the charismatic leader of the Phantom Thieves. They could exchange ideas about leading their respective groups and how to deal with the Shadows. Their different fighting styles and Persona abilities could also make for some great team - up moments in battle.

Supergirl and Black Widow would be a great pairing too. Black Widow could teach Supergirl some stealth and espionage skills, while Supergirl could show Black Widow the power of flight and super - strength. They could also bond over their experiences of being different in their respective worlds.

Rachel from Glee and Cisco from The Flash would make an interesting pair. Rachel is very ambitious and talented in music, and Cisco is a tech - genius. They could collaborate on creating some sort of musical - tech device. Maybe Rachel's high - pitched singing could be used to power up Cisco's latest invention, or Cisco could create a device that amplifies Rachel's voice to reach across the city, like a musical - based alarm system.
