Alec from Shadowhunters and Castiel from Supernatural. Alec is a loyal and by - the - rules type of person, while Castiel is an angel who often doesn't fully understand human ways. Their interactions could be really fun as they try to understand each other's motives and goals while fighting side by side.
Castiel and Paige Matthews could also make for a great pairing. Castiel's otherworldly, angelic nature and Paige's half - witch, half - white - lighter abilities would lead to some unique interactions. They might struggle to understand each other at first, but as they learn more about their respective powers and purposes, they could form a strong alliance to combat a powerful enemy that neither of their worlds could handle alone.
Definitely Dean Winchester and Oliver Queen. Dean's rough - and - tumble, no - nonsense attitude combined with Oliver's brooding and strategic mind would make for some great banter and action scenes. They could bond over their experiences of losing loved ones and their determination to protect the innocent.
Definitely Barry and Dean. Barry's positive attitude and scientific mind would contrast well with Dean's tough - guy, no - nonsense hunting style. Another interesting pairing could be Iris and Sam. Iris is a strong - willed journalist, and Sam is the more intellectual and empathetic Winchester. And then there's Cisco and Castiel. Cisco's love for creating new tech and Castiel's otherworldly nature would make for some really fun interactions.
Alucard and Dean Winchester would be an interesting pairing. Alucard's dark and brooding nature, combined with his overpowering abilities, would contrast with Dean's more impulsive and human - centered approach.
Definitely Tony Stark and Dean Winchester. Tony with his high - tech gadgets and smart - aleck attitude, and Dean with his love for classic cars and no - nonsense approach. They would have some really interesting banter, and Tony could probably learn a thing or two about survival from Dean, while Dean might be impressed with Tony's technology.
Definitely Piper and Dean. Piper's power to freeze time could be really useful when Dean is in a tight spot during a hunt. And Dean's no - nonsense attitude could balance out Piper's more emotional side.
Definitely Clark Kent and Dean Winchester. Clark with his superpowers and strong moral code, and Dean with his tough - as - nails hunting skills and loyalty. They could have some great banter as they come from such different worlds but find common ground in protecting people. Another interesting pairing could be Sam Winchester and Chloe Sullivan. Sam's intelligence and knowledge of the supernatural could pair well with Chloe's investigative skills.
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.
Magnus Bane and Doctor Strange would make a great pairing. They are both powerful magic - users. Magnus could introduce Doctor Strange to the magic of the Shadow World, and Doctor Strange could share his knowledge of the mystic arts from the Marvel Universe. They could collaborate on spells and magical defenses against common enemies.
Ladybug and Deku would be a great pairing. Ladybug is a strategic and powerful leader in her world, and Deku has his own unique way of analyzing situations and his determination. Together, they could share their knowledge about combat and heroism. Deku could learn from Ladybug's experience with magic - based powers, and Ladybug could learn about different Quirks from Deku.
