Dean Winchester and Daryl Dixon would make an amazing pairing. Dean's tough - guy attitude and his skills with weapons combined with Daryl's survival skills in a post - apocalyptic world would be really cool to see. They could go on zombie - hunting trips together while also sharing stories about their pasts.
Castiel and Glenn Rhee would also be a great combination. Castiel's angelic powers could be used to protect Glenn as he tries to scavenge for supplies. Glenn could introduce Castiel to the concept of community and survival within a group, which is very different from Castiel's usual experiences in the Supernatural world.
Michonne and Sam Winchester would be a great pairing too. Michonne is a skilled fighter with her katana, and Sam is very intelligent and well - read. They could work together to research any possible links between the walkers and the supernatural. Sam could also help Michonne come to terms with any new, otherworldly threats they encounter.
I think Cortana and Michonne would be an interesting pairing. Cortana has all this knowledge and intelligence, while Michonne is a fierce fighter. Cortana could provide strategic advice to Michonne, and Michonne could teach Cortana about the realities of survival in a world full of the undead. They could form a really unique bond.
Definitely Rick Grimes and Captain America. Rick is a natural leader in a world full of zombies, and Captain America is a symbol of leadership and justice in the Avengers world. They could share their leadership experiences and strategies to fight against the combined threats.
Sasuke and Daryl could be a really cool pairing. Sasuke's brooding nature and his powerful ninja skills along with Daryl's hunting and tracking abilities in a post - apocalyptic world. They might start off as rivals but eventually work together. For instance, Sasuke could use his Sharingan to detect hidden threats while Daryl uses his crossbow to take out zombies from a distance. And they could have some deep conversations about their past traumas and how they've coped with them.
Sam Winchester and Daryl Dixon would be a great combination. Sam is intelligent and resourceful, and Daryl is a skilled tracker. They could share their skills and knowledge to survive in the zombie - filled world while also looking for a way to stop any supernatural forces at play.
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.
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.
