Who would be the most interesting characters to focus on in 'Criminal Minds Dexter Crossover Fanfiction'?

I think Grissom from CSI and Reid from Criminal Minds. Grissom is so experienced with the forensic side of things, and Reid is a genius when it comes to profiling. Their interactions would be really cool. They could learn a lot from each other. Grissom could show Reid how to look at evidence in a more practical way, and Reid could give Grissom some insights into the psychological aspects of the cases.

Sasuke and Hotch could be a great pair. Sasuke has his dark and brooding nature, and Hotch is a strong leader. Hotch could help Sasuke with his emotional issues, and Sasuke could show Hotch his powerful ninja skills. They could work together to solve a case where the criminal has a complex backstory similar to Sasuke's own, and they would understand each other on a certain level.

Paige from Scorpion and Reid from Criminal Minds would make an interesting pair. Paige has a way of understanding and communicating with people, and Reid is highly intelligent but sometimes struggles with social interactions. Paige could help Reid better interact with the people they interview during investigations, and Reid could share his vast knowledge with Paige, especially in academic areas like literature and history that might be relevant to cases.

One idea could be that the BAU team from Criminal Minds is called in to investigate a series of murders that seem to have a connection to Dexter's 'hobby'. Dexter, being the secret serial killer who targets other killers, might initially be a suspect. Then, as the story unfolds, they could end up working together to take down a bigger network of criminals that neither could handle alone.

Definitely G. Callen from NCIS LA and Derek Morgan from Criminal Minds. They both have that tough - guy exterior but also a deep sense of loyalty and protectiveness. They could bond over their shared experiences of being in dangerous situations and protecting their teams.

Sherlock and Rossi would have a very engaging interaction. Rossi has years of experience in profiling and investigating, and Sherlock has his unique deductive abilities. They could sit down and exchange stories of their most difficult cases, and perhaps Rossi could offer some insights into the psychological aspects of cases that Sherlock might overlook. And on the other side, the interaction between Sherlock and JJ from Criminal Minds could be interesting. JJ's skills in communication and dealing with the media could play an important role when they are working on a high - profile case together.

Definitely Reid. His brilliant mind and his complex backstory offer a lot of material for a fanfiction. You can explore his relationship with his mother, his eidetic memory, and how all of these aspects affect his work in new and interesting cases.

If it's a crossover with 'Doctor Who', the Doctor would be an amazing addition. His vast knowledge of different cultures and species could help the BAU in cases that have an otherworldly aspect. And his time - traveling ability could add an interesting twist to the story.

Definitely Ben and Ash. Ben with his Omnitrix and ability to transform into different aliens brings a whole new dimension of power and adventure. Ash, on the other hand, has his experience and deep connection with Pokemon. Their interactions would be fascinating. For instance, Ben might be amazed at how Ash can communicate with his Pokemon without any high - tech device, and Ash could be in awe of Ben's alien forms and their powers.

Batman and Black Widow would be really interesting. Batman is all about mystery and detective work in the shadows, while Black Widow is a master spy. They could learn a lot from each other's skills in stealth and intelligence gathering. Also, Thor and Batman could be a great focus. Thor with his god - like powers and Batman with his human ingenuity. Imagine Batman trying to figure out the science behind Thor's hammer while Thor is amused by Batman's determination in the face of the supernatural.
