Well, the Criminal Minds team would approach the situation with their standard procedures. They would interview Teamiplier members as part of their investigation. Teamiplier, on the other hand, would probably be more eager to jump into action. They might crack jokes during tense moments, which could either relieve the stress for the BAU team or annoy them at first. But over time, they'd learn to work together, like when they face a common enemy or mystery.
One idea could be that the BAU team is called in to investigate a series of strange disappearances that seem to be related to a haunted location that Teamiplier has explored in one of their videos. The two groups initially clash due to their different approaches, but then they start to work together and combine their skills to solve the mystery.
Well, Spencer Reid from Criminal Minds would probably be fascinated by the technology from the Stargate universe. He'd be constantly asking questions and trying to understand the scientific principles behind it. Meanwhile, Colonel Jack O'Neill from Stargate might find Reid a bit of an oddball at first, but would grow to respect his intelligence.
The serious and cerebral profilers from Criminal Minds might initially clash with the more action - oriented SWAT team members. For example, Reid from Criminal Minds might seem overly intellectual and reserved to some of the SWAT guys who are used to more straightforward communication. But over time, they could learn from each other. The SWAT team could teach the Criminal Minds agents about physical combat and quick - response tactics, while the agents could help the SWAT team understand the psychology behind criminals they face.
Scott McCall would probably be very cautious around the Criminal Minds team at first. He's used to keeping the werewolf secret. But when he realizes they're there to help solve a problem, he might open up. Spencer Reid, on the other hand, would be extremely curious about the werewolves. He'd likely bombard Scott with questions. Derek Hale might be more standoffish, seeing the BAU as outsiders in his world. And Hotch would be trying to keep order and figure out how to work with these new, very different individuals.
Often, the FBI agents from Criminal Minds are initially skeptical of the supernatural elements that the Supernatural characters deal with. For example, Hotch might be very hesitant to believe in the existence of ghosts or demons at first. But as the story progresses, they start to see the evidence and have to work together with the Winchester brothers.
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.
Hotch from Criminal Minds could be very interesting. He's a strong leader and his no - nonsense approach would contrast with Dexter's more secretive and morally ambiguous ways. Their interactions could be intense, like when Hotch starts to suspect that Dexter is not what he seems. Hotch would try to use his profiling skills to figure out Dexter, while Dexter would be trying to outwit him to protect his secret.
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.
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.
