supernatural crossover fanfiction

One idea could be that the NCIS team is investigating a series of strange murders that seem to have a supernatural element. They end up calling in the Winchesters from Supernatural for help. The two groups initially clash due to their different methods but eventually learn from each other and solve the case together.

One idea could be that Lucifer from 'Lucifer' enters the world of 'Supernatural'. Maybe he teams up with the Winchester brothers to fight a common enemy, like a new type of demon that is causing chaos in both their realms. He could use his devilish charm and powers in a way that the Winchesters are both skeptical and intrigued by.

One great Merlin - Supernatural crossover fanfic is 'The Hunter and the Warlock'. It combines the magic of Merlin's world with the demon - hunting aspect of Supernatural in a really interesting way. The characters from both shows interact in a believable manner, making for an exciting read.

One idea could be that the Winchester brothers from Supernatural are investigating a series of strange murders in Gotham City. They cross paths with Batman who initially is suspicious of them. Eventually, they realize that a demon is behind the killings and they team up. Batman provides his detective skills and combat abilities while the Winchesters use their knowledge of the supernatural to defeat the demon.

I really like 'Crossroads of Krypton and the Hunting Life'. In this fanfiction, the writers did an amazing job of bringing in the mythology of Smallville and Supernatural. Dean and Sam Winchester end up in Smallville and get involved with Clark's world. It's full of action and some really cool character moments. It shows how the different powers and skills of the characters from both shows can work together or clash in interesting situations.

I really liked 'When Hunters Meet Slayers'. It's a well - written fanfic that does a good job of melding the two universes. It has some great action scenes where Sam uses his research skills to help Buffy and her gang figure out a new type of demon that has emerged, which is a combination of a demon from 'Supernatural' and one from 'Buffy'.

In a crossover fanfic, the angels and demons from Supernatural could be involved in The Walking Dead universe. For example, an angel might be sent to Earth to stop the spread of the undead, believing it's part of a grand plan to save humanity. Meanwhile, the demons could be taking advantage of the chaos, making deals with desperate survivors. The Winchester brothers would have to navigate this new dynamic while also dealing with the walkers.

A popular one is 'Supernatural and Buffy the Vampire Slayer crossover'. This fanfic brings together the two different takes on the supernatural. It has some really cool fight scenes where the characters from both shows team up against common enemies. The story also delves into how the different mythologies of the two shows can co - exist.

One great Supernatural and NCIS crossover fanfiction is 'The Hunt in Quantico'. It combines the mystery-solving aspect of NCIS with the supernatural elements of Supernatural really well. The characters from both shows interact in a very believable way, and the plot keeps you on the edge of your seat.

When writing a Supernatural and NCIS crossover fanfiction, it's important to create a believable setting. You can start by setting the scene in a location that both shows could potentially use, like a military base with a haunted history. Also, think about how the different mythologies in Supernatural, like demons and angels, would be perceived by the more scientific - minded NCIS agents. You'll need to build up the relationship between the characters gradually. Maybe start with some suspicion and then develop into mutual respect as they work together to solve the mystery.
