A great plot could involve a powerful and ancient curse that affects both the Supernatural world of angels and demons and the more magical world of Constantine. The curse is causing strange phenomena like people seeing visions of the apocalypse and magic going haywire. Sam, Dean, and Constantine must find the source of the curse, which could be an old, forgotten artifact. Along the way, they face off against enemies who want to use the curse for their own gain, and they have to overcome their differences in approach to solve the problem.
Well, Dean Winchester is very head - strong and impulsive. Constantine, on the other hand, is more of a sly and calculating character. Their personalities could clash when it comes to decision - making. For example, Dean might want to charge into a fight right away, while Constantine would prefer to plan things out more carefully. But they could also blend well. Constantine's cunning could help the Winchesters in situations where brute force won't work, and Dean's loyalty and determination could inspire Constantine to be more committed to a cause.

The fics usually revolve around the characters trying to figure out these mysteries and stop the threats.
Finally, write with passion and let your creativity flow. Use vivid descriptions to bring the supernatural elements to life. For example, when describing a demon, don't just say it's scary.
