What are some interesting plot ideas for a TVD and Riverdale crossover fanfiction?

One idea could be that a strange meta - human from The Flash's world somehow ends up in Riverdale. This meta - human has the power to manipulate memories, and starts causing chaos by making the Riverdale characters forget important things about each other. Archie and his friends then team up with Barry Allen to stop this meta - human before their town is torn apart.

A cool concept would be a joint mission. The Supernatural side has to deal with a powerful, ancient evil that has some connection to the vampire origin in the TVD world. So, they team up. Dean might be initially hesitant about working with vampires like Stefan and Damon, but they soon realize they need each other's skills to defeat this new threat.

In some 'Riverdale Crossover Fanfiction', a crossover with a time - travel plot is really engaging. For example, when the Riverdale gang travels back in time to the 1950s and has to deal with the different social norms while also trying to get back to their own time. Also, crossovers with other teen drama shows where they have to compete in a singing or dancing competition together can be quite entertaining.

Archie Andrews and Elena Gilbert could also be a fascinating pairing. Archie's all - American hero - type personality and Elena's role as the central figure in Mystic Falls' supernatural drama could create an interesting dynamic. They could be drawn to each other as they both have a strong sense of protecting their friends and family, and they might have to rely on each other's unique skills when facing a common enemy that threatens both Riverdale and Mystic Falls.

Well, perhaps it's a case of mistaken identity. A new character in Riverdale is kidnapped instead of the intended target, who was thought to be Archie because of his popularity. This could lead to a series of events where the other characters have to race against time to find the kidnapped person before it's too late. They might discover new secrets about the town and its inhabitants during the search.

Well, one interesting plot point is the clash of the different vampire abilities. In Twilight, vampires have certain powers like super speed and strength, and in TVD, vampires have different powers like compulsion. When combined in fanfiction, seeing how these powers interact or conflict can be really exciting. For example, if a Twilight vampire tries to use their speed against a TVD vampire who can compel them, it creates a whole new dynamic.

One idea could be that they face challenges from the vampire and werewolf communities. Since their relationship was already complex in the show, this pregnancy could stir up more trouble. Another plot could be them trying to keep the pregnancy a secret while preparing for the arrival of the baby. They might have to deal with issues like finding a safe place to raise the child in a world full of supernatural threats.

Well, a possible plot is that Elena's pregnancy is the result of a spell gone wrong. Klaus, despite his initial shock, decides to stand by her. This could lead to a series of events where they have to fight off those who see the baby as a threat. It could also explore how Elena deals with the physical and emotional changes of pregnancy while being in a rather strange relationship with Klaus. And the baby might have some unique abilities that are both a blessing and a curse.

One idea could be a male oc who is a new student in Riverdale. He has a mysterious past related to a big city crime syndicate. As he tries to fit in at Riverdale High, he gets involved with the core group of friends. Maybe he has some special skills like being an expert in martial arts or a whiz at hacking, which he uses to help solve the town's mysteries. Another plot could be that he is an aspiring musician who gets caught up in the drama between the music clubs at school and the local music scene in Riverdale. He could also have a romantic sub - plot with one of the female characters, like Betty or Veronica, but there are obstacles in their relationship due to his secrets.

One idea could be that the characters from Riverdale somehow find themselves in the wizarding world of Harry Potter. Maybe Jughead could be a Muggle - born wizard who discovers his powers while at Hogwarts. He might write about his strange new experiences in his journal, just like he does in Riverdale.
