You could start with a character from one side being in a situation that requires the help of the other group. For instance, in a crossover with 'Power Rangers', if one of the Angels gets caught in a monster - infested area that the Power Rangers usually protect. This forces her to seek their help, and then the two teams start to work together, with each bringing their own unique skills and strengths to the table.
Begin by establishing the setting and the problem that will bring the two worlds together. If it's a crossover with 'Sherlock Holmes' (in a modern adaptation), maybe there's a series of art thefts that both the Angels and Sherlock are investigating. Outline the main characters' personalities and how they will react to each other. The Angels are used to a more action - based approach while Sherlock is more cerebral, so there could be some interesting clashes and collaborations.
First, decide which other franchise or story you want to cross over with. Then, think about how the characters from both will interact. For example, if it's a crossover with 'Ocean's Eleven', consider how the Angels' style of operation differs from Danny Ocean's crew. You can start with a simple scene like the Angels getting a mysterious call that leads them to cross paths with the other group.
First, decide which two (or more) universes you want to cross over. For example, if it's 'Weeping Angels' and 'Harry Potter', think about how the two concepts can interact. Then, create a basic plot. Maybe the Weeping Angels are attracted to the magic in Hogwarts and start targeting students. Next, start with an interesting opening scene. You could begin with a student seeing a strange statue (which is actually a Weeping Angel) in the Forbidden Forest.
One idea could be a crossover with the 'Mission: Impossible' series. The Angels could team up with Ethan Hunt's crew to take on a powerful international criminal organization. They could use their different skills, the Angels' charm and combat abilities along with the high - tech gadgets and espionage skills of the Mission: Impossible team.
Begin by establishing the setting clearly. If it's a Joker crossover with a horror universe, describe how Gotham starts to take on elements of that horror world. Then, introduce the Joker in a way that makes sense in this new context. Maybe he's intrigued by the new horrors or sees an opportunity to create more chaos. You also need to consider the characterizations and how they will interact. The Joker's maniacal nature might clash or blend in unexpected ways with the other characters.
First, decide which universe or character you want to crossover with Morbius. For example, if it's Iron Man, think about how their worlds collide. Maybe Morbius' condition attracts the attention of Stark Industries. Then, create an interesting opening scene. It could be Morbius in a situation that leads him to cross paths with Iron Man, like a strange energy signature that both are investigating.
Begin by choosing the right crossover. Let's say it's Negan and 'Harry Potter'. Think about the rules of the 'Harry Potter' world and how Negan would break or bend them. You can start with Negan somehow getting a letter from Hogwarts (maybe a mistake by the owl post). He shows up at the school, and chaos ensues. Write from his perspective as he encounters magic for the first time. His confusion and his attempt to assert his dominance in this new and strange place would make for an interesting start.
Well, start by creating a scenario that brings the Jashin concept into the other story. For example, if it's a crossover with a game world, think about how Jashin's influence could disrupt the game's balance or create new quests. You could also think about the reactions of the original characters to the Jashin - related elements. Maybe they're horrified, or maybe some are intrigued. Then build your plot around these interactions and reactions.
First, choose the two universes you want to cross over. For example, if it's Miraculous and Naruto. Then, think about how the characters will interact. Maybe Ladybug could learn some ninja skills from Naruto. Start with a simple scenario like an akuma attack in a world where ninjas exist.
First, decide which universe you want to cross Chappie over with. For example, if it's "Terminator", research the lore of that universe. Then, think of a plot hook. Maybe Chappie is mistaken for a Skynet creation in the Terminator world. Next, start writing an introduction that sets up the crossover situation.
First, decide which universe you want to crossover with. Then, think about how the Mandalorian's character traits will interact with the new universe's elements. For example, if it's a crossover with Star Trek, consider how his no - nonsense attitude will mesh with the more diplomatic Starfleet officers.
First, decide which two universes you want to cross over. Then, research both of them thoroughly. Know the rules, the characters, and the settings.
