One interesting plotline could be the characters sharing their backstories in the group chat that were never fully explored in the original show. For example, Klaus might talk about his experiences in the afterlife in more detail.
Another plotline could be the siblings planning a prank on Reginald through the group chat. They could come up with elaborate schemes while chatting back and forth, like Luther suggesting they all pretend to lose their powers at once just to see his reaction.
Five is also a favorite. His intelligence and no - nonsense attitude can lead to some intense and interesting exchanges in the group chat. He might be the one to quickly solve a problem or come up with a strategic plan for the group.
One interesting plotline could be Allison and Luther trying to reconnect after years of being apart due to the chaos in their lives. They might start by sharing memories of their childhood in the Academy that they had long forgotten. For example, they could recall a particular training session where they had to rely on each other to complete a difficult task. Another plotline could involve them facing a new threat together and having to use their unique abilities in harmony. Allison's power of rumor manipulation and Luther's super strength could combine in unexpected ways to defeat the enemy.
A unique plotline could be Klaus training a new group of people with powers similar to his. It shows his growth as a character from being a bit of a mess to someone who can mentor others. This often involves him sharing his own experiences and how he learned to control his powers better.
In some fanfictions, there could be a plot where the two groups have to team up to fight a common enemy. The Umbrella Academy's more organized and superhero - like approach could clash with the Misfits' more haphazard and street - smart ways. This contrast can create a lot of interesting storylines, like how they strategize or how they deal with each other's personal issues during the mission.
One idea could be creating an OC who has the power to manipulate time in a different way than Five. For example, they can freeze time for specific objects or people while the rest of the world continues as normal. This would add a new dynamic to the Umbrella Academy's adventures and interactions with the timeline.
One interesting Klaus fanfiction could be about his journey to fully control his powers. In this story, he might meet a mentor figure who helps him understand the true extent of his abilities to communicate with the dead. It could show his growth from being a somewhat chaotic character to someone more in control.
One interesting story could be about the characters' post - apocalyptic adventures in an alternate timeline. It might explore how they deal with new powers and relationships. Another could focus on their backstories in more depth, like how they grew up before the events of the show. And there could be a fanfiction that delves into a romantic relationship between two of the characters that was only hinted at in the original series.
One interesting story could be about the characters' reactions to a new time - traveling villain. In this fanfiction, the Hargreeves siblings might initially be divided on how to handle the threat, leading to some intense in - family drama.
Another great crossover could be with 'The Boys'. In this scenario, the Umbrella Academy would be thrown into the world of corrupt superheroes. They would have to navigate the complex politics and power plays while also trying to stay true to their own values and not get caught up in the dark side of superhero - ism.
One idea could be exploring what would happen if a new member joined the Umbrella Academy. Maybe a time - traveling superhero from the future who has knowledge of a great threat coming. Another could be a story where the members lose their powers and have to rely on their wits and teamwork in a completely different way. For example, dealing with a powerful enemy who can nullify powers.
