There could also be a fanfiction where Diego and Klaus get transported to an alternate universe. In this new world, they have to find a way back while also dealing with versions of their siblings that are very different. This would be an exciting adventure that tests their bond and forces them to adapt quickly.
Perhaps a story where Ben, despite being a ghost, finds a way to physically interact with the world for a short time with Klaus's help. They could then use this opportunity to right some wrongs or have experiences they missed out on when Ben was alive. This could involve things like going to a concert or helping a person in need.
Their powers are very different, Diego with his ability to manipulate knives and Klaus with his ability to communicate with the dead. This contrast creates an interesting dynamic in fanfiction as they can complement each other's skills. For example, Klaus might get information from the dead that helps Diego in a fight.
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.
A possible plot idea is that Klaus discovers that his ghost - seeing ability is not just a random power, but part of a much larger, supernatural plan. The ghosts he sees are actually messengers from a different dimension, and they are trying to guide him to save both his world and theirs. Also, the fanfiction could explore a plot where Klaus' relationship with a particular ghost deepens into a strange friendship. This ghost has the ability to enter the dreams of the other Umbrella Academy members, and Klaus has to use this to his advantage to solve a mystery within the academy. Or, there could be a story where the ghosts start to disappear one by one, and Klaus has to race against time to find out what is causing it and stop it before he loses his connection to the spirit world completely.
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.

It really depends on the author's take, but generally, it's a relationship full of love and the struggle to be together given all the obstacles in the Umbrella Academy universe.
