One idea could be a behind - the - scenes look at the friendships and rivalries among the stars in the 'house of stars'. For example, exploring how two actors who seem to be friends on the surface are actually competing for the same big role.
One idea could be exploring a different path for the main characters. For example, if they met under different circumstances, like at a different event or in a different kingdom. This could change the initial dynamic between them.
A time - travel plot in a Precure All Stars fanfic could be really cool.

An interesting plot for a Transformers Battle Stars fanfic could be a competition between the Autobots and Decepticons. Not a battle, but a race to complete a series of challenges on a newly - formed planet. The winner would get exclusive rights to the planet's resources. This would force the two factions to use their skills and intelligence in different ways than just fighting. Another plot could involve a human - like race that the Transformers encounter. The Transformers have to decide whether to protect this race or use them for their own ends, which causes internal conflict within both the Autobot and Decepticon ranks.
One idea could be to explore a new mystery in the House of Anubis. Maybe a hidden chamber is discovered that has ancient artifacts and secrets related to Anubis.

For example, they can communicate with spirits in the house that hold important information about the past.
One idea could be that the characters discover a hidden room in the Creepypasta House filled with old portraits that seem to come alive at night.

Or perhaps there's a mysterious diary in the house that reveals dark secrets about the previous owners and it seems to have a curse attached to it.
Another plot could involve a love triangle among the Loud siblings' friends. They all end up at the Loud House often, and the love triangle causes some tension. But through various events at the house, like parties or family outings, they start to understand each other better and resolve their differences in a really sweet way.
Perhaps in the 'We were boxing the stars fanfic', there could be a tournament among different star - related beings. Each has their own unique boxing style, and the main character has to learn from different cultures in the stars to compete. They might face a powerful opponent who seems unbeatable at first, but through determination and some newfound skills, they have a chance at victory.
One idea could be a redemption arc for a previously disliked character. Maybe they team up with an unexpected ally and prove themselves in a series of challenges that are different from the ones in the show, like underwater maze races. Another could be a love triangle between three of the all - star contestants that causes drama both on and off the challenge field.
