In some lego pirates fan fiction, there are stories of pirate ships with unique abilities. For example, a ship that can fly or become invisible. The crew uses these special features to outwit their enemies and explore uncharted seas.
Anne Bonney - like characters are also quite popular. Female pirates add an interesting dynamic. They are often shown as being just as tough, if not tougher, than their male counterparts. They are skilled in sword fighting and have a sharp mind for strategy.
Captain Redbeard is quite popular. He is often depicted as a fearless leader with a big heart. His crew trusts him completely.
One interesting storyline could be an alternative version where Ned Stark survives. This would completely change the power dynamics in King's Landing and how the various houses interact. It might lead to a more stable rule under the Starks, or it could spark new rivalries as other houses feel threatened by Ned's newfound power.
In some fan fictions, Arya might have an encounter with the Faceless Men again, but this time not as a student but as an equal or even a leader. She could use their skills to take on a powerful and corrupt regime in Westeros.
In Lego Friends Stories, there might be a story where the friends go on an adventure to find a lost treasure. They use their different skills. For example, one might be good at reading maps, another at climbing. Along the way, they make new friends and also have to outwit some sneaky characters who also want the treasure. It's a story full of excitement and friendship.
Another possible storyline is that Dany and Jon have to deal with the political aftermath of their relationship. There could be opposition from different houses who don't want a Targaryen - Stark union. They would then have to navigate through the complex web of politics, with Dany using her dragons as a show of force when necessary, and Jon using his diplomatic skills learned from the North. This would be a story full of intrigue, power plays, and of course, their undying love for each other.
One interesting storyline could be about a young Jedi in training who discovers a hidden power within the Lego Star Wars universe. This power could help him face the Sith in a unique way.
One interesting storyline could be Joker devising a new, elaborate plan to take over Gotham City that involves some wacky and unique traps. Batman, of course, has to use his Lego - themed gadgets and skills to stop him. Another could be a story where Joker and Batman are forced to team up against a greater threat, like a powerful alien invasion in the Lego universe. Maybe they start to understand each other a little better during this time.
Some lego fan fictions focus on the backstories of the lego sets. For instance, a fan fiction about a lego castle could explore the history of the castle, the wars that were fought there, and the different families that ruled over it. It might tell the story of a young knight minifigure who is trying to restore the glory of the castle after it has been damaged in a battle.
