Perhaps the pregnancy is a result of some sort of alien experiment gone wrong. Lilo and Stitch then have to find a way to reverse it if they don't think they're ready for a baby. But as time goes on, they start to warm up to the idea and decide to keep the baby, facing all the difficulties and joys that come with it.
One idea could be that Stitch gets transported to another dimension where he meets characters from a different animated universe. They could team up to fight a common enemy that threatens both their worlds. Another plot could involve Lilo somehow getting superpowers and joining Stitch on an intergalactic adventure to save other planets. Maybe they encounter a race of beings who are trying to steal the unique bond between Lilo and Stitch to use for their own evil purposes.
Well, perhaps there could be a fanfiction where the Grand Councilwoman from Lilo and Stitch discovers the Pokemon world. She decides to send Stitch there on a mission to study the Pokemon. Stitch then forms a team with some Pokemon like Charmander and Squirtle, and they have to face off against an evil organization that wants to use Pokemon for bad things. It would be a fun mix of the two universes.
One idea could be a crossover where Lilo and Stitch end up at Hogwarts. Stitch could get into all sorts of mischief with the Marauder's Map. Another could be that Harry Potter somehow ends up on Lilo's island and has to deal with the local magic there which is different from his own. And perhaps Dobby could meet Stitch and they form an unlikely friendship.
One idea could be about Stitch learning new Hawaiian traditions with Lilo and her family. For example, they could be preparing for a big luau together, and Stitch has to master a particular dance or cooking technique.
A possible plot could be that there is some kind of prophecy or special event related to their baby. Stitch and Angel have to figure out what it means and how to ensure the safety of their unborn child. Along the way, they encounter old friends and foes who either help or hinder them. The story could also explore how their pregnancy affects the entire community around them, whether it's other experiments or the people on their planet.
In the 'Lilo and Stitch short story', it's often about the relationship between Lilo, a little Hawaiian girl, and Stitch, the alien. Stitch causes various mischiefs but Lilo accepts him for who he is. They go on adventures around their island, and through their bond, Stitch learns about family and love.
One interesting aspect is the exploration of the unique bond between Lilo and Stitch. In non - adult fanfiction, it can be delved into more deeply, like how they support each other through various challenges on their island. Another aspect is the expansion of the other characters' backstories. For example, we can learn more about Nani's struggles as a young caretaker. Also, the cultural elements of Hawaii that are so prominent in the story can be further explored and celebrated.
Perhaps in the fanfiction, there's a new alien virus in Hawaii and all the 'experiments' including Stitch need to get special shots. Stitch doesn't want to at first because he's afraid it will change him. But Lilo convinces him that it's for the greater good of the island and their friends.
Well, the plot could involve Naruto being somehow transported to the world of Lilo and Stitch. Maybe he teams up with Lilo and Stitch to fight off some new villains that are threatening their island. Naruto's ninja skills would be really useful in that kind of setting. He could teach Lilo some basic self - defense moves, and Stitch could use his super strength and crazy abilities to help Naruto out in battles against any bad guys from Naruto's world that might show up.
Well, usually they are very cute. They focus on the pure and innocent relationship between Lilo and Stitch. The kisses are often used to show deep affection in a non - sexual way.
