Maybe the short girl archer is from a tribe that has an old prophecy related to Robin. She is sent to find him, and when they meet, they have a series of adventures together. Along the way, they face challenges like rival factions trying to stop them from fulfilling the prophecy, and in the process, their relationship develops into a romantic one.
One idea could be that the short girl archer is initially distrustful of Robin because of his mysterious past in the game's lore. But as they are forced to work together on a mission, she sees his true self and they gradually fall in love. For example, during a battle, Robin saves her from a powerful enemy, and that's the turning point.
Another option is to check out Fire Emblem - related forums. There are often threads where fans share and discuss their favorite fanfictions. You could post a request there asking if anyone knows of any good Robin x Short Girl Archer fanfictions. Some well - known forums for Fire Emblem include Serenes Forest.
Maybe the pregnancy is unexpected. Robin and Anna could initially be in denial or scared. Then, as the story progresses, they start to embrace it. The plot could involve them getting support from their friends in the Fire Emblem universe, like Chrom and the other Shepherds. They might also have to face some sort of threat that endangers the pregnancy, creating a lot of drama and tension.
One plot idea could be that Robin and Anna are facing challenges during the pregnancy due to the ongoing war or political unrest in the Fire Emblem world. They have to protect themselves and their unborn child while also dealing with their duties.
One common theme is adventure. They often go on quests together in the fanfictions. Another theme could be friendship evolving into love, showing the development of their relationship.
One common theme is the idea of protection. Robin often takes on the role of protecting the short girl, whether it's from physical danger or emotional harm. For example, in many fanfictions, he might shield her from an enemy attack in battle or comfort her when she's feeling down.
Another option is to look for fanfiction aggregator websites. However, be careful of the legality and quality of the content on some of these sites. On AO3, you can also filter the search results by things like rating, word count, and genre to find the perfect 'Robin x Archer' fanfiction for you.
There's also a fanfiction titled 'A Short Encounter'. In this one, Robin saves a short girl from a dangerous situation. It then delves into their relationship, with Robin being protective and the girl being drawn to his heroic nature. It's a fairly short but engaging read.
One possible plot could be that Robin and Cordelia are in the middle of a war - torn situation in the Fire Emblem world. They discover Cordelia is pregnant, and this news makes them reevaluate their roles in the war. Robin might become more cautious in battle, not wanting to leave Cordelia alone. And Cordelia could be determined to still contribute to the cause while protecting her unborn child.
Another plot could be a story of how Robin and Nowi have to work together to save their comrades during a difficult battle. They learn to trust each other and their relationship deepens as they fight side by side. For example, Nowi could use her dragon powers in a unique way that Robin strategizes around, and through this cooperation, they grow closer.
One idea could be the fusion of the combat systems. For example, Persona characters could use their Personas in a Fire Emblem - style battle grid. Another plot could involve the characters from both franchises getting trapped in a shared, mysterious realm. They would have to combine their unique skills, like the strategic thinking of Fire Emblem characters and the psychic powers of Persona characters, to find a way out. Maybe there could be a plot where a Fire Emblem character gains the ability to summon a Persona, and they have to learn how to control it while also dealing with the political intrigue and battles in their own world.
