One idea could be that they face challenges in a world not fully accepting of their relationship and impending parenthood. Their friends might have mixed reactions, and they have to work together to prove that their love and their new family can be strong. For example, Aang could be initially worried about how this would affect the balance in the world, but then come around to support them.
Their relationship could also face new strains. With the responsibilities of a baby coming, they might argue about things like where to raise the child, what values to instill. But at the same time, these challenges could also bring them closer as they work through their differences. For example, Zuko might want the child to be raised in the Fire Nation, while Toph wants an Earth Kingdom upbringing. Through these discussions, they learn more about each other's hopes and fears.
Yes, there are quite a few. You can try searching on popular fanfiction websites like Archive of Our Own. There you might find some well - written stories about Toph and Zuko sharing a kiss, with different plotlines and character interpretations.
A possible plot could be that Toph and Zuko are forced into an arranged marriage by their families or kingdoms for political reasons. Then, Toph gets pregnant unexpectedly. This leads to them having to figure out their relationship on a deeper level. They start to bond over the pregnancy, sharing their hopes and fears for the future. Maybe they go on a journey to find a special place where they can raise their child in peace, away from the politics and power struggles that surround them.
In a 'Zuko meets Toph' fanfiction, they might start off on the wrong foot. Zuko's serious and brooding nature could clash with Toph's brash and independent attitude. Maybe they get into a small fight at first, but then gradually come to respect each other as they realize they both have a strong sense of justice. For example, they could team up to take on a group of bandits that are causing trouble in a village.
During the pregnancy, Zuko might start to explore his softer side more. He could become more nurturing, learning how to take care of Toph and preparing for the baby. He might also become more protective, using his firebending skills to ensure their safety. Toph, on the other hand, could develop her maternal instincts early. She might use her earthbending to create a safe and comfortable environment for the baby, like building a special room or a small garden. As she goes through the physical changes of pregnancy, she also becomes more in tune with her emotions and the emotions of those around her.
