Yes, Zuko did have a crush on Katara in the comic.
It would likely become more complex. They would have to rely on each other more as parents. Their love might deepen as they share the experience of raising a child together.
Some fanfictions explore their role in rebuilding the world after the war. Zuko and Katara could be working together to restore balance between the nations. This kind of fanfiction often shows their leadership skills and how they complement each other.
Their relationship would likely become more intimate and complex. They would have to rely on each other more, sharing a bond that goes beyond their previous friendship or alliance. Zuko would probably become more protective of Katara, and Katara would trust Zuko with her vulnerability during pregnancy.
One great Katara and Zuko fanfic is 'The Balance Within'. It beautifully explores their relationship development post - war. It shows how they learn to understand each other's perspectives and grow closer as friends and maybe more. Another is 'A New Alliance' which has an interesting plot where they team up for a mission that forces them to rely on each other and in the process, their feelings start to shift.
One great 'Zuko and Katara Fanfiction' is 'The Phoenix and the Wave'. It beautifully explores their relationship development. The story is set in a post - war scenario where they have to work together on a diplomatic mission. Their initial distrust slowly turns into mutual respect and something more.
No, they don't. There's no such scene in the comics.
Well, it could be a story about how they navigate parenthood in a world filled with political unrest. Maybe they have to protect their baby from those who oppose their union.
One possibility could be that the baby becomes a symbol of unity between the Water Tribes and the Fire Nation. Since Katara is from the Water Tribe and Zuko is from the Fire Nation, their child might grow up with a unique ability to bridge the gap between the two cultures. Maybe the story could focus on how they raise the baby in a world that is still recovering from the war, teaching it about both water bending and fire bending heritage.
Zuko and Katara's love story begins with animosity. However, Zuko's change of heart over time makes Katara see him in a new light. Their bond forms through mutual respect. For example, when they face common enemies together. Katara realizes that Zuko is not the same person he used to be. And Zuko is drawn to Katara's strength and kindness. Their love grows slowly but surely as they support each other in difficult times.
In some fanfictions, Katara might hurt Zuko physically during a fight. For example, if they have a misunderstanding and their elemental powers clash, Katara's waterbending could accidentally strike Zuko and cause him harm.
