In fanfiction, Ozai's actions towards Zuko can be extremely cruel. Ozai has often been depicted as an abusive father. He burned Zuko's face, which is a very traumatic event for Zuko. In fanfiction, this relationship might be explored further, showing Zuko's struggle to overcome the psychological and physical harm caused by his father.
In 'Ozai Hurts Zuko' fanfictions, Zuko develops by facing his inner demons. The harm from Ozai makes him re - evaluate his life. He might become more empathetic towards others who have suffered, and this changes his outlook on the world. He also gains a new sense of self - identity, separate from what his father wanted him to be.
There could be themes of forgiveness. Zuko might have to grapple with whether to forgive Ozai for all the harm he has caused, given Ozai's new - found love. Also, a theme of self - discovery for both of them. Ozai's love could make Zuko re - evaluate his own identity and place in the family, and vice versa for Ozai.
Yes, there might be some. You can start by checking popular fanfiction websites like Archive of Our Own. Just search for 'ozai loves zuko' in the search bar, and it'll show you relevant stories. However, this is a rather unusual pairing in the Avatar universe, so the number of fics might be limited compared to more common pairings.
One common theme is the power dynamic. Ozai is a powerful figure in the Fire Nation, and how he wields that power over his baby son, Zuko, is often explored. For example, in many fanfictions, he starts to instill in Zuko the importance of strength and power from a very early age.
Obviously, Zuko is the central character as he is the one blessed by Agni. Often, Aang also plays an important role as Zuko's journey with the blessing can intersect with Aang's quest to master the elements and bring balance to the world. Katara might also be involved as she has a complex relationship with Zuko in the original series and this can be further explored in the fanfiction with the added element of Zuko's blessing.
Well, there's a story called 'Zuko's Agni - Given Gifts'. In this fanfiction, the author explores how Zuko uses the blessing from Agni in his fight against the Fire Nation's corruption. It has some really intense action scenes. And then there's 'Agni - Blessed Zuko: A New Path' which shows Zuko's struggle to balance his old self with the new abilities and responsibilities that come with the blessing.
There's also 'Baby Zuko's First Years'. In this fanfiction, it focuses on the early days of Zuko's life with Ozai in the Fire Nation. It explores the different ways Ozai might have interacted with his son during those formative years, like his attempts to mold Zuko into a powerful heir from a very young age.
The 'agni pravesam short story' might be related to the concept of 'agni' which often represents fire in Hinduism. It could be a story that uses the idea of entering the realm of fire (metaphorically) perhaps for purification or transformation. For example, it could be about a person who has to face a difficult trial (symbolized by the fire) and through that experience, they gain wisdom or a new identity. Without more context, it's hard to say exactly what it's about.
I'm sorry, I'm not familiar with the specific 'agni children story'. It could be a story from a particular culture or region that I haven't come across yet.
