A more character - driven plot could explore a relationship between Faora Ul and Superman that goes beyond their initial enmity. For example, they could be stranded on an uninhabited planet together. At first, they are wary of each other, but as they struggle to survive, they start to understand each other's motives and beliefs more deeply, leading to a new kind of bond.
Another plot could be a time - travel fanfic. Faora Ul and Superman are sent back in time to Krypton before its destruction. They have to work together to prevent the cataclysm that will end their home planet. This would involve them dealing with Kryptonian politics and the complex society there while also trying to figure out how to change the fate of Krypton.
Well, Superman has his super strength, heat vision, and flight. Faora Ul is also very strong and a skilled fighter. One way their powers could be combined is in a battle scenario. Superman could use his flight to quickly move Faora Ul to different strategic positions during a fight. Then Faora Ul could use her combat skills up close while Superman provides support with his heat vision from a distance.
Some fanfictions might focus on how Lois Lane helps Superman deal with the public perception of him in the 'Man of Steel' universe. She could be writing articles that shape the way people see him, either positively or negatively, which would be an interesting take on their dynamic.
One idea could be that your original character (OC) is from another planet similar to Krypton. They arrive on Earth and initially clash with Superman over different approaches to protecting the planet. But as they face a common powerful enemy, they learn to work together and combine their unique powers.
One idea could be that Catwoman steals a valuable item and Superman is tasked with retrieving it. But as he chases her, he realizes she has a noble reason for the theft, like helping the poor in Gotham. So, instead of simply arresting her, he decides to help her find a legal way to achieve her goal.
One idea could be exploring what would happen if Clark Kent from Smallville met the more established Superman from Man of Steel earlier in his journey. Maybe they could team up to face a common threat that neither could handle alone.
The story of 'Superman: Man of Steel' is about Clark Kent, who is Superman. He is an alien from Krypton. As he grows up on Earth, he discovers his superhuman abilities. He has to face the challenges of hiding his true identity while also protecting the world from threats. For example, he battles General Zod, who is also from Krypton and wants to terraform Earth to make it like Krypton.
Superman: Man of Steel tells the origin story of Clark Kent, a.k.a. Superman, as he discovers his powers and decides to use them to protect Earth from various threats.
Another plot idea could be to put her in a situation where she has to team up with her enemies to face a greater threat. This would force her to set aside her differences and learn about her foes on a more personal level, leading to character growth for both her and the other characters.
Well, you could focus on a love story set within the 'a tale of blood and steel' world. For example, a warrior from one side falling in love with a healer from the opposing side. Their relationship would be full of challenges as their factions are at odds. Or, you could write about a young apprentice who discovers a dark secret about the ruling class in the 'a tale of blood and steel' and has to decide whether to expose it or keep it hidden, knowing that either choice could have dire consequences.
One idea could be exploring the backstories of the different shipgirls in more depth. For example, how they came to be and their experiences before joining the fleet.
