One idea could be that an alternate - universe version of Superman comes to their world. This could lead to a power struggle as both Supermen have different ideas on how to protect the city. Another plot could involve Lois getting superpowers temporarily and having to learn how to use them while also dealing with her regular reporting job.
Well, a great plot could be centered around a new villain who targets both Superman and Lois specifically because of their relationship. This villain could be from another dimension and has a vendetta against the concept of a superhero - human relationship. It would force Superman to protect Lois while also trying to figure out the villain's motives and weaknesses. Also, maybe there could be a storyline where Superman loses his memory and Lois has to help him regain it while also keeping his identity a secret from the public.
One idea could be that their daughter discovers a new power she inherited from Superman but struggles to control it at first. For example, she might accidentally cause some chaos in school when her emotions run high. Another plot could involve her trying to find her own identity separate from being Superman and Lois' daughter. She could go on a journey of self - discovery, maybe even leaving Smallville for a while to explore the world on her own terms.
One idea could be exploring how they balance their superhero and normal lives while preparing for the baby. For example, Superman might have to deal with villains while also making sure Lois is safe during her pregnancy. Another could be a story where Lois discovers some new super - power related to her pregnancy, like being able to sense danger to the unborn child.
A really interesting plot could be that an alternate - universe version of Superman comes to their world. This causes some confusion for Lois as she has to figure out which Superman is the one she truly loves. Meanwhile, the two Supermen have to work together to fight a threat that endangers both their universes and their relationship.
One idea could be that Superman and Invincible have to team up to stop an alien invasion that threatens both their worlds. The two heroes could initially clash due to their different methods but then learn from each other.
Here's an idea. There could be a powerful magical artifact that surfaces in both cities. It has the power to change reality. Superman, being a man of science, is initially skeptical about its power. Batman, on the other hand, has seen enough strange things in Gotham to know it's dangerous. They have to overcome their differences in beliefs as they race against time to stop different factions in both cities who want to use the artifact for their own gain. Along the way, they also learn more about each other's worlds and form a stronger bond.
One idea could be that Superman gets transported to the Marvel universe during a freak interdimensional event. He teams up with the Avengers to fight a common enemy like Thanos, who has somehow obtained Kryptonite. Their combined powers and different strategies would make for an epic battle and an interesting exploration of how the two universes' heroes interact.
One idea could be that Superman has to balance his superhero duties while also being extra protective of Lois during her pregnancy. He might use his powers in new and creative ways to ensure her safety and comfort. For example, he could create a special force field around her when she's out in public.
A superman crossover with Wonder Woman would also be great. Maybe in a story where they have to travel to another dimension to stop an ancient evil. Their different powers and personalities would create a lot of interesting interactions, like Superman's more down - to - earth (even though he's from another planet) approach compared to Wonder Woman's Amazonian heritage.
One idea could be that Superman and Wonder Woman have to team up to stop an ancient alien threat that is immune to their individual powers. They must combine their strength, speed, and wisdom to find a way to defeat it.
One idea could be that a powerful new villain emerges who has the ability to manipulate both Batman and Superman's minds. This forces them to fight against each other while the real enemy is pulling the strings. Another could be a situation where Gotham and Metropolis are in a territorial dispute, and Batman and Superman initially take sides based on their cities, but then realize they've been played.
