General Zod and Doomsday are not the same. General Zod is a Kryptonian villain with his own distinct traits and motives, while Doomsday is a powerful and destructive creature. They have different origins and storylines in the comic universe.
One idea could be a battle in an alternate dimension where the laws of physics are different. This would force both Superman and Omni - Man to adapt their fighting styles. Another could be a scenario where they are forced to team up against a greater threat first, before their own conflict resurfaces.
It's hard to say for sure. Omni - Man has incredible strength and combat experience. However, Superman has near - invulnerability and his powers are powered by the sun. If the fight takes place on Earth, Superman has the home - field advantage with the sun constantly recharging him. But if it's a long - drawn - out battle, Omni - Man's tenacity could also be a factor. In my opinion, Superman's powers are more diverse and powerful, so he would likely come out on top.
One great 'Young Justice General Zod Fanfiction' is 'Zod's Ascent'. It shows General Zod arriving on Earth in the Young Justice universe and his attempts to conquer it in a really unique way. The author does a great job of portraying Zod's power and his military - like strategies.
One frequent theme is redemption. Some fanfictions attempt to give General Zod a chance at redemption. They might show him being influenced by the Young Justice team's ideals of justice and heroism, and slowly changing his ways. Also, the theme of leadership is common. Zod is a natural leader, and fanfictions explore how his leadership style clashes or meshes with the leadership in the Young Justice universe.
In fanfiction, Bardock and Omni - Man are often combined in interesting ways. Bardock is from the Dragon Ball universe, known for his sacrifice. Omni - Man from Invincible has his own complex character. In fanfics, they might be pitted against each other in battles of strength. This can lead to exciting scenarios where their different powers and personalities clash. It also allows for exploration of how their respective moral compasses would interact in a fictional crossover.
