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 of the best Zod stories is his conflict with Superman in 'Man of Steel'. General Zod is a Kryptonian military leader who wants to terraform Earth into a new Krypton. His intense battles with Superman are epic, showing his strength and military tactics.
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.
Well, General Zod is obviously a main character. He's the driving force behind most of the plots. And Superman is another key character as he is often in direct opposition to Zod. Lois Lane also plays a role as she is often caught in the middle of their battles and is a connection to the human side of the story.
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.
