Generally, Omni-Man is stronger. He has superior physical abilities and a longer history of using his powers effectively. However, Invincible has shown potential to catch up over time.
Sure. Invincible's journey in the comics sees him continuously evolving and getting stronger. Eventually, he outpaces Omni-Man, but it's not an easy or straightforward path. There are many challenges and setbacks along the way.
The Invincible System of Man vs. Wild was a novel in which the protagonist transmigrated into the game world of Man vs. Wild. In this game, the main character's island did not have any system support, but the player's continent had a system. The protagonist could increase his strength by hunting and eating meat, bypassing the system settings. The novel described the protagonist's survival in the wilderness.
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.
The third season of Man vs. Wild was a documentary with Bear Grylls as the main character. In this season, Bell would travel to the toughest and most desolate places on Earth to demonstrate his unique survival techniques and show the audience how to survive in such an environment for a week. Bear Grylls, a survival expert who had served in the British special forces, was parachuted into various harsh environments, such as rainforests, deserts, hills, and ice fields, with only simple tools. The camera team recorded his entire survival process. Bell used all kinds of survival skills, including determining directions, finding water, and obtaining food. The third season of Man vs. Wild had a total of 10 episodes and could be watched online.
