Omni-Man vs Optimus Prime Winner: Omni-Man Omni-Man's experience, power, and speed were too much for Optimus Prime. Despite the Autobot's intelligence, skill, and weapons, he was no match for the centuries-old Viltrumite. Omni-Man's strength was unparalleled; he had destroyed an entire alien planet with a single punch. His endurance was remarkable, too, as he had survived a nuclear bomb and fought off an alien invasion. His speed was unmatched, and he had traveled across the universe in mere moments. In contrast, Optimus Prime's speed was quite slow, and he could only transform into a truck or a robot. Omni-Man's fighting experience was another factor that helped him win against Optimus Prime. With a bloody fighting record of 100000000000, he was a killing machine, having brutally defeated the Guardians of the Globe. In contrast, Optimus Prime had experience mostly dealing with the Decepticons in limited environments. Omni-Man's skills as a fighter were also notable. He had the agility and reflexes to dodge attacks from Optimus Prime's weapons while also delivering blows powerful enough to knock the Autobot off his feet. His fighting style was quick and efficient, honed over centuries of combat. In comparison, Optimus Prime relied heavily on his weapons, making him predictable. Finally, Omni-Man's strength, speed, and fighting skills allowed him to overpower Optimus Prime's lazer attack and slice through his energon swords and battle axe with ease. Though Optimus Prime was tough and durable, Omni-Man's power was just too much for the Autobot's armor to handle. Thus, in the end, while Optimus Prime fought valiantly, it was Omni-Man's superior strength, speed, fighting experience, and skills that won the day.
