Superman v Omniman v Saitama, Who’s The Most Powerful Character? 

Whenever the topic of the most powerful comic book character or superhero comes up, Superman is always going to get a lot of attention. He is one of the most famous after all. However, he is not the only character bestowed with superhuman powers that put him awe-inspiringly close to invincibility – Omniman and Saitama are good examples of this.

Both possess abilities that argue a strong case against Superman’s seeming dominance of the ‘who’s most powerful’ topic. Moreover, each one of them is capable of giving the benevolent Kryptonian a run for his money in a full-contact encounter. However, the question still lingers. Who among these three of us is the most powerful?

To answer that question, we have to take a closer look at these three characters, comparing their strengths and weaknesses against one another. This approach ought to get us to the conclusion that we are looking for. So without further ado, let’s begin.


Superman, one of DC Comics’ most commercially successful superheroes and undoubtedly the most familiar of our three characters is first up. The Man of Steel is oftentimes considered the most powerful character in the DC Universe. However, his amazing strengths have accompanying weaknesses.

Superman’s Strengths

Superman’s powers include the ability to fly, superhuman strength, vulnerability to earthling weapons, and sensory perception that far exceeds that of the average human.

As mist us already know, as powerful as Superman and the rest of the Kryptonians are, they are anything but invincible. Their first and most commonly known weakness is Kryptonite exposure.

Then there are the other deficiencies that some of Clark Kent’s fans might not be aware of like, his weakness against psychical attacks – evidenced during his encounter with Roger Hayden. Aside from that, the Last Son of Krypton is also valuable to Red Sun radiation, electricity, and viruses.

*Superman’s powers have gone through vast changes since the 1930s and have been toned down somewhat in recent times*


Image Comics’ Omni-Man is another super powerful alien who finds himself a resident of Earth, disguised as a best-selling author named Nolan Grayson. Just as with the Kryptonians, he comes from a mighty race known as the Viltrumites.

Omni-Man’s Abilities

Being one of the strongest of the Viltrumites, Omni-Man is able to effortlessly topple large structures, flying many times faster than the speed of sound, and to top things off, he is pretty much invulnerable.


However, the Omni-Man and his Viltrumite kin are not completely indestructible. The race of high-powered aliens happens to have a weakness in the inner ear.  It plays a major role in how they fly and can be manipulated in order to destabilize them – or even cause direct injury.

Furthermore, The Viltrumites are also not impervious to the teeth of the Ragnar aliens, which can easily shred even their strongest individuals. Lastly, Omni-Man and all other Viltrumites are susceptible to the “Scourge Virus”, a bio-weapon that is tailored to target the race of super-beings.


Lastly, we have Saitama from the Anime series, One Punch Man. This time our insanely powerful character is not a wandering being from another galaxy. Instead, Saitama is a “Superhero for fun” who is said to have gained his immense strength through a rigorous training schedule. However, there are constant hints to how that might not be all there is to it.

Saitama’s Strengths

Saitama possesses a level of physical fitness and confounding strength that makes him the strongest individual in his universe. To put this into perspective, Saitama is able to beat most of his opponents with a single punch. In terms of his speed, he passed a physical examination by clearing 1500m in an instant.

Saitama is also quite resilient. He has survived the vacuum of space a few times and completed atmospheric re-entry unscathed. To add to this, Saitama’s grueling training regime somehow gave him resistance to psychical attacks.


To date, Saitama has never fought using the full potential of his strength and he generally just seems godlike. That said, this man has no known weaknesses.

The showdown of Superman, Omni-Man, and Saitama

All our characters have their set of strengths and weaknesses, making them questionable. Especially in the cases of Superman and Omni-Man.

However, when it comes to Saitama, the absence of known weaknesses tips the scale awkwardly in his favor. Nevertheless, that is not to say that an encounter with either one of the superbeings from space would push him to the limits of his abilities and possibly expose one of his unknown weaknesses. For now, though, Saitama seems to be the strongest contender.
