While most anime characters desire more strength and worry about defeat, the only problem in Saitama’s life is that he can’t find a worthy opponent. It’s just a punch, and his enemies are dead. And most of the time, this punch doesn’t need to be serious.
One Punch Man is about to get its third season, and Saitama has yet to find an opponent with whom he can test his full potential. But being the most powerful character in the One Punch Man series doesn’t mean Saitama is unbeatable. There are few anime characters who can crush him easily.
10/10 Anos Foldigwad (The Misfit Of Demon King Academy)
Annus is a demonic lord formerly known as the King of Demon Tyranny. The only time Anus was defeated was when he gave up his life for a bigger cause. Then he reincarnated into the magical age two thousand years later. Anos even defeated the gods of his universe, making him the most powerful being ever.
His level of power is terrifying, and he can destroy planets, solar systems, and multiple universes with one hit. Once, he moved the moon with his hands to make an eclipse of the sun, and in another case, he raised an entire castle and turned it with his index finger. Given Anos’ strength, Saitama might not even be considered a worthy opponent.
9/10 Rimuru the Storm (that time I reincarnated as an episode)
Do not go to his innocent face. Rimuru Tempest is one of the strongest anime characters who can easily defeat Saitama. Saitama can handle enemies in hand-to-hand combat with ease, but what about an enemy with magical powers? The list of Rimoru’s powers is endless.
Even if Saitama is able to deliver a punch to Rimuru, Rimuru has the ability to regenerate damage quickly. Since he can stop time easily, Saitama has no chance to fight against him. Once Rimuru froze time, he could use his many other magical powers to defeat Saitama.
8/10 Ryuk (Death Note)
Fighting does not just mean exchanging kicks and punches. Sometimes it’s as easy as picking up a death note and a pen and writing the name of your enemy. There is virtually nothing Saitama can do against Ryuk, the god of death. Since he can’t touch it, he can’t use his signature move, Serious Punch, against Ryuk.
As soon as Saitama’s name is written in the notebook, it disappears. The reason we chose Ryuk instead of Light is because if they were both standing against each other, Saitama wouldn’t give enough time to raise his pen.
7/10 Baraggan Louisenbairn (Bleach)
Baraggan Louisenbairn is one of the main antagonists of the popular anime Bleach. He is a member of Aizen’s army, and his formidable spiritual powers can easily defeat Saitama. The deadliest ability he can use against Saitama is Senescencia, as he can slow down time near him.
It doesn’t matter how fast Saitama is; Once Baraggan Louisenbairn uses this technique, Saitama will become very slow. Another feature of this attack is that Baraggan can spoil anyone he touches by aging in an instant. So, even if Saitama could match his physical strength, he wouldn’t stand a chance against his mystical powers.
6/10 Zeno (Dragon Ball Super)
Not only could Zeno from Dragon Ball Super defeat Saitama, he could put an end to everyone in the world of One Punch Man. He is the god of the multiverse and he is so powerful that he can wipe out the entire universe with a single thought. If Saitama angered Zeno, he could kill him without even raising his hand.
Some of you may be wondering: What if Zeno had to fight him, keeping this power aside? Well, Saitama still doesn’t have a chance, because Zeno is immortal. Therefore, even if Saitama used all his strength, he wouldn’t be able to inflict any significant damage on him. Since Zeno can easily emulate anyone’s ability, he can fight it off by becoming anything he wants while remaining immortal.
5/10 Line
We pit Saitama against various powerful humans and even gods. Now, let’s compare it to a computer program. Lain is an omnipresent and omnipotent being who has complete control over the real world and The Wired. In simpler terms, she can manipulate the entire universe as it seems to her.
Lain is not your usual anime character who would show off her power to show her dominance. In fact, she would be less interested in fighting Saitama, and even if she did, it wouldn’t be fair to call it a fight because we would only witness one-sided torture. She can manipulate time, manipulate all the information in Saitama’s head, and even just erase his existence.
4/10 Viren (Umineko when they cry)
Umineko is definitely a lesser known series but it features some very strong anime characters, and Featherine is one of them. She is a sorceress who acts as a master of many games, and the level of her strength exceeds the universe. Just like Lain, Featherine also has the power to manipulate the universe.
Her only known weakness is the crescent-shaped memory device on her head, which helps her retain knowledge about her appearance, personality, memory, and primarily herself. So, the only way for Saitama to steal victory is to destroy her memory device, but she is unlikely to let him get close to him.
3/10 metronome (a specific scientific accelerator)
Saitama is the angel of death for most of his opponents, especially when he gets serious, but that’s the problem while facing the Accelerator – the more Saitama serializes, the greater the threat to his life because the Accelerator’s ability allows him to get rid of his opponent’s ability back to them with more force.
As seen in the recent One Punch Man chapters, Saitama first becomes serious and destroys Jupiter, making him a planet-wide threat. But, the Accelerator is a universe-wide threat in its final form. The same could be said of his defenses.
2/10 Antiviral (Tengen Toppa Gurren Lagann)
While Saitama fights against threats to his city or at most, threats to Earth, antivirus and the beings of his tribe fight those who pose threats to the entire universe. The Antispiral is hard to understand, but you can consider it the supreme being that has been there since the creation of the universe.
Calling Saitama a worthy opponent would be a disgrace to Antispiral, given their pious characteristics. It is difficult to differentiate between cosmos and antivirus because they have been around since the beginning. From manipulating the mind to simulating force, time travel, and erasing existence, there is literally nothing antivirals cannot do.
1/10 Heaven Ascension Dio (JoJo’s Bizarre Adventure)
He is the main antagonist of Eyes of Heaven in Jojo’s Bizarre Adventure and comes from an alternate world. As a result of achieving his goal of obtaining heaven, he became the owner of divine powers that far surpassed Saitama’s power in every sense of the word. Heaven Ascension Dio is a well-known character in the manga but has not been a part of the anime adaptation yet. You can enjoy the character in Jojo’s Bizarre Adventure: Eyes of Heaven.
Now, let’s talk about some of his awesome powers that Saitama wishes he would never encounter. Dio is now able to erase a person or the entire reality if he so desires. Even if Saitama tries to throw a serious blow at him, Dio can stop time to dodge the attack. Even if he could hit, Dio could instantly regenerate. Mind manipulation, lightning attacks and teleportation are some of his other awesome powers.
