Both series have the same sense of humor and absurd, comedic art packed with high amount of action in each episode, portraying how strong the protagonist is compared to the rest of the characters.

Both are hero animes and while One Punch Man is already strong, the character around him are similar to those in Boku no Hero Academia. They both feature a lot of different heroes and their daily struggle. One Punch Man is a little darker in tone and if you want a strong protagonist from the get-go, try saiki kusuo no Ψ-nan or psycho mob 100 !

These are both light hearted comedic shows with similar senses of humour, neither show takes itself too seriously. Both MC's are ridiculously over powered, and decide to focus on the downsides of having such power.

The first thing I thought when watching Overlord, it's very much like One Punch Man. Overlord and One Punch Man got similar style while having different setting. You can tell the anime would be similar as their openings are similar style music. The main characters Momonga/Ainz and Saitama are also extremely strong, but not OP lame, they're strong that you want to see them go in FOR THE KILL !!!!! Dependable heroes.

Where will you go if all your dreams have been fulfilled? That is the question that both series deal with. They don't have a serious plot, just the daily life of a man who is trying to live his life. There are battles and funny moments sometimes. Recommend to people who are looking for some funny anime to watch to add some spice to their life.

Both have protagonist with simple mentality that are more strong that the rest of characters, their words have people with powers and the shows are full of comedy. 
report Recommended by VDenazmimi
The protagonist in both shows is extremely strong. But they don't take the responsibility seriously, and end up talking about regular stuff in the middle of a fight that's supposed to be intense (like shop sales) which leads to comedy in both shows. If you liked the atmosphere in one show, you will most likely like the other show.

A modernised and commercialised / 'business' approach to the concept of superheroes existing in our world. Heroes are ranked based on points awarded AND subtracted for their actions in the line of duty. Public relations - mainly in terms of popularity - is also a factor. Every self-respecting hero needs a fan club, after all! In One Punch Man it is less important since it is more of a cartoonishly over the top series with hero rankings as window dressing, where as in Tiger & Bunny the entire plot is built around 'idol culture' televised heroics. But they are the only two series I have come  read more

Protagonist is OP to ridiculous level which brings absurd situations and proper steamrolling of opponents. Sure, one is super hero parody, other is powerfantasy in fantasy setting. Both are kinda cheeky and not taking themselves seriously... and come on, the last battle in Misfit of DK Academy made laught so hard!!! And its comparable to the last fight in OPM in its sheer ridiculousness.

Both shows are filled with relentless action and a lot of comedy moments. The fights are over the top and flashy as possible. Also fights defies any logic or physics laws. The common part of both show is a cast of colorful and meaningful characters. The biggest difference, however, is the amount of fanservice. KLK is full of it, while OPM has it really low.

Both follow a very similar plot: the hero is OP. There is even a fairly similar villain in the anime, though I do have to say I feel that both are kind of mainstream in terms of how far anime goes. If you enjoyed one of these anime, you'll probably enjoy the other one.

For the simple comparison in terms of doing an "overpowered" character right. In terms of entertainment, the cast of characters, supporting or main, world and the building of the said world, and story progression, yeah it pretty entertaining. 
report Recommended by Alufei
When you watch a story, you want to see its hero struggle right? But sometimes, there are those stories where the hero fighting isn't the struggle, it's the world around him. Inferno Cop and Saitama never have to worry about losing a fight, but the absurd ways that the world treats them is what drives the humor and wonder of these shows. 
report Recommended by IzzyHime
The protagonist definitely reminded me of Saitama from One Punch Man. Strong but oblivious and nonchalant about his strength and helps other characters along the way who become interested in him due to his strength. 
report Recommended by Aleron
They are both comedic stories that follow an overpowered "first hero" that has defeated the greatest monsters of the world, leading to the development of a Hero Association to manage heroes that protect the world from evil. These heroes are categorized into letter rankings based on assessments of their power. Our protagonists start off at extremely low ranks despite having overpowered abilities. I'll just say it. Hero's Return (Yingxiong Zai Lin) is pretty much just a donghua (Chinese animation) rip-off of One Punch Man. If you look closely, Saitama even appears as an easter in one of the mob/crowd characters of Hero's Return.

They both have two Hilarious main characters who are both OP and trying to find a more challenging opponent to match up with their skills. Koro Sensei is trying to find a student who can kill buy the time his students graduate and Saitama after realizing he is too strong is getting bored of killing villains with One punch so in the end he is still trying to find a challenging opponent. Both Stories are VERY good and action packed. Also Saitama and Koro-Sensei are both teachers. They're both great shows to watch!

Both anime focus on a very strong protagonist, who usually defeats his enemies with ease. They have a lot of action and fights, but also a lot of lighthearted comedic moments.

Both share the same rare anime theme of superheros, but Zetman takes a darker and more serious perspective on it with a more concrete story. The action is explosive on both ends and the main characters for each don't really care for a lot of things. The anime also share in having enemies that are more on the strange side.

One Punch Man and Hataraku Saibou are story about certain groups that doing their job to save "the world". Immune Cells = Heroes Viruses, Bacterias, etc. = Monsters Both have serious action scenes as well as comedy scenes. In One Punch Man, the story is mostly focused on Saitama, the overpowered hero. While in Hataraku Saibou, it's more like "Hero of the Day". However, the plot is different. Hataraku Saibou is an educational story about how cells work, while One Punch Man is a story about Heroes.

The similarity of these anime is not on their plot or characters; it is in the quality of their animation. If you enjoyed the fluidity and the awesomeness of either series on your screens then the other is a must watch.

Overall, One Punch Man and Kekkai Sensen are action-packed shows set in places filled with weirdness sprinkled with plenty of comedy.

Great action, funny, awesome fight scenes. Overpowerd characters, cool attacks etc. And if you're liking the animation in One piece, try One punch man.

Both are parodies of shounen battle anime featuring arcs and characters poking fun of stereotypical cliches seen in such anime series. Sexy Commando is mostly pure comedy and gags however, where One Punch Man actually does have somewhat serious action and a stronger focus on fights. Both are hilarious and entertaining. Also, both feature an inexplicably powerful and quirky protagonist that makes the rest of the characters seem laughably incompetent in comparison, even though you root for them anyway.

Both series involve overpowered protagonists that you end up rooting for regardless, due to the shows' abilities to focus on minor characters and their growths alongside the MC. As well as this, both protagonists kinda involve some sort of progression that you get invested in; with Slime you end up rooting for Rimuru's village's growth; with One Punch Man you end up rooting for Saitama's recognition in the Hero Association. All fights are full of hype- especially the ones where you know that the protagonist wins, and acts as catharsis when you see the villain finally get beat up.

While these two anime have different settings, both of them are not made to be taken seriously. The protagonist in both titles uses extraordinary powers to defeat powerful monsters. Both anime are hilarious to watch with cool characters and awesome action scenes. However Hell Teacher Nube has horror elements and is a way older than One Punch Man. If you don't mind watching older anime, if you like one then you may enjoy the other as well.

Both share a similar sense of humor - irreverent parody of old action shows - and are consistently funny. Both have OP main characters. The main differences are their secondary genres: One Punch Man has cool fight scenes, while Love After World Domination has a cute romance and is ecchi-er. One Punch Man has prettier animation, but I find the animation quality of LAWD to work well with its humor.

As shown in the MHA series before, the "one for all" quirk becomes stronger every time it's passed down. Saitama also known as "the One punch man" probably has that nickname because of his ridiculously strong punches. So this gives me the sentiment of that One punch man is MHA in the future with Saitama having inherited the One for all quirk. If my theory is right, you should at least relate to One punch man if you like MHA. But you can also differentiate the two easily.

Both series parody common troupes in their respective genres. OPM makes fun of superhero shows like My Hero Academia and Bishounen is quite literally an attack on Ouran Koukou Host Club with Monogatari-like directing; heck Bishounen makes fun of its sister series of Bakemonogatari. Specifically, One Punch Man jokes about Gary Stus and 'bringer of justice' type characters while Bishounen attacks the male and female stereotypes of Ouran Koukou Host Club with fanservice parody, 'handsome vs. beautiful' nonsense.

Like Saitama, Vash the Stampede is an enigma who is extremely skilled compared the vast majority of fighters (not super OP like Saitama though), but is almost misunderstood by everyone. If you like Saitama, you will almost definitely like the way Vash fits in with his respective universe as well.

Although their setting and mood are different (with OPM being a comedy and HnK being more tragic), both anime focus on an overpowered main character, who kills enemies almost effortlessly. Both have great art and over the top action.

Both of these have a protagonists who keeps going by his own flow, not much bothered by others. Well, also both are bald.

Main Similarities: •Bad guys come, the main character deals with them. •Both main characters in the anime are very strong. •Similar plot/setting. •Similar-ish genres.

Both gag/parody JUMP series. Both feature immensely over powered main characters who's own powers become hinder-some and a source of distress for our heroes.

Tomoko really look and act like Saitama, strange physic, weird smiles etc ... Both of them are strangers to their environment, and are not recognized as they should be

Believe it or not, both these animes have things in common. Kinnikuman and One Punch Man are both satires to the "hero" ideology. Both series start with their protagonists trying to protect the world from monster attacks but both Kinnikuman and Saitama are underlooked by society. While Kinnikuman starts as a weak superhero but further progresses through the story and Saitama is already overpowered from beginning to end, both series feature over the top action, comedy, manliness, muscles, violence and friendship.

Overpowered main character. Absolutely ridiculous and over-the-top fight scenes, with plenty of budget and explosions. Entertaining and diverse characters. Solid comedy amidst the action. Main character punches things and they die in glorious fashions.

The main characters in both shows are OP and have mysterious past and how they acquired their powers. Casshern Sins is the opposite of OP Man for the following Reasons: -Underrated to OP Man's Overratedness -Darker and Grittier tone to OP Man's Light and Goofy tone -Casshern is more emotional as opposed to Saitama's lazy demeanor Both shows are produced by Madhouse and if you enjoyed one or the other, watch it.

It is hilarious and entertaining and a parody of shounen. Sound, characters and art is nice. The whole package is good and if you loved Hayate no gotoku! then you will certainly enjoy one punch man.

The rope of humor where the heroic good OP character is misunderstood and looked over, and that same character being somewhat obtuse.

The two battle shounen I have enjoyed the most in two different moments of my life. Ueki no Housoku was part of my childhood, and One Punch Man introduced me to anime series again after years. They both share a simple and funny main character with a strong sense of justice.

Like one punch man has a hero association hunter x hunter also has hunter association They both have main characters who are kinda overpowered - saitama for OPM and killuas family for HxH. Both have characters who struggle more in fights than others. Both protagonists are searching for something - a worthy adversary for saitama and his father for Gon. The only main difference between them is that HxH is a bit darker than OPM.

Both appear to have a mix of different aspects such as robots, aliens, superpowers and superheroes. Both portray a society where these things are common place.

When I watch OP Man, I thought of Saitama being the shonen version of Dante due to the various reasons: Both being OP and having countless victories, mysterious past, partnership with another powerful beings, They are isolated and will always be no matter what, and They are involved in various missions involving various people. Both anime have an episodic story line and fast paced action. I find DMC to be starkly contrasting to OP Man due to the dark tone and goriness. OP Man beats DMC in terms of popularity, story, character development, and media Nuff Said

One Punch Man and Yugioh GX have a powerful main char who wins in many battles but faces bad reputation from haters but do not mind their public image. JAM project does the opening in both shows as well.

Both have beautifully animated fights. While OPM's fights are more about scale and impressiveness, Sword of the Stranger puts more of a focus on fight choreography.

Both extremely popular "Hero" anime that focus on a world with Heroes, Villains and super powers. Both have a main character who is or will be the strongest hero. Both have amazing OSTs, animation and characters. Both have very similar world building with both having Hero associations and increasingly dangerous villains.

Both series are action heavy and feature intense, over the top fights against often surreal looking enemies. Contrary to One-Punch Man, Gantz is played serious and is a lot more violent however. People who enjoyed the fight scenes of One-Punch Man more than they did its humour might find more of what they're looking for in Gantz.

Both the main characters are dumb and are super hero, and both have loyal disciples. And both series are comedy.

Each MC (I'm going to go with Spike and Satiama) are both laid-back and nonchalant Villans can be quite ridiculous and outrageous, which I find to be a nice plus The series themselves are episodic, but are excellent comedies

both series have a nice battle scene. each series have comedy side in their story. but Akame story more suspenseful than OPM that have more comedic side.

Both use physical comedy and have similarities with their senses of humour. Both are "Hero" anime with high intensity action scenes, yet more of a focus on the series' comedy and characters. Both OST's and art styles are amazing.
