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.

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

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.

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 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.

The similarities between these anime are endless. Happy-go-lucky protagonists, evil villains who might aswell have been in the opposite series, their personalities, the humor they share. The series as a whole really remind me of one another and give a very similar vibe.

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 BoyHime732
Both based on original web comics by the same creator ONE. Both have very similar art styles, character designs and senses of humour. Both have received two seasons of anime adaptations. Both see their main character struggle with the excess of their own powers. 
report Recommended by JVskunkape
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!

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.

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. Both series will give you greatly animated action scenes that will glue your eyes on the show each episode. Overall, One Punch Man and Kekkai Sensen are action-packed shows set in places filled with weirdness sprinkled with plenty of comedy.

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. The character design is also somewhat similar, especially the first villain that Saitama faces, who looks like a blue Piccolo.

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.

Not as great as character development as one piece does. BUT, one piece is one of a kind. No serie out there that I've seen comes near the adventureous and unique story of one piece.

Both series have a protagonist that have a completely different attitude from the rest of the characters and don't really fit with the setting. 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.

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.

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.

While both shows are very different in terms of story, genres, and setting, the core plot remains the same. Both shows have a protagonist that is viewed upon by most people around them based solely on their social status that was given to them under a sort of ranking system like a review board; which was created with several inadequate fatal flaws that fail to categorize them properly. And yet, everyone blindly accepts that review board as if it was the only one truth, not unlike how many see the Holy Bible; while refusing to see past those previously mentioned flaws and only seeing what  read more

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.

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. Both are hilarious.

I might change this later when I re-watch OPM, but believe it or not, both of these series are relatively similar comedically. In order to fully appreciate both of these animes, you have to understand satire and how both OPM and Kaguya roast a lot of cliches in their respective genres. This is especially highlighted by the fact that Furukawa Makoto plays the MCs for both of them LOL (Saitama in OPM and Kaichou Shirogane in Kaguya).

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.

Both anime use common tropes that are present in other works of the same genre as their foundation, in order to expose and make fun of them (OPM uses tropes from the superhero genre, while TTGL uses tropes from the super robot genre). Both shows have a similar type of humor and over the top action scenes. They are self-conscious shows that try to be entertaining and are not meant to be taken seriously. They also create a similar atmosphere and vibe.

Both series show similarities in main character and there story. Comedy is kinda similar also.

Both are episodic, monster-of-the-week series about super power users, both with skeletal main plot. Both contain some fanservice, and both are intended parodies of the 'it's so stupid it's hilarious' kind. Both explore single joke for most of their run. While their underlying jokes are completely different, both series hinge upon one finding the joke good enough to sustain their attention for the whole 12 episodes.

Both anime have a very strong main character, who is trying to find strong opponents, but usually ends up defeating them easily (although their reasons for doing so are not the same). They also have a similar sense of humor and supernatural abilities.

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.
