One-Punch Man is one of the most popular anime of all time, with the first season sending fans into a fervor as they witnessed Madhouse's stellar animation bringing the series to life in the best way possible. Each and every moment in One-Punch Man is absolutely bursting with personality, with fans being unable to wait for the third season and the vast store of content that is yet to be adapted in the anime.

While the manga of One-Punch Man is definitely quite excellent in its own right — as is to be expected from the brilliant artistic capabilities of Yusuke Murata — there are many people who would stand by the anime as the best way to experience the series. There are several reasons that are cited for the same, with the most popular of the lot being mentioned below.

7 The Animation Is In A Class Of Its Own

If there's one thing that is universally appreciated in One-Punch Man, it's the quality of the animation. Madhouse was in charge of the first season, and the amazing quality of the animation shows that this studio definitely deserves all its plaudits.

It's because of this reason that so many people were upset about the studio changes for Season 2, but J.C. Staff still did a brilliant job on their end for the animation as well. That being said, their work is still far from reaching the quality of the first season, and one can only wait and see how the third season will develop from an animation standpoint.

6 The Fight Scenes Are Absolutely Spectacular

Most of the fights in One-Punch Man mainly serve as a way to show just how ridiculously overpowered Saitama is compared to the rest of the heroes in Japan. Of course, there are some exceptions to the norm, with characters like Genos also engaging in personal battles of their own.

All these fights are shown with pristine detail in each and every frame of the anime, especially in the first season. Even Saitama's dominance ends up being awe-inspiring to witness, with both Madhouse and J.C. Staff pulling out all the stops to show just how destructive Saitama's power really is. A great highlight in this regard is Saitama's "fight" against Genos, where the Caped Baldy shows just how vast and unstoppable his power reserves really are.

5 Mumen Rider's Character Is Has More Development

Most people who've read the manga consider Mumen Rider to be nothing more than a joke character, with maybe a few moments where he gets to shine. However, the anime adds some great scenes that help in the development of this character.

The tender moment he shares with Saitama in the ramen house is one such scene that isn't present in the manga. There's also another great moment where Mumen Rider tries his hardest to console Saitama, even when he himself is scared out of his wits. It's a great way to show how dedicated Mumen Rider is towards saving lives and fighting villains, regardless of his own wellbeing.

4 Some Of The Jokes Are More Impactful

Humor is a subjective topic, and there are certainly going to be many people who will praise the delivery of the jokes in the manga at length. However, there's no denying the fact that the anime features some stellar comedic moments that come to life with the perfect combination of over-the-top voice acting and animation.

The end result is that some scenes in the anime are side-splittingly hilarious in a way that the manga could never achieve. It's one of the major reasons why One-Punch Man became such a massive phenomenon — the comedy of the anime is truly in a class of its own and unlike anything seen in any shonen series.

3 The Action Is Cranked Up To The Max

Most anime adaptations of popular manga tend to tone down the violence and gore of the series, especially if they're booked in a prime time slot. However, One-Punch Man seems to be an exception to this norm — some scenes in the anime are significantly more violent than their manga counterpart.

For example, Mosquito Girl is defeated without a trace in the manga, while the manga shows her dying in a giant explosion of blood. Meanwhile, the death of Crablante is significantly gorier in the anime than the manga, with the former turning it into a grotesque celebration of Saitama developing his resolve to be a hero no matter what.

2 The Adaptation Is Quite Faithful

For the most part, the anime adaptations of most manga tend to follow the source material with maybe a few minor additions or changes of their own. However, One-Punch Man's faithfulness to the manga takes on a whole new meaning altogether.

Readers of the manga will definitely be able to recognize several frames in the anime that are totally similar to the manga, down to the framing and movement of the panels. It's a great way for the animators to give their respects to the amazing artwork of Murata by breathing life into the source material.

1 There's Almost No Filler In The Anime

One-Punch Man is easily one of the most focused and enjoyable viewing experiences that any fan can subject themselves to. This is mainly due to the fact that the anime lacks filler, which is a godsend for fans who hate this meaningless content in their anime.

Some of the best anime ever made have their fair share of haters due to unnecessary filler that ends up bogging down the quality of the show. Thankfully, One-Punch Man managed to escape this trap that most other shonen anime have fallen into.
