One Punch Man once redefined epic action scenes for the anime community, but now, Season 3 is under fire on social media for unacceptable mistakes. The backlash isn’t just about a drifting storyline but also how key moments were handled, turning what should have been epic sequences into memes and a nightmare of quality control.
1. Garou’s Movements Look Unnatural in Season 3
Garou was supposed to feel like a predator in Season 3. In the manga, every move he makes is sharp, aggressive, and calculated. Yet throughout the season, most of his movements appear stiff and lack fluidity.
For example, when Garou moves, he seems to slide across the screen lifelessly instead of taking realistic steps. His footwork lacks weight and smooth transitions between attacks. Instead of smooth animation, the scene relies heavily on still frames and camera tricks, creating a terrible first impression for a martial arts master like Garou.
2. Atomic Samurai’s Hair Bun Disappears Mid-Scene
Some animation errors can be debated, but this one is undeniable. In one episode, fans noticed Atomic Samurai’s hair bun completely vanished in a shot. It wasn’t due to injury or story reasons, it just disappeared.
This small slip-up stands out in a show known for sharp character designs and reveals a rushed production process. It’s not a stylistic choice or redesign but a cleaning error that slipped through final edits, marking a clear sign that Season 3 was racing against the clock.
3. Royal Ripper’s Gender Mistake Causes Confusion
Another moment involved Royal Ripper, where the show accidentally changed the monster’s gender. In episode 3, Royal Ripper, clearly male in the manga, briefly appears with distinctly feminine features and a different body shape.
This fleeting mistake was quickly spotted by fans and sparked shock and memes. Although a simple animation error, letting such a clear slip into an episode shows how carelessness and tight schedules severely hurt Season 3’s quality.
4. Mizuki’s Six-Fingered Hand Goes Viral Online
Blink and you’ll miss it, but the internet did not. In episode 7, during the fight with Captain Mizuki, a frame briefly shows her hand with six fingers instead of five.
This episode already faced criticism for stiff animation and too many still images. It also featured another odd visual error where Mizuki had an unintended chest detail. Episode 7 reads like a checklist of mistakes that should have been caught by quality control.
5. Orochi’s Introduction Feels Rushed and Underdeveloped
Orochi was meant to be a major character. In the manga, his introduction carries weight, tension, and a strong sense of threat. But in Season 3, that impact is greatly diminished. The scene moves too fast, leaving little time to understand who Orochi is or why he matters. The same goes for several Monster Association members around him.
While minor dialogues tend to drag on, the main villains are introduced hastily with quick scene changes, making the pacing feel off. For manga fans, this was a missed chance to truly showcase the scale and terror of the upcoming battle.
