This action-packed, side-splitting OPM comments on the severe wealth gap, the rise of individuals with no motivation to work, the concept of what I’ll call “power relativity”, and the necessity of jumping through bureaucratic hoops in order to receive due recognition for one’s heroic efforts. Also, a bunch of people get beheaded and someone gets punched in the Gentleman’s Vegetables.
Saitama catchphrase is “I’m just a guy who’s a hero for fun.” For fun, not for fame. So why is Saitama so hurt that no one knows who he is? Well, for one thing, when an army of stolen battle suit-wearing baldies start tearing down buildings (the first one by accident) and the news warns the public to look out for bald people, then it becomes a problem!
That army calls themselves the Paradisers, they’re led by a giant fellow Hammerhead, and they all share a kind of lazy Robin-Hood philosophy of taking from the rich and giving to, well, not just the poor; the poor who don’t feel like working.
Their chief target is the richest man in town, Zeniru, who resides in a skyscraper topped with a golden turd. Unfortunately for the Paradisers, Zeniru has a cocky, smirking ninja named Sonic under his employ.
Battle suits or no, the Paradisers are lower on the food chain than Sonic, who has no trouble lopping the heads off of all of Hammerhead’s comrades, before dodging all of Hammy’s rock and tree-based attacks and throwing a kunai in the back of his head. While
Sonic calls his boss to report his success, Hammy disappears; turns out he has a really really thick skull. And that darned kunai stays lodged in the back that skull for the rest of the episode!
This is not Hammerhead’s day, because he almost immediately comes afoul of Saitama, who is rather pissed off that his “look” has been stolen. Hammy powers up his suit and starts throwing dual paddlewheel attacks, but obviously nothing works against the OPM.
Here’s the thing: Hammy reminds Saitama enough about his past self that he goes easy on him, which means destroying his battle suit with a glancing blow and letting him escape without clothes or his pride, but with his life.
Then Saitama encounters Sonic, who is stronger than Hammerhead, and believes himself the fastest, strongest sonofabitch around who has trained in ninjutsu his entire life…he’s just not as fast or strong as OPM.
Saitama doesn’t really have to exert any effort to neutralize Sonic, and he only neutralizes him accidentally, when Sonic’s junk comes down on his fist (the slow motion shot is priceless). Frankly, Sonic got off easy, as Saitama didn’t put anything into that fist. Yet he considers this encounter a motivator to train harder so that next time they meet, he’ll beat him.
That brings us to Saitama having tea at his place with a recently-repaired Genos, where Saitama expresses his frustration that even after three years of saving various cities from evil villains, no one in either the hero community or the general public know who he is. He doesn’t have a fan club of well-dressed blushing maidens, either.
So Genos brings up Hero Registration, something Saitama didn’t know was a thing, but which he sees as his ticket to recognition. Going online, filling out forms, and showing up to morning exams: it’s the life of a professional, officially recognized hero. Doesn’t sound very fun though, does it?
