Let’s look at a specific scene: Ben turning into Feedback for the first time.
The new dub treats Ben as an over-the-top shonen hero, similar to Monkey D. Luffy or Asta from Black Clover. This tonal shift has divided purists but has attracted a massive new anime audience.
The hashtag #ベン10新吹替 (#Ben10NewDub) trended on Twitter (X) following the premiere. Japanese fans have praised the "speed" of the dialogue. One user wrote:
"I hated Omniverse before because the jokes felt slow. But the new Japanese dub fires jokes like a machine gun. It feels like Gintama for kids."
Another commented:
"Khyber speaking like a serious samurai hunter makes him terrifying. Why didn't they do this ten years ago?"
Criticism is minimal, though some older fans miss the "nostalgic" feeling of the 2013 cast. However, the consensus is clear: the new Japanese dub of Ben 10 Omniverse is superior.
In the bustling district of Shinjuku, Tokyo, a small, windowless studio hummed with the quiet intensity of creation. On a large monitor, the vibrant, angular world of Ben 10 Omniverse played on a loop—Alien X-Tinction, Malware’s metallic rasp, Rook’s stoic calm. But the audio was raw, unpolished English.
Seated at the mixing desk was Kenji Saito, a veteran voice director known for turning Western cartoons into Japanese cultural touchstones. His latest mission: the Japanese dub of Ben 10 Omniverse—not a re-release, but a new production. A fresh cast. A new translation. A reimagining.
“It’s not just about replacing words,” Kenji muttered to his assistant, Mika. “The old dub was fine. But this? This is Omniverse. The energy is different. Faster. More anime.”
Mika nodded, scrolling through a tablet. “The network wants it to feel like a shonen battle series. They’re even calling it BEN 10: Ginga no Omocha—‘Ben 10: Toy of the Galaxy.’” ben 10 omniverse japanese dub new
Kenji smirked. “That’s a little on the nose. But I like the spirit.”
The first auditions were a disaster. Veteran actors tried to mimic the original English voices—too gruff, too silly, too American. Kenji stopped every session. “No. Stop copying. Find the essence.”
Then came sixteen-year-old Haru Aoyama. Small for his age, with messy black hair and a hoodie two sizes too big, he read for Ben Tennyson. No hero pose. No exaggerated swagger. He just leaned into the mic and said, casually:
“Yo. Omae no ichiban no aite wa... kono ore da.” (“Yo. Your worst enemy right now... is me.”)
The room went silent. It wasn't a translation of a Western catchphrase. It was a Japanese delinquent-hero line—half confident, half playful. Kenji leaned forward.
“Again,” he said.
Haru delivered again, but this time after a long, bored sigh. The contrast was perfect. This wasn’t a kid who wanted to be a hero. He was a kid who was one, and it annoyed him slightly.
For Rook Blonko, Kenji chose Takumi Nagase, a soft-spoken theater actor who played Rook as deadly serious but endearingly literal—like a polite exchange student who could also throw a Proto-Tool punch. The chemistry between Haru and Takumi during their first table read was electric. When Ben joked and Rook didn’t laugh, the silence became the punchline.
The real challenge came with the aliens. Each transformation needed a distinct voice, but Kenji wanted consistency. “Four Arms isn’t just loud,” he said. “He’s frustrated—like a sumo wrestler in a phone booth.” He had Haru record all of Ben’s aliens himself, pitching and modulating his voice in post. The result was strange and wonderful: every alien felt like a different facet of the same chaotic soul.
Months passed. Episodes were recorded, mixed, and scored with new background music—rock guitars for fight scenes, taiko drums for alien transformations. The network executives were nervous. “Too different,” they said. “Fans of the original dub will hate it.” Let’s look at a specific scene: Ben turning
Kenji held a private screening for a group of middle schoolers—the target audience. They laughed at Rook’s deadpan reactions. They cheered when Ben first transformed into Feedback, electricity crackling in 5.1 surround. One kid whispered, “This is better than My Hero Academia.”
The day of the broadcast premiere arrived. Kenji sat alone in the empty studio, the clock ticking toward 6:00 PM. He pressed play on the master file for Episode 1: The More Things Change: Part 1.
The screen lit up. A giant, anime-style title card exploded with neon colors: ベン10 オムニバース (Ben 10 Omniverse). The opening theme—a fast-paced J-rock anthem sung by a masked vocalist—blasted through the monitors. Then, Haru’s voice, lazy and sharp:
“Ben Tennyson. Toshi jūsan. Futsū no chūgakusei... nante uso.” (“Ben Tennyson. Age thirteen. An ordinary middle school student... yeah, right.”)
Kenji smiled. This wasn’t a dub. It was a transformation.
Across Japan, in living rooms and on phones, a new generation met a familiar hero—but for the first time, he spoke exactly like them. Not as an American cartoon character. As a Japanese one.
And somewhere in the Plumber’s base, Rook would have said: “That is a statistically significant improvement.”
