Fans of the wild science-fueled adventure in Dr. Stone have been glued to their screens since the series kicked off its final chapter. Dr. Stone: Science Future, the fourth and wrapping-up season, dropped its first batch of episodes back in January 2025, blending brainy inventions with high-stakes drama. Part 2 wrapped up just last month in September 2025, leaving everyone on the edge of their seats with cliffhangers involving sneaky alliances and moon-bound ambitions. Now, the real hype builds around Part 3—the grand finale to Senku’s quest to unravel the petrification mystery. Let’s break down the latest whispers on when it drops, who’s lending their voices, and the mind-blowing plot turns that could redefine the whole saga.
When Will Dr. Stone Season 4 Part 3 be Released?
The wait for more Dr. Stone feels endless after that intense Part 2 closer, but good news trickles in from official channels. The entire Science Future season splits into three cours, stretching across 2025 and into the next year to savor every scientific breakthrough. Part 1 aired from January to March 2025 with 12 episodes, and Part 2 ran July through September, clocking another dozen. That leaves Part 3 as the big send-off, confirmed for sometime in 2026.
No exact premiere date has surfaced yet—producers love keeping folks guessing—but patterns from past splits hint at a winter or spring launch, maybe around January or April 2026.
Voice Cast Updates: Familiar Faces and Fresh Twists in the Kingdom of Science
One of the joys of Dr. Stone lies in how the voice talents breathe life into these quirky survivors, turning stone-cold statues into vibrant personalities. The lineup for Season 4 sticks close to the tried-and-true crew, ensuring Senku’s smug grins and Taiju’s booming enthusiasm hit just right. No major shake-ups reported, but a few returning heavy-hitters and subtle tweaks keep things fresh.
On the Japanese side, Yusuke Kobayashi nails Senku’s deadpan genius once more, while Makoto Furukawa pumps energy into Taiju’s unbreakable spirit. Kengo Kawanishi handles the sly mentalist Gen Asagiri, and Riichiro Inagaki’s manga roots shine through in every line. Newer additions like Kenji Nojima as the cunning Dr. Xeno Houston Wingfield add that oily antagonist vibe—perfect for the American showdowns. Koji Yusa voices the sharpshooter Stanley Snyder, bringing gravelly menace to the mix.
English dub fans rejoice: Crunchyroll’s simuldub rolls strong with Aaron Dismuke channeling Senku’s 10-billion-percent confidence, and Ricco Fajardo as the ever-loyal Taiju. Felecia Angelle’s Kohaku swings swords and sass with equal flair, while Clifford Chapin amps up Ryusui’s eccentric billionaire charm. Sarah Wiedenheft’s pint-sized Suika steals hearts as always, and the full roster—including Justin Briner as Ginro and Kyle Phillips as Yo—returns without a hitch. A minor note from production: some voices like Dismuke and Wiedenheft juggled schedules during earlier seasons for cons, but everything synced up smoothly for Science Future.
Behind the scenes, TMS Entertainment’s Shinya Iino directs, with Yuichiro Kido scripting the clever dialogue. Music from Tatsuya Kato and crew pulses with that signature mix of triumphant rock and quirky synths—ALI’s “Casanova Posse” opener for Part 1 set the tone, and Kana-Boon’s “Supernova” rocked Part 2. No big cast news for Part 3 yet, but if manga teases hold, expect deeper dives into side characters like Xeno’s crew, possibly pulling in guest spots for emotional punches.
What to Expect Next: Plot Teases in Part 3
Dr. Stone thrives on turning “impossible” into “inevitable” through sheer smarts, and Science Future cranks that dial to eleven. Picking up from Season 3’s New World vibes, Season 4 dives into the globe-trotting hunt for petrification’s source. Part 1 and 2 covered chunks of the New America City Arc and beyond, where Senku’s squad hits North American shores, clashes with Dr. Xeno’s ragtag science empire, and forges uneasy truces amid cornfields and sniper fire. Tsukasa’s revival adds muscle and moral gray areas, while the Perseus ship’s upgrades pave the way for wilder voyages.
Part 3? Buckle up for the Stone to Space Saga’s explosive payoff. Senku’s “Moon Landing Project” takes center stage, with the Kingdom of Science racing to craft a rocket from scavenged global goodies—think nitric acid hauls from South America and alloy hunts everywhere else. Why-Man, the shadowy puppet-master behind the stone curse, lurks as the ultimate foe, pulling strings from lunar shadows. Expect laser-focused episodes on dodging Xeno’s betrayals, Suika’s helmeted heroics in zero-grav tests, and Chrome’s DIY disasters that somehow spark genius fixes.
Manga readers know the thrills: epic launches, cosmic revelations, and a finale that ties petrification’s origins to humanity’s boldest dreams. Without spoiling the juice, visualize alliances fracturing under pressure, inventions bordering on mad science (hello, orbital slingshots), and heartfelt moments where brawn meets brains. The arc blends Stone Age grit with space opera flair—sniper duels in redwood forests give way to starry showdowns. Pacing-wise, it’ll zip through battles and slow-burn for those “aha!” invention sequences, clocking in at a tight 10-12 episodes to wrap the 232-chapter manga legacy.
Visuals stay top-notch, with Boichi’s dynamic panels popping in TMS’s fluid animation—those rocket roars and stone-cracking effects will demand big screens. Soundtrack-wise, expect anthemic closers echoing the “Rolling Stone” vibe from earlier parts.
