Fans of that wild mix of brains and brawn in a stone-cold world can’t get enough of Dr. Stone. The series wraps up its epic run with Season 4, subtitled Science Futureand after two solid chunks of episodes, eyes are glued on Part 3. This final stretch promises to crank up the science showdowns and globe-trotting drama. Let’s break down the latest whispers on when it drops, who’s lending their voices, and what wild turns the story might take—without spoiling the fun for newcomers.
When Will Dr. Stone Season 4 Part 3 Hit the Screens?
Excitement’s building for the last leg of Dr. Stone‘s grand finale. Part 1 kicked off strong back in January 2025, rolling out 12 episodes through March that dove deep into the New America City chaos. Then Part 2 heated things up from July to September 2025, with 10 more episodes wrapping the South America skirmishes and teasing bigger mysteries. That left folks hanging on a cliffhanger that screamed “more soon.”
Good news rolled in during the fall: Crunchyroll confirmed Part 3 lands sometime in 2026. No exact date yet—could be spring (April-June) or fall (October-December), based on the show’s split-cour rhythm. A fresh teaser visual dropped in December 2025, showing Senku eyeing the moon with that signature smirk, hinting at cosmic stakes ahead. Over on X, anime hubs are buzzing about it, with one post sharing the key art and counting down to the 2026 premiere. Patience pays off here; the three-part split lets creators polish every gadget and gadgeteer just right.
Voice Cast: Returning Heroes and New Faces Steal the Spotlight
Dr. Stone shines thanks to its killer voice lineup, blending sharp smarts with raw power. The core crew’s back for Part 3, keeping that Kingdom of Science vibe alive. In Japanese, Yusuke Kobayashi nails Senku’s cool-headed genius, while Makoto Furukawa brings Taiju’s endless energy. Kengo Kawanishi handles the brooding Tsukasa, and Ai Kayano voices the fierce Kohaku—timeless picks that make every line pop.
English dub fans got the green light for simuldubs starting January 2025, so Part 3 should follow suit on Crunchyroll. Aaron Dismuke owns Senku’s 10-billion-percent swagger, Ricco Fajardo pumps life into Taiju, and Felecia Angelle’s Kohaku cuts like a lion’s claw. Sarah Wiedenheft’s take on little Suika tugs heartstrings every time, and Clifford Chapin’s Ryusui oozes that pirate flair.
But here’s the fresh twist: Season 4 sprinkled in new talent to amp up the global feel. Kenji Nojima steps in as the cunning Dr. Xeno, a rival brainiac clashing with Senku’s crew. Koji Yusa growls as the sniper Stanley Snyder, adding gritty menace. Megumi Han joins as Chelsea, the whip-smart geographer who’s all about maps and mayhem, and Reigo Yamaguchi voices Leonard, the radar whiz from the old U.S. military days. More additions like Mariko Higashiuchi as Maya and Akira Sekine as Luna popped up in early 2025 announcements, rounding out the international squad. These voices don’t just fill roles—they crank the tension, making every alliance and betrayal hit harder.
Plot Teasers: What Wild Science Awaits in the New Stone World?
Dr. Stone thrives on turning rocks into rockets, and Part 3 dives into the New Stone World arc, picking up right after that heart-pounding Part 2 finale. Without diving into major spoilers, expect the Kingdom of Science to grapple with a world flipped upside down—think fresh petrification waves and solo survival stunts that test even Senku’s unbreakable logic. Suika steps up big time, channeling that pint-sized determination into game-changing discoveries, while the gang revives old allies and forges uneasy pacts.
The real hook? Senku’s moonshot plan ramps up, chasing the elusive Why-Man and unraveling petrification’s secrets. Globetrotting crews split off to rebuild cities, tweak rocket tech, and dodge snipers in exotic spots—from foggy islands to ancient ruins. Battles blend brains over brawn: dogfights in the sky, clever revivals that flip the script on enemies, and inventions that make immortality feel scarily real. It’s not just about surviving the Stone World anymore—it’s about rewriting humanity’s future, one equation at a time.
