It is important to note that while there was also an Episode 17 titled “JOKER” in Dr. STONE NEW WORLD (Season 3) which aired in November 2023, focusing on the intense conflict with Ibara and the tactical revival of Hyoga, the user’s request specifically pertains to Dr. STONE SCIENCE FUTURE. The latest iteration, Episode 17 of Dr. STONE SCIENCE FUTURE (Season 4), premiered on August 7, 2025, in Japan.
The Treacherous Journey into the Amazon
Episode 17 of Dr. STONE SCIENCE FUTURE sees Senku Ishigami’s “Youth Science Squad” pressing further into the treacherous South American continent. Their ultimate goal is to pinpoint the origin of the mysterious petrification device, the Medusa, and unravel the secrets of Why-Man. This leg of their journey involves navigating the formidable Andes Mountains and venturing deep into the dense Amazon Rainforest.
Engineering a Mountain Crossing
Faced with perilous terrain, Senku and his team demonstrate their ingenuity by constructing a makeshift ropeway. This scientific solution allows them to traverse vast chasms, highlighting the series’ consistent theme of applying scientific principles to overcome seemingly impossible obstacles. The construction and perilous crossing of this ropeway become a focal point, showcasing both the team’s resourcefulness and the ever-present danger they face from the environment and their pursuers.
Evading Stanley’s Relentless Pursuit
Throughout their arduous journey, the Kingdom of Science remains under constant threat from Stanley and his forces. Stanley’s relentless pursuit keeps the tension high, as Senku’s team must continually devise scientific stratagems to evade their technologically superior adversary. The episode emphasizes that even with Senku’s temporary advantage, Stanley is committed to a long game, adding to the ongoing suspense.
Decoding the Medusa Device
A significant subplot in “Sickening Yet Beautiful” focuses on the crucial mission to understand the petrification device itself. Senku tasks Nikki and her specialized team with analyzing the device’s intricate mechanics.
Joel’s Expertise: Unveiling the Energy Source
To aid in this complex endeavor, master watchmaker Joel is brought back into the fold. With his exceptional eye for detail and steady hands, Joel makes a pivotal discovery: he pinpoints the Medusa device’s energy source. This revelation is a critical step towards fully comprehending the device’s true power and unlocking its secrets, ultimately bringing them closer to understanding why humanity was petrified. Previous episodes had already revealed this to be a reusable diamond battery, a remarkable scientific feat in the stone world.
The Unsettling Amazonian Discoveries
As Senku’s team pushes deeper into the Amazon, they encounter new environmental challenges that test their adaptability and scientific knowledge.
Combatting Natural Threats with Science
The Amazon rainforest introduces new adversaries in the form of horrid parasites and biting insects. Ever the pragmatist, Senku quickly devises a scientific solution: an alcohol extract from army ants to create an effective insect repellent. This scene also provides a moment of characteristic humor, particularly with Luna’s reaction to the “stinky insect juice.” While these immediate threats are addressed, the narrative also hints at more severe challenges, such as water-borne parasites, reinforcing the harsh realities of their primitive environment.
The Shocking Medusa Temple Reveal
The episode culminates in a breathtaking and “sickening yet beautiful” discovery that stops the team in their tracks. After Suika finds a single Medusa device in the water, the group looks up to behold a massive, awe-inspiring temple containing millions, if not billions, of the mysterious petrification devices. This astonishing sight marks a new peak in the Science Future arc, offering a powerful reveal that promises to provide significant answers to the series’ central enigma, while simultaneously raising even more profound questions about the origins of the petrification. This pivotal moment sets the stage for the escalating stakes as Dr. STONE approaches its grand finale.
