In the gripping 20th episode of Dr. STONE SCIENCE FUTURE, the highly anticipated fourth season of the acclaimed anime, the Kingdom of Science faces its most dire challenge yet as the final confrontation with Stanley and his formidable forces erupts. Airing on August 28, 2025, this episode plunges viewers into a brutal battle where scientific ingenuity clashes with overwhelming military might, pushing Senku’s allies to their absolute limits and beyond.
The Eve of Battle: Fortifying the Medusa Stronghold
As the threat of Stanley’s advanced military unit looms, Senku and his dedicated team are shown desperately working to fortify their base around the Medusa device. This ancient petrification device remains their ultimate, albeit risky, trump card in the escalating war to save humanity. Their hope hinges on reactivating the Medusa, a move that could turn the tide against an enemy equipped with modern weaponry.
Stanley’s Landing and a Perilous Warning
The episode opens with Stanley’s forces making their decisive landing in Arasha, signaling the start of the full-scale assault. Recognizing the immediate danger, Suika and François bravely attempt to alert Senku to the enemy’s presence. However, their efforts quickly lead them into a critical situation, culminating in their capture by Stanley’s soldiers. Despite being taken hostage, François manages a crucial act of defiance, sending a vital warning to Senku via Morse code. This desperate message underscores the urgency of their predicament and the rapid advance of their technologically superior foe.
The Desperate Guerrilla Assault
Upon receiving the alarming news, a trio of the Kingdom of Science’s most formidable fighters—Kohaku, Tsukasa Shishiō, and Hyoga—launch a daring and desperate guerrilla assault. Their objective is to stall Stanley’s unit, buying precious time for Senku to enact his larger plans. This confrontation is marked by intense and surprisingly brutal combat, highlighting the stark reality that even elite warriors are severely outmatched against organized soldiers armed with semi-automatic firearms.
Sacrifices on the Battlefield
The clash takes a grim turn as the combined might of Kohaku, Tsukasa, and Hyoga, despite their incredible individual prowess, proves insufficient against Stanley’s well-equipped and trained forces. The episode depicts these key characters enduring significant, seemingly fatal, injuries. This dramatic shift in tone, from the often light-hearted scientific endeavors, injects a profound sense of despair and high stakes into the narrative, with discussions arising about the potential for their revival through the Medusa’s restorative properties.
Acts of Humanity Amidst Conflict
Even in the heart of this brutal conflict, moments of unexpected humanity shine through. When an enemy combatant named Charlotte is bitten by a poisonous spider, the compassionate Suika, despite being a hostage, selflessly intervenes to help. She utilizes a primitive form of the vasodilator Glyceryl Trinitrate, a testament to the scientific knowledge cultivated by Senku’s group, to prevent Charlotte’s imminent death.
Furthermore, Ginro, initially prone to fear, demonstrates remarkable courage. Despite being bound, he manages to free himself and expertly disarms multiple soldiers with a spear before being overpowered, showcasing his growth and determination in the face of overwhelming odds.
The Science of Survival: Medusa as a Final Hope
With his strongest fighters seemingly neutralized, Senku’s strategic mind is in overdrive, contemplating the next steps to utilize the Medusa device. The episode emphasizes that while his allies made immense sacrifices, their potential salvation might still lie within the very science that defines their struggle. The looming question remains whether Senku can activate the Medusa in time to reverse the damage and turn the tide of this climactic war.
Dr. STONE SCIENCE FUTURE Episode 20 delivers a powerful and emotionally charged installment, marking a significant turning point in the final arc of the series. It showcases the brutal realities of war while reaffirming the enduring power of science and human spirit, even when facing seemingly insurmountable odds.
