Thoughts after watching Episode 20
See the original blog post here
The halfway point, Planet Balan, is a key waypoint that navigator Daisuke Shima has relied upon as a “lighthouse” throughout the voyage. In reality, however, it is a massive supply base constructed by Gamilas for their invasion of Earth, and the very place where General Domel, the “Wolf of Space” and newly-appointed Commander-in-Chief of the Galactic Campaign, sharpens his fangs to destroy Yamato.
When Yamato reaches Balan, it is met by a terrifying trap set by Domel.
“What is Yamato‘s true weakness?”
“Why is Domel’s seemingly perfect trap defeated?”
This article breaks down the highlights of Episode 20 in two parts: In-depth analysis from five perspectives and an easy-to-understand synopsis.
5 Perspectives for Understanding Episode 20
① Domel’s Insight into Yamato’s Weakness: The Trap of “Naïve Humanism”
The most chilling moment in this episode is not a battle scene, but a passage where Domel speaks to his adjutant, Gael.
“Upon seeing the form of the Balanodon, they must surely feel like saviors. Yet, there is nothing easier to exploit than that sort of simplistic humanism.”
The trap Domel sets is psychological, not based on raw firepower. He deliberately shows them the Balanodon’s carcasses and intentionally makes the base’s security appear lax. He stokes their sense of mission, provokes their righteous indignation, and channels that heightened emotion. The patience required to keep a fleet waiting in space, 500,000 kilometers away, reflects a mindset foreign to generals who rely on overwhelming firepower.
What makes it truly terrifying is that Domel’s analysis is spot-on. Susumu Kodai is indeed inflamed by the sight of the Balanodon’s carcasses and vehemently argues for attacking the base. A strong sense of justice acting as the very hand on the control stick, this is the fundamental structural weakness of Yamato that Domel exposes in this episode.
② Kodai vs. Shima: A Clash of Two Concepts of Justice, “The Vulnerable Right Before Us” or “The Lives on Earth”?
The dispute between Kodai and Shima regarding whether or not to attack the base is more than a mere strategy meeting; it is a scene where their respective concepts of “justice” collide head-on.
Kodai: “Even if they are primitive animals, I absolutely cannot turn a blind eye when I see them being slaughtered.”
Shima: “Kodai, Yamato is already running 44 days behind schedule. Unless it makes a critical difference to the big picture, we ought to head for Iscandar as soon as possible.”
Kodai’s justice is directed toward the vulnerable beings right in front of him. Shima’s justice is directed toward the billions of lives waiting back on Earth. Though their scales and timeframes differ vastly, both stem from the same fundamental desire: to save lives.
Caught between these irreconcilable forms of justice, the final decision is left to Okita, who lies confined to his sickbed. Okita sides with Kodai, but this is a strategic decision to “eliminate any cause for future concern” rather than an endorsement based on humanitarianism.
Ironically, the very sense of justice Kodai upholds is the same one Domel seeks to exploit. It is not that Kodai is wrong. However, righteousness alone is not enough to survive. This is the bitterest truth this episode confronts us with.
③ The “Rift Within Gamilas” That Saves Yamato: Gael’s Jealousy and the Dictator’s Cold Calculation
As the decisive battle begins, hidden agendas intersect in ways no one anticipates. It is neither the Wave-Motion Gun nor Shima’s piloting skills that save Yamato; it is internal conflict within the enemy ranks.
Domel’s “Artificial Sun” operation is, by his calculations, flawless. Aligning the Wave-Motion Gun’s firing axis will take 300 seconds, while the artificial sun will impact in 290 seconds. Physically, Yamato stands no chance. However, his adjutant Gael, jealous of the credit Domel stands to gain, reports to Leader Dessler that Domel intends to sacrifice the Balan Base.
Dessler: “Do you intend to sacrifice my Balan Base just to destroy a single ship like Yamato? You are an incredibly wasteful man. Desist.”
The choice of the word “wasteful” is incisive. To Dessler, the Balan Base is not a cheap asset to be traded for the destruction of just one enemy ship. There is a cold disparity in perspective between the frontline general and the supreme commander regarding “tactical victory” versus “strategic assets.” While Domel’s operation is militarily perfect, politically, it is a “waste.”
This episode reveals the fact that Gamilas is not a monolith. The brilliance of the enemy commander, the jealousy of his own ranks that hinder him, and the cold detachment of the dictator surveying it all from afar; this three-layered web of discord is what ultimately saves Yamato. Here, the structural instability within the Gamilas forces, a recurring theme in the drama to come, is decisively laid bare.
④ More than just a hot-blooded hero! Susumu Kodai’s cool-headed powers of observation, revealed through plants and wildlife
It is not the radar team or the meteorological unit that realizes the artificial sun is, in fact, artificial; it is Combat Group Leader Kodai. His deduction is based on the growth patterns of the plants and the eyes of the Balanodon creatures.
“Take a good look at this Balanodon. See? It has almost no eyes. That’s proof of a world without light.”
“Notice how the tips of the stems are all pointing downward? That’s proof they’re seeking the geothermal heat of Planet Balan.”
On a planet with light, plants grow toward it, and sighted organisms evolve. Kodai realized that this fundamental premise was being turned on its head, prompting him to question the true nature of that sun. While Kodai is often portrayed as a young man driven by emotion, here he demonstrates a cool-headed rationality, working backward from biological observations. This scene clearly captures one of the reasons why Okita chose Kodai to serve as acting captain.
Sanada’s remark, “So, the combat chief is capable of surprising sensitivity”, might sound like casual banter, but narratively, it serves as a crucial piece of foreshadowing for this episode. It is the moment the crew quietly comes to recognize that Kodai is not merely a hot-headed firebrand.
⑤ A Turning Point in the Story: The Will of the “Acting Captain” Passes from Okita to Kodai
After the battle, Okita summons Kodai to the captain’s quarters and quietly makes a request.
“Kodai, I have a favor to ask. I want you to take on the role of acting captain. My body can no longer bear the heavy burden of command.”
Okita’s body is being ravaged by space radiation sickness, and he is fully aware that his time is running out. Up until Episode 20, Okita had strictly reined in the impulsive young Kodai, standing as the embodiment of Yamato‘s reason. In this episode, however, Okita adopts Kodai’s position; Kodai’s righteous indignation toward the treatment of the Baranodons happens to align with a necessary evil required for the mission’s success.
This decision to “adopt” Kodai’s view and the subsequent “appointment as acting captain” are inextricably linked. Okita recognizes Kodai, despite his lingering immaturity, as someone capable of reinforcing his own judgment. The story’s center of gravity quietly shifts from Okita’s reason to Kodai’s passion, marking Episode 20 as a pivotal turning point.
At the midpoint of the journey, having completed one-quarter of the total voyage, Yamato‘s leadership also reaches a turning point. It is a symbolic progression.

Reaching the halfway point: Planet Balan
109 days since departing Earth, Yamato has finally arrived at Planet Balan, a point it should have passed after 65 days. Shima is anxious about the 44-day delay, but they have at least reached this “lighthouse.” From here, it is a straight shot of 71,000 light-years to Iscandar in the Large Magellanic Cloud.
Yamato‘s reconnaissance team descends Balan and witnesses something disturbing: strange vegetation attempting to burrow underground, and piles of carcasses near the shores of a lake. They belong to the combined monster Balanodon, which had previously attacked Yamato. This is evidence that Gamilas has established a base on the planet and is slaughtering the native wildlife.
Conflict over attacking the base
Kodai, having returned to the ship after restraining Kato, who tried to rush out on his own, makes a passionate plea on the bridge: “It’s our mission to destroy that base.”
Shima flatly opposes this: “We are already 44 days behind schedule. We should head for Iscandar as soon as possible.”
The decision is left to Captain Okita, who is confined to his sickbed. Okita decides to attack the base, reasoning that they must “eliminate any threat that could haunt us from behind.”
Domel’s Trap: Operation Artificial Sun Drop
In deep space, 500,000 kilometers away from Planet Balan, Domel waits silently with his fleet. While counseling an agitated Gael, telling him, “Don’t be impatient; the only thing that matters is winning the battle”, Domel is executing a strategy to drop the artificial sun hovering above Planet Balan directly onto Yamato.
By catching Yamato while its attention is focused on attacking the base, he can crush it before it can fire its Wave-Motion Gun. It is a ruthless yet flawless plan to obliterate the ship along with the base.
A desperate situation: 70 seconds remaining
As the battle between Yamato and the base intensifies, Ota of the weather team notices something amiss: “The sun is heading right for us!”
It will take a minimum of 300 seconds to ready the Wave-Motion Gun, but the collision is only 290 seconds away. It’s physically impossible to beat the clock.
Shima takes a gamble, shutting down the engines to descend via powered glide in an attempt to delay the collision, but they are still five seconds short. Despair spreads across the bridge.
“Is this the end for Yamato…?”
Domel is certain of victory. “Watch closely, Gael. This is how battles are won.”
A message from Dessler
Just then, a hyperspace transmission reaches Domel’s ship. The caller is Leader Dessler. Gael, jealous of Domel, snitched on the details of the operation.
“Do you intend to sacrifice my Balan base just to destroy a single ship like Yamato? You are an incredibly wasteful man. Stop this at once.”
The descent speed of the artificial sun slows drastically. Having narrowly escaped destruction, Yamato regroups and finally fires its Wave-Motion Gun, having aligned its aim. Struck by the blast, the artificial sun explodes violently, and countless shattered fragments rain down upon the surface of Planet Balan. The artificial sun, intended to destroy Yamato, ironically ends up obliterating Gamilas’s base with its own debris. Domel’s flawless strategy is completely turned against him at the very last instant.
Solving the Mystery and a Private Talk in the Captain’s Quarters
After the battle, Kodai explains the true nature of that sun, pointing to the Balanodon and plants collected by Yuki Mori and her team. He deduces that the creatures, eyeless Balanodons and plants that turned downward toward geothermal heat, belong to a world devoid of light, illuminated only by that “artificial sun.”
Sanada is impressed, remarking, “I’m surprised our Combat Group Leader has such a keen eye for detail.”
Later, Kodai is summoned to Captain Okita’s quarters. Okita quietly tells him, “I want you to take over as Acting Captain.” When Kodai looks bewildered, Okita simply says, “Pull yourself together.” The resolve to shoulder the fate of humanity begins to show on the young Combat Group Leader’s face.
Hurry, Yamato, toward Iscandar in the Large Magellanic Cloud. The people of Earth are waiting for your return. 253 days remain until the extinction of humanity.
