Anime: Blue Submarine No. 6

aka: Blue Submarine Number Six

"A sea of endless blue..."

A four-episode anime, taking place after the apocalypic flooding of Earth by Emperor Scientist Dr. Zorndyke. With the remaining cities ravaged by Zorndyke's army of fish-human hybrids - his "children" and intended heirs to the new world - the last hopes of humanity fall on the remaining submarine fleet, the titular No.6, and cadet-turned-slacker Tetsu Hayami.

Aired on Toonami back in its glory days. After Bandai Entertainment completely ceased DVD production, the rights are now in the hands of Discotek Media, who have so far rereleased the series on DVD and Blu-Ray.


  • After the End: All coastal human cities are underwater as a result of Zorndyke's arctic melting.
  • Anti-Hero: Kino.
  • Anti-Villain: Zorndyke, depending on whether you sympathize with his motivations.
  • Apocalypse How: A Class 1. Zorndyke flooded earth's coastal areas. And he is planning to turn it into a Class 4.
  • Big Sister Instinct: Kino is hinted to be this towards Huang.
  • Bittersweet Ending
  • Child Prodigy: Huang Mei-Ling is ten years old and operates complex sonar machinery for a military vessel.
  • Clueless Aesop: something about a cycle of revenge when the enemy really is Always Chaotic Evil (good or at least nice members are killed), are killing the remains of humanity and enjoying it greatly
  • Conspicuous CG: Gonzo were never known for their ability to believably incorporate CG into their animated series. Blue Sub 6 is among their earliest efforts, so one might forgive them in this case - particularly as the rest of the animation is gorgeous.
  • Cool Ship: Blue Sub No. 6, and many others.
  • Cute Monster Girl: Mutio and the other fish-girls, as well as the furry girl at the end.
  • Cute Mute: Mutio, just about. The only word she can say is Hayami.
  • Emperor Scientist: Dr. Zorndyke is the poster boy for this trope.
  • The End of the World as We Know It: What sets of the main plot of the series, is Zorndyke plan to reverse the magnetic poles of the earth, thus rendering it completely uninhabitable.
  • Expy: Zorndyke is Dr. Moreau, more or less. See below.
  • Fanservice: Hayami's shirtless scene at his introduction and in the third episode, plus Kino's skin-tight body suit, which she often unzips halfway for some cleavage. Mutio speaks for herself...
  • Fish People
  • A God Am I: Subverted. Zorndyke doesn't think of himself as one because he thinks he is "not nearly so arrogant as that".
  • Heroic Sacrifice: The Japanese SSGN that attacks the Ghost Ship.
  • Hidden Elf Village: There is a village of hybrids hidden behind the mist where the North Pole formerly stood.
  • Hot Sub on Whale Action: Most of the fight scenes.
  • Hopeless War
  • Hypocrite: Zorndyke believes Humans are the real monsters and would screw everything up. He was the bastard that screwed everything up and refuses to own up and instead continues on like some Nietzsche Wannabe
  • Inter Species Romance: Hayami and Mutio. Enforced or at least friendship for humanity and Zorndyke's creations even though most of Zorndyke's creations are evil/do nothing in the war.
  • Literal Change of Heart: Turns out that Dr. Zorndyke removed his own heart and used it to power the Earth's destabilizing magnetic field.
  • Macross Torpedo Massacre
  • Mad Scientist: How the world (and a fair number of viewers) view Zorndyke.
  • Mermaid Problem: Averted. Implicitly.
  • Mickey Mousing: Hot Sub-on-Sub Action choreographed to bossanova. It's as awesome as it sounds.
  • Misanthrope Supreme: Why Zorndyke created his fish-people and flooded the world in the first place.
  • Nice Job Breaking It, Hero: See below. No. 6, unintentionally, leads Verg and the Ghost Ship right to the secret base of Blue Fleet.
  • No-Holds-Barred Beatdown: Verg to Hayami at the end.
    • Not to mention the severe (though short) beatdown Mutio receives at the beginning of episode 4 (and just before the start of the episode) with a sheathed, heavy sword. Leaving her just enough strength to limp-swim away, bloody and injured.
  • Nuke 'em: Humanity's back up plan to finish Zorndyke.
    • "So that's the plan? Nuke the psycho? That's original." -Hayami
  • Ocean Punk
  • Our Mermaids Are Different: Mutio and her sisters.
  • Perfect Pacifist People: show up towards the end. Rule of Symbolism makes the place where they live seem like heaven. Did we mention they've found by the protagonist at the end of a war?
  • Psychopathic Manchild: Verg. He wants to please Zorndyke, whom he calls "Papa", but is extremely violent and prone to throwing temper tantrums.
  • Recycled UNDER WATER!: The series is essentially a retelling of The Island of Doctor Moreau WITH FISH PEOPLE.
  • Self-Fulfilling Prophecy: Zorndyke believed humans are the real monsters and would ruin everything. Naturally he ruined everything.
  • Scary Shiny Glasses: Zorndyke
  • Scavenger World: As a result of many of the former cities being underwater now.
  • Sci-Fi Writers Have No Sense of Scale: While 1 billion people seems like a lot, given the effects of the flood (enough to half-way sink a skyscraper) it should've killed a lot more. To get an idea: there are about 7 billion people currently in the world.
    • However the flooding due to polar ice melt would not have occurred instantaneously and it is likely that mass evacuation inland occurred. Indeed the vast bulk of the deaths are most likely due to subsequent starvation and disease as the inland areas would have been ill-equipped to support such a massive refugee population, and to attacks by Zorndyke's forces. Musuca 17 / Red Spot for instance relates that his species were tasked to "wander the seven seas, destroying human cities".
    • The English dub over-corrects and claims 10 billion people died.
      • Though they did mention that humanity basically solved World Hunger some time before the war started, so that could explain a population boom.
  • Silence, You Fool!: Verg in the dub.
  • Soundtrack Dissonance: It's debatable whether the rather discordant, wailing jazz soundtrack fits the tone of the series.
  • Star-Crossed Lovers: Though at least it's implied by the final episode credits that Hayami and Mutio will eventually get back together once things finally settle down.
  • Sunken City: One early episode even featuers Hot Sub-on-Sub Action within the cramped man-made canyons of the submerged skyscrapers.
  • Transforming Mecha: The Grampus mini-sub.
  • Tsundere: Hayami. Mostly tsun.
  • Underwater Base: The headquarters of the Blue fleet. It is destroyed minutes after it is introduced, by Verg, who followed No. 6.
  • Underwater Ruins: See above. We see mostly Tokyo, but is implied that most of the world is flooded.
  • "Well Done, Son!" Guy: Verg.
  • Well-Intentioned Extremist: Zorndyke.
