Side-by-Side Comparisons
“The Greatest Robot on Earth” and Pluto
The best place to start in comparing these series is their summaries. This summary for “The Greatest Robot on Earth” comes from the 2002 Dark Horse release:
“In the novel-length "The Greatest Robot on Earth," a wealthy sultan creates a giant robot to become the ruler of all other robots on Earth. But in order for that to happen, he must defeat the seven most powerful robots in the world, including Astro Boy, who must have his horsepower raised from 100,000 to 1,000,000 to face the challenge! And his sister, Uran, also flies in to lend a helping hand!”
Well, besides the fact that Uran doesn’t actually fly, I suppose that’s true enough. Gotta love marketing copy.
And here is Viz’s summary for Pluto: Urasawa X Tezuka, vol. 1:
“In an ideal world where man and robots coexist, someone or something has destroyed the powerful Swiss robot Mont Blanc. Elsewhere a key figure in a robot rights group is murdered. The two incidents appear to be unrelated...except for one very conspicuous clue - the bodies of both victims have been fashioned into some sort of bizarre collage complete with makeshift horns placed by the victims' heads. Interpol assigns robot detective Gesicht to this most strange and complex case - and he eventually discovers that he too, as one of the seven great robots of the world, is one of the targets.”
An ideal world, eh? Well, I’m all about subverting surface appearances, so I like it. Anyway, right off the bat, we can tell that these two series aren’t the same genre, aren’t using the same principal characters, and aren’t concerned with the same stakes. They seem to only have one thing in common: the word “robot”.
The following pages for “The Greatest Robot on Earth” are from the Dark Horse Omnibus. In most cases, I have used pages from Viz’s Pluto: UrasawaXTezuka, but there are a few pages from the fan scans. Why? Because I own the physical manga, didn’t want to pay for all the volumes again in a digital version, and realized that the images in the fan scans were cleaner and bigger than most of the ones I could get from cracking the spine of my books and mooshing them on the scanner.
Pluto at Its Most Faithful
Mont Blanc died first in “The Greatest Robot on Earth”, and in Pluto he fares no differently. Of course, in true dramatic Urasawa fashion, Pluto chooses to begin with the fiery discovery of Mont Blanc’s head tucked within his killer’s calling card to establish the mystery and suspense of this work rather than start with a quaint lumberjacking-scene-turned-robot-fight like the original.
Urasawa and Nagasaki’s choice to include human victims in Pluto also immediately raises the stakes in a way that “The Greatest Robot on Earth” never did or would. It also immediately changes the type of exploration within the world that the series would do, given that the robots of the extended Astro Boy universe are believed to follow Asimov’s Laws.
Greece’s Hercules, spelled Heracles in Pluto’s English translation, is a straightforward warrior-type in “The Greatest Robot on Earth”, and he sasses the crap out of Epsilon when he shows up to speak with him just as he does in Pluto. He then gets trounced by Pluto after a drawn-out fight.
In Pluto, Hercules still fits the original warrior archetype, but with the addition of his very own character arc! His rivalry and friendship with Brando is new and refreshing, and his blooming respect for Epsilon pairs nicely with his own discovery of his humanity and personal beliefs as it relates to combat, war, and victory.
They called him the god of victory, after all, not necessarily bloodshed. He may have lost his fight with Pluto, but he went down believing he won and with a newfound appreciation for life and the bravery it requires to not fight. His manager Al Haft(a) is an easter egg character.
In real life, Greece participated in the Gulf War, but disagreed with the 2003 Iraq War and did not participate. Meanwhile, Australia participated with the goal of growing closer to the USA. In Pluto, these stances were swapped in their representative robots.
Personally, I think Epsilon (sometimes called Photar in the Astro Boy anime adaptation dubs) is the most surprising figure in these page comparisons if only because he didn’t actually change that much between works. Instead, it is Wassily who exploded onto the Pluto scene with his very own expanded story and Bora trauma. Yes, the disembodied hands scene is in both.
Pluto’s Epsilon looks just like Monster’s Johan, which is funny—Urasawa seems to use Tezuka’s Star System method across his works. In English, Johan and Epsilon are voiced by the same guy, too.
Speaking of, Bora is native to “The Greatest Robot on Earth”, and he is still a bomb. In “The Greatest Robot on Earth”, his creator takes the time to tell the sultan that he created him just to beat Pluto and, by extension, the sultan. In Pluto, Bora’s existence and purpose is to exact vengeance on a broader scale.
Uran’s changes between series are actually really straightforward. In the postscript of the physical Pluto manga’s volume 6, essayist and critic Gorot Yamada laments the fact that Urasawa avoided the “ero-kawaii” of Uran confronting Pluto in nothing but Atom’s briefs and calls it a “minor weakness” since it is representative of Urasawa’s relatively gentler hand in showing “cruelty or eroticism” when compared to Tezuka.
I can’t begin to tell you how funny I think this criticism is, although I do believe that Urasawa does have, overall, gentler sensibilities than Tezuka. But still. I don’t think we’re missing much by keeping Uran in her clothes. She’s still a snot, she’s still a braggart, she’s still good-hearted, and she still makes her big brother look like a square and a stick-in-the-mud. Writing precocious little girls and sweet stories of unlikely bonding moments are a few of Urasawa’s specialties, so I don’t find it surprising that he took the Uran by the hair-horns and maximized her existing character traits.
Spiritually, she feels consistent to me, though her basic actions are decidedly different: Pluto’s Uran doesn’t fight or try to fight Pluto, doesn’t want Atom to fight Pluto at any point, doesn’t ever hate Pluto, and has empathy-based powers (separate from that, she may just be smarter and more emotionally intelligent than the original Uran).
However, the sequences in the park and the underpasses where she befriends Pluto strongly resemble Uran’s near-naked adventures in the streets of “The Greatest Robot on Earth”, and that’s fun.
Abullah is where things get spicy, and that’s mostly because the only real change to his character was the addition of his human backstory and discovery of hatred. In Pluto, he is Tenma and Abullah’s science project who believes he is a human scientist (which he isn’t), but he’s actually also got a split personality! That’s a lot. There’s just so much going on with that. But still, where Pluto’s twist falls on the scale of wild twist bullshittery lessens considerably once you know how this character is portrayed in the original, I feel.
In “The Greatest Robot on Earth”, Abullah is a robot butler disguised as a scientist disguised as another scientist. Not to pooh-pooh the original’s Scooby-Doo antics, but, by comparison, Pluto’s reveal is actually quite nice, logical, and thematically consistent. It also gives Tenma a chance to look cool and not just pathetic.
Professor Ochanomizu is the best character. Don’t argue with me. In Astro Boy, he has a big heart and a big temper to match, and he gets knocked around more than Wile E. Coyote in a Looney Tunes segment. He spends most of “The Greatest Robot on Earth” being kidnapped and hanging out with the sultan, but Pluto spreads the wealth by letting the other roboticists be the damsel in distress throughout the plot.
In Pluto, he’s mostly characterized by doing kindly old man shit (do you recognize that robot dog and how it definitely influenced Ochanomizu’s design for Bobby?), but it is absolutely the kind of stuff the original Hiroshi Ochanomizu would do. He gets treated with more on-screen respect in Pluto than in Astro Boy, but only because he isn’t as cartoony. The animation team made damn sure to have the physics of his stomach work not like those of an innocent-at-heart anime girl’s titties when he’s enthusiastically running to the next big important thing, and that’s exactly the right spirit for a creator to have towards this character. A+ job, M2.
Also, in the manga only, Ochanomizu is the facilitator for the single most entertaining referential gag in all of Urasawa’s works: the police dog car diagram. This was cut in the anime.
In the postscript of Pluto: UrasawaXTezuka volume 5, manga critic and lecturer Tomohiko Murakami observes that “Urasawa’s depictions of Professor Tenma and Professor Ochanomizu almost appear to be [his] perspective on two different aspects of Osamu Tezuka’s character.” I don’t necessarily disagree, especially given the commentary Tezuka gave regarding Atom’s status as a “monster”, but I think that Ochanomizu and Tenma also more generally represent the “dark” and “light” side of progress and science. This is likely what Tezuka intended for them, too, back when he was writing the series.
But Tenma is just a hot mess. For the duration of “The Greatest Robot on Earth”, he was more or less emotionally stable up until the “death” of Atom (and guess what? He totally enabled Atom’s increase in strength to 1,000,000, despite Ochanomizu constantly advising Atom not to do), though his general moodiness and instability is a defining character trait for much of the series. He gets better over time, but make no mistake: he is an eccentric, reclusive, and vain disaster man.
In Pluto, Urasawa lets Tenma’s disaster qualities shine alongside his signature ego, moodiness, cynicism, and destructive tendencies. This man self-sabotages like it’s his job. He also flings his creations around willy-nilly and never thinks about the consequences, and that’s why he has a hand in a significant number of the most harmful and destructive events in the extended Astro Boy universe somehow, including in Pluto.
Tenma’s rejection of Atom at the dinner table in Pluto is way classier than his breakdowns in the original Astro Boy manga, but I liked the gravitas of the scene and the over-the-top vibe of the fancy dinner in the sunset. Tenma’s portrayals throughout different series run the gamut from “frenetic cartoon maniac” to “vanilla un-stellar dad” to “Phantom of the Opera”, and this is a nice lean towards the latter end of the scale.
His constant contest over ownership of Atom/influence over Atom with the Ministry of Science (and specifically one Hiroshi Ochanomizu) extends beyond “The Greatest Robot on Earth”, though, and I think elements of their more direct conflicts are very present throughout Pluto. I love an old man fight, and it seems Urasawa does, too.
But goddamn is it satisfying to see Ochanomizu tell Tenma to shove it where the sun don’t shine.
Apparently, their dynamic is so popular that it inspired a completely new series set in the alternate universe where they not only go to college together, but are best friends. If you want something fluffier than Pluto where the old men aren’t old, go read Atom: The Beginning, I guess.
And, like, sure. This is all great. But sans the extended old man drama, many of these side-by-sides have been pretty faithful to “The Greatest Robot on Earth”, and that is NOT what Makoto Tezka asked for.
Pluto as a Remix of Astro Boy
North No. 2, called Monar in “The Greatest Robot on Earth”, is generally the same robot as in his original portrayal, but instead of just going to fight Pluto, he stars alongside new character Paul Duncan in a brand new story about pianos and music and being blind and growing past trauma to accept others into the heart. Tezuka’s Kuroo Hazama (Black Jack) was even there in Paul Duncan’s memories. It had everything: crying old people and kids, medical drama, orphan trauma, mama trauma, prostitution implications, castles, the emptiness of fame and fortune, singing, an android dreaming of more than just electric sheep, long monologues, and an emotional goodbye where one character stares longingly (even if he can’t actually see anything) at the other knowing they shall never return.
I’ll just say it: Turkey’s Brando is a total red shirt in “The Greatest Robot on Earth”. Meanwhile, Urasawa gave him a family, a love of Turkish drinking culture, a friendship and rivalry with Hercules, and a penchant to dabble in illogical forces like luck, and a classic tearjerker death. Urasawa gave him the world.
In the anime, Brando is among my favorites. Y’all can swoon over your twink Epsilon or whatever, but it’s Brando over randos for me!
Chochi Chochi Ababa transformed into Saddam Hussein—er, Pluto’s King Darius XIV. One is a cartoon villain who provides an opportunity to learn a basic moral lesson, and the other is a motherfucking war criminal. I think that's a sufficiently mature new twist on an old concept.
Of all the characters present in Pluto, Atom himself is likely the one that gave Urasawa and Nagasaki the most grief, if only because he is the one and only Astro Boy, hero of justice, and if his portrayal wasn’t popular, they’d probably be sent to manga hell forever.
For me personally, one of the most gratifying details regarding his portrayal is how quickly he will lie while maintaining the lie that robots can’t and don’t lie. This line of thinking, as well as the implication that Atom follows Asimov’s Laws more because he wants to, not because he has to follow his programming, is something that became more and more apparent the longer the original Astro Boy ran even if none of the other characters directly said anything about it. Speaking as a fan, I also think it’s nice that Urasawa makes the most of upholding Atom’s observed personality traits throughout adaptations. That he made Atom a deeply curative flavor of an insect kid is a grounded, but nice touch.
(It may also be worth noting that Osamu Tezuka had a known fascination with insects. The “Mushi” in Mushi Productions means “insect”. I don’t know how intentional that was, but it seems Pluto’s Atom may have been intended as a chip off the ol’ Tezuka block whether he was his “monster” or not.)
But as lovely and detailed as Urasawa’s embellishments on these characters is, this is still not what Makoto Tezka asked of him. So far, these characters are strikingly similar to the existing “The Greatest Robot on Earth”, and apparently, if Tezka’s interview in the postscript of Pluto: UrasawaXTezuka volume 2 is to be believed, he told Urasawa multiple times to keep revising until he made it his own! It seems Atom really became Urasawa’s monster, too!
