First, an introduction: Thundercats was one of the glorious toy-commercial cartoon shows of my childhood in the 1980s. It hit that perfect delightful blend of sci-fi and fantasy, violence (but not too much for 1980s moral guardians) and philosophy (“life lessons” enough to satisfy 1980s moral guardians), and over-the-top hammy acting. The animation was shockingly good for the era, as it was being produced in Japan at a higher standard of quality than most kids action cartoons that reached the US at the time.
The original Thundercats cartoon series debuted in 1985. Starting in December of 1985, Marvel Comics, through their Star Comics imprint, published the first issue of ThunderCats. Publication was bimonthly for the first 8 issues, and then switched to a monthly publication schedule for the remainder of the series, ending in June of 1988. I have a few of the original issues from that series in my collection, but recently backed a crowdfunded re-published collection of the entire series.
I read issue #1, and was like, “Wait, this doesn’t seem to line up with what I remember exactly,” but it had been years since I rewatched any of the original cartoon episodes. So I went back and watched the first four episodes--the first four episodes were originally aired together (as were the first five episodes of the second season, if I remember correctly, as they make a single complete narrative), though officially only the first two are the pilot. To be fair, if I was actually trying to be true to my original experience, I’d need to watch those four episodes half a dozen times each via grainy VHS, while fast-forwarding through 80s commercials and rewinding each time. But so we’re all on the same page, I’m going to start my review/recap of the comic books with a review/recap of the first few episodes of the cartoon, to put us in the mindset of a seven-year-old picking up the comics for the first time.
Leonard Starr was the series’ head writer and was credited with writing the first four episodes. Should I go look up interviews with him? Probably! But whatever! Onwards!
The first episode is titled “Exodus.” The cartoon opens with the ‘Cats escaping the ruins of Thundera and each establishing their characters in a few lines, then watching Thundera explode on the viewscreen. Jaga shows Lion-O the Sword of Omens and drops some exposition about it, as well—and Lion-O can’t even lift it yet. Then he gives the Thundercats their clothes and weapons, and the ship is attacked by mutants from Plun-Darr, who have formed an alliance against them. The rest of the Thunderian ships are destroyed so that the mutants can board and try to take the Eye of Thundera. The ‘Cats fight with the mutants; and Slithe finds Lion-O with the sword, but he successfully channels its power to drive them off. The ship has been damaged, and they need to go to a different galaxy than they’d expected, so they change course to Third Earth and need to use the suspension capsules to get there. Jaga volunteers to stay awake and pilot there. “Even though the suspension capsules slow down the aging process, some aging does take place;” and he’s already so old he’d die on the way anyway. Some amount of time passes, and shortly before they arrive, Jaga activates something on his wrist and turns to dust. The robot pilot successfully crash-lands them on Third Earth.
Snarf wakes Lion-O, who hit puberty in the suspension capsule and is now all grown up. Then a mutant ship arrives minutes later, to search the wreckage for the Eye of Thundera. Lion-O is foggy-headed but attacks the mutants barehanded; Jaga’s spirit appears and reminds him how the sword works, so he uses it to wake the other ‘Cats and drive off the mutants. The Thundercats scavenge the remains of the crash to set up their new home.
The second episode is “The Unholy Alliance” and follows right from where we left off. We jump back to the mutants who are looking for where the Thundercats are setting up and happen upon Mumm-Ra’s pyramid. (They note they’re also looking for a spot to build their own Castle Plun-darr.) Mumm-Ra forces them to crash at the pyramid.
We briefly return to the Thundercats as Lion-O decides to go out checking the perimeter and Snarf whines. Tigra gives the length of their journey in suspension: 10 glacto-years. He also reminds us that Lion-O got bigger but hasn’t actually grown up.
Mumm-Ra welcomes in the mutants and introduces himself. Mumm-Ra has known about the Eye of Thundera for 1,000 years, “since this was still First Earth.” Mumm-Ra sinks the mutant ship and strands them on Third Earth and at his mercy so they’ll work for him in trying to steal the Eye together. He shows them that Lion-O is alone and teleports them to ambush him. Lion-O tries to hunt some deer, and the sword embeds itself in the ground until Jaga teaches Lion-O that the Sword can’t be used frivolously, only to combat evil. The mutants appear and attack, and Lion-O is joined by Panthro and the kittens and they drive off the mutants.
Back at the pyramid, Mumm-Ra shows off his ability to transform and flies off to menace the Thundercats with what he can do.
Lion-O happens upon a tar pit and is attacked by Mumm-Ra, who he decides to try fighting alone. When he when tries to summon the Thundercats, the sword is covered in tar and the Eye won’t open. All seems lost until Mumm-Ra sees his reflection in the Claw Shield and is driven away.
Episode 3, “Berbils”. We pick up again with Lion-O and Snarf exploring more. Snarf shows off some actual bravery on the wildlife and Lion-O falls in a pit. He gets rescued and captured by some Ro-Bear Berbils.
Meanwhile, Panthro has finished building a Thundertank, just in time for a rock-rainfall to begin. The rockfall buries the ship with most of the team inside, but Panthro and the Thundertank pull them out. (The origin of the rockfall is never revealed, though it’s vaguely implied Mumm-Ra had a hand in it.)
The Berbils quickly reveal themselves to be friendly and willing to share food, so Mumm-Ra transforms into a swarm of insects to attack them. Then he turns into a giant insect, the better for Lion-O to wrestle with—and dumps Lion-O in a volcano. Jaga teaches Lion-O to summon the sword to his hand and he uses it to fly out of a volcano…and Mumm-Ra just gives up, I guess? Anyway, the Berbils come meet the rest of the Thundercats and volunteer to help build the Cat’s Lair.
Episode 4 is “The Slaves of Castle Plun-darr” and the last episode of the premiere. It opens with the kittens discovering that the mutants have enslaved local “brutemen” and constructed Castle Plun-Darr. Monkian catches them, but they give him the slip. Tigra and Cheetara are overseeing the completion of Car’s Lair. (They note that Tigra created the plans for Cat’s Lair—they clearly tried to establish Tigra as the scholar and Panthro as the engineer.) The Thundercats take the Thundertank to go deal with the mutants. (Did you want a toy commercial for the Thundertank? Because that’s what’s going on for two solid minutes here.) There’s clearly a parallel between the two lairs being constructed, and the contrast of the Thundercats accepting help from the friendly Berbils and the mutants enslaving the brutemen.
Through all of these episodes, the mutants are consistently incompetent and the Thundercats easily best them in direct combat. Slithe tries to turn the tide by using warp gas to make the brutemen angry and violent, because the Thundercats won’t want to hurt them. Unfortunately, the gas wears off too fast. Warp gas is illegal by galactic treaty, but “Rules are only meaningful if people agree to follow them, otherwise they’re just words.” When Slithe throws another gas bomb, Lion-O creates a force field with the sword and drives the gas (and the brutemen) towards the mutants, who flee. Then the gas wears off again and the brutemen are convinced of their freedom, so they leave.
That’s actually a pretty solid intro to the series! We’ve got a lot of worldbuilding and character setup, we understand the threats (the mutants, Mumm-Ra) and what they want (the Eye of Thundera), and we have the first few weird features of Third Earth setting the stage for lots of further exploration. We have a “kid in adult body” self-insert character for the viewers and a cool supporting cast including The Smart Guy, The Hot Chick, The Strong Bald Dude, the two Mischievous Kids, and the Comic Relief Mascot. It’s not at all surprising they got 140 episodes out of this!
