Season 3 of HBO Max and Adult Swim’s My Adventures with Superman finally concludes. And, boy, it does so with a bang! After the Eradicator (Steve Blum) appeared as a time-travel tech-oriented demigod this season, it felt like all bets were off. And that the House of El would be exterminated.
The iconic DC villain was very much subverted from the usual lore. But the show’s many tweaks made him scarier. It’s a major level up from Clark Kent (Jack Quaid) fighting the Suicide Squad and Amanda Waller’s (Debra Wilson) military in Season 1, as well as Brainiac (Michael Emerson) and an evil Kryptonian robotic fleet in Season 2. The cartoon went from grounded to ethereal, to say the least.
The dilemma progressively became worse given Kal-El was left lacking superpowers. He was last seen suffering at the hands of Brainiac back at the Fortress of Solitude, and on the verge of being killed by his Bizarro clone. Come the season finale, “The Return, as the name implies, a massive character is resurrected.
But this not-so-big-a-bombshell brings with it dire consequences. Temporary relief, ye be damned. With that in mind, here is a breakdown of how My Adventures with Superman Season 3, Episode 10 winds up an intense season.
My Adventures with Superman Redeems Brainiac Using Love
A corrupted Bizarro picks up from the last chapter — infuriated and ready to smash Brainiac’s drones apart. However, Clark protects the bots and clams Bizarro down. Think of the MCU’s Black Widow soothing Hulk’s rage.
Brainiac is stunned at this show of mercy, compassion and empathy. He realizes, per the digital test/matrix where Clark protected Brainiac 1.0 in a prehistoric simulation, Clark’s strength really is rooted in love and benevolence. Brainiac finally believes Clark is the last lord and ward of Krypton, and bends the knee. But Clark doesn’t want a loyal subject.
He wants a friend who feels liberated and who has agency. To him, Brainiac has more than just the purpose of carrying on (or forcing) Krypton’s culture. With the power of friendship curing this rift, Clark inquires as to who has been sending him visions of fire and a seeming rebirth.
Brainiac insists it’s not him, instead positing it’s the child of Rao, a god and an elemental sun. He essentially proffers that Kal must bathe and bond with the sun, although he is skeptical regarding whether the sun’s flames could kill a de-powered Clark. No risk, no reward. No guts, no glory.
My Adventures with Superman Allows Lex Luthor to Atone, Too
The Eradicator, meanwhile, is battering Clark’s allies in the field outside Metropolis. Jonathan (Darren Criss) and Lara (Jolie Hoang-Rappaport) follow the lead of their aunt, Kara (Kiana Madeira). However, the tyrant has the powers of Naruto’s Uchiha Madara.
Seriously, from his regeneration to raising clones to lightning-fast movements, he’s Madara. Anyway, he’s doing everything in his might to eradicate-duhhh. He pummels the clan, although the family teams up and kills his clone. The Eradicator quickly adapts, hijacks the Kryptonian bots Waller co-opted and sends them after Team Superman.
After Waller whisks the humans away in jets and leaves the aliens to fight, a shocking twist occurs. The plane containing Jimmy (Ishmel Sahid) and Lex (Max Mittelman) crashes. But when Slade (Chris Parnell) comes to retrieve them for Waller, he shows he has more guile than the average Deathstroke.
Lex, at Jimmy’s insistence, confesses he has a plan to stop the Eradicator. He created the being by fusing his and Superman’s DNA, after all, so he thinks his mind-control helmet can hack the goon and shut him down. Slade lets them go with a stern warning. Don’t fail or else.
It’s convenient timing. The Eradicator, floating in the sky and throwing up Naruto hand-signs, raises more clones. Only for Lex to hijack their minds and turn them against their ‘father.’ It’s very much akin to the mind-transfer jutsu from, you guessed it, Naruto.
The villain, however, hits a Reverse Uno, hacks Lex’s mind and sends the monsters after the vulnerable heroes. Thankfully, Clark arrives in a literal ray of blinding light. He smashes them in a white, regal Kryptonian armor. He admits it’s a “long story” but he’s here to save the day. Thanks, Lex!
My Adventures with Superman Levels Up the House of El
Forgiveness reigns supreme. Jonathan finally apologizes to Lois (Alice Lee) and lets her know she’s irreplaceable. He and Clark mend their fallout, too, which is weird given Jonathan was mad Clark died. As if Superman had a choice fighting the Eradicator in that timeline. Teens, right?!?!
Nonetheless, after inspirational speeches and hugs, and “cousin” Bizarro joins, they all power up and punch the Eradiclones to pieces. It’s inconsistent as to what kills the copies and just how fast the Eradicator can keep making the doppelgangers. But, you know, plot convenience.
My Adventures with Superman Kills the Eradicator
The overlord transforms into a form akin to General Zod, regenerating and whatnot. He remarks how he wins in every timeline, even if a lover, friend or child tries to help Kal. He’s fed up of all these anomalies, though. He crushes Clark’s suit and sigil. He lets Superman know he embodies the fear Lex felt and represents Lex’s need to control the world.
Admittedly, the cartoon could have upped the intimidation factor by showcasing flashbacks of the Eradicator killing the various El clans. It sets Clark up to remind him that hope always prevails. Superman punches him into oblivion, with each strike devolving the fiend.
Once the Eradicator disintegrates like he’s being ashed by the MCU’s Thanos, Clark and the troops reunite and celebrate. Lara and Jonathan disappear, wondering if their future has been saved. Clark reassures them he’ll be there to help them fight for it.
My Adventures with Superman Season 3 Ending Explained
Bizarro is seen running an ice-cream shop in the aftermath. It’s funded by Jimmy, who’s still continuing to invest in weird science projects. But these ventures show his endearing side and his corporate social responsibility.
Kara, though, puts him in something worse than the Phantom Zone: the Friend Zone. She wants to take time and be friends rather than rush a romance he craves. At least, he’ll have a thriving comics publishing business.
Elsewhere, Lex is imprisoned by Waller for his sins. He didn’t fully absolve himself after going rogue. Not in her eyes. He does let her know why he tried to create a response to Superman. He hacked a satellite and saw something terrifying in the cosmos.
It nods to Jesse Eisenberg’s Lex in a Snyderverse arc we’ll never see completed. Lex wanted to do whatever it took to feel safe. Little did he know he’d make a thug that endangered reality.
The season ends on the Kent farm. Lois adopts the dog, Krypto, Clark encountered earlier this season. The Man of Steel does duck one question, though. How did he get his powers back?
He says he made a deal with a friend his parents sent with his spaceship and the Fortress. She wants to know the cost. Flashbacks show Clark burning up and being tortured. But he’s adamant it’s nothing he wasn’t already willing to pay.
Surprisingly, Lois drops the issue. She wants to make the best of this new leash on life. She takes the concept of family a step further by proposing.
It blindsides Clark, but he says yes to her readiness to commit. It gives the season a very happy, idealistic ending.
Was My Adventures with Superman Season 3 Good?
Ultimately, the season was a bit disjointed. Using Hank Henshaw (Mittelman) as Cyborg Superman, another Lex creation, wasn’t a bad choice, as it reminded Superman how his image could be appropriated. But it wasn’t fully explained how the battle with Hank burnt out Superman’s powers. Having his tech-frame possessed by a pseudo-supernatural Eradicator would have made more sense than just having Lex chuck the Eradictor into play from inside a stasis tank in the back-half of Season 3.
The series didn’t balance Bizarro’s story well, either. It should have showed how he opened an ice-cream business in the first place, what pushed him to don Clark’s colors, and explained how humanity’s cruel ways could have opened a spot for him to have his own berserker mode. Supergirl would have been a perfect teacher here.
That said, other sub-plots were done deftly, from Supergirl becoming a mentor to Clark’s kids, to Brainiac’s redemption, to Lois realizing she has to live in the now and let her soulmate know she can’t lose him. Overall, Season 3 has enough heart, soul, romance and action for diehard DC fans or audiences looking for fresh takes. It sets the bar high and whets appetite to see how James Gunn’s Man of Tomorrow shapes up, even after Supergirl’s box-office bombing.
How My Adventures with Superman Sets Up Season 4
Firstly, we need to know the pact Kal made. It could be that, at some point, Rao may make him a conqueror or even try to possess him the way Brainiac did. At least Clark has his super-squad, the government and Waller’s Checkmate program, and Brainiac to assist if this comes to pass.
Secondly, Lex’s vision is going to be crucial. His speech is interspliced with a red and yellow palette that may be a tease for Scott Free/Mister Miracle. It could hint that Darkseid and Apokolips will invade Earth in due time. Having the war with the New Gods and allies such as Scott, Big Barda, the Forever People, and Orion’s New Genesis in play would sync up with what many DC animated series (like Young Justice) and movies aim for: galactic chaos with high-stakes.
Lastly, with the Multiverse in play and various timelines being tinkered with, the stage is set to someday hop Lois and Clark to the future. They could partner with the League of Lois Lanes once more, help their children in the future, and learn what butterfly effects cause.
Seeing all these possibilities could very well follow an Avengers: Doomsday and Secret Wars path that affirm some happy endings in timelines may be blasphemous realities that must be pruned. Choices, eh? The Legion of Super Heroes could find an entry point here, too, reiterating that messing with the temporal fabric will always yield haunting ramifications.
