The sequel, Princesses of Power and Robots in Disguise: The Golden Disk, was released on February 11, 2021.
There is also a sidestory series composed of one-shots.
Two worlds on opposite ends of the universe have been ravaged by war. One is gone, but the other still has a chance. When a mysterious event attracts a group of Autobots to Etheria, they become involved with the great mystery of She-Ra while the cunning Catra makes a secret alliance with the evil forces of the Decepticons.
- But for Me, It Was Tuesday: Arcee and her partner Mirage were sent to find Lockdown when he was hunting Autobot graduates and Lockdown killed Mirage right in front of her. This trope is implied when Lockdown doesn't remember Arcee until she jogs his memory of the circumstances, though he does let slip that while the bot that hired him was one of Megatron's subordinates, it wasn't Megatron himself.
- Instant Expert: Sari has the ability to be able to use a spell without much effort after seeing it in action once, which is useful because her mother Castaspella won't let her attend magic classes, so she's learning by spying on the other kids instead. She's gotten to the point where she's skilled enough to occupy Shadow Weaver's attention long enough for Adora to repair the shield spell for Mystacor.
- Let Me Get This Straight...: Sari says this word for word after Adora clues her into Adora's past and the current situation.
- My Beloved Smother: Castaspella is a little bit overprotective of Sari, initially refusing to let her learn magic despite the other kids her age at Mystacor having already started their lessons.
- My Greatest Failure: Fixit was Bumblebee's partner and blames himself for the latter's voice box getting ripped out.
- He later fails to protect Entrapta.
- Obviously Evil: Catra lampshades that she doesn't trust a group of robots with cannon arms that call themselves "Decepticons", but allies with them anyway because, unlike Shadow Weaver, she's not arrogant enough to think that the Horde can handle the Autobots without their aid.
- Only in It for the Money: Starscream doesn't trust Lockdown because he's only serves the Decepticon cause for payment, and if someone was to pay him more to betray them...
- Not So Different: Rodimus states that in training he and Arcee were a lot like Adora and Catra.
- Plausible Deniability: Shadow Weaver doesn't trust the Decepticons, and, thinking that the Horde can handle the Autobots by themselves, orders Catra and the others not to tell Hordak about them. Catra doesn't trust the Decepticons either, but knows that they need an edge against the Autobots, so she gives them a communicator so she can keep in contact with them. Knowing that Adora will probably have Autobots with her during future encounters, her plan is to pass information on Adora's whereabouts to the Decepticons, so the they can show up to fight said Autobots, with no revealing that they made contact. That way, they'll gain enough attention in the Horde that Shadow Weaver won't be able to keep them under wraps, allowing Catra to get them to Hordak's attention without getting in trouble. Knock Out is impressed by her craftiness.
- Production Throwback: In addition to imagining the She-Ra cast as in the same outfits as their 80s versions, the Cybertronians are reduced to their blocky G1 designs as well. When Arcee questions this, Bow reveals it's because he couldn't get their figures stable unless they were blocky.
- Related in the Adaptation: Sari is Castaspella's daughter, and thus Glimmer's cousin, in this universe.
- Shout-Out: Sari's line to Shadow Weaver is a slightly modified version of what Luz says in the first episode of The Owl House right before firing her firework at Warden Wrath.
- Time Skip: The sequel starts place three weeks after the previous story ended.
- Ultimate Universe: The Transformers part of the crossover cherry-picks characters and plot elements from several continuities, like Sari from Animated and Knock Out from Prime, the Predacon Waspinator, etc.
- Villain Team-Up: Catra makes an alliance with Starscream and his Decepticon forces against Adora, the Princess Alliance, and the Autobots. Interestingly, it's initially just with Catra, and those Horde forces aligned with her, since Shadow Weaver is trying to keep Hordak out of the loop about the Cybertronians.
- The Voiceless: Bumblebee speaks in beeps and buzzes like in Prime, the bots and later Bow can understand him just fine.
- You Are Better Than You Think You Are: Sari tells Adora this when Shadow Weaver plays her mind games in Mystacor.
