It aired on NickToons, 9:30 am, on Saturday morning on September 15, 2018.
The Mysticons, Proxima and their allies face-off against the Vexicons and the Spectral Hand itself for one ultimate showdown to save all of Gemina with the temporary strengthened mystical power of their Dragon, Wolf, Phoenix and Unicorn bracers via their mystical Lances of Justice, as the recently restored Queen Goodfey had given the blueprints for fully creating them (off-screen) earlier.
Queen Goodfey accompanies her fraternal twin daughters (riding alongside Zarya on Archer) and their two best friends on their ultimate mission to obliterate the Spectral Hand from the plane of existence, but this makes Arkayna feel quite resentful towards Zarya, as their mother is paying more attention to her long-lost daughter rather than her. However, it is Zarya's instincts and resourcefulness that put together a force of incredible strength to finish off the ravening beast of the Spectral Hand, defeat the Vexicons, and save all of Gemina.
Final Appearance of Characters
|Arkayna||Ends up becoming resentful of how Queen Goodfey pays more attention to Zarya rather than her.|
|Proxima||Does not any involvement during the ultimate showdown between the Vexicons (her own creations) nor the beast of the Spectral Hand.
She is quite moved when Nova Terron chooses to step down as leader of the Astromancers and gives the position of Star Mistress to her by giving her the powerless Codex and untainted, gold Dragon Disk.
|Vexicons||Become much stronger as the Spectral Hand beast, too, grows in considerable power. They taunt the captured Mysticons and recently restored queen for their heroic efforts against them.
Eartha fully embraces her good heart and helps humiliate her fellow Vexicon "sisters" by taking off Mallory's pride and joy- her ice white hair. She stays with Emerald, who revitalizes her core stone, while the others are imprisoned for their crimes, in some unknown part of Gemina, per King Darius and Queen Goodfey's orders.
|Deeva||Is seen to be imprisoned in a pink energy cage, along with a bald Mallory, Kasha and Willa, who are all imprisoned per the order of King Darius and Queen Goodfey, in the throne room.|

|Queen Goodfey||Her brief memory of baby Zarya having been returned to her (off screen), she accompanies her twin daughters and fellow Mysticons on their ultimate mission to exterminate the Spectral Hand and stop the Vexicons. She becomes excited at the prospect of having her long-lost younger twin daughter returned to her, that she somewhat ignores Arkayna.
She later apologizes and resumes her role as Queen of the realm of Planet Gemina.
|King Darius||Remains with Malvaron, the Goldenbraids, Astromancers and citizens to fend off the tentacles of the Spectral Hand beast. He uses a sword in combat and tries to get his selfish son Gawayne to help him.
Afterward, he admits he is proud of Gawayne and resumes his royal role as King of Gemina.
|Gawayne||Reunites with his father since being turned to solid bone many months ago.|
|Stormy||Is happy to see Choko and the Mysticons again. She tries to get her unborn brothers and sisters through the time-controlling portal, but is stopped by Mallory.|

|Kelpie Truefin (cameo)||Watches as Zarya hurls the fragment of the evil mask into the Rift of Ruin, destroying it once and for all.|
|Dragon Mounts (debut & final appearance)||Four baby dragons, from within the dozens of dragon eggs, who accelerated their babyhood to adulthood by going to the Ever Realm, as time flows much faster there.
Each has the color of each Mysticon's signature color: light green for Arkayna, pale blue for Zarya, light orange for Piper and light purple for Emerald, and can emit powerful blasts of multicolored fire of said colors from their mouths.
