Sixshot:
In the G1 World, former Decepticon ninja staff officer Sixshot surrenders to the Autobots to be imprisoned at the Planet Micro Satellite Penitentiary. Recognizing him as a member of the dangerous Six Clan, the personnel neutralize his six-changing ability by removing his head and converting it into a micro-sized robot mode, unaware that Sixshot has already been ostracized from the ninja clan by joining the war, going against their rules to stay secret. This is all according to Sixshot's plan, however, as he's working with Daniel Witwicky to infiltrate the prison and break out Star Saber, unjustly imprisoned by the compromised Galactic Peace Alliance. The Sixshot body held within the prison suddenly falls to pieces as Daniel pilots his real body, already modified into a transtector, out from the lava underneath the facility. Escaping into space with Sixshot and Star Saber, he explains that they'll hide from the Alliance in the Legends World.
On arrival, Daniel seeks out Chromedome, who agrees to shelter him and Star Saber but refuses to help Sixshot, murderer of his friends Abel and Jack. Sixshot turns to leave, but Chromedome changes his mind and lets him stay... in exchange for working as his art assistant, as Chromedome has quit his job to become a full-time manga artist. Sixshot doesn't fully understand the "moe" artstyle he helps ink, but reflects that it's good that Chromedome has found a way to reach out to people's hearts, seeing as he himself is only good at killing. He also notes a certain resemblance between Chromedome's original character and Arcee, causing the Autobot to grow flustered while the others tease him about his old crush. Suddenly, Ultra Magnus arrives on their doorstep, having been tasked by the Galactic Peace Alliance with capturing the fugitives. Not wanting to cause any trouble for his benefactor, Sixshot decides to act like he's been holding Chromedome hostage and confront Magnus while Daniel and Star Saber escape.
Ultra Magnus is happy for a rematch with his killer, positive that he won't lose with power of Alpha Trion, Matrix, on his side. Sixshot merges with his transtector and attacks the Autobot using several of his modes, intending to finish him off with his seventh Wingwolf mode once again, but this time Ultra Magnus is able to catch him out of the air and throw him to the ground. They both transform into their car modes and ram each other head on, and when the dust from the collision settles, Sixshot stands victorious... until he's suddenly impaled from behind by Nightbird, agent of the Six Clan, as punishment for defying them. Daniel rushes out to his friend, but Sixshot accepts his death, considering it just deserts for his evil deeds, and tells Daniel to treasure his life before succumbing to his injuries and exploding.
But that is not the end: a bandage-clad but alive Sixshot later purchases the magazine in which Chromedome's manga has been published and, treasuring the moment of peace he experienced working on it, resolves to repay him. Having learned that the dead can be resurrected in the Legends World, he seeks out Giga for help, wanting to bring back the friends of Chromedome he killed. Giga explains that the power to do so, the spirit energy used by the Zamojin, is none other than Shinchōkon—"God Super Soul"—and questions if Sixshot has the resolve needed to control it.
Doublecross:
The Legends World is visited by White Leo, leader of the Beastformers, exiled from his homeworld of Beast after being defeated by his enemies, the Laser Beasts. He uses six mystical jewels to transform Neo Akihabara City into a jungle and recruit the unwilling local beasts to fight alongside him, granting them Beastformer armor, though the local humans instead end up as naked as animals (and are offended when White Leo calls them "ape-type beasts"). Unfortunately, White Leo finds that he's been followed by his nemesis Tigerburn, Emperor of the Laser Beasts, who explains that the six jewels contain the crystallized power of the Three Wise Ones and that he wants his hands on them. Tigerburn is seated atop Doublecross, to the surprise of his old buddy Repugnus, and White Leo explains that the Monsterbot has been Tigerburn's puppet ever since the Laser Beasts cut his head off, removing his sense of self. Furthermore, Tigerburn reveals that he's modified his body to become completely robotic, used Legends technology to become a Headmaster in order to combine with Doublecross's body, and acquired the most powerful Laser Beast weapon, the Haywire Laser.
White Leo can do nothing but flee from the powered-up Tigerburn, but his younger sister, White Lune, appears before him with Doublecross's severed head and a plan: if the Three Wise Ones once used the jewels to create the Beastformers by giving machines to animals, they should be able to use them to evolve further alongside machines. The jewels emit a light that sucks in the Haywire Laser and merges it with White Lune, who transforms into a robot and knocks Tigerburn's block off. White Leo himself is merged with Doublecross's head, allowing him to transform into it and combine with Doublecross, whose mind(s) is restored in the process. Doublecross and White Lune blow Tigerburn back into his own dimension with a Spark Fire Attack, after which the siblings prepare to return and continue the war back home, but first they stop to apologize to the Legends locals for forcing them to become Beastformers. Upset, Rattrap and Tigatron tell them to consider how things would be if their roles were reverse: how would the Beastformers like it if they were forced to wear nothing but neckties and work as office workers? White Leo and Lune agree that it would be awful.
Misfire:
The buildings in Neo Akihabara City are being bought up one by one by Misfire, whose luck in gambling and the stock market has made him filthy rich. When the 'bot himself appears, throwing money around and demanding to be called "Perfectfire" from now on, Triggerhappy refuses to believe someone as unlucky and prone to missing as him could pull this off. Hot Rod and Shaoshao Li are also suspicious, especially given the presence of Misfire's Targetmaster partner, Aimless, and that night they sneak into Misfire's purchased Trypticon to investigate. Misfire catches them and fires Aimless at Hot Rod, but instead hits Shaoshao, transforming her into an infant! He reveals that Aimless's mutant ability is to shoot through time itself, allowing him to see into the future and get rich, which in turn has afforded him a transtector that he combines with.
Misfire blasts a hole into the future in order to predict how Hot Rod will move, making it impossible for the Autobot to dodge his attacks... but is somehow so bad at aiming that even knowing the future, he fails to hit a completely still Hot Rod and instead ends up blasting all the stuff he's bought, which disappears to when-knows-where. Hot Rod punches his head off and demands he restore Shaoshao to normal, only for Misfire to miss again and hit Hot Rod, "aging" him into Rodimus Prime. Everything is eventually cleared up and Misfire and Aimless are arrested, though Shaoshao is mad at Hot Rod for not making her younger when he had the chance. Unfortunately, the officer supposed to interrogate Misfire is Triggerhappy, who starts teaching his old comrade how to aim instead.
