summafy from tfwiki In the year 2022 of the G1 World, Marissa Faireborn is leading an Earth Defense Command force against the last holdout of the Concurrence when she\'s assisted by a mysterious starship. The Autobot First Army are similarly aided by a tank while battling on the surface on the moon, and by the end of the battle, they have collected reports of six of these mysterious Transformers appearing out of nowhere to help them. Star Saber, returning after being cleared of false charges, clears up that their benefactor is not six warriors, but one warrior with six modes: his friend Greatshot.Months earlier, Star Saber thanks Sixshot for breaking him out of jail by gifting him a new transtector, telling him to use it to take on the new identity \"Greatshot\" in order continue to fake his death and avoid the Six Clan\'s wrath. Sixshot accepts his offer and promises to join the Autobots in the future, but for now he remains in the Legends World to work with Giga on using Shinchōkon to resurrect Jack. As Overlord, Giga infuses Sixshot with the energy and explains that they will replicate the miracle of Megatron returning to life in a smaller body, but there is a caveat: this method of resurrection requires a body, so Sixshot will have to give his up for Jack to inhabit. The process succeeds and Jack comes back to life as a Headmaster while Sixshot\'s soul is instead transferred into the transtector, fully turning him into Greatshot. Remembering his evil deeds, particularly his role in Jack\'s death and yet how Chromedome was still willing to help him, Greatshot drives Jack to Chromedome and watches their tearful reunion. Since Greatshot still needs a head to function properly, Jack magnanimously decides to be his Headmaster partner and returns to the G1 World where the two are embroiled in the battle with the Concurrence.Greatshot is uninterested in helping the EDC, believing himself unsuited for being a hero, but Jack convinces him to see it as atonement, guilting him by reminding him he\'s talking to someone he murdered. He relents and travels to the battlefield, where he\'s reunited with Star Saber and allows him to ride his rhino mode into battle before borrowing his swords and using them to destroy the Concurrence\'s base. With the Concurrence defeated, Spike reclaims his spot as Galactic Peace Alliance chairman and Daniel and Bumblebee return safely as well. Greatshot eventually gets his own head and becomes a proper Transformer again, allowing Jack to return to Chromedome\'s side, and goes on to fight the Decepticons alongside Star Saber. In 2026, he is gravely injured during the Silvart War and again accepts his fate as atonement for his past, muttering goodbyes to Daniel, Star Saber and Jack as he awaits his death. To his surprise, however, those very people and many others suddenly come to his aid, having been looking for him since his disappearance. Slipping back into his old Sixshot speech pattern, Greatshot admits that having friends isn\'t so bad.
