Greatshot

Greatshot was a mercenary that allied with the Autobots, who could transform into six modes, and a recurring character in the anime Transformers: Victory.

Legends
To escape the wrath of the Six Clan that he betrayed and to atone for his past sins, Sixshot faked his death and became the Autobot Greatshot. As part of his redemption, he also resurrected Jack, who he murdered years ago, and the revived bot served as Greatshot's Headmaster for a period that included Greatshot officially joining Star Saber's Autobots and defeating the Concurrence.

Trivia

 * For a while, there was much fandom speculation that Greatshot was an upgraded version of Sixshot, who was depicted as remorseful by the end of The Headmasters. For one thing, they both had the same actor, who voiced them both with a stereotypical samurai movie dialect. The belief that the two were the same would eventually be made canon in the Legends comic, where Greatshot was presented as Sixshot in a new body.
