G1 Optimus Prime got killed again. This time by the Vector Sigma explosion in the Headmasters cartoon.
When I watched the first episode of Victory, I remember a different-looking Optimus Prime being a character that was pushed out of leadership of the Autobots by a new character. I think his name was Star Saber.
How did Optimus Prime get brought back to life?
Optimus didn't come back to life, that is God Grini, who was a human to start with, then he found the bracelets inside of the cab of his truck, putting them on, enabled him to become the enegine of the truck and it transforms into a robot, later in the series (Masterforce) he gains the first trailer and becomes Super Grini and with God Bomber (second trailer) he becomes God Grini, at the end of the series, the humans are spilt from their robot partners indefinely and the robots take on their personalites, yet live as Cybertronians, this what transspired in Masterforce, in Victory God Grini is a back ground character for the first half of the show, but later reappears to aid Star Saber, Grini is the Surperme commander of sector two while Star Saber is the Surpeme Commander of sector one and overall commander of the Autobot forces, the show makes no mention of Rodimus or what happened to Fort Max, thou its presumed planet Micron became the new home of the Autobots after Cybertron was destoryed in Headmasters, anyway, with Grini, he kind of shares the same thing as Optimus, AKA noble death, he gets badly injuried in battle that despite all of their advanced medical techonlgy, they cannot heal his body and he would have to remain stuck in a iron coffin unable to do anything but talk, but then taking a idea from the doctor, he under goes a opperation that transforms him completely into another character who not a truck and then becomes a main character for the rest of the show! Effectively, what I believe is in Victory time preiod, Star Saber is the miltray surpeme commander while someone else is the political leader but they aren't shown as the Decepticons are pretty much scattered with a bunch of leaders doing whatever they please with their underlings!
