Optimus Prime Ice Sculpture By Antti Pedrozo And Michel De Kok

In Marvel Comics' comic series, before the Great War broke out on Cybertron, the robot who would be Optimus Prime (before he received the Matrix of Leadership from Sentinel Prime) was a Transformer of note, displaying his skills in the Infraformers Sharpshooting Competition. Subsequently, when the war began, Prime quickly made a name for himself as a combat leader of the Autobots.
On a mission with the Triggerbots to stop Megatron from claiming the Underbase, Prime was forced to jettison the massive databank into space to prevent anyone from acquiring its power, and with this action, he proved his wisdom and skill to the Autobot Council of Elders. This led to even more rapid advancement, eventually leading him to field command over the Autobot armies.
Four million years ago, Cybertron — shaken from its orbit and drifting through space — came under threat when it floated into the path of an asteroid swarm. Prime led a group of elite Autobot warriors on the Autobot starship, the Ark, on a mission to destroy the asteroids, and although successful, in the aftermath of this mission the Ark was attacked by Decepticons, hoping to overcome their weakened foes. Intent on keeping the secrets of the Ark from the Decepticons, Prime set the craft on a suicide course, crashing it into the prehistoric planet Earth.
In 1984 A.D., a volcanic eruption re-activated the Ark, which in turn brought the Transformers back on-line. Prime led the Autobots in their opening battles to prevent the Decepticons from plundering Earth's resources, but following their initial victory, the Transformers were all deactivated by Shockwave. Prime was decapitated by Shockwave, and had the energy of the Creation Matrix leeched from his mind to give life to Shockwave's creations, the Constructicons (although Shockwave was unaware that the Matrix was not merely a program in Prime's mind, but a physical object in his chest). Before Shockwave could give life to his next Decepticon, Jetfire, Prime transferred the Matrix energy into the mind of Buster Witwicky, who used the energy to turn Jetfire on Shockwave, allowing Prime to reclaim his body and retake leadership of the Autobots, giving Jetfire true life as a reward.
