Autobots

Optimus Prime

Bearer of the Matrix of Leadership. Believes freedom is the right of every sentient being and is always first to stand between the defenceless and danger.

Where he comes from

Cybertron. In most modern versions he is an ordinary worker, archivist or miner from Iacon named Orion Pax, chosen by the Matrix of Leadership as the new Prime.

Story

Orion Pax never dreamed of power. He believed Cybertron could be changed through words and honesty, which is exactly why the Matrix chose him. As Optimus Prime he led the Autobots against his former friend Megatron in a war he never wanted.

After his home planet dies, Optimus searches for a new home for his people and finds it on Earth. He falls and returns more than once, yet always stays the same: a leader who is first to take the blow and last to leave the battlefield.

Fan prequel: «Orion's Last Record»

An original story by this site. Not part of the official canon.

On the night before the Matrix spoke to him, Orion Pax stayed in the Iacon archive longer than anyone. He was copying an old mine log in which workers complained about cave-ins — a log the Senate had ordered erased.

"Why keep something nobody will read?" asked the night guard. "Because one day someone will want the truth," Orion replied. "And truth has no right to vanish just because it is inconvenient."

He hid the copy in the archive's deepest cabinet and left at dawn. That same morning a light unseen for millennia blazed over the square, and a voice like a bell called him by a new name. Many years later Optimus Prime would return to that cabinet — and find the log exactly where he had left it.
