Alpha Trion

Early Life
Alpha Trion's backstory was unknown for many years. It wasn't until the Cybertronian Optimus got the Matrix of Leadership his backstory became clear. The one inside the Matrix to call Optimus the first real prime was Alpha Trion. This made Optimus learn Alpha Trion wasn't his first name. His first name was Alpha Prime. One of the Thirteen Primes.

Alpha Prime was a wise man who served with his brothers. The Thirteen Primes. Their leader Prima always turned to Alpha Prime when he needed guidance. Not much is really known about Alpha Prime more than that he was there to fight The Fallen and to defeat Unicron. Alpha Prime explained to Optimus he then decided to be reborn into a new bot. This bot became Alpha Trion.

Alpha Trion
Alpha Trion kept all his memories from his past life, but he always kept it to himself. He was the one to build the library on Iacon. There he was able to put down the story of Cybertron. Alpha Trion also met the leader of Cybertron before the Great Civil War. This was Zeta Prime. Zeta had found the Star Saber and needed Alpha Trion's help to wield it, but Alpha Trion explained only a real Prime could wield its power. This made Zeta Prime furious as he told Alpha Trion to lock the sword up and never tell anyone.

As years passed by, Alpha Trion got a pupil in Orion Pax. He taught Orion the story of their homeworld and also how to follow his heart. It was also Alpha Trion who rebuilt Orion when he was near death by the hands of Megatron.

During the Great Civil War, Alpha Trion got a new pupil in Hot Rod. Hot Rod was much like Orion Pax which made Alpha Trion give him the Key to Vector Sigma. Hot Rod didn't know this though as the key was put inside his chest. When the Decepticons got to the library, Hot Rod tried to cover the whole library, but in the end, Alpha Trion made Hot Rod escape. Alpha Trion stayed though and was killed by the Decepticon Sixshot.
