Primax 1005.19 Gamma (IDW G1 Comics)
Four million years ago, Decimus was a Senator who lived in the halls of Iacon. Orbiting Mining Outpost Croteus 12 was set to be automated, and Senator Decimus was required to go to the site and alert the miners in-person about their new unemployed state. He spoke at the assembly where the miners got angry. One miner began to yell at Senator Decimus on the stage, and the Senator sent in an Autobot guard to deal with him. The miner was killed, which sparked a riot. During the riot, Senator Decimus tried to calm down the situation, but the miner Megatron threw a tool into his shoulder. Decimus was tended to by his aide while the Autobots put down the riot.
Senator Decimus continued to be repaired on his ship on the return to Cybertron, but the prisoner ship Longshot was taken over by the prisoners and opened fire on Decimus's ship. The ship sent out a distress signal, which was later rescued by an Autobot response scrambled by Prowl.
