Reincarnated during the war

A young man named Austin Kion was on his way home from work when he saw a child about to get run over by a truck, acting quickly Austin got the child out of the way and took the hit and died, or so he thought he then woke up in a fan made cybertroian body that he made up a few days ago on an asteroid that was passing by Cybertron just as Megatron infused the core with Dark Energon armed with his trusty arm cannon, two katanas, seven transformations, three minicons, his knowledge of the transformer universes, and his earth fighting styles, the four set out to Cybertron to join the Autobots in the war.
