>>6163567Using his new body, he drops fliers all over the city, attracting the attention of Shūta Gō and Bullhorn, the last Headmaster Juniors who haven't found employment. They show up at the company alongside many others and, despite finding their new boss demanding absolute loyalty and threatening anyone who opposes him with death, accepts the job for the sake of the transtectors. The employees begin transporting cargo far and wide thanks to their shuttle modes allowing them to bypass traffic jams.
However, Shūta and the rest soon find themselves overworked, with Astrotrain refusing to let them rest, eat or go home. He reveals that they're not his employees but his slaves, and activates restraint devices that locks the Headmasters to their bodies. He then turns on Tarantulas and blasts him before sending his slaves to attack the Autobots as the first step towards his conquest of the Legends Universe and creation of his empire. Unfortunately, his plan backfires when the exhausted, starving Headmasters prove unfit for combat and begin collapsing—in fact, their bodies are so low on energy that the restraint devices deactivate! The Headmasters run off, leaving their transtectors crashing into Astrotrain and burying him. With his ambition in ruins, Astrotrain ends up using the last remaining transtector to run a commuting service instead.
Save for that last bit, that guess work I put up was pretty close.
