Ask Vector Prime

Steamhammer was created when Megazarak used the Robo-Smasher to implant shell programs into the members of Team Bullet Train. Together with Loco and Astrotrain, he forms Dominus Trannis. The personality component used to make him was quite old, and as a result Steamhammer is a crotchety old train. He remembers fragments of his eight million years as a Predacon but not his original identity.Ask Vector Prime
