Hardhead

Hardhead was a badass Autobot soldier who sometimes worked with the Autobot Arcee. He was part of a team sent to scout out Jhiaxus' Cybertronian empire when he and his team was captured, he was interrogated and killed shortly afterwards. Arcee was the only member of the team to survive, and escaped and avenged them by destroying Jhiaxus' empire and by personally killing him on a barren moon. Hardhead also liked to sing when he was high on Engex.
