Abraham Dante

Dante is a human Headmaster in the IDW continuity portion of the Generation 1 continuity family

All hat but no cattle. (He killed the cattle with his bare hands.)

A member of the fairly dastardly mustache-twirling organization known as the Machination, Dante has a vested interest in obtaining Cybertronian technology and reverse-engineering it.

Fiction

IDW comics continuity

Serving under a shadowy mechanoid, Dante reported on the progress resulting from the abduction of Sunstreaker and Hunter O'Nion. He was especially pleased to relate that the conspiracy theorist had taken the Headmaster implantation process like a trooper.
