In G1, we finally got a Spike figure in the guise of Cerebro's Headmaster. Today, IDW's G.B. Blackrock is Alpha Trion's Headmaster, Sovereign. My question then is, who else could be worked in as a Headmaster? Certainly, Daniel as Arcee's Headmaster seems an obvious choice. Maybe Dr. Archival as Starscream's? What say you?
