A Headmaster is a type of Transformer where a binary-bonded partner or smaller Transformer serves as a head for the larger robot. They are very unthemely on the MUX, so no, you can't app for one. Sorry.
Pre-Masters (*Masters without Nebulon partners) exist only as background and TP-characters, without partners.
Shattered Glass[]
In this reverse universe, the connection Headmasters have to their smaller partners seems not to go beyond simple personality complement. On the MUX, the small partners are modified tape-bots with two modes:robot and storage device.
