I have finally found some of the new Titans Return figures. Before spending time with them, let me give
my thoughts on the line as a general idea.
The central gimmick of Titans
Return is that Headmaster: a small robot that transforms into the head of a
full-sized one. Storywise, this concept is slightly complicated by the point of
origin for the story one chooses: in the American G1 continuity, the small
robots were inhabitants of the planet Nebulous, where a civil war had broken
out, not unlike that of Cybertrons’ past. Halves of the conflict ally
themselves with either Cybertronian faction, acting as a second head being
better than only one. Thus, heads and robots remain distinct entities, separate
characters who more or less work together to do the things that the
Cybertronian had been perfectly capable of doing on their own up until now. In
Japan, the small robot WAS the character, with the larger body being an
exosuit-type thing. Titans Return is
predictably sticking with the American version, and so each Headmaster is a
separate character . . . to whatever extent you consider a small robot who
bends over to be an actual character.
