Anyone fluent in japanese might be able to learn a bit more by watching the original japanese series, but failing that, there isn't anything more to know, just speculation. But speculation is fun 8)It's usually spelt Makara, but it does sound like McKara, and she is more or less human-looking and a red-head. Hmmm...The Imperial Master's servants appear to be taken from a variety of species, possibly some more willing than others. It's interesting that while all the Alliance officers are cybernetically enhanced, only Carter and Orion have actual bug-things on their heads. Maybe Orion's incompetence is actually the result of an internal struggle against his bug?I assume the bugs themselves are cybernetically modified creatures, creatures with useful natural abilities adapted to precisely serve the needs of the Alliance. They don't seem to provide direct control over the wearer, but rather alter their loyalties and personalities.The purpose of Makara's second face is uncertain. Maybe it provides enhanced senses - covering her natural eye wouldn't make much sense otherwise, though possibly that's the easiest way for Alliance tech to access the brain. Maybe also personality backup to give her resistance to brainwashing? Or is it a supervisor - an independently sentient entity rather than an aspect of Makara herself?
