27-Series Asura are early experimental combat Realian models, based on data taken from Febronia, but it is unknown if this means they are also transgenic-type Realians or partially human. They were developed in Labyrinthos and designed by Kevin Winnicot and Joachim Mizrahi. Their ability to judge and adapt to situations is greater than previous combat Realians; they are designed to be able to handle any given situation using their own judgement. They are difficult to calibrate, however, and are still in the testing phase.
