Ex-Machina

The ExMachina (機凱種, エクスマキナ) appear to be a race of cybernetic life forms that appear in volume 6 of the light novels, not much is currently known about them until the translations appear except that they are a cybernetic race as deduced by their name and the appearance of a cybernetic character in the 6th volume. The only known ExMachina is Shuvi.

Strengths
It is said that they are able to replicate any attack launched at them after less than 10 seconds after seeing it. They were even able to fire back an attack from Artosh.

Weaknesses
Although they are able to replicate and counteract attacks from opponents with ferocity, they are a defensive race in nature. If not provoked, they have no aggression towards the person or group. Therefore, they could potentially lose if they are beaten by the first move or if an unpredictable method they have not seen before is used before they can fully assess and correct the situation.

History
During the Great War, they were created by the Old Deus to kill the other Gods.

Trivia
