An A-class heavy metal used by the Poseidal Army.
It is characterized by its rugged design reminiscent of an armored warrior and its skeletal face.
It is a machine with high power and excellent maneuverability, and its versatility is unmatched by any other HM.
It is also the first A-class HM piloted by Gabret Gabree, and the last one he piloted.
All of the Bat-Shu that appear in the film are replicas manufactured by the Poseidal Army, and the whereabouts of the originals, said to have been owned by the Koam Dynasty, are unknown. Even though they are rare A-class HM, a fair number are mass-produced, and over a dozen appear in the film.
