Zearth

Японское имя:	ジアース
Прозвище:	The Earth

Zearth is the robot assigned to the main characters, which is the name they give it. It is a large black humanoid-type with incredibly long arms and legs. It has extremely thick armor compared to other robots, and it has the ability to jettison any part of its body in any way at will. It can not only locate any of its jettisoned body parts anywhere on Earth, but it can also sense the location of any human on the Earth as well, and that ability can be used to direct any number of its many lasers at any size population and/or any person that the pilot is familiar with no matter where they are on the planet.
