Machina was the former home planet of the Metal Cardbots, a race of sentient machines led by Deus Machina. At some point in time, the planet was destroyed, forcing the surviving Cardbots to seek refuge on Earth.

The reason for the planet’s destruction remains unknown.

Composition

Machina shares a number of similarities to Earth. A variety of biomes populate the planet, including deserts, oceans, and mountains.¹ The planet’s atmosphere and weather allow Cardbots to live safely on its surface. However, it is implied that the planet does not have a magnetic field², making it inhospitable for humans. No organic life forms are known to exist on Machina.

In many parts of the planet, crystaline structures consisting of Machinasium jut out of the ground.

It is unknown whether forms of life other than Cardbots existed on Machina, though Gremlins are said to have lived there.
