Planet Z, or Xrghthung, is the residence of the Evil Emperor Zurg and his minions.
The planet itself is red and purple, has three moons, and often has storms around it.
On the surface, the sky is red-tinted and cloudy, and the capitol (at least in the area where Zurg lives) is technologically advanced, rather close to Capital Planet's level of technology. However, factories with smoke emitting from them can also be seen, suggesting heavy use of industrial technology and factories.The flora and fauna of this planet are never seen, and the main inhabitants (those not enslaved by the emperor) are unknown.
Exactly how Zurg came to power is unknown. It is also unclear if Zurg rules through monarchy, or some other form of government.
The main inhabitants of the planet are never seen, but Zurg's henchmen (presumed to be from the planet) are.
Brain-like creatures who use robotic bodies to move around. They are excellent technicians and inventors, designing many of Zurg's weapons for him.
Insect-like creatures similiar to LGMs, save for having their shared hive mind.
Constructed to serve Zurg. Most notable among the robots are the Hornets, who serve as Zurg's foot soldiers.
Zurg's species is unknown, but it is assumed that whatever his species is may be native to Planet Z.
Nothing is truly shown about their lifestyle, although it is assumed the residents live under tyranny.
- The first few letters of the planet's name, "Xrghthung", could be pronounced "Zurg". It is not known if the planet was named after Zurg, or vice-versa.
