The planet is completely covered in factories which produces a constant smog that makes the air on the planet constantly polluted. The planet is visited by the Snow Kids when they go to play a match. Dame Simbai gives the players a gas mask to prevent them from falling ill due to the large amounts of pollution in the air. According to Dame Simbai and Clamp, if the team remained there for a few weeks, there was a high chance of mutation. It seems that a big part of the planet has been blown away.
As seen with the Rykers, the inhabitants of Unadar seem to be agressive and ruthless. However, Dame Simbai stated that this is just because they had to adapt to the harsh conditions of their planet. Their cities are full of skyscrappers, with little to no vegetation. Their hotels have only one TV channel, the Rykers Channel, which transmits footage from the Rykers training sessions.
