According to its profile, the GC Master possesses a superior gravity control output that only those considered true masters of Extreme Gear are able to handle.
The GC Master is very similar to the Night Sky from the same game in terms of shape. Like most other Board type Extreme Gears in Sonic Riders: Zero Gravity, the GC Master has a board-like shape, but is thicker and smoother than that of the Board types seen in Sonic Riders. It is primarily colored black, with a silver-colored triangle-like shape on the front and another silver area behind the rear and possesses two exhaust ports on both sides of the rear where each half of them are colored black and silver as well. It is as well decorated with yellow highlights on the top surface, along the sides and on the exhaust ports and has two silver blue foot panels on the top.
Abilities and traits
As a Board type Extreme Gear in Sonic Riders: Zero Gravity, the GC Master is well-balanced in its attributes with average statistics, and is suited for general riding.
As a more advanced version of the GC Booster, the GC Master possesses slightly higher stats that the former and can reach even greater velocities when receiving the speed boost from Gravity Control. Aside from this, the GC Master possesses no unique abilities of its own.
