Hydrax Speedway

The Hydrax Speedway was a major center of cultural diversion and entertainment during the last few years before the Great War.

Hydrax Speedway had a variety of racing teams. One of them was named Team Velocitron, presumably after the lost colony world. The speedway itself fell early on in the war to a series of Decepticon strikes, which leveled it. However, they were ultimately driven off by the Autobots, one of the first Autobot victories in the war.

Many years later, Jazz claimed that the surface of Velocitron proper reminded him of the Hydrax Speedway, albeit on a grand planetary scale.
