Velocitron

Planet featured in Transformers: Cybertron (known as Speedia in Japan), home to one of four Cyber Planet Keys and ancient Transformer colonies sent to reacquire them. A variable desert planet, it was eventually terraformed into a global race track, with the pursuit of perfect speed and performance the primary motivating force in its government. Disputes are settled in formal races, with the winner claiming victory over the dispute, as well. It's de facto leader is Overdrive (Nitro Convoy in Japan), as she (he, in Japan) is the fastest of all Velocitronian Transformers, with no equal planetside. Holds semi-annual planetwide races to determine the next leader, with the planet's Cyber Key (which is referred to as the 'Planet Cup' by Velocitronians) as the ultimate trophy to the winner. Hot Shot (Exillion in Japan) felt right at home on the planet, and participated in the planetwide race alongside a few of his Autobot comrades, despite reservations by Optimus Prime.
