Velocitron

Velocitron (known as Speedia in Japan) is a fictional planet featured in Transformers: Cybertron (known as Transformers: Galaxy Force in Japan) and is the location of one of four ancient Transformer colonies that lost contact with the home world of Cybertron long ago, along with Earth, Jungle Planet (Animatros in Japan), and Giant Planet (Gigalonia in Japan). Each of these colonies possess a Cyber Planet Key, containing a fragment of the power of Primus.

The name Velocitron is used infrequently. The planet is more commonly referred to as "the Speed Planet" or simply "Speed Planet."

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 society. Disputes are settled in formal races, with the winner claiming victory over the dispute, as well. Automated repair machines maintain the race courses, which include tracks featuring various enviroments and obstacles as well as simpler straight-forward courses.

The planet's leader is Override (Nitro Convoy in Japan), as she (he, in Japan) is the fastest of all Velocitronian Transformers, with no equal planetside. She holds semi-annual planetwide races to determine the next leader, with the planet's Cyber Planet Key (which exists in the form of a trophy called the Planet Cup) awarded to the winner.

The location of Velocitron was discovered by Vector Prime while studying a copy of the Atlantis Pattern found at a museum in Mexico.

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.
