Velocitron (known as Speeia in Galaxy Force and Speed Planet in promotional materials) is a fictional planet featured in Transformers: Cybertron 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, and Gigantion. 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." The planet's full, formal name appears to be "Velocitron, the Speed Planet."
