TRANSFORMERS: CYBERTRON follows in the footsteps of Transformers: Armada and Transformers: Energon, and, like its predecessors, it's both a TV show and a line of action figures by Hasbro and Japanese toy company Takara. Unlike the others, however, Transformers: Cybertron takes viewers to the final frontier with plotlines that revolve around space travel. A black hole in space has threatened the existence of Transformers from the planet Cybertron, so they emigrate to Earth to seek refuge. There they befriend brothers Coby (voiced by Sam Vincent) and Bud (Ryan Hirakida) and their friend Lori (Sarah Edmondson), who help the mechanical newbies navigate their new home. The only way the gang can stop the spread of the black hole is to collect four Cyber Planet Keys, which are hidden on four different planets: Earth, Velocitron, Jungle Planet, and Gigantrion. The mission would be simple but for the fact that the Transformers' nemeses, the Decepticons, are also after the Keys for their own goal of domination. The race is on, and it leads to a galaxy-wide scavenger hunt as the characters work to identify the disguised Keys.
