The show takes place ten years after the finale of Micron Legend, opening in an age of peace on Seibertron and Earth which is destined not to last long. Superlink pits the Cybertrons against an array of villains: the reborn Galvatron , the barely functional Unicron, and the mysterious Alpha Q and his Terrorcon minions.
Transformers: Energon, known in Japan as Transformer: Superlink, is the 2004–2005 Transformers toyline, animated series and comic book series, another co-production between Hasbro and Takara and a direct sequel to Transformers: Armada. It is also the first Japanese Transformers show where the Transformers are computer-generated, in a cel-shaded technique similar to the Zoids anime, which was a trend that would continue into the next series, Transformers: Cybertron. In this series, the Transformers' primary gimmicks are the Autobots' ability to combine with partners of the same size, the Decepticons' ability to use powered up forms, and the addition of Energon weapons and stars that can be placed on any Transformer. Mini-Cons, from the previous line, are still present, but all Mini-Con pegs are "dead", and they do not activate a function on the toy.
