passage: List of Transformers television series
The "Unicron Trilogy" is so-named for the major role that the dark god Unicron plays in each of the three series that comprise it. Spanning twenty years from 2010 to 2030, the trilogy is significant for being a co-production between Hasbro and Takara; the Japanese production team actually wanted to set the series in the Generation 1 continuity, post-"The Rebirth," but this was vetoed by Hasbro's head Transformers design director, Aaron Archer, in favour of completely rebooting the Transformers universe and introducing a brand new continuity for the second time (the first being "Robots in Disguise"). Archer crafted the basic story outline of each of the three lines, with the anime themselves then being written and animated in Japan, but in practice, the Japanese studios did not always follow Archer's design. While each series ran for eighteen months in Hasbro markets, lasting from mid-2002 through 2007, the three were annual affairs in Japan, running from January to December in 2003, 2004 and 2005.
