Ultimate Comics: Thor is a comic book limited series published by Marvel Comics that debuted in October 2010. The series takes place in the alternative Ultimate Marvel universe. Based on the Ultimate Comics version of the Norse god Thor, the series was written by Jonathan Hickman with art by Carlos Pacheco. In an interview, Hickman said that the series would be a prequel to Mark Millar's limited series The Ultimates, "It starts eons ago, in the long ago time of mystic Asgard, and, yes, takes us up to the start of [the first issue of] ULTIMATES. If I do my job well, it should jive [sic] with all the Ultimate Thor things we've seen up to this point." The series also features the debut of the Ultimate Baron Zemo, expands on areas of Norse mythology and portrays the events of Ragnarok. Source: Wikipedia (en)
