During an interivew with Guillermo del Toro about his new TV series The Strain, the Pacific Rim creator and director spilled a few beans about the upcoming Pacific Rim animated series.
The animated series will take place between the movie Pacific Rim and its sequel Pacific Rim 2. It's being described as a long arc (linked episodes) instead of episodic (individual "monster of the week" episodes), running for 13 episodes. Characters from the first film will show up in the series, but will take a backseat to a new set of younger characters. The series will also feature mostly new Jaegers and new kaiju. del Toro also wants to explore aspects from the film including the drift (synchronized link between minds) and the precursors (those who controlled the kaiju).
The animated series is currently deep in the development process. They are in talks with a few Japanese companies for animation, and shopping around for writers and showrunners. They are also not set with a network that will show the series but del Toro described himself as being open and wants a "place that can give it a proper presentation and can advertise the creation of the series".
The Pacific Rim animated series should be airing sometime before Pacific Rim 2 hits the theaters April 7, 2017.
