Question: The toy line associated with Secret Wars has headquarters in what US state?
Context: Galaxy Serie was a science fiction themed toy line produced by Italian company Atlantic from 1978 to the early 1980s.  It was commercialized in several European countries, including Italy, France, and Greece.  The toy line comprised a series of action figures and a set of vehicles, as well as a chess-inspired board game called Cosmo Checkers ("Cosmoscacchi" in the italian edition) that employed the Galaxy action figures as pieces.  Most boxes included comics booklets describing the setting and characters of the toy line. The Secret Wars toyline was a short lived tie-in to Marvel Comics' "Secret Wars" comic book mini-series.  The line was produced by Mattel and saw two series of action figures released (along with vehicles and playsets) in 1984 and 1985, as well as a third series of figures released outside North America.  Figures typically came with shield accessories that could hold lenticular images.  Several of the characters in the mini-series never appeared in the toyline, while characters and vehicles not appearing in the mini-series appeared in the toyline. Marvel Super Heroes Secret Wars, commonly known as Secret Wars, is a twelve-issue American comic book crossover limited series published from May 1984 to April 1985 by Marvel Comics.  The series was written by Jim Shooter with art by Mike Zeck and Bob Layton.  It was tied to the same-named toyline from Mattel. "Secret Wars" is a 2015 comic book storyline published by Marvel Comics.  It recalls the original, similarly-named 1984–1985 miniseries.  Released on May 6, 2015, the storyline includes a core "Secret Wars" mini-series, written by Jonathan Hickman and drawn by Esad Ribić, which picks up from where the "Time Runs Out" storyline running in "Avengers" and "New Avengers" ends. Eagle Force was a 2+3/4 in die-cast action figure military-themed toy line marketed by Mego Corporation in the 1980s in the United States.  Produced during Ronald Reagan's first term as president, the Eagle Force toy line was marketed to send the message that the United States wasn't going to be "pushed around" anymore.  Designed by Bill Baron and Paul Kirchner, Eagle Force was similar to the toy line, which was being developed by Hasbro during the same period. Transformers: Generation 1 (also known as Generation One or G1) is a children's toy line that ran from 1984 to 1992 and was produced by Hasbro.  It was a line of toy robots that could change into an alternate form (vehicles such as cars and planes, miniature guns or cassettes, monsters, and even dinosaurs) by moving parts into other places, and it was the first line of toys produced for the successful Transformers toy and entertainment franchise.  The line was originally called "The Transformers", with "Generation 1" originating as a term coined by fans of the toys when the toy line was released in 1992.  Hasbro eventually adopted the term "Generation 1" to refer to any toy produced in that era. Mattel, Inc.

"Death of X" is part of a series of story arcs that have impacted the Inhumans and X-Men titles after Secret Wars ended and Earth 616 was restored along with being related to the events of the Infinity, Inhumanity, and Inhuman story arcs.  This miniseries event answers the question about what really happened between Cyclops and the Inhumans in the eight-month gap between "Secret Wars" and the All New, All Different lineup of comics.  This limited series event serves as a prequel to the series "Uncanny Inhumans", "Extraordinary X-Men", and Volume 4 of "Uncanny X-Men", along with impacting the plot to "Civil War II: X-Men" and ultimately serving as a precursor to lead into the major crossover event "Inhumans vs. X-Men". The Beyonder is a fictional cosmic entity appearing in American comic books published by Marvel Comics.  Created by writer Jim Shooter and artist Mike Zeck, the Beyonder first appeared in "Secret Wars" #1 (May 1984) as an unseen, nearly omnipotent being who kidnapped the heroes and villains of the Marvel Universe and had them do battle on another planet called Battleworld.  He later appeared in a more antagonistic role in the 1985 sequel "Secret Wars II", in which he took human form, and threatened to destroy the Marvel multiverse.  Although he first took on a physical, humanoid form in "Secret Wars II" #2, it was in "Secret Wars II" #3 that he took on the permanent form in which he remained for the rest of his existence, that of a Caucasian human male with curly black hair.  Although the character met his demise at the end of "Secret Wars II", he has subsequently appeared in stories well into the 2000s, although in greatly diminished form.
