<P> In need of a new secure headquarters, the Justice League moved into an orbiting satellite headquarters in Justice League of America #78 (February 1970). The Elongated Man, the Red Tornado, Hawkgirl, Zatanna, and Firestorm joined the team, and Wonder Woman returned during this period . </P> <P> Len Wein wrote issues #100--114, in which he and Dillin re-introduced the Seven Soldiers of Victory in issues #100--102 and the Freedom Fighters in issues #107--108 . In the fall of 1972, Wein and writers Gerry Conway and Steve Englehart crafted a metafictional unofficial crossover spanning titles from both Marvel and DC . Each comic featured Englehart, Conway, and Wein, as well as Wein's first wife Glynis, interacting with Marvel or DC characters at the Rutland Halloween Parade in Rutland, Vermont . Beginning in Amazing Adventures #16 (by Englehart with art by Bob Brown and Frank McLaughlin), the story continued in Justice League of America #103 (by Wein, Dillin and Dick Giordano), and concluded in Thor #207 (by Conway and penciler John Buscema). As Englehart explained in 2010, "It certainly seemed like a radical concept and we knew that we had to be subtle (laughs) and each story had to stand on its own, but we really worked it out . It's really worthwhile to read those stories back to back to back--it didn't matter to us that one was at DC and two were at Marvel--I think it was us being creative, thinking what would be really cool to do ." Justice League of America #103 also featured the Justice League offering membership to the Phantom Stranger . Len Wein commented on the Phantom Stranger's relationship with the JLA in a 2012 interview stating that the character "only sort of joined . He was offered membership but vanished, as per usual, without actually accepting the offer . Over the years, other writers have just assumed (he) was a member, but in my world, he never really said yes ." Issues #110 (March--April 1974) to #116 (March--April 1975) of the series were in the 100 Page Super Spectacular format . Libra, a supervillain created by Wein and Dillin in Justice League of America #111 (May--June 1974), would play a leading role in Grant Morrison's Final Crisis storyline in 2008 . </P> <P> Writers Cary Bates and Elliot S. Maggin wrote themselves into the 1975 JLA--JSA crossover in issues #123 and 124 with Bates becoming a supervillain . </P> <P> Wonder Woman rejoined the team following a major two - year story arc, largely written by Martin Pasko . To prove her worthiness to rejoin the JLA, Wonder Woman voluntarily underwent twelve trials analogous to the labors of Hercules, each of which was monitored in secret by a member of the JLA . After the conclusion of the storyline in Wonder Woman #222, the character's return to the JLA occurred in a two - part story in Justice League of America #128--129 (March--April 1976). </P>
