Justice League United began its development in the summer 2013 after "
Forever Evil" was to be finished during its run at the time. Writer Jeff Lemire and artist Mike McKone were assigned in taking over
Justice League of America, with the series being retitled
Justice League Canada, as the series was to take place in Canada.
Adam Strange and a brand new character of Canadian origin were expected to join the team.
Animal Man became a part of the team, when his
eponymous solo title was canceled in December, which was also written by Lemire.
Justice League of America was instead relaunched in April 2014 as
Justice League United with a zero-issue. The team's Canadian addition was revealed to be Miiyahbin Marten, a 16-year-old
Cree teen from
Moose Factory with the codename Equinox. Her powers stem from the Earth and change with the seasons.
Jeff Parker took over as writer with issue 11. DC canceled the series with issue 16 in December 2015, with news outlets citing low sales as the most likely cause of cancellation. ==Team roster==
