JLA/Avengers

JLA/Avengers (issues #2 and 4 are titled Avengers/JLA) is a comic book limited series and crossover published in prestige format by DC Comics and Marvel Comics from September 2003 to March 2004. The series was written by Kurt Busiek, with art by George Pérez. The series features the two companies' teams of superheroes, DC Comics' Justice League of America and Marvel's Avengers.

==Publication history== In 1979, DC and Marvel agreed to co-publish a crossover series involving the two teams, to be written by Gerry Conway and drawn by George Pérez. The plot of the original crossover was a time travel story involving Marvel's Kang the Conqueror and DC's Epoch. Writer/editor Roy Thomas was hired to script the book based on Conway's plot, and although work had begun on the series in 1981 (Pérez had penciled 21 pages by mid-1983) and it was scheduled for publication in May 1983, editorial disputes – reportedly instigated by then-Marvel editor-in-chief Jim Shooter – prevented the story from being completed. The failure of the JLA/Avengers book's publication also caused the cancellation of a planned sequel to the 1982 crossover issue The Uncanny X-Men and The New Teen Titans.
