Cover: Superman, Batman, Wonder Woman, Flash, Green Lantern, Aquaman and The Martian Manhunter the way they should be... as gorillas! (Batman dosn't appear as a gorilla in the story, I guess because he's too good for such things.)Cover Artist: Arthur Adams.
Solovar, the leader of Gorilla City announces that Gorilla City wants end it policy of isolation from the human world and wants to join the United Nations. The world welcomes the gorillas and Solovar becomes an instant celebrity. However, it doesn't take long for poor Solovar to be assasinated, and Gorilla City, under the new leadership of Prince Ulgo, declairs war on the human world! Soon we find out that Ulgo is really the pawn of none other than Gorilla Grodd and a group known as The Simian Scarlet.
Soon, the Justice League is summoned to Gorilla City to act as intermediaries between the gorillas and the humans. But as soon as they arrive, Superman, Wonder Woman, Flash and Aquaman are attacked and turned into gorillas! They now want to fight alongside the gorillas agains humankind, until the Martian Manhunter (who has also been turned into a gorilla) arrives and telepathically reinforced their "orignal identiry-structures." Martain Manhunter manages to get an unused "gorilla bomb" (used to turn humans into gorillas) and he and Batman analyse to find a way to reverse the gorilla transformations. Finding no results, Martian Manhunter seeks the help of Animal Man, who, at times, is a babbling idiot, probably still recovering from having to be in a crappy Vertigo book.
Later, the gorillas attack the U.N., and the "JLApes" rush off to stop them. However, they're too late, and the gorillas drop another gorilla bomb on the U.N., turning all the ambassidors (including Chico and Groucho Marx as the leaders of Freedonia) and Green Lantern into gorillasand the all fight, fight, fight! While fighting in three continuous double-page spreads, gorillas say things like, "Groot!" and "Moomba!" and Green Lantern yells, "It's a madhouse!" Martian Manhunter and Batman arrive with a device intended to change the superheroes back to normal, but he has to use it to revert the world leaders, leaving our heroes still as gorillas (Yay!).
Martian Manhunter revleals that a mind scan of Ulgo revealed that his Simian Scarlet forces plan attacks on (convienently enough) Themyscira (home of Wonder Woman), Atlantis (home of Aquaman), Central City (home of The Flash), Bludhaven (sort of new home of Batman), Metropolis (home of Superman), so the team has to split up to put an end to ape tyranny!
