The "monkey business" gets serious for the JLA in the concluding chapter of "JLApe: Gorilla Warfare!" In a JLA adventure starring J'onn J'onzz, the Martian Manhunter uses his considerable detective skills as he interviews every ape-connected denizen of the DCU, from Angel and the Ape to Detective Chimp to Monsieur Mallah, to get the inside story on the greatest ape villain of all time, Gorilla Grodd! But will his newfound insight be enough to stop Grodd's master plan to turn all humans into faithful gorilla soldiers? It all comes down to Grodd's awesome "Force of Mind" versus the Manhunter's vast telepathic powers in a cosmic battle for control of the planet, as the wildest Annuals event in history swings to its chest-pounding, fang-bearing conclusion!
