Kangar-Roo is one of the earliest enemies of the Just'a Lotta Animals. They battled him to a stand-still, although he managed to make them captives of his "slave ship of space." Hearing that he was returning with an interstellar armada to attack Earth, the JLA sent their newest members after him with the hopes he would be unprepared for their powers: Elong-Gator, Green Sparrow, Hawkmoose, The Item, Martian Anteater, Rat Tornado, Stacked Canary and Zap-Panda. This left the original members vulnerable to an attack from Feline Faust during the Crisis on Earth-C.
