Marucho and Preyas are dropped somewhere in the "World of Tests," and they wander aimlessly trying to find the other Brawlers. They encounter a dehydrated old frog-man who sends them on a quest to bring him water. Marucho agrees, and after a lot of hardship, they succeed. This strange thirsty creature reveals himself to be Frosch, the ancient Aquos soldier. He explains that Marucho's test is about to begin, and presents Marucho's opponent... himself! Or more accurately, the Marucho that once was. During the course of the ensuing Brawl, Marucho must come to terms with the "self" that he despises. And Preyas must come to terms with the agony he finds himself in... which turns out to be labor pains! Preyas "gives birth" to Angelo and Diablo, who, along with Preyas, represent the evolved Preyas.
