After Slymenstra Hymen gives birth to Oderus's baby, Cardinal Syn sends his Synnite warriors to come and claim it. As it turns out, Syn is powered by a babies with high levels of Jizmoglobin, and thus feasts on the child. When he arrives he has GWAR nearly defeated; however, they turn the tables on him and claim victory...Techno Destructo hijacks Syn's ship and crashes into him with it, but Syn fires lasers at GWAR and buys enough time to escape.
