-Purge the Great Purge the Great, or Great Purge, is the final boss of Space Channel 5 Part 2. Once Dancing Purge’s Ballistic Groove Gun has been charged with enough dance energy from his captive audience, he uses that power along with Peace’s song to become an incredible force to be reckoned with. This super duper suit is able create Dance Dimension X, the place where Purge shows Ulala his true power. With strong electrical orbs being hurtled towards Ulala, it seems she’s finished. In fact, she is. Purge sends nine orbs filled with a strong electrical current at Ulala, presumably killing her.
