Transmigrating to the world of Ultraman Gaia, Morita Yuzuki foresaw that because of her intrusion, Zog would be so powerful that he could defeat Gaia and Agul in one move. She felt despair at this, but looking at the Dark Spark in her hand, she felt she could do it again. With each monster-snatching victory, she acquired the Five Emperors and the Greza Spark Doll, accumulating more and more Spark Dolls. She resolved the conflict between Gamu and Fujimiya, obtained the Gaia Spark Doll and the Agul Spark Doll, unified the Alchemy Star, and researched the Dark Spark. When the invincible Zog descended, he was beaten to his knees by Yuzuki's "righteous mob attack." She raised the Dark Spark, smiling, "Another addition to my collection."
