Jiou Renzu Zakeruga is one of Zatch's spells. It creates a large, serpentine dragon made of lightning with four large blades on the sides of its head, and large scales at various points on its body, two comparatively small clawed hands, hard scales on various regular parts of its body, and many spikes on its tail. The slim form makes the dragon very aerodynamic and agile, allowing it exceptional speed; it attacks using this speed and by shooting its horns and scales. It can also function as a sort of drill as it did in its first use, to help Ponygon and Kafka Sunbeam escape from Shin Kuria Seunousu Baadorerugo's final attack.
