Zarigan (ザリガン Zarigan?, 41) is a giant monster created by Adorocs from fusing a multitude of crayfish into a single giant monster with an acid spray as its weapon. Zarigan overpowered the military before breaking down into its components due to a turtle caught in the mix. Once the fusion is perfected, Zarigan is deployed to attack Shirogane before JustiKaizer is formed to break back up into its components.
