|~ Crustor's final words before his death|
Crustor is a fire/crust-themed Nighlok who wields a sword in battle and can shoot fire from his body.
Serrator, his master, gave Crustor the job to find the Bullzord so that it can be part of a bigger plot that he has planned to split open the world. Crustor targeted a boy named Cody whose family had guarded the seal that contains the BullZord in a plot to gain control of the BullZord for Serrator.
Crustor follows Cody to where the BullZord is sealed where he releases the BullZord. When the BullZord is freed and runs rampant, Crustor plans to find a way to capture the BullZord and Cody. Crustor orders the Giant Moogers to capture the BullZord and Cody but to leave them unharmed. With the Samurai Megazord and the claw battlezord competing against them to capture the Bullzord. When the Moogers fail, Crustor states that capturing the Bullzord will be tough enough and tells Master candied that he will go after the BullZord again. Crustor and the Moogers track the BullZord and end up fighting the Samurai rangers where Crustor proceeds to go after the BullZord with Jayden on his trail.
Crustor infiltrates the BullZord as Jayden also enters the BullZord where he fights Crustor. As Jayden fights Crustor, the BullZord is heading straight towards the cliff. Upon knocking down Crustor, Jayden gives Cody a disk which combined with Cody's symbol power to tame the BullZord while he continues to fight Crustor as Jayden assumes his Super samurai mode and knocks him out of the BullZord destroying him.
After the BullZord is tamed, Crustor grows to giant size. After Cody gets to safety, Jayden ends up being congratulated by the Grand shogun and transforming the BullZord into the Bull Megazord and manages to kill Crustor with the Revolving Laser Blaster and Final Strike attack.
