Armadeevil

Armadeevil is a Nighlok unknown to Xandred and Octroroo. He goes to the human world and attacked some humans when the Red and Pink rangers showed up and tried to attack him. However, their swords are useless against Armadeevil's shell. The other rangers(except Antonio) showed up and tried everything to destroy Armadeevil's shell, but none of their attacks work. Armadeevil was about to smash the rangers when he dries out, forcing him to go back to the neitherworld. Kevin has a plan to destroy his shell and the rangers plan to try it the next time he comes back. Once Armadeevil is full of water again, he comes back to the humanworld and the rangers showed up. Their plan was first Mike and Emily using their symbol power to create a rock wall, forcing Armadeevil to crash into it. Then Mia uses her Sky Fan combining with Jayden's fire to heat his shell up, then Kevin uses his symbol power to create a tidal wave, splashing Armadeevil with cold water, causing a shock. Kevin then uses the Black Box to go into Super Samurai Mode, using his Super Dragon Splash to destroy Armadeevil. He grows into mega. The Rangers use the Samurai, Beetle Blaster, Swordfish Fencer and Tiger Drill Megazords' finishers on Armadeevil, but they are useless. The rangers then form the Claw Armor Megazord and uses its finisher Double Katana Strike on him, but that is also useless. Then the rangers use the Samurai Battle Cannon on him, whick finally destroyed him.
