Ultraman Mebius

Alien Serpents were aliens whom had come to Earth under orders of Alien Empera to destroy GUYS. Taking the body of GUYS lunch lady, Hinode Sayuri (who was hit by a car while saving the life of a child), Alien Serpent used her body in order to retrieve a portal device from her home planet to facilitate their assault on Earth. Once Hinode found out about their plan, Alien Serpent took total control of her body and managed to shut down the power to the GUYS base power plant. He then used the portal device to bring several more of his kind to Earth in order to help him in their plan to conquer Earth. Suddenly, Hinode's memories returned to her and her consciousness swiftly overpowered Alien Serpent's control, allowing Hinode to take out most of Alien Serpent's fleet with ease. Once GUYS was able to enter the fray to assist her, the remaining Serpent aliens transformed their bodies into liquid and merged to form their larger form outside of the GUYS HQ.

Now that their problem was much larger, Mirai transformed into Ultraman Mebius in order to face the giant alien. The battle quickly went in favor of the giant Alien Serpent due to its newly crafted armor, which gave him protection from Mebius's Mebium Blade. After Hinode revealed Alien Serpent's weakness to salt, GUYS used a fire extinguishing missile to completely dry out Alien Serpent's body until it was transformed into a rusty statue. Mebius then took the opportunity to destroy the statue with the Mebium Blade, ending Alien Serpent's threat. Afterwards, Hinode resumed her lifestyle as a mother, but in a comedic twist, she was now enhanced with Serpent's leftover powers.
