Alien Mephilas, much like the other aliens of the show came to Earth to conquer it. Unlike his fellow aliens before him, his intentions for control over the Earth was not by mass extinction of the humans but merely to save his species from dying on his original home planet. With no other option however, Mephilas had to conquer the planet in order to save his species.
Hiding in a forest inside his ship, Alien Mephilas's main source of conquest over the planet was to use illusions to trick or fool the humans into believing he had greater power than he actually does, from lifting boats and planes telepathically, to "reviving" monsters whom had died in the past (ex. Alien Baltan, Alien Zarab, and Kemur.) He used these illusions against the humans as threats that if they did not surrender in time he would unleash his "power" upon the Earth. During which, Mephilas had taken both a young boy whom had spied on him, Fuji the female member of the Science Patrol, and Hayata (the human host of Ultraman) as his hostages, fully intent on forcing the earth to surrender. Eventually, the Science Patrol and the military found his ship and attacked him.
With his ship under attack and again with no other option, Alien Mephilas turned into a giant and faced off against the military while the Science Patrol rescued Fuji and the boy. Although they could not rescue Hayata in time, Hayata manages to transform into Ultraman to face off against Mephilas and offered him to leave the planet or die like the other aliens. Mephilas chose to fight and both Ultraman and Mephilas went head-to-head in a very, evenly-matched battle as all of Mephilas's attacks were strong enough to counter Ultraman's attacks and his physical strength was on par with Ultraman's. Then shockingly in the middle of the fight, Alien Mephilas surrendered realizing that if he died he could no longer save, nor protect his home planet and thus left peacefully. However before leaving, he promised to Ultraman that they would meet again and he would get his revenge in the future.
Trivia
Unlike most aliens in the series', Mephilas's reason for invasion is rather tragic due to his species being endangered. Therefore, he is one of a few aliens whose more anti-heroic rather than evil.
Mephilas was supposed to conjure up an illusion of Dada as well, but this plot point was dropped for unknown reasons.
Mephilas's voice actor is Seizō Katō, who is famous for his role as Megatron and Galvatron in the japanese dub of the original Transformers series.
Mephilas's design and name originates from the German book "Mephistopheles".
An Alien Mephilas appeared in episode 27 of the series Ultraman Taro, as Alien Mephilas II.
After the first Alien Mephilas left Earth in Ultraman's time to find a new colony for his species, another member sought to dominate Earth and succeed where the original had failed. This Mephilas tried to use a highly advanced bio-weapon called the Mandarin Flower to slowly kill off humans one by one. However after it was destroyed by ZAT, Mephilas revealed himself and decided to take matters into his own hands. Before the situation could get worse, Kotaro turned into Ultraman Taro to do battle. Mephilas was easily tossed around by Taro and after the hero punched a hole through his body, Taro used the Storium Ray, reducing Mephilas into slime, therefore killing it.
Trivia
This Mephilas is very differently redesigned from the original Mephilas's appearance. This Mephilas had a golden-colored hip and his neck was stretched out more to make him look taller. The white color around his eyes were dark pink and the lights in his "mouth" moved in a triangular motion when he spoke rather than a vertical motion like the original. His body is also more slender than the more bulkier appearance of the original Mephilas.
Originally the mushroom monster, Mushra was suppose to appear in Mephilas's episode appearance, but was pushed back for a later episode.
Due to this being a different Mephilas it does not have the the same powers it's only power is blue eye lasers.
Alien Mephilas II is also one of Beryudora's body part.
Alien Mephilas reappeared in episodes 43 through 47 of the series, Ultraman Mebius. In this series, Alien Mephilas has formed an alliance with Yapool, Deathrem, and Glozam to create "The Four Heavenly Kings." A Coalition of aliens that serve a higher up entity who they know simply as "The Emperor".
After Yapool, Deathrem, and Glozam were all defeated, Alien Mephilas comes to Japan in a new ship and this time he uses mind control on the populace to turn them all, as well as Team GUYS against Ultraman Mebius. He further panders to the people of Japan by demonstrating his power to destroy a Gromite he creates only to destroy shortly after out of false heroism and accolade. All the while, the original Ultraman returns to confront Mephilas into stopping him from doing any harm to the humans. However seeing as Mephilas has not harmed any humans, Ultraman cannot fight him. Eventually Ultraman Mebius (as Mirai) manages to show Team GUYS the control that Mephilas has put them under, Mephilas tries to attack them out of self-defense and shortly afterwards appears himself to battle Mebius. Ultraman shows up and both Ultraman and Ultraman Mebius shortly double-team Mephilas. After shrugging off one of Mephilas's lightning attacks, Ultraman persuades Mephilas to surrender in order to save his own life knowing that he cannot beat two Ultras and Team GUYS. Once again, Mephilas wisely surrenders and even acknowledges to Team GUYS of their efforts from defeating the other three Aliens. However before leaving, he promises to Ultraman that he would return to personally challenge him again. However, the promise was shortly broken as Mephilas was then killed himself by the entity of the Emperor himself: Alien Emperor.
Trivia
This Alien Mephilas is not the original Alien Mephilas, but a third, separated from both the first Mephilas and second. Tsuburaya decided to make this character a third character after having him masquerade as the first until the April Fools Day after the episode aired.
Seizō Katō reprises his role as Mephilas's voice actor in this series, as well as his appearances in Ultra Galaxy NEO and Ghost Rebirth.
This Alien Mephilas more closely resembles the original Mephilas than any other in the many ultra series

Mega Monster Battle: Ultra Galaxy Legend The Movie
Alien Mephilas is one of the four major antagonists in this prequel to the above movie. He, along with Deathrem, Glozam, and Yapool (In the form of Mebius Killer) assault the Ultra Brothers in an attempt to reunite the Giga Battle Nizer and Zamusha (now known as Mecha-Zamu,) in an attempt to resurrect Alien Emperor. However, their plans are foiled when Ultraman Mebius looses the Giga Battle Nizer. After the Ultra's fight with Deathrem & Ace Killer, the four Ultramen surrounded the two surviving Heavenly Kings. As Glozam struggled to get up, Mephilas kicked him aside towards Mebius and Hikari. While he cursed, Mephilas fired an energy blast that killed him, saying that its for the resurrection of their Emperor. After Mebius attempted to get Mecha Zamu back with his bleeding light, Mephilas kicked Mebius aside and penetrates the Giga Battle Nizer to Mecha Zamu's chest, but only get killed by Hikari after this.
Trivia
In this entry, Mephilas is rather out-of-character. Here, he is seen as arrogant, cocky, and somewhat cowardly, as opposed to his usual composed and cunning self.
Unusually, The Armored Mephilas Suit from Ultra Galaxy NEO was reused for Mephilas's appearance in the film. This is a major continuity error as the Mephilas displayed is suppose to be the same Mephilas that served as one of the Four Heavenly Kings in Ultraman Mebius.
This was done as the Ultraman Mebius Mephilas suit was already modified into the "Armored" form, and couldn't be modified backwards due to short schedule.

Alien Mephilas reappeared in episodes 2, 17, and 18 of the variety show, Ultra Zone.

It is to note that Tsuburaya has used the Armored Mephilas suit since Ultra Galaxy Neo this maybe because they could not alter the suit or they just wanted the Armored suit instead of the normal one.
