Ultraman Wiki

"I only wanted the heart of the Earth. But, I have lost. I even lost to a child."

―Alien Mefilas to Ultraman, "The Forbidden Words"

Alien Mefilas (メフィラス星人, Mefirasu Seijin) is a race of recurring aliens in the Ultraman Series that originate from Planet Mefilas. The original made his debut in the TV episode "The Forbidden Words" in 1966. Alien Mefilas was meant to appear as foil to the original Ultraman, who believed in the inherent good of humanity, while Alien Mefilas believed humanity were easy to manipulate and thus set in motion to use his intelligence to subjugate humanity and take over the Earth without violence. As part of his plan, Mefilas aimed to trick the humans into giving him the Earth in a trade for another planet.

As a result of the original Alien Mefilas' insidious and distinctive means of invasion, his kind have become one of Ultraman's more memorable and personal foes, with numerous individuals of the species appearing throughout the Ultraman Series.


  • Original: Malicious Alien (悪質宇星人, Akushitsu Uchūjin)
  • Shin:
    • Extraterrestrial No.0 (外星人第0号, Gaiseijin Dai Zero-gō)
    • Ambassador Extraordinary[1] (特命全権大使, Tokumeizenken Taishi)



Alien Mefilas' name comes from "'Mephistopheles", the demon who made a deal with the titular character of the classic German legend "Faust".


Tohl Narita designed the look of Alien Mefilas to contrast Ultraman's heroic red and silver color scheme, by being mostly black with silver only being used to accentuate his face. Narita wanted Alien Mefilas to appear as a non threatening alien compared to the more monstrous kaiju and alien that had appeared before.[2]



"I detest violence. On my planet, a gentleman is courteous. To take the Earth by force would be against my principles. So I was hoping for permission from you, an Earthling. You are a wonderful Earthling, Satoru-kun. How about it? Will you say the words, "I will give you the Earth"?"

―Alien Mefilas to Satoru

Alien Mefilas in Ultraman

Alien Mefilas, much like most other aliens of the show, came to Earth to conquer it. Unlike his fellow aliens before him, however, his motive was simply to show off his abilities to the rest of the aliens who had tried to conquer the Earth themselves, such as Kemur and Alien Zarab.

Alien Mefilas's plan was to have a child of the Earth give him the Earth willingly in return for a new star. Hiding in a forest inside his ship, Alien Mefilas spied Shin Hayata, Akiko Fuji, and Akiko's younger brother, Satoru, watching an air show. Alien Mefilas spoke to Satoru, telling him to pay close attention, and then made the air show vanish into the clouds. Hayata and Fuji where baffled, but Satoru was still listening to Alien Mefilas. The alien then put a freighter vessel in place of the air show, then destroyed it in midair. Satoru then told Hayata that someone was talking to him, but before Hayata could do anything, Alien Mefilas captured all three of them.

Alien Mefilas turned Fuji into a giant and placed her in the middle of a city, and tried to convince Satoru to give him the Earth in return for a star, explaining that he wanted to "challenge the heart of an Earthling". But Satoru refused to give Alien Mefilas the Earth. Annoyed, Alien Mefilas put Satoru in his anti-gravity room. Witnessing the man of Mefilas's failure, Hayata (Ultraman) burst out laughing at him. Insulted, Alien Mefilas demanded to know what was so funny, to which Hayata replied that he couldn't convince a child to give up his planet in exchange for a new one because it was inhuman. Alien Mefilas then asked "Ultraman" whether he was an alien or a man. Ultraman simply said "I'm both", he then reached for the Beta Capsule, but Alien Mefilas froze him where he stood.

Alien Mefilas asked Satoru again if he would give him the Earth, but Satoru wouldn't answer. Enraged, Alien Mefilas made the giant Fuji go on a rampage in the city. The SSSP, who had arrived earlier, tried to keep the police from hurting Fuji. Alien Mefilas then made his presence known to them and took away Fuji and replaced her with projections of Alien Baltan, Kemur, and Alien Zarab. Captain Mura demanded that Alien Mefilas show himself, but the alien said he could see them and said he wanted the hearts of the Earth. The SSSP asked what he meant, but heard him arguing with Satoru, who still refused to give into the alien's wishes. Alien Mefilas then turned off his illusions and left the SSSP dumbfounded. However, the conversation gave the SSSP the time they needed to locate Mefilas's spaceship, and an air strike was sent.

With his ship under attack and again with no other option, Alien Mefilas seemed to escape and leave his ship behind, while the Science Patrol rescued Fuji and Satoru. Although they could not rescue Hayata in time, Hayata managed to transform into Ultraman to face off against Alien Mefilas, who emerged from his destroyed ship as a giant. Ultraman offered him a choice to either leave the planet or die like the other aliens. Alien Mefilas refused to leave and went head-to-head with Ultraman in a very evenly matched battle, as all of Alien Mefilas's attacks were strong enough to counter Ultraman's attacks and his physical strength was on par with the hero's. Then shockingly, in the middle of the fight, Alien Mefilas surrendered, seeing no point in continuing. However, before leaving, he promised to Ultraman that they would meet again and he would get his revenge in the future. The Forbidden Words

  • Similar to Ultraman's lift off shout "Shuwatch!", Alien Mefilas has his own, "Fuwa! (フワッ)".
  • It is unknown how the spirit of the first Mefilas was used to create Grand King. He may have died sometime after he had left Earth or it could have possibly been the soul of the second Mefilas who (at the time) had recently been killed by Ultraman Taro.
  • Originally, Alien Mefilas was to team up with Alien Baltan, Alien Zarab, and Kemur in a great invasion, and use Zetton and Saigo to defeat Ultraman.
  • His ship is an upside down Alien Baltan ship, which was reused from Cicada Human's spaceship.
  • The original plan for Alien Mefilas and his allies has been realised in some stage shows with Kemur, Alien Zarab and Alien Baltan II working for Meflias. Keronia has also been included instead of Dada.

Alien Mefilas II

Another Alien Mefilas appeared in episode 27 of the series, Ultraman Taro, as Alien Mefilas Ⅱ (メフィラス星人二代目, Mefirasu Seijin Nidaime).

After the first Alien Mefilas left Earth in Ultraman's time to find a new colony for his species, another member sought to dominate Earth. This Alien Mefilas tried to use a highly advanced bio-weapon called the Mandarin Grass to slowly kill off humans one by one. However after it was destroyed by ZAT, Alien Mefilas revealed himself, and suffers a major injury to his left eye from ZAT's weaponry. He then picks up the Mandarin grass, and wipes it over his damaged eye, restoring it. The second Alien Mefilas now prepared to take matters into his own hands by attacking ZAT directly. Before the situation could get worse, Kotaro turned into Ultraman Taro to do battle. Alien Mefilas was easily tossed around by Taro and after the hero punched a hole through his body, Taro used the Strium Ray, reducing Alien Mefilas into slime, therefore killing it. There He Is! Alien Mefilas!


  • Voice actor: Ikuo Nishikawa (uncredited)
  • This Alien Mefilas is very differently redesigned from the original Alien Mefilas's appearance. This Alien Mefilas 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 bulkier appearance of the original Alien Mefilas.
    • His original design was meant to be a copy of his original design only with the red lining around his eyes. The previously mentioned design above was only as such due to the budget restricting the company to use a modified cheaper suit that was used for attractions.
  • Originally the mushroom monster, Mushra was suppose to appear in Alien Mefilas's episode, but was pushed back for a later episode.
  • In Ultraman Story it is said that he is the original and that he was the one in control of Re-Eleking despite appearing and being killed in the episode right before Re-Eleking's appearance.
  • Many magazines at the time stated this Alien Mefilas is the younger brother of the original who sought Earth whilst his brother was busy managing an unseen monster army.
  • Alien Mefilas II was one of the many monsters that comprised Belyudra's body.

Ultraman Story

Alien Mefilas appeared again in the 1984 movie, Ultraman Story. He is only shown as stock footage from Ultraman Taro and is the original Alien Meflias from Ultraman as stated in the movie.

After his Re-Eleking was defeated by Ultraman Taro, he decided to attack Earth himself. Father of Ultra hears about this and quickly trains Taro to fight of Alien Mefilas' comeback. Once Taro was ready, he headed to Earth and defeated Alien Mefilas only to see there was a bigger threat.


  • Although claimed as the first Mefilas that the original Ultraman fought, ironically his scene and defeat reuses the footage from Generation II's. If the movie is canon, then the story itself had concluded the alien's fate after retreating from a fight against his rival Ultraman.

Armored Mefilas

Alien Mefilas appeared in episodes 9, 12, and 13 of the series, Ultra Galaxy Mega Monster Battle: Never Ending Odyssey.

In this series, an Alien Mefilas is a Reionics who once wielded a Battlenizer until he was defeated and left for dead by an Alien Temperor prior to certain events in the show. After discovering Armored Darkness's Darkness Broad sword, Mefilas is transformed into Armored Mefilas (アーマードメフィラス, Āmādo Mefirasu) and thus goes on a killing spree for those who mock him or get in his way, all while being controlled by Armored Darkness's conscience. He kills a Dada that mocked him earlier, and attacks Reimon for standing in his way. He later confronts the Alien Temperor that defeated him earlier for a rematch and winds up killing both and his monster, Arigera. Shortly afterwards, Armored Mefilas revives Armored Darkness to serve "his master", only for Armored Darkness to kill Mefilas and retrieve the sword he had taken away. Armour of Darkness

During the series finale, Armored Mefilas was revived as a giant-sized and mindless slave being controlled by Alien Reiblood. After facing off against Rei's monsters (Gomora and Miclas), Alien Mefilas is eventually freed from both Reiblood's control and the Armor that possessing him. After being transformed back into his normal form, Alien Mefilas frees the Pendragon from an inter-dimensional rift underground created by Reiblood to keep them from contacting Rei out of gratitude to Rei for saving him.

A cameraman for NPTV's documentary program, Mefilas's section was failing and views were dwindling. Their boss, an Alien Chibull, warned them that if things don't change, they will have to face some consequences. Mefilas then got the idea to have his partner Alien Zarab to disguise as a giant Saki Mitsurugi, but their director reprimanded them. They then went around interviewing other people and aliens regarding their thoughts on Saki's plan to turn Earth into a bomb, but yet again the director said that if they don't get the views, the sponsors would pull out and the program would be cancelled. Desperate for a solution, they decide to interview Ushio Minato, who they saw potential in after seeing him on the news. The two then took on human disguises and went to Quattro M to interview him, and disguised as a man named Suzuki (鈴木) to do so.

After the interview was over, they went over to Aizen Tech to interview Saki Mitsurugi regarding her plan, asking if she could hurry it up, even though they didn't have much hope that the interview would go well. However, the duo were chased out. They then went back to interviewing other people, this time about Ushio. Coming to the conclusion that an Ultraman's father would have extraordinary abilities, Mefilas decided to set Ushio up. He had Zarab disguise as Asahi Minato and restrained near a bomb and lots of explosives, in a life-or-death game that he thought would really get him the views he needed and was even willing to sacrifice the Zarab, who was unaware that the explosives were real. Katsumi Minato and Isami Minato found out about the plot, and transformed into Ultraman Rosso and Ultraman Blu and after the battle, Mefilas was destroyed by the Triple Origium Beam and Zarab was set free by Ushio. A World Without Tomorrow

Shin Ultraman

"Above all, I desire this beautiful planet to myself. I, too, love the human race, Ultraman."

―Mefilas to Kaminaga (Ultraman)

Mefilas was seemingly the third alien to appear Planet Earth after Zarab and Ultraman. According to him, however, he was infact the first alien on Earth. He had been keeping an eye on the Earth for a while, orchestrating all of the Kaiju-related events thus far. He first made his presence known when he used his Beta Box, a less advance version of the Beta Capsule that the beings of the Planet of Light use. He would demonstrate its power by enlarging the hypnotized SSSP member Hiroko Asami. He allowed the humans to attempt to experiment on her only to find nothing of use because of the invulnerability the Beta System conferred upon Asami.

At night, Mefilas showed himself to the SSSP and introduced himself as Extraterrestrial #0, since he had arrived before Ultraman did. When asked to prove that he was an alien, he showed them the Beta Box, and reverted Asami back to normal. Mefilas then met with members of the government and offered to provide them with Beta Boxes as the ultimate defensive measure against other Kaiju and hostile aliens, to which the government was swiftly swayed. However, the other end of the deal was that Mefilas now essentially owned the planet.

Mefilas then met with Shinji Kaminaga, knowing that he was Ultraman, at a park where he told Kaminaga about his true intentions, confident that Ultraman could do nothing to stop his plans to make use of the Earth's seven billion humans as weapons via the Beta Box: first he awakened the leftover biological weapons (Kaiju) on the planet and passed it off as acts of nature caused by reckless human development. He then used the next-generation biological weapons (Neronga and Gabora) to lure out Ultraman, hoping that he would fuse with a human so that it could prove that the Beta System was compatible with humans. Then he used Zarab's appearance to instill fear of extraterrestrial threats on humans. Finally, he used his demonstration of the Beta System on Asami to make humans feel both intellectually and physically impotent, ensuring their subordination to extraterrestrials. Their conversation was interrupted by armed personnel who intended to surround Kaminaga and take him into custody because of Zarab exposing his identity as Ultraman, but Mefilas did not want any interruptions and teleported both himself and Kaminaga to a bar to continue their conversation.

It seemed that Mefilas' plan was perfect and unstoppable, Ultraman could do nothing but incriminate him because according to space laws and the Code of the Planet of Light Ultraman could not interfere with the decisions of humans, which Mefilas had already sealed via contract with the government. Ultraman disagreed, saying that the Code does not apply to the human he had bonded with, and would use Kaminaga's will to stop Mefilas even by force.

"This is pointless, Ultraman. Unfortunately, I'll have to step aside here - this planet is no longer worth killing you over. I will take the Beta Box with me as you requested. [He takes the Beta Box] Received and accepted. There's a complication afoot. I should leave before things get unpleasant. Farewell, Ultraman."

―Mefilas's last words to Ultraman before he left Earth.

Just as the Beta Box handover was about to commence, Ultraman's hand came through the Planck Brane Dimension and grabbed the Beta Box, throwing it into a helicopter that the SSSP prepared. Mefilas used the device to enlarge himself remotely, preparing to fight against Ultraman. Due to the burden of fusing with Kaminaga and the enlargement via the Beta System, Ultraman's reserves of Spacium 133 were depleting quickly, and almost lost in a beam clash against Mefilas. Their fight came to an abrupt end when Mefilas noticed someone watching in the distance. Realising that he faced certain death at the hands of this newcomer, Mefilas informed Ultraman that he no longer believed the Earth was worth killing him over. The SSSP gave Ultraman the Beta Box, and he immediately handed it over to Mefilas, who agreed to take it with him as he had been requested. Informing Ultraman that there was 'a complication' afoot, he bid the Ultra farewell before teleporting away, leaving Earth on good terms.Shin Ultraman
