Character History


In his original debut, Alien Mefilas was an alien who had come to Earth with the intentions of conquering the planet. However, Mefilas was rather different from the Aliens before him, as after he kidnapped Hayata and Fuji of the Science Patrol, and Fuji's younger brother Satoru, his first means of capturing the planet was by simply asking Satoru to give it to him, stating that he did not like violence, and in exchange, he would send Satoru to a Planet far greater in life expectancy and riches than that of Earth. However, Satoru refused the Alien's offer, firmly stating that the Earth was his home. Not tolerating stubbornness either, Alien Mefilas locked Satoru away and using the power on his ship, he had placed Fuji under his control and ballooned her to enormous proportions, sending her to attack Tokyo as a warning to the people of Earth of what he was capable of. Fuji managed to do some damage in her temporary giant form, but was fended off by the Defense Force, causing Mefilas to swap her out with other aliens at his disposal. The likes of which include Alien Baltan, Alien Zarab, and a Kemur Man, again warning the people of Earth what awaited them if they did not comply with his wishes.

Despite the Alien's menacing-looking powers, the Defense Force and the Science Patrol firmly refused his demands as well, and after finding his invisible ship in the middle of the Takinezawa Mountains, they bombarded his ship with their weapons. Mefilas was able to fend off the opposition from the Defense Force, but not against the Science Patrol, who managed to hold up better and managed to send Mefilas into fleeing from his ship while the team managed to break in and rescue both Fuji and Satoru. Meanwhile, Hayata (who was frozen in place earlier by the Alien before he could stop him within his ship.) was left behind as the team didn't have enough time to save him, but luckily, he accidentally fell over, and the impact caused him to transform into Ultraman! Alien Mefilas (now having taken on a giant form) prepared to attack the Science Patrol, but was confronted by Ultraman, who ordered him to leave Earth. The alien refused, and so Ultraman and Alien Mefilas engaged in a fierce battle, with neither side able to best the other.

Finally after an evenly-fought battle, Alien Mefilas admitted defeat, relenting that his plan had already been foiled and that all he really wanted was the emotions of humanity. However before he teleported away, he ominously warned Ultraman that one day he would return and someone would give up the Earth to him when he did...

Ultra Galaxy Mega Monster Battle: Never Ending Odyssey

Alien Mefilas reappeared in the series, Ultra Galaxy Mega Monster Battle: Never Ending Odyssey.[2]

In this series, Alien Mefilas was one of the many Reibloods who were battling on Planet Hammer for supremacy. Prior to his appearance however, the Alien was defeated in battle by a Reiblood Alien Temperor and was left to aimlessly wander the Desert in shame. While wandering, the Alien Mefilas noticed a giant Sword embedded into the ground. Going in to get a closer look and placing his hand on it, Alien Mefilas suddenly witnessed a fierce battle between two beings, one humanoid and the other covered in armor, both of whom are fighting in a land surrounded by fire. As Alien Mefilas sees the vision unfold, a dark light on the Sword comes on and the sword activates by flying up and landing back down into Mefilas's hand, now smaller in size. Then as if being controlled by the Sword, Alien Mefilas transforms into "Armored Mefilas!" Armor of Darkness

Alien Mefilas's last appearance was during the series finale, where he was freed by Rei after Reionic Burst Gomora destroyed him in his Armored State. Returned back to normal, Alien Mefilas noticed the revived and possessed Armored Darkness and realizing that Alien Reiblood and Armored Darkness used him as a puppet to do their bidding, Alien Mefilas decided to get even with them by teleporting to the void where the ZAP SPACY's Pendragon was still stuck, unable to escape from the energy field they were trapped in. Alien Mefilas then freed the ZAP SPACY with his own energy to allow them to help Rei, stating that he owed Rei for freeing him before teleporting away. Planet Destruction
