Alien Empera

 Alien Empera (エンペラ星人,Enpera Seijin) is the main antagonist of Ultraman Mebius. Alien Emperor is known as the King of Darkness. He comes from a world where darkness rules over all, where there is nothing but stillness. He is the master of the aliens: Mephilas, Glozam, Deathrem and Yapool, who were later revealed to be just sacrificial pawns used for his own selfishness. Alien Empera appeared in the final 3 episodes of the Ultraman Mebius series (episodes 47-50). Alien Empera, as well as his creation, Armored Darkness are among the most powerful foes in the Ultra series. Alien Empera is the strongest seijin to ever come to Earth, and the latest yet. Empera is sometimes called "Alien Emperor" or "Emperorian".

Ultraman Taro
Although not physically seen in the series, Alien Empera's story and character was first mentioned in episode 25 of the series,Ultraman Taro.

Almost thirty thousand years before any of Ultra Brothers went to Earth, Alien Empera led an army of monsters to take over the Land of Light in Nebula M78, the home of the Ultras, and temporarily succeeded in doing so. However, the Ultras soon fought back, and destroyed many of his legions, like Yapool, and managed to repel his army of monsters. This event, now called the Great Ultra War, ended when Alien Empera dueled with  Father of Ultra. Although the battle ended in a tie, both combatants received a matching scar on their hips that have reminded them both of their intensive battle from the past. However the emperor's wound forced him to retreat and he was not seen until the end of Ultraman Mebius' tour of duty on Earth

Ultraman Mebius- Episodes 1-47
The Emporor's return was heralded when Bogal began reviving summoning many monster to Earth, like Twin Tail. Following Bogal's destruction at the hands of Ultraman Hikari and Ultraman Mebius, other Bogals, known as "Lesser Bogals," opened an Ultra Zone, a gate way to the Monster Graveyard. With the Ultra Zone opened, Alien Empera slowly began a reviving process and hid his existence by creating using gigantic robot, Imperializer. However while Imperializer's strength was more than what Mebius could handle, the Imperializer was felled by both Mebius and Ultraman Taro.

Alien Empera then recruited one of his top warriors, Yapool (from Ultraman Ace), to join two more generals, Glozam and Deathrem, along with a survivor from the original Ultraman series, Alien Mephilas. The four were all veterans of the great Ultra War the Emperor instigated ages ago.This coalition of Aliens would soon be known as "The Four Heavenly Kings" as their intent was destroying Mebius to serve their Empera's demands. Eventually, even the might of Yapool was no match for Ultraman Mebius, and Deathrem and Glozam soon fell after him. Mephilas, realizing that he could not rule Earth, retreated to space, but was killed by Alien Empera himself for not completing the task, setting the stage for the final battle.

The Advent of the Emperor
Alien Empera began his world domination plan by encasing the sun in rock. He also summoned a group of Imperializers to attack different regions of the Earth. At first, Ultraman Mebius was losing the battle against the Imperializers, but after the people of Earth began cheering him on, Ultraman Mebius destroyed the Imperalizers with the same attack he used to destroy Mebius Killer, the Mebium Dynamite. However, excessive usage of the attack on the Imperializers became too much for Mirai's body to handle and thus Mirai was put in critical condition.

Later, two more Imperializers appeared to wreak havoc, this time attacking GUYS HQ. GUYS managed to destroy one of the Imperializers, but was unable to destroy the second. Just as the second Imperializer was about to destroy the GUYS base, a blade slit it clean in half, destroying it completely. It was the blade of Zamusha, an alien swordsman who had unfinished business to settle with Ultraman Mebius (and Ultraman Hikari,) who had sided with GUYS so that Mebius would be his kill. Shortly afterAlien Fanton and Alien Psychokino, alien friends of GUYS appeared as well to assist them in the battle.

With his army destroyed, Alien Empera decided to take over the Earth personally. The Alien destroyed much of Tokyo and finally encasing the Earth in darkness from the coating of stone on the sun. Zamusha tried to take out the Emperor in short order, by trying to impale Alien Empera with his blade, but the Emperor's superior strength and power was far greater than Zamusha's or what the others could handle and then Alien Empera proceeded to assault Zamshua with his shock waves.

Just then, Ultraman Hikari arrived to assist in destroying Alien Empera but was blasted to the ground next to Zamusha. The two rivals decided to work together to destroy the Empera, and GUYS began striking back at Alien Empera as well, but none of their attack did not harm him. Following his assault on Zamusha and Hikari, Alien Empera turned his attention to the GUYS base, and decided to destroy it in order to kill Ultraman Mebius once and for all. Then as he fired a shock wave, Zamusha sacrificed himself and took the hit. Dying, Zamusha realized the truth of protection.

Enraged, Ultraman Hikari grabbed Zamusha's blade and actually managed to cut another scar into Alien Empera's other side. Ryu of GUYS then charged towards Alien Empera in a kamikaze dive, but his ship was seemingly destroyed by a single hit of Empera's shock wave (In reality, Ultraman Hikari had saved him and taken him as his new human host.) Ultraman Hikari then unleashed his Hikari Blade, but was unable to even hit Empera, as the alien blasted him back with shock waves. At that critical moment, Mirai transformed into Ultraman Mebius. Hikari and Mebius combined their Hikari Shot and Mebium Shoot, but the Empera simply neutralized the new beam with his cloak.

Alien Empera decided to become offensive, and struck Hikari with another shock wave, knocking him to the ground. Alien Empera then struck Mebius with his signature move, the Dark Beam. Then after one shot, successfully destroyed Mebius. All seemed lost, but little did the Empera know that killing Mebius was the beginning of his end.

Death
Meanwhile in space, the Ultra Brothers (Ultraman, Ultra Seven, Jack, Ace, Taro, Leo, Astra, and 80) were all at work, destroying the rock that was coating the sun with their signature beams. They telepathically communicated with the GUYS team members, encouraging them not to give up hope.

Meanwhile, Mirai was revived as a spiritual entity that merged with all the other members of Team GUYS as well as Ultraman Hikari, to which gave birth to a new form of Ultraman Mebius Phoenix Brave Mode. Alien Empera's powers were now futile as they were all deflected back at him by Mebius' new form. At that moment, GUYS' final METEOR, an energy-amplifier named "Specium Redoublizer" descended from the skies.

Mebius fired a Mebium-Knight shot through the amplifier, severely weakening and wounding Alien Empera, whom was withering in agony as scale after scale was being ripped apart from his body. Meanwhile the captain of GUYS, Shingo Sakomizu suddenly merged with another Ultra that came onto the scene, Zoffy. Zoffy joined the battle, firing his M87 beam through the amplifier, and linking it with Mebius's beam. With Alien Emperor still not destroyed, Mebius performed a final technique, the Mebium-Knight Dynamite. The technique was so powerful it destroyed the amplifier and fatally wounded Alien Empera.

As he was dying, Alien Empera finally recognized that it was the bond between the humans and the Ultramen that enabled Mebius to defeat him, realized the futility of his actions, and slowly transformed into light before dissipating.

Ultraman Mebius Side Story: Ghost Rebirth
Although not seen in full body, Alien Empera's cape, boots and gauntlets were seen worn by Mecha-Zamusha. The newly reunited Four Heavenly Kings tried to resurrect the Emperor by merging Mecha-Zamusha and the Giga Battle Nizer. However, their efforts were prevented and the Four Heavenly Kings were destroyed. The Giga Battle Nizer was then lost in space after the battle and Mecha Zamusha sacrificed himself to prevent Alien Empera from ever returning again.

Trivia

 * Despite being "new" to the Mebius series, Alien Empera had actually been mentioned before during the syndication of Ultraman Taro.
 * The monsters in Alien Empera's depiction in Ultraman Taro (pictured above) include Gandar, Sartan, Bemstar, Eleking, Jamila, Terochilus, Sadora, Snowgon, Varricane, Dancan and Black King
 * Even though he was an evil alien, it seemed he died in peace (because he finally understood the meaning of light) as his body disintegrated into particles of light.
 * Despite being one of the top three most powerful known dark forces in the Showa Universe (With Belial and Alien Reiblood) Alien Empera doesn't seem to have problems when it comes to recuperating. Ultra Father received a matching wound to his but Ultraman Ken was not forced to recuperate for Thirty thousand years. Also it is much easier to revive the Four Heavenly Kings while preparations had to made before hand for the Emperor to be revived.
