Alien Icarus's History
Alien Icarus are bat-like aliens from the Fourth Dimension that debuted in Ultraseven.
The Icarus aliens were an advanced race. They planned to invade Earth using the 4th dimension. A man (Icarus) was the neighbor of a young boy. The young boy knew he was an alien. Nobody believed him until they saw a bird floating in the air that was not moving or falling. Dan Moroboshi aka Ultraseven, came to investigate. When he jumped out a window, Dan was in a dimension with yellow balloons where the neighbor revealed that he was an Icarus. He planned to take over Earth with his giant size and saucer. He then ordered his saucer to attack an oil district. Dan realized he could not use his capsule monsters or transform, though he knew that he had to destroy the alien device. Dan was now in a forest along with the alien man. The alien man became a towering Icarus and Dan became Ultraseven. Now the fight began with Icarus trying to attack but, Ultraseven dodged. Icarus' ship attacked but, Ultraseven hid behind a mountain. Icarus and the saucer had him pinned down until, the UG attacked the ship. Icarus began to shoot his energy rays, but Ultraseven managed to dodge and kick Icarus high into the air. Ultraseven threw the eye slugger at him, greatly injuring Icarus. Ultraseven tossed Icarus over the mountain, via telepathy. Icarus' saucer tried to retreat but was shot down.
Alien Icarus was a combatant of the Dark Spark War who was then turned into a Spark Doll by Dark Lugiel. Lugiel then Darklived him in the special so that he can be the successor to Alien Valky as Lugiel's servant. He was first seen to Hikaru Raido and his friends in the woods, while they were looking for the Spark Dolls that combine to form Tyrant, in front of Misuzu Isurugi and Kenta Watarai holding King Crab's Spark Doll. He refused to hand it over at first, but after a combination of Tomoya Ichijouji's Gunpad, Kenta's camera flash, and Ultraman Taro's Ultra Psychokinesis, he was sent flying. Icarus was then seen scheming after Hikaru Raido and Chigusa Kuno left with Bemstar in Icarus' right hand and Seagorath in his left. He disguised himself as Misuzu to trick Hikaru into handing over the Spark Dolls but the Ginga Spark dispells his disguise and he chases after the group. Icarus then takes Misuzu hostage and steals the rest of the Spark Dolls (Hanzagiran, King Crab, Red King, and Baraba) so that he can Darklive himself and the other Spark Dolls to form Tyrant. After Tyrant was defeated by Hikaru as Ultraman Tiga and Tomoya as Jean-Nine, the monsters were turned back into Spark Dolls while Alien Icarus became his alive self again. Hikaru and his friends then tied up Icarus and demanded Icarus to tell him who his master is. After a few shots to soften him up, Icarus was about to confess his master's name, until Lugiel shot him in the back and reverted him to a Spark Doll.
Alien Icarus returned serving as one of the hosts along with all of Dark Lugiel's former agents, Valky and Nackle Gray.
His appearence in Ultraseven was referenced by the titular Ultra's son and his fiery friend. What they did not realize was that Alien Icarus was actually watching them talk on TV with a Dark Dummy Spark in his hand. He then cursed Ultraseven, his son, and his son's friend for the wound on his chest that was inflicted by Ultraseven's Eye Slugger. In episode 12, he was seen sneaking up on Hikaru Raido and Ultraman Taro as they talk about Tyrant and all of the monsters that make up the chimera. When Ultraman Taro, could not remember the monster that makes up Tyrant's ears, the fiend shouts out loud and then his cover was blown. He later attempted to host the episode and talk about the rest of the monsters that make up Tyrant but after a beatdown by Hikaru, he teleported away to safety.
He reappeared later, where he met up with Alien Valky and Alien Nackle Gray on a desert planet after they were sucked into a wormhole. They then talked about Mega Monster Rush Ultra Frontier, the Rush Hunters team, and the monsters they fought. At one point, Icarus became really upset after hearing about how Ultraseven defeated Dinosaur Tank because he was the same guy who kicked his butt at his time. When they were done, they realize they can't get out of here and curse Ultraman Ginga.
Alien Valky and Alien Nackle Gray were floating in space while commenting on their master's defeat. Alien Icarus showed up and brought them to his self-created pocket dimension where he revealed them to be future characters in Ultraman Ginga S as well as the new villains Alien Chibull Exceller, Android One Zero, Alien Guts Vorst, and Chiburoids all by his retro television. With the episode coming to an end, they found a black hole and race themselves inside to return to Ginga's universe to watch the battle.
Alien Icarus was Darklived along with Alien Valky and Alien Nackle Gray joined forces with Alien Zetton Berume and the remaining Chiburoids, calling their team as Dark Lugiel Rangers to stop Hikaru, Sho, UPG, and the Victorians from stopping Dark Lugiel's plan. He went up against Tomoya Ichijouji after the latter took down a couple of Chiburoids. Icarus tried to attack, but Tomoya hit him on the head hard and the alien fell down as a result. Tomoya then fired his Gunpad at a couple of Chiburoids. It can be assumed that Icarus was wiped out by the explosion that happened after Tomoya shot down the Chiburoids.
He appears with the other two revealing that they survived the final battle but have to work as janitors for the UPG. In his free time, Alien Icarus invented the Icarus Pad to hack into UPG's Kaiju Database and take a look at Etelgar and all of those serving as his Eteldummies. One time, Icarus used the pad to summon a hallucination of the same girl who kicked his butt as a joke for offending Etelgar. After he brought it back, Valky became furious at him, but he calmed down later. Icarus used the pad to look up Five King because he remembered when he Darklived himself into Tyrant, but after Icarus revealed more minions, he fought with the others until Nackle Gray noticed Ultraman Victory's new form. After an alarm, Captain Yoshiaki Jinno appeared, busted them, and threatened them to get back to work.
Icarus, along with the other two aliens and the two UPG members, visited headquarters to celebrate the 100th episode of New Ultraman Retsuden. He then took a look at Kaiser Belial and his army via the Kaiju Database. Near the end of his section, they were going to watch Ultraman Victory in Ultra Fight Victory but they were ordered by Gouki to get back to work, which both surprised and upset-ed the aliens.
Another Alien Icarus would appear in Ultraman X. Long ago, an Alien Icarus named Icary befriended two other aliens, Nackley and Haruki. Settling their rent home on Earth, the Nebula House, they disguised and worked in a human society. Icary disguised himself as a human named Ikari, a convenient store worker. Wanting a new housemate to ease their monthly rent of 15,000 yen, they find Isamu and accepted him.
Learning that Isamu was a former rugby player, they counsel his problems and one day, after the appearance of Halky's Samekujira accidentally attracted the Dark Star Cluster's attention, they challenge the thieves in a rugby match. After three days of training, the Nebula House residents manage to win the match. They thank Isamu for his help and allow him to rejoin his rugby team.
In Ultraman Decker, one of Gibellus' henchmen, Alien Icarus, was summoned after the latter had taken a large number of Japanese citizens' souls with the white orb object. Asumi and Dinas were dispatched to go after the alien while Kirino and Ryumon followed them with GUTS Falcon and Hawk. Asumi and Dinas chased Icarus down the street. However, he teleported above them and summoned two crystal-like devices that created a subspace field, trapping the GUTS-Select team inside with Falcon and Hawk stuck on floating rocks. Icarus appeared before Asumi and Dinas, with Dinas later transformed into Ultraman Dinas to fight the alien. The battle was rather thoughtful as Icarus gained the upper hand. Dinas used Eleking's Mons Dimension Card power, but Icarus quickly teleported behind him and fired an Arrow Beam into him. Icarus continues to beat Dinas. On the other hand, Kirino succeeded in destroying one of the devices, which weakened the field and freed both Falcon and Hawk. A doppelgänger of Icarus was chasing after Asumi. Fortunately, the mechs combined into GUTS Gryphon and fired the Hyper Thorn Laser toward the alien, destroying him while carrying Asumi. Dinas still struggled hard enough against the real Icarus, but Gryphon briefly aided Dinas to give an opening chance for the Ultra. Dinas later utilized both Zetton and Kelbim’s cards to perform a flame-induced heel drop attack on Icarus and killed him while at the same time, Asumi destroyed the last device, freeing all of them from the subspace field.
