Ultraman Dyna's History
Ultraman Dyna is the protagonist of the eponymous series Ultraman Dyna. His human host is Shin Asuka, a member of Super GUTS, whom he bonded with to fight against the Spheres and other threats to the Earth.
When Kazuma Asuka was taking part in the Zero Drive navigation test, he entered a tunnel of light. Through a strange reaction to his body in the "Light Dimension" and the technology of the Zero Drive, Asuka was transformed into a new giant of light. He then spent the years between the end of Tiga and the start of Dyna, fighting evil across space. However, upon sensing his son, Shin Asuka was about to die, he flew across space and merged with his son to save his life.
The Ultra merged with the Super GUTS rookie, Shin Asuka when the Mars Base of TPC was attacked by Spheres. The Ultra then introduced himself broadly to his later companions by destroying Darambia by just transforming. However, he would then show off his skills by defeating the newly created monster: Neo Darambia. Some of the older members of the TPC contingent in the colony believe it is Ultraman Tiga, returned and renewed. The elder officers, however, realize that it isn't Tiga, but may be another guardian like him. Asuka as the Ultraman faces Darambia and finally defeats him.
Soon, when Giralen, another monster created by the Spheres attacks the Super GUTS Base, Asuka transforms into the Ultra once again and finishes the monster with the Revolium Wave. After witnessing the whole battle, Mai, the team's operator decides to name the Ultraman as Ultraman Dyna. Later, after his fight as Dyna with Grossyna, Asuka becomes albeit mature, realizing fully his responsibilities as a Super GUTS member. Many of these monsters taught Asuka lessons and gave memories to the young-adult, who began his motto "Never give up!"
Taking place during the main series, Asuka as Dyna battles Geranda on the moon along with Super GUTS on their GUTS Eagle. Both monster and Ultra seemed evenly matched in strength and abilities, until Geranda was destroyed by a mysterious battleship.
Upon returning to Earth, the Super GUTS team were called to a secret island base stationed on Coreomoes Island (first debuted in Ultraman Tiga). Here they discover that TPC is also responsible for building the space-battleship. The ship known as Prometheus, and its devastating main weapon is the Neo-Maxima Cannon which was once used in the original GUTS' Artdessei. The project leader, Dr. Kisaragi, explains that Super GUTS has been summoned so that their brainwaves can be used to give real-battle experiences to the battle computer of Prometheus, making it an even more effective weapon. Asuka doubts that Prometheus can ever be as effective as Dyna at defending the Earth. He accepts the challenge, and enters the capsule. Before entering, Dr. Kisaragi also calls him "Dyna", provoking his awareness before his memories being uploaded into the battleship, despite Asuka's protests. There, Asuka has a vision of the ship's previous battle with Geranda and surprisingly, the ship also fires the Neo-Maxima Cannon at Dyna. Though the giant tries to repel it with his Solgent Beam, it failed thus reducing him into dust.
When Asuka regains consciousness, the base is attacked by an alien spaceship, with energy waves identical to that found from Geranda, and Asuka transforms into Ultraman Dyna to face the alien UFO. Prometheus is also launched, but to destroy Dyna, not assist him. Dr. Kisaragi announces that both she and Prometheus are under the control of the alien race known as the Monera. Prometheus, mollusionized into Deathfacer, is able to anticipate and counter all of Dyna's moves due its knowledge of the Ultra based on Asuka's brain scan result. The one-sided battle ends when the robot proceeds to fire his Neo-Maxima Cannon at Dyna, but the Ultra, having experienced the nightmare of him perishing by the giant laser managed to evade, leaving a large crater on the island. Dyna disappears and is presumed dead.
While Super GUTS regroups and finds out that they have all survived, including Asuka, however, Mai was wounded gravely for not being able to escape the base fast enough, and together with the battle caused Asuka to lose his confidence. After talking with the original GUTS leader, Captain Iruma, Asuka regains his confidence and transforms into Ultraman Dyna Strong Type. This time, Dyna is ready for Deathfacer and finally defeats Deathfacer by driving his fist through Neo-Maxima Cannon when it does 'pre-shoot charging sequence'. Dyna then throws the unstable Deathfacer into the air, before it explodes. However, the Monera fuses themselves with their spaceship to form the gigantic Queen Monera which captures Dyna and instantly devastates the city. Dyna tries to escape, and Super GUTS, as well as Captain Iruma, try to aid, but Dyna's energy is drained completely and his timer runs out, dying.
However, the brief return of Ultraman Tiga revived Dyna and both past and present heroes combined their efforts to defeat Monera. Afterwards, Tiga salutes Dyna before both of them disappear. The entire Super GUTS reunite to celebrate their victory against the monster.
Ultraman Dyna reappeared in this movie again as a main protagonist, now fighting the invading forces of the Alien Dehadoh, involving Arwon, One-Z, and others.
On Sphere's last assault on the Mars Base, Dyna would be forced to fight the thing created from his power, Zeluganoid, created by the TPC. At the final battle, Dyna and Super GUTS would defeat Gran-Sphere, but the battle also came at a high price: Asuka (as Dyna) gets himself sucked into a gap between dimensions, where Asuka would meet his father one more time as they fly to an unknown destination.
Due to Tsutomu's desire to save Gaia and to defeat King of Mons and his allies to save another universe's Earth, Tiga and Dyna appeared and teamed up with Gaia. All of this came about by a ball that granted wishes. Involved in the final battle against King of Mons. Dyna fought Bajiris and eventually destroyed it using the Empowered Solgent Beam. Along with Tiga and Gamu, they disappear out of Tsutomo's wish for the Red Sphere's non-existence.
After some time in the dimensional portal Dyna reappeared aboard the ZAP Spacy ship, the Pendragon, as it was being attacked by Alien Zetton and Nurse. After defeating both of them with little effort, he took the crew to the Monster Graveyard near Nebula M78, home of the Ultras who were like the guardians of light except for their origins being the result of evolution from their artificial sun known as the Plasma Spark. Upon arriving at the Monster Graveyard, Dyna fought Ultraman Belial and managed to hold his own until Ultraman Zero showed up to beat him mercilessly. Shortly after, Belial created the monster Belyudra, a creature composed of monsters from his own universe and several others, to fight off the heroes. Belial was on the top of its head. However, the Ultras and ZAP Spacy still fought back and through their courage and sheer tenacity destroyed Belyudra. Once the Plasma Spark was restored to its temple, the people of Nebula M78 would continue on their mission to fight evil and defend the innocent throughout the universe with Shin Asuka and Dyna becoming allies of ZAP SPACY.
In Ultraman Saga, Dyna first appeared in the city after Arstron had caused massive havoc and defeated the Kaiju instantly with the Solgent Beam. Later, Dyna transformed back into Asuka and joined forces with E.D.F., Team U and spent some time with the kids in their care, until he had to face the Gigant Zetton alone and was unable to defeat it. Thus, he turned into stone but not before expelling the Lieflasher away. He was revived when a little boy found his Lieflasher and tossed it to his color timer, and joined forces with Cosmos and Zero to combat Gigant Zetton and managed to defeat it but, then it morphed into its true form, Hyper Zetton. The three Ultras battled the Titan but with their strength they were still unable to defeat the Kaiju and reverted back to their human forms. Refusing to give up, Asuka, Musashi and Taiga combined their power to become the new giant of light, Ultraman Saga. Later Hyper Zetton created multiple monsters with multiple Spheres. All seemed lost until Ultraman, Ultraseven, Jack, Ace and Leo appeared to fight the monsters while Saga fights Hyper Zetton. The hero continued his battle with Hyper Zetton but even with the fusion, Saga was only evenly matched with his foe. With the help of Team U, the mighty Ultra destroyed the Alien Bat and his creation with the Maximum Saga. After the battle Asuka goes back to his dimension for a brief moment to inform Super GUTS that Taiga is well. He gives them a thumbs up before resuming his journey.
Prior to Ultraman Ginga, Ultraman Dyna participated in the Dark Spark War but this time he fought with the other Ultras that appeared in other series. In the midst of their battle, Dark Lugiel turned every Ultras alongside their allies, Kaiju and aliens into Spark Dolls. It was then an unknown warrior appeared and faced Dark Lugiel but like the others he also turned into a Spark Doll but he was kept within his Ginga Spark and fell alongside the other Spark Dolls to Earth. It is unknown whether Dyna was lost in the town or was kept by Dark Lugiel as part of his collection.
During his travels, Dyna presumably encountered Etelgar and was imprisoned by him. After being freed, he would fight alongside the other Heisei Ultras, in particular Tiga and Gaia, where the three would team up against Five King, a monster formed by their memories of past enemies (in Dyna's case, Reicubas). While Dyna assumed Miracle Type, all three Ultras managed to defeat the colossal beast once and for all.
Asuka as Dyna came to Orb's aid when he sensed something was off in another universe, the one where Orb was in. He first arrives and helps Orb face off against several Bezelbs and a Kugutsu-infected Birdon, using his Strong Type on screen for the first time in a long while. Dyna later appears so that he, Orb, and Cosmos can fend off the Bezelbs' attack on Planet Kanon. War Deity He stays behind on Planet Kanon to help the people recuperate after Psychi's minions retreat, and leaves them to Orb. His last appearance in the series was in the final episode, where he and the other Ultras fought Psyqueen.
