Ultraman Agul V.1
Ultraman Agul is sometimes a rival, sometimes an adversary, but eventually a teammate, of Ultraman Gaia. Dark and menacing in contrast to the red-and-silver Gaia, Agul originally showed an interest in defeating monsters that threaten the Earth, without any consideration for human lives that he may endanger in the process.
Agul's human form is Fujimiya Hiroya, a boy-genius formerly with the Alchemy Stars. Fujimiya created the giant computer known as "Crisis," able to predict future catastrophes. Its first prediction, however, showed the total destruction of the Earth. When queried further, the computer had one response: AGUL. At that moment, Fujimiya yelled in pain. In a vision, he sees a destroyed world, with a blue-and-silver giant towering over it. Through Crisis, Fujimiya discovers the cause of Earth's destruction: mankind.
Fujimiya breaks away from the Alchemy Stars, obsessed with discovering more about this being that continues to contact him, although each contact brings great pain. He builds a giant water tank, the basis of an experiment to contact "the Earth" to find out what to do. At one point, as Fujimiya stands on a catwalk above the tank, Agul contacts him again. This time, Fujimiya sees the surroundings: complete destruction, the remains of a civilization similar to Earth's! In shock, Fujimiya tries to shut down the experiment, but is convinced by his friend Kyouko to keep going. Returning to the tank, Fujimiya witnesses a great light forming at the bottom of the underwater tunnel. The light erupts from the tank, and flows into Fujimiya.
After this, Fujimiya shuns all human contact, although he still has feelings for Kyouko, and develops feelings for a female reporter; however, when she doubts Agul's benefit, Fujimiya shows resentment. Fujimiya becomes a mysterious figure that appears and disappears seemingly at will, while Agul is perceived first as another force for good, then as a potential menace. Agul at times will help Gaia, but on several occasions they have come into conflict; the second time, Agul tries to destroy the XIG Air Base, but is stopped by Gaia.
At one point, Agul is severely injured, and we find that Fujimiya, too, is gravely wounded in the same place (his side). He returns to the facility where he first joined with Agul, and reentered the tank. Apparently this not only revived Fujimiya, but it also increased Agul's power, for a later fight with the same monster, which takes on the form of a fake Agul results in Agul quickly overpowering his evil twin.
Several incidents change Fujimiya. He finds himself saving a young girl from being crushed by falling debris when a monster destroys a nearby skyscraper. This puzzles Fujimiya, that he should care so much about a human. Yet, his bitterness increases when his beloved Kyouko is killed by a monster ... even though she tries to control the monster herself in an attempt to stop XIG (presumably she believes in Fujimiya's visions, and wishes to destroy mankind to save the Earth). In a fit of rage, Fujimiya, as Agul, begins to drive his force-filled right fist into the Earth. Apparently it is a summons to various beasts that he has fought before, and to others he knows still exist. Unbeknownst to him, it also summons a giant serpent-like beast, the Zoalim, which resembles the great serpent Gaia was fighting when Gamu first discovered him. By this time, though, Fujimiya is drained nearly to death, thanks to the nightly infusion of energy, plus a knock-down drag-out battle with Gaia. He and Gamu help evacuate a hospital, where Fujimiya sees a young boy's crayon drawing of Gaia and Agul joining hands to save the world.
Zoalim begins to enter our world through a giant vortex in the sky, created by the combination of Agul's and Gaia's energies during their battle. Gamu prepares to change to Gaia to battle the monster. Fujimiya tries to talk him out of it, but Gamu realizes that he cannot; he also makes Fujimiya realize that it was through his actions that the Earth -- not just the humans, but the entire planet -- is threatened with destruction by his own actions. This makes Fujimiya realize that he no longer deserves to be an Ultraman, and surrenders the blue Agul-force within his Agulator to Gamu, who takes it inside the Esplender along with the red Gaia-force. Fujimiya walks away, apparently consumed by a fireball shot to Earth by Zoalim.
For the effects on Gamu and Gaia of the exchange of Agul's energy, see the entry on Ultraman Gaia.
Later, Fujimiya discovers that the prediction that humanity was the cause of the Root Destruction was actually placed into the computer by the great Entity of Root Destruction itself, as two more monsters arrive on Earth through a wormhole created by GUARD itself. (The idea was that GUARD would send a pre-emptive strike missile through the wormhole to the planet on the other end, in the hopes of destroying the Entity. The plan failed, but the wormhole allowed the Entity to send two monsters to Earth.) Agul and Gaia finally team up and, together, defeat the monsters. The rivalry has ended, and the Ultra-team has begun.
The series ends with Gaia and Agul fighting a giant swarm of creatures that completely block Earth from the Sun. All transmissions, except for television broadcasts, are blocked. The creatures combine to form one, two, and even 3 great monsters, battling Gaia and Agul almost to exhaustion. Suddenly a gigantic "angel" appears from the wormhole, destroys the great beasts, and recharge Agul and Gaia. This "angel," significantly larger than even Agul and Gaia, turns out to be the Entity of the Root Destruction itself, and sets about defeating the two Ultraman. Their ColorTimers gone dark, the two collapse in a pile, their eyes even going dark. The angel then extracts the essences of Gaia and Agul into herself, causing the giant Ultramen to shrink down to Fujimiya and Gamu. (While XIG had become aware of their secrets a few episodes previously, now the whole world knows.) The two are not dead, though, and are rescued by their friends. Meanwhile, various other Earth monsters appear, trying to fight off the alien invasion, to no avail. Catherine Bach, one of the prettier members of the Alchemy Stars (who also has a "thing" for Gamu), realizes that the Earth monsters have power that could be made useful. Using specially-equipped XIG fighters, the Stars draw off blasts from the monsters (who seem to have some idea what's going on) and transmit the energy to the spot where Gamu and Fujimiya stand. The light re-energizes them, allowing them to become Ultramen one more time. After vaporizing all the critters covering the Earth, they attack the angel with full force, stunning her. She transforms into a horrible monster, and charges the Ultramen. Realizing that their combined energy had summoned Zoalim in the first place, the two fire their beams at a spot between them, creating a mega-beam that shreads the Entity. Earth is finally safe from the Root Destruction, and Gamu & Fujimiya go off on well-earned rests. (The series doesn't state whether they still have the ability to change to Ultramen, should the need arise.)
Fujimiya transforms into Agul via the Agulator. Fujimiya retain the Agulator after surrending its power to Gamu; however, it was little more than a weight on his arm. In frustration, he threw it into the ocean. When the Earth restored Agul, and after Agul V2 rescued Gamu, Fujimiya had a new Agulator on his arm; from this, I presume the Agulator was somehow presented to him by the source of the Agul light (or perhaps the Earth gave it back to him).
Agul's main attacks are the Photon Crusher (a missile of light fired from his head) and the Liquidator (a standard Ultra-style beam). Agul is slightly taller than Gaia normally, weighing in at 52 meters tall; however, like Gaia, he can shrink to "micro size." Like Gamu/Gaia, Fujimiya feels all the injuries inflicted on Agul; in one episode, where Agul is almost impaled, Fujimiya stumbles back to the tank where he first merged with Agul, clutching his side in severe pain. Before surrending the original Agul light to Gamu, Fujimiya was able to call upon some of the shared energy while in human form; for example, he flashed past several guards, knocking them unconscious in the process, with ultra-human speed. Fujimiya did not exhibit these abilities after the Agul V2 power was given to him.
