Iczer Reborn, known in Japan as , is a 6-episode Original Video Animation series. It is the sequel to Fight!! Iczer One. Although originally released in North America on VHS and Laserdisc under the title "Iczer-3" (taken from its Japanese name), Central Park Media renamed it "Iczer Reborn" for the DVD release.

A sound novel trilogy, based on the manga version of the OVA and released as , functions as a sequel to the manga version of Fight!! Iczer-1, and features a 19-year-old Nagisa Kanō as the main heroine. The trilogy was released on three cassette tapes prior to the OVA.

Plot Nagisa Kasumi (the granddaughter of Nagisa Kanou, the heroine of "Fight! Iczer One") has a job as a delivery girl and makes her deliveries with a girl named Kawai on a base in the Moon. The two encounter a new race of alien villains, but are saved by Iczer-3! While Iczer-1 recovers from her long battle against Big Gold's legacy and self-proclaimed successor, Neos Gold, Sister Grey sends young Iczer-3 to Earth, and the child turns out to be the best hope against the new threat.

Characters

Iczer-3 is the heroine of the series. She is the third and final gynoid produced in the Iczer line by the Cthulhu, physically appearing to be ten years old, and is the younger sister of Iczer-1. After Iczer-1 is badly injured in a battle against Neos Gold, Iczer-3 is sent to Earth to defend against Neos' forces in her stead. Iczer-3's battle strength is equal to that of Iczer-1, but she lacks the experience and maturity to use that strength properly at first. This leads to her early battle tactics being rather childish and playful. She forms a close bond with Nagisa Kasumi, and develops a deep love for her.

Like her elder sister, Iczer-3 wields energy blades in battle, preferring to use twin swords as opposed to the single blade used by Iczer-1, and is also able to summon to battle larger foes if necessary. Her favorite special attack is the , a powerful shoulder-charge that is capable of inflicting major damage to the enemy.

Nagisa is the secondary heroine, and the fourteen-year-old partner of Iczer-3. She lives on a lunar colony with her best friend Kawai Shizuka, and works part-time at a fast-food delivery service. When Neos Gold's forces attack, she is at the Moonbase delivering food to the crew of the . When Fiber takes Kawai hostage, she offers herself instead, and is about to be attacked when Iczer-3 intervenes. From that point on, she becomes a key player in the war against Neos Gold's evil forces.

As Iczer-3's partner, she develops a powerful telepathic bond with the gynoid. Shortly after, she also begins to frequently experience strange dreams. These dreams are in fact a flashback to the Iczer-1 OVA, revealing that she is the granddaughter of Iczer-1's partner, Nagisa Kanō. Like her grandmother before her, Nagisa's emotional state is the key to powering Iczer Robo in battle, though it is later revealed that is the core power source. She also acts as Iczer-3's guardian while she is on Earth, and when Iczer-1 arrives on Earth, Nagisa seems to immediately recognize her. Likewise, due to her intimate connection with Nagisa's grandmother, Iczer-1 knows Nagisa very well.

Nagisa later appears in the drama CD trilogy of the sequel series, Iczer Girl Iczelion. After Iczer-3 contacts her on Earth, she inherits the powers of the living robotic armor , becoming the titular .

Atros is a clone of Iczer-3 created by Neos Gold using the stolen Iczelio energy halfway through the series. Unlike Iczer-3, Atros loves to fight, and does not hesitate to attack Iczer-3 and her friends. Atros sees Neos Gold as her mother, and fought against Iczer-3 and the crew of the Queen Fuji to enable her mother to rule the world.

When she first appeared, Atros killed Bigro with a single attack, before challenging Iczer-3 to a duel. It was quickly revealed that she possessed all of Iczer-3's powers, and indeed proved to be an even match for her. It was only upon seeing Nagisa that Atros retreated to make sense of the strange feelings that were overwhelming her. Neos berated her creation, and told her not to return until Iczer-3 was dead. Atros decided the quickest way to achieve this was to eliminate Nagisa first. She failed in her second attempt as well, when Nagisa tried to sway Atros to their side. Eventually, Neos replaces Atros with Iczer-2, which proved to be the final straw for Atros. With her mother turning her back on her, Atros switched sides, choosing to think of Nagisa as her mother, and joined forces with Iczer-3 to launch a final assault on Neos' home base, and working together in concert with Iczer-3, successfully brought down the barrier around the fortress. Neos was not about to let her creation's betrayal go unpunished, however, and launched a powerful attack against Atros, mortally wounding her. Atros died in Nagisa's arms, as Iczer-3 mourned the death of a sister.

Kawai is Nagisa's best friend and coworker. She works with Nagisa part-time at a fast-food delivery service, and is nearly killed by Fiber when Neos' forces attack the moonbase. She later becomes a member of the Queen Fuji crew along with Nagisa and Iczer-3. Kawai is a tender-hearted person, but she is deathly afraid of insects. She also worries for the safety of her parents, who live on Earth.

Yajin is a part-time worker at the moonbase, where he helps to fine-tune the guns on the base's various warships, including the Queen Fuji. A fifteen-year-old young man of Chinese descent, he can be quite sarcastic at times, and has lied to Iczer-3 on at least two separate occasions. Yajin has a massive crush on Nagisa, and after Iczer-3 summoned Iczer-Robo to defeat Insect, he took it upon himself to punish Iczer-3, throwing her in the brig for endangering Nagisa.

He is the sole officer in charge of the Queen Fuji's weapons systems, and is also a fairly good shot. After Nagisa discovers Golem's weak point during her transformation into her "Golem Jet" mode, Yajin damages her with a beam cannon shot to the shoulder.

During the Iczer-3 CD dramas, it is revealed Yajin was born in Osaka, Japan, and also reveals his cooking skills during an impromptu cookoff with Atros. (We later find out that his parents owned a famous Chinese restaurant.) Although he is in love with Nagisa, he started dating Kawai during the events of the "Iczelion" novelization.

Rob is the 24-year-old chief engineer of the Queen Fuji. Unlike the rest of the crew, Rob is well built, having logged many hours of sometimes-backbreaking labor. In addition, as one would expect, he also possesses above-average physical strength. In contrast to his physical appearance, Rob is a very gentle soul at heart.

He has a lot of pride in the Queen Fuji as a warship, as well as in his status as a ranking officer in her crew. He becomes quite impressed with Iczer-3's strength in battle, even going so far as to gain a very rudimentary understanding of the alien technology involved in her creation. As the series progresses, he slowly develops a romantic relationship with the captain of the Queen Fuji, Candy Barts.

During a "gag drama" episode of the Iczer-3 CD Drama, Rob remodels the galley in a very mad scientist-like fashion, embarrassing Candy at its "anime-like magnificence".

Candy is the 25-year-old female captain of the Queen Fuji. Her calm demeanor allows her to achieve results more quickly than others can. During Earth's war against Neos Gold, she is the commander of the only warship able to fight back.

In the radio drama novelization of Iczelion, she is Rob's girlfriend, and often worries about the fate of the Earth, as well as for Iczer-3's safety.

Iczer-1 is the previous series' heroine, prototype for all Iczer series gynoids, and leader of the Cthulhu. She fought with the nefarious Big Gold in the previous series, and emerged the undisputed victor. Sadly, she had to part ways with her much-beloved Nagisa at the end of the series, understanding that Earth should follow its own destiny. But she never truly left for good, always keeping a watchful eye over Earth from afar.

Iczer-1 does battle with Neos Gold in the prologue of episode 1; the violent confrontation between the two ends in a stalemate, as Neos acknowledges that neither of them has the strength to continue the fight at that point. She then spends the majority of the OVA recovering in a healing chamber aboard the Cthulhu ship, sending Iczer-3 to defend Earth, which Neos has now targeted, in her place.

Iczer-1 physically appears to be around twenty years old, though she is likely to be far older, and as a gynoid, may even be immortal. Like all Iczer gynoids, she is capable of numerous superhuman feats, such as flight, teleportation, and telepathy. She also holds a large soft spot for her sisters, and may even think of Nagisa Kasumi as her own granddaughter, though this is unconfirmed. As in the previous OVA, Iczer-1 is voiced by Yuriko Yamamoto.

Iczer-2 is Iczer-1's evil twin sister, originally created by Big Gold in the previous OVA series specifically to kill Iczer-1. She was slain by Iczer-1 in battle, who avenged the death of her partner, Nagisa Kanō. After Atros' repeated failures to kill Iczer-3 and destroy the Queen Fuji, Neos Gold starts to realize that the only one capable of defeating Iczer-3 is another Iczer gynoid, and resurrects Iczer-2 to that end. However, Iczer-2 refuses to submit to Neos' will, stating her only desire is to fight Iczer-1. In response, Neos Gold tells her that by killing Iczer-3, Iczer-1 is sure to return to avenge her little sister's death.

When Iczer-2 and Iczer-3 finally meet in battle, Iczer-3 is quickly outclassed by the more experienced Iczer-2, who seems to only be toying with her. She tells Iczer-3 the reason the Iczers were created is to fight, a philosophy that Iczer-3 rejects. Later, after a fully rejuvenated Iczer-1 returns to Earth to aid Iczer-3, Iczer-2 gets her shot at revenge against her elder sister. Though she fights with all her strength, Iczer-2 is once again defeated by Iczer-1, who decides to spare her life in the end, saying she will not let another sister fall in battle. Iczer-2 then aids her sisters in the final defeat of Neos Gold, though it is Iczer-3 who delivers the finishing blow. At series' end, Iczer-2 leaves Earth to wander the Universe, thinking perhaps they will all meet again. Her current location is unknown.

Sister Grey is a close friend of Iczer-1, and the creator/mother of Iczer-3. When Iczer-1 sensed Neos was attacking Earth, Sister Grey sent Iczer-3 to Earth in her place.

Neos Gold is the series' primary antagonist. A machine-like life-form created by Big Gold's computer terminal, she refers to Big Gold, Iczer-1's nemesis, as her mother, and has indeed inherited every single bit of Big Gold's malevolent personality.

In the very beginning of the series, she engages Iczer-1 in an epic battle that ends in a stalemate, with both combatants exhausted and badly wounded. Deciding to postpone the finish of their battle until both of them have recovered, Neos declares to Iczer-1 where she has chosen to finish their battle: Earth. She then sends her four generals to Earth, in order to wipe out any resistance before her arrival. Neos hacks into every computer network on Earth, and makes her presence known to humanity, before launching a preemptive attack that wipes out more than half of Earth's military in one stroke. In just five minutes, Neos wipes out nearly two-thirds of humanity, and reduces every major city on Earth to ruins.
