Plot The Waller Empire destroys the planet Clin in search of water for its deity. Two Clinian children, Spielban and Diana, escape to Earth aboard the Grand Nasca. The two grow up during the long journey and don High Tech Crystal Suits to defeat the Waller who have come to Earth in search of more water.

Unknown to Spielban at the start of the series his father and sister have been made members of the Waller against their will.

Characters Grand Nasca crew Spielban's group is based on the super dimensional mothership Grand Nasca, the source of Spielban and Diana's armor and vehicles. Diana also pilots it to see above the battlefield while Spielban is in Gaios. Its projectile weapons are Nasca Missiles and Nasca Rockets. It also transforms into the Big Bang Cannon, a bazooka-type weapon that Spielban can use. It can also go into "Combat Formation", where it becomes a giant robot that performs the "Nasca Hyper Crush" where it stomps General Deathzero's tank vehicles, shoot beams from its eyes (the Excel Beam), and uses "Knuckle Bomber", where it punches General Deathzero's fighter planes in mid-air.

: Anna and Ben's younger son and Helen's younger brother. A 20-year-old man from the planet Clin, he assumed the alias of while on Earth. When he shouts "Kesshou!" ("Crystallize"), the Grand Nasca showers "Clin Metal Super Corpuscles" upon him, which crystallize to form the silver, black and red suit around his body in 10 microseconds. Spielban's primary weapon is a sword which then becomes the Twin Blade, a double-edged laser lance used to destroy the mechanoids and lifeforms with his "Arc Impulse" attack. His name is a reference to American director Steven Spielberg. Spiel is derived from Spielberg, while ban is derived from Esteban''', a Spanish variant of the English name Steven. : Marine's only daughter. She is 18 years old and Spielban's partner fighting as by performing the same techniques as Spielban to activate her own white and red suit. When she shouts "Kesshou!" ("Crystallize"), the Grand Nasca showers "Clin Metal Super Corpuscles" upon her, which crystallize to form the white red suit around her body in 10 microseconds. Like Spielban, Diana is quite capable in a fight both in and out of uniform and carries with her the Lady Sniper which acts as her own personal weapon. She primarily serves as a backup for Spielban when they battle the mechanoids or when the Waller send out assault vehicles. There have been times when the Waller have turned their attention towards her once they recognized how much of a threat to them she can be. A running gag on the show was that she would use her charm and sex appeal on the Kinclons, distracting them from their duties while she made her move. Another gag is that she sometimes uses her rear end to attack the Kinclons, which apparently knocks them out cold. : Anna and Ben's daughter and Spielban's older sister is 22 and was captured by the Waller Empire when she was only a child. She was forced to witness Waller turning her father into Dr. Bio. Later, Dr. Bio was instructed to do the very same to her as well, converting her into with a secondary persona that activates via remote control.

After Pandora's trap almost kills her, Bio places the comatose Helen in a protective tube. When Diana learns that Helen survived, she and Spielban save her, as Dr. Bio destroys the remote control, deactivating the Hellvira persona. Soon after, Helen joins her brother in the fight against the Waller as . When she shouts "Kesshou!" ("Crystallize"), Helen is equipped with a high-tech crystal armor identical to Diana's and is and armed with the double-sided Helen Cutter.

Waller Empire The is the antagonistic group in Spielban. From their winged turtle-like mobile fortress called the Waller Castle Gamedeath, they search for water throughout the universe on the notion that they are sustaining the life .

: Originally a giant starfish that needs vast amounts of water to survive, Pandora is the leader of Waller who conceived the Waller deity to establish her Empire while instilling fear in her subordinates. In the two-part series finale after her other followers have died, Pandora personally fights Spielban while splitting into the forms of and the starfish-like . Thought to have been destroyed, Pandora endures and reveals herself as Waller's true leader when she reverted Dr. Bio to Ben for his attempt to sabotage the Gamedeath in her absence. Pandora once more splits into her two forms to battle Spielban's group before merging into a more powerful to finish them off. But Ben injects Pandora with a virus that is harming her at a cellular level, allowing Spielban to kill her as she reverts to her natural form. : He claims to be a descendant of Waller, which therefore makes him a relative of Pandora. He was summoned from the 23rd century by Poss from the life of a street beggar to help Pandora in the present. Though he treats his followers and allies as somewhat disposable, he remains eternally loyal to his Queen. Guillowtine kept Poss for a pet. He dislikes Youki from the start, sensing that this new general will betray the Waller. Guillowtine is dressed similarly to a rebel biker. He falls into a dimensional rift and returns as a ghost. As a ghostly form he invades the Grand Nasca and attempts to torture Helen. In this form, his right arm has been replaced by a small, living, snake-like monster which he could launch at the heroes. He was eventually destroyed by Spielban with the help of the Grand Nasca's energy. : Poss is a talking gerbil Battle Lifeform who summoned Emperor Guillowtine. He told Guillowtine that his life as a beggar was caused by Spielban. Emperor Guillowtine kept Poss as a pet who is later left to Pandora, after he is rifted and destroyed. Poss was later contained and destroyed by Dr. Ben during the finale. : Leader of Waller's Battle Mechanoids he is a black-armored android who is programmed with a knowledge of all tactics. He can transform into the Deathzero Torpedo, a black headed missile that is launched from a catapult. He transforms into this form twice during the series (Episodes 24 and 42) which coincidentally were the only two times he battled Spielban himself. It was strongly hinted that Deathzero was attracted to Diana. He later challenges Spielban to a second battle (both inside and outside of his tank), now having become/been promoted to Super General and powered with a 10,000 volt cylinder given to him by Pandora. Deathzero is destroyed by Spielban soon afterwards, with Spielban using his Arc Impulse. : Formerly Spielban's father Doctor Ben, he was captured by Deathzero and converted into an inhuman being to serve the Waller Empire as its scientist and leader of the Biohumans and Battle-Lifeforms he creates with Lifeform Modification Surgery. He was also protective of Helen and constantly watched over her like a father would. Bio can unleash vine-like appendages from his arms and wields a giant sword in battle. In his first and only battle against Spielban, he mutated and ended up in a Bioroid monster form called . Bioroid Bio's abilities included transforming into plant life or slime and summoning small bee-like creatures and tentacles from his body. In this battle Helen tries to protect, and prevent him from fighting, his son Spielban before she was forcibly transformed into Hellvira. Pandora sets up an explosive trap to kill Bio, Helen, Diana, and Spielban all at once though, unfortunately for her, all four of them survive. Bio uses his slime morphing ability to pull his daughter and himself to safety. After surviving the battle, Bio returns to the Empire and transforms into a floating brain with eyeballs and a spinal cord. Dr. Bio breaks Helen's remote control and is attacked by Deathzero under Pandora's orders. Afterwards, Pandora takes away his privilege of moving around freely and imprisons him in a water-filled glass tube. He returns to his Dr. Bio form, with Pandora's efforts, and is reverted to his original human form when he attempted to sabotage the Gamedeath. Weakened as a result, he killed the gerbil he created when it attempted to stop him. Ben acquires one of the viruses he developed as Bio and uses it on Pandora, who killed him in the process. But Ben is restored to life in the alternate future timeline in which the Waller Empire never existed. : Leader of the Waller's all-female spy army. At one point, she tricks the owner of the Edison shop named Daigorou Koyama into building a prototype for a Battle Mechanoid. She often spies and comes up with cruel plans for the Waller, but is not one for combat. After Licky interferes with Youki's plan, Pandora angrily turns her into a stone statue for Youki to use as his throne. After Youki's death, the talking gerbil was given this throne for his own. During the finale, it disappears when it was presumably destroyed when the Gamedeath exploded. : Rikki's aides and fellow spies in Waller's all-female Spy Army. They assist Rikki in almost every evil scheme she creates and employs against Spielban and Diana. Spielban manages to destroy them both with a single strike of his sword when they tried to attack him during a vulnerable time per Guillotine's orders. Unfortunately for them he had gained a second wind, shocking the Waller. Even if he had not they would have been destroyed anyway, as the daggers exploded during the battle. Guillotine had tricked them into wielding the daggers, having promised them an increase in rank for killing Spielban. Upon being destroyed, they were revealed to be robots as they leave behind mechanical pieces and chunks of metal.
