A sequel series called Tekkaman Blade II, which is set ten years after the first series and follows the events of the second Radam invasion, was released as a series of six OVAs in Japan from July 21, 1994, to April 21, 1995. A video game based on the series, titled Uchū no Kishi: Tekkaman Blade, was released in Japan on July 30, 1993.

During the United Earth Year 192, the Earth is under attack from an alien race known as the Radam, whose forces are composed of bug-like monsters and by armored warriors known as Tekkamen. The Tekkamen are humans who transform themselves using a crystal that endows them with impenetrable armor, superhuman strength, flight, energy weapons, and a lance. The Radam's spaceship lies dormant on the dark side of the Moon where the Radam wait for it to be repaired. Unlike the other Tekkamen, Blade fights to defend the Earth and is free of the mind control which the Radam have imposed on the Tekkamen.
Before the start of the Radam invasion, a deep space exploration ship called the Argos, crewed by the Aibas and their friends, discover the Radam spaceship lying dormant in the outer rings of Saturn. While exploring the Radam ship, Radam pods capture the crew and turn them into Tekkamen while Argos is assimilated. Takaya's father, rejected by the Radam pods, frees Takaya before he is fully converted and puts him into an escape pod before activating the ArgosTemplate:' self-destruct. When the Argos explodes, the Radam spaceship crash lands on the dark side of the Moon. In his Tekkaman armor, Takaya spends six months drifting back to Earth in his escape pod. By the time he arrives, the Radam have begun their invasion. Takaya bursts free from his escape pod and attacks the Radam forces, which draws Tekkaman Dagger's attention and causes the two to fight. After his fight with Dagger, Blade crashes down to Earth where he is discovered by two of the Space Knights, Noal Vereuse and Aki Kisaragi, who take him back to their headquarters.
Fighting against the Radam and their Tekkamen are the Space Knights. Led by Commander Heinrich von Freeman, the Space Knights are a special defense force consisting of Noal, the pilot of the Space Knights' ship the Blue Earth; Aki, the Blue EarthTemplate:'s navigator; Milly, the communications operator; Levin, computer mechanic; and Honda, mechanic.
In the beginning, Takaya is hostile towards the Space Knights. However, as time progresses, he begins to respect the Space Knights for their dedication in even the toughest of situations and develops a romantic relationship with Aki. The Space Knights, with the help of Takaya, begin to repel the Radam forces until Blade's crystal is shattered during a battle with Dagger, rendering him unable to transform. Levin develops a battle robot named Pegas which contains the shards of Blade's crystal and allows him to transform again. Pegas and Blade become friends. In his first transformation using Pegas, Blade challenges Dagger and kills him.
Eventually, four more Tekkamen (Tekkaman Lance, Tekkaman Axe, and Tekkaman Sword, led by Blade's twin brother Tekkaman Evil) arrive on Earth to challenge Blade. Blade's sister Miyuki, Tekkaman Rapier, also arrives on Earth. However, like Blade, she is not under the control of the Radam. Miyuki arrives on Earth very ill and is given a blood transfusion from Takaya and Aki. Evil, Lance, Axe, and Sword attack the Space Knights' base and attempt to kill Miyuki. Although outnumbered, Miyuki fights the four Tekkamen and self-destructs in an attempt to destroy them. Blade, now left without a family, resolves to destroy the Radam and manages to kill Lance and Axe. He later gains the power to attain Blaster Tekkaman mode, although it is found that, in using this mode, Blade loses his memories. Evil is given the same ability, as well, in order to serve as last line of defense of Omega, the Radam leader.
At the end of the war, Blade and Evil meet for the last time. The two of them fight and Blade kills Evil. As he dies, Evil is freed from the Radam's mind control and hands his crystal to Blade, telling him that Blade will need its power to reach the Radam spaceship. Balzac kills Sword as they both burn up in the Earth's atmosphere.
Blade takes off on Pegas and arrives on the Moon, where he confronts the Radam leader Tekkaman Omega, who reveals that he is Blade's older brother Kengo. Omega begins to resurrect the Radam spaceship and takes off towards Earth. Blade attacks Omega, who proves too powerful and easily defeats Blade. Omega is about to kill Blade when Pegas steps in front of the killing blow and sacrifices itself. Pegas' destruction enrages Blade and causes him to transform into Blaster Tekkaman mode for the last time. Blade kills Omega and causes the Radam spaceship to explode. The remnants of the Radam spaceship fall to Earth along with Blade, now stripped of his armor.
The series ends with Blade and Aki watching the sunset and Noal recalling what a miracle it was that he and Blade survived the war. However, Blade is now bound to a wheelchair and completely amnesiac.
