Klin is a beautiful planet blessed with an abundance of fresh water. And it is because of this wealth that Waller, a warring empire, invades the planet and ravages it for its liquid wealth.
Two years later, with nearly no water or natural resources left on their planet, the survivors pin their last hopes on two children and send them to Earth, a planet with similar environment to Klin. These two children are Spielban & Diana.
12 years after their arrival, they finally wake up from their sleep. Receiving the knowledge of the history and culture of Earth, they continue their growth as soldiers.
Then, the Wahrer Empire approaches Earth, with the intent of raiding Japan for its water. To stop them and to protect the planet, Spielban & Diana stand up to them, but deceptions, lies, heartache, and the painful truth awaits the two of them...
This is one of the series used as source footage to create VR Troopers.
Jikuu Senshi Spielban provides examples of the following tropes:
- Action Girl: Diana and Helen
- Apocalypse How
- Armies Are Evil
- Big Bad: Emperor Guillotine (Or is it?)
- But Not Too Foreign: Diana's mom is white but she is Japanese...
- Cosmic Retcon/Reset Button: Defeating Wahrer completely negates the events of the series.
- Cool Plane: Jet Gaios and Skulldon Jet.
- "Do It Yourself" Theme Tune: Spielban's dad sings most of the songs for the series.
- Double Weapon: Twin Blade.
- The Dragon: General Deathzero
- Earth All Along: In the Twist Ending, Klin turns out to be Earth in the future, and Spielban and Diana were really sent through time rather than space.
- Drill Tank: Drill Gaios
- Fling a Light into the Future: At first seems to be of the spatial variant. Turns out to be a temporal variant.
- HeelFace Turn: Helen
- Luke, I Am Your Father: Dr. Bio is Spielban's dad.
- The Man Behind the Curtain: Pandora
- Market-Based Title: In Brazil, the series was released as Jaspion 2: Spielvan, pretending to be a sequel to a fellow Metal Hero who was a huge success in the country. But the character was still called Spielban (or rather, "Spielvan") there.
- Meaningful Name: Wahrer=pun on water.
- Super Soldier
- Transforming Mecha: Gran Nasca Mothership into Combat Formation and Big Bang Cannon.
