Sport Ranger

Starhunter is an alien tribe that steals all life energy on other planets, gathering the energy in the sixth dimension using "King Medal" and bringing it under their control. Soon they created "Knight Medal" when "King Medal" was not able to absorb all the energy. Hoping to conquer the Earth in one fell swoop, since they believed it would not offer much resistance, they brought along both medals. Fortunately, the ship carrying both medals got hit by crossfire in a war that was going on down on Earth. The medals were lost as the ship exploded in Siberia. Starhunter was forced to retreat and create new medals.

One of the medals was broken into 5 pieces. The broken medal was taken by researchers headed by Dr. Earth, and the complete medal was taken by Dr. Heart. One day, Heart's research lab exploded and the medal was nowhere to be found. Later Dr. Earth realized that monsters that had begun to appear were humans that had absorbed the energy from the missing medal when the lab exploded.

Upon further research, Dr. Earth created "SportDetector" to control the 5 broken pieces and special suits to utilize each piece's unique power. He gave five youngsters the suits to stop these monsters.

Meanwhile, Starhunter is preparing their new invasion of Earth.

It is then passed from member to member and Boxing Red punches it into the enemy. The Sport Rangers' first attempt to use the Super Attack Ball was unsuccessful, they were unable to smoothly pass it to each other. To improve on their teamwork, they lined up with their legs strapped to the person next to them and tried to run together. With their new team skills, they were able to complete the combination attack during their second try.

• Spirit Robo: The team's giant mecha that is composed of the five Spirit Fighters. It was developed by Dr. Earth with the assistance of Professor Josh in episode 10. Its main weapon is the sword, which performs its finishing move which is called the Meteor Storm Slash. The Spirit Robo is similar to several recent Super Sentai combining robos & Power Ranger Megazords (starting with the Senpuujin from "Ninpuu Sentai Hurricanger" in 2002 & Storm Megazord from Power Rangers Ninja Storm in 2003) in that the Sport Rangers remain in their individual cockpits rather coming together into a single cockpit when the combination is formed.
