Plot
The series follows the adventures of Prince Susumu Hori of the Lucky Star Kingdom, who must overcome dangerous obstacles and to defeat Team Ankoku for killing the Lucky Star Kingdom's monarch. At the beginning of his saga, he meets a 15-year-old boy named Wataru Hoshi who is part of the Space Ninja Team Star Trigon and discovers a series of triangle-like weapons called Trigons, which he can ultimately use to defeat Team Ankoku altogether. As the series progresses, Dr. Manhole is killed numerous times, while being revived by Keel, Eguri, and Kowars.

Differences between the Japanese and US versions

 * Wataru and Susumu use lightsabers instead of swords due to the name change to match the theme. Wataru's lightsaber is blue while Susumu's lightsaber is green.
 * Most of the slashing sound effects have been changed to lightsaber sound effects.
