Intro： Absolutely Invincible Thunder God KingThe evil army 'Jaker Empire' from the fifth dimension has begun preparations to attack Earth. Standing in their way is Eldoran, who has protected Earth since ancient times, along with his piloted vehicle, the Thunder King. However, the Thunder King is injured by the despicable tactics of the Empire's commander, Beluseth, and crashes to Earth... The Thunder King falls into Yangsheng Academy, and Eldoran entrusts the Thunder Metal that controls the Thunder King to the students of Class 5-3 before passing away... Thus, the 'Earth Defense Organization' composed solely of elementary school students is formed. The next day, the evil robot Abysmal Beast, Aetisus, from the Jaker Empire appears. At this moment, the Thunder Metal in the students' hands shines brightly, and when Maria Shiratori places the Thunder Metal on the desk, the classroom transforms into a command center. Three students, Nikaido Jin, Tsukijo Asuka, and Hoshiyama Koer, become the pilots of the Sword King, Phoenix, and Beast King, respectively, and they launch an assault against the evil beasts of the 'Jaker Empire.' During the battle, Kojima Manabu discovers that the three robots can combine, and the three of them ultimately merge into the Thunder King, successfully defeating the evil beast. Thus begins the battle between the 'Earth Defense Organization' composed of elementary school students and the evil Jaker Empire...
