Shinkansen Henkei Robo Shinkalion: THE ANIMATION

To defend Japan from the threat of mysterious Giant Monstrous Beings, the Shinkansen Ultra Evolution Institute created "Shinkansen Transformable Robot Shinkalions." Now, as new enemies emerge, the institute is working on an advanced robot called "Shinkalion Z" and special armored vehicles named "Zailiners"-modified trains that transform to enhance the robot's power. Children with high compatibility rates are chosen as pilots for the Shinkalion Z, teaming up with the institute's staff to battle the returning giant monsters. Amid the chaos, an unknown enemy appears-and two boys cross paths.
