Shinkansen Henkei Robo Shinkalion: THE ANIMATION - S01

To defend Japan from the threat of massive creatures known as Giant Monstrous Beings, the Shinkansen Ultra Evolution Institute created transforming robots called "Shinkalions." Now, as new enemies loom, the institute is developing an advanced model, the "Shinkalion Z," alongside armored support vehicles called "Zailiners"-ordinary trains that transform to enhance the robot's power. A group of children with high compatibility rates are chosen to pilot the Shinkalion Z, teaming up with the institute's staff to battle the returning monsters. But with unknown foes appearing and the meeting of two boys, their mission grows even more challenging.
