Shinkansen Henkei Robo Shinkalion

Several incidents of monster attacks from a mysterious group named Kitoralsus appeared suddenly in Japan after the appearance of the mysterious Black Shinkansen. In response, a secret organization called Shinkansen Ultra Evolution Institute was established in order to investigate the Black Shinkansen and its relations to the attacks using Shinkalions, bullet trains that turn into giant robots. However one day, Hayato Hayasugi, a young grade schooler who is a big railfan due to his father being a staff in the Railway Museum, accidentally got involved in the recent attack by the monsters and discovered his father's secret working with the Shinkansen Ultra Evolution Institute. Hayato shows a surprising amount of aptitude as a Shinkalion driver, based on him using a training application on his father's tablet that he mistook for a mobile game. Despite initial concerns from the adult members of the organization about having children as drivers, Hayato joins several other kids in using Shinkalions to willingly fight against the threat of the Kitoralsus.

About half a year after the defeat of the Kitoralsus, giant monstrous beings suddenly appear from space lead by both Nahane and Ohanefu, and are planning to take over the Earth. During these attacks, the Shinkansen Ultra Evolution Institute has been busy developing a new prototype unit - the Shinkalion ALFA-X. Suddenly, a 9-year old Hokuto appears from across time and space. Having no choice, the Shinkansen Ultra Evolution Institute appointed the young Hokuto to become the driver of the Shinkalion ALFA-X and bringing in the teams from all the branches across Japan as the last line of defense against the invaders threatening the planet.

In preparation for the attack of new enemies, the Ultra Evolution Institute is developing a new type of robot called "Shinkalion Z" as well as new armed enhancement rolling stocks known as "Zailiners" that transform from conventional trains to power up the "Shinkalion Z". The children who became the drivers of "Shinkalion Z" with a high compatible rate will work together with the institute staff members to confront the giant monstrous beings that reappeared! The emergence of unknown enemies- And the encounter of two boys.

The original Shinkalion toy franchise was released as a spin-off of the Plarail franchise on March 16, 2015.
