The Omiya team was sent to the Moji Branch to train Rei and befriend him. Additionally, Rei was a bit of a boy genius, and even helped in building it. After the destruction of the Black Shinkalion Ogre, Rei quit as a driver for good and returned to his normal life, with the 800 on standby should another threat arise.
The 800 has a sharper nose than that of the 700 series, featuring a sharper one instead. The livery is white, with a red stripe and roof.
The 800, when transformed, becomes a humanoid mech, which still keeps it's chest the same the nose of it's shinkansen mode and has access to the Pantograph Arrow, a crossbow which can firing quick shots or charge a large energy arrow for the finisher. The 800 is also equipped with the large Swallow Wings on it's back and the smaller sub wings on it's legs, making it the first flying shinkalion.
- Unlike the other shinkalions, the distinctive locomotive leg shells on most 2 car formations end up as the Swallow Wings rather than folded on the legs.
