M1

A super express train called the Inazuma was off on its maiden voyage carrying many passengers, one of which was carrying a suitcase containing an alien substance called M1. When his suitcase was confiscated for security measures M1 grew into an ape-like creature and scared one of the crew members. After doing so, M1 took control of the train and everything seemed to be fine until the Inazuma was moving too fast. Fortunately, most of the train was split to save the passengers, although M1 and a small boy were still in the locomotive with the controls over heated. Although the Inazuma collided with a bulldozer and two buildings, the boy and M1 managed to escape using M1's emergency escape pod.
