Getsuei (ゲツエイ) is the Trainbots' "night fighter". When the lights get low, Getsuei really shines (ha ha), able to sneak up and take out opponents easily even under the worst visibility conditions. On the other hand, he's not so good in the daytime. In fact, he tends to get a little sluggish and daydreamy when the sun is out.
His alt-mode is a EF 65 Train Engine.
