Epsilon  

, イプシロン

One of the Mecha Nyanbo, who assists Alpha in locating UFO fragments, resembles a tank that can morph. The symbol "ε (epsilon)" identifies it. Despite being devoted to Alpha, they depart at 5 pm, regardless of their workload. Alpha does not refer to them by name individually. These Mecha Nyanbo have expressed dissatisfaction with the workplace and compensation system.
