Mappo

Mappo (マッポ) is the first robot created by Ejinso. He works as the island's law enforcement because the island lacked the resources to hire a human police force.

Because he is an early model, model C-001, his robot siblings tend to dislike him or push him around. He also seems to strongly dislike or fear Ejinso, refusing to enter the Ejinso Institute early in the game and proclaiming that Ejinso is not his father. However, he does refer to the other robots as his siblings.

He works closely with the Mayer and likes Tao. He is also able to translate Tao's barking and seems to be generally fond of dogs.

He speaks almost entirely in katakana. Sometimes, he reverses the last syllables in words.

Mappo also makes an appearance in the game Captain Rainbow, alongside Tao.
