|Home world:||Planet Mephisto (Presumably)|
|Number of appearances:||TBA|
Much of his history is unknown, but he has presumably been on Earth for sometime.
He is Adad's immediate superior. After the incident with Pigmon, Edo appeared to him to question him about the Bar Codes case.
Ada later appeared, and while the two discussed the bar codes, he instead gave Adad another mission.
Powers and Abilities
- Mimicry: The ambassador takes the form of a human, instead of appearing in his own form.
- Political Power: He holds influence and authority over Adad and Ed, thus he has influence over the SSSP. He also has connections to World Governments due to Earth joining the alliance.
- He is the first alien, in the manga series at least, to appear first in his human form, having appeared before Yapool.
- Within the English Translation, he was first introduced as Mephisto Ambassador, later on however, he was called Ambassador Mephisto, making it unclear if Mephisto, is his planet's name or his personal name.
