Makaioshin

[Majin Demigra]

Wouldn't the Demon Gods(Especially Mechikabura) be the closest thing to them?

Mechikabura looks exactly like a Kai when he was returned to his prime, i think UMX said he was on of the candidates to be Time Kaioshin, can make Demons into gods, was said to be the strongest evil in Demon Realm

Plus he Demigra, Putine, and Gravy all used to be in the Heavenly Realm and were banished to the Demon Realm

Chronoa says banished wizards created the shadow world known as Demon Realm

At the present moment, there's just not enough done with the Demon Realm to really know one way or another, but I'm fairly sure that we have yet to see the Makaioshin. When we do, I'm positive it'll be the first thing we hear about him.

Both Demigra and Mechikabura may be evil Supreme Kais ruling the Demon World, thus Makaioshins. Both of them wear green-coloured Potara earrings and only a Supreme Kai may wear them.

But I don't think we will ever see such a villain when Super comes back. They would be way too similiar in concept and in appearance to Zamasu.
