Who is the ruler of the DB world?

Kami watches over the world, but he doesn't really rule it.
Is the Dog King the ruler of the entire DB world? I feel that was implied with Piccolo Jr. taking over.

I believe we see the Dog King also in the Buu Saga but that may be filler.

[PhantomSaiyan]

Yes, Dog King

And I feel that the RRA isn't the national/world army but a separate movement. Is there anything known about this? They don't feel government sanctioned.

The Dog is like the ¨president of the world¨ however it is very clear that some character hold political (?) power such as Mr. Satan, and the RedRibbon never really dissapeared (DB's soviet's union?).

The tenkaichi budokai people must be rich and powerful AF as well, because of the business of sports gambling, like the F1, NFL, the FIFA or any other mayor sport really.

Finally, Capsule Corp seems to be a monopoly in technology (Apple? Meta? envidia?) which (metaphorically speaking) makes them rule the world too.
