You know what's weird? Like, every place in DBZ has one leader for like the entire planet. Sayains all lived under one king. The nameks had Guru. The planet Nappa and Vegeta destroyed had a king. there's a king for the entire universe and all that... I think even earth had a king/president with that dog looking dude. I'm just surprised every race had one union, no factions or anything to split them up.
