A tyrant who rules the undersea world with an iron fist, and leader of the Poseidon family. He fears the survival of the Tritons, so he intends to exterminate Triton and end his family line forever. To that end, he sends his 33 children - each more hideous than the last - to hunt them down.
There's really not much to be said about Azarashi. Another of Osamu Tezuka's "old men with interesting noustaches", his placid demeanour has relegated him to a few bit parts playing old men or just another face in the crowd.
One look at Tonpachi and you just know he's a low level thug and general ruffian. Not terribly bright, he's usually brought in by some other mid-level Tezuka boss, be it Hamegg, Lamp or Tonshipei, to act as the muscle. He's more of a safety in numbers kind of guy, so he doesn't usually work alone.
A bit of an enigma, Jusaburo Kuruma seems to be the kind of guy who's always just spoiling for a fight. As such, he's usually cast in the role of the violent antagonist. He usually shows up as a high school thug or a soldier of some kind.
