Ziggy Space-Rat is the coolest two- feet-rat of the galaxy - and the meanest: the little critter enjoys blowing up whole planets. And if there's no planet, then something else...
Stevie Lucas
Stevie Lucas is the captain of the spaceship "H.R. Lucky Star" and somewhat like Ziggys master. He is a nice rather guy, so he and Ziggy don't go along well all the time.
T'Pow
T'Pow, a Vulvanian, always acts logically - meaning that he runs away and hides if there might be any danger. And this wimp belongs to Stevies and Ziggys crew...
King Wakara
King Wakara, the leader of the Malstrombarbarians, belongs to the people of Yamunari. Though he actually isn't a real king, he is respected and has great influence within the worldisland-empire. And he can (and will) call some hundret starcruisers if somebody annoys him!
Tirami-Sue
Tirami-Sue is the adopted daughter of King Wakara and a space-pirate. She's always fighting with Stevie, though they both have a crush on each other.
