In the year 2020, Earth is menaced by the android Zelda, Imperial Queen of Planet Guk, and her hideous 'family'. They are bent on destroying all humanoid life in the galaxy, and Earth is their next target! Zelda's 'son' Yung-Star fancies himself as an evil genius, but it is soon clear that he isn't up to the job, while her 'sister' Cy-Star does not care about the invasion of Earth, so long as she's wearing the right outfit for the occasion. Now they are joined by Cy-Star's son It-Star, an evil genius with dual personalities - a charming little girl and a horrid little boy. In their Mars-based fleet of ships, Zelda carries monsters collected from throughout the universe held in suspended animation, ready to be inflicted upon the unsuspecting people of Planet Earth. Terrahawks is led by the clone Dr 'Tiger' Ninestein assisted by Mary Falconer, Hiro, Hawkeye and the international pop star Kate Kestrel, spherical bouncing robot Zeroids. In their secret South American base Hawknest, with the world's most advanced fighting machines at their disposal, the Terrahawks wage a never ending war against the invaders from Mars
1. Two for the Price of One It's time for the final battle as Tiger Ninestein plans a surprise attack on Zelda's martian base. Zelda's mind, through, is on other things as Cystar is about to have the universe's first android baby! 2. Child's Play Cystar's baby, Itstar, proves to take after Zelda, rather than his/her mother, adn produces a super powerful explosive. When Zelda uses it to plant a bomb under the Trans-Siberian pipline the Terrahawks must act, though they know it may be a trap. 3. Jolly Roger One Zelda teams up with her most bizarre ally yet, the pirate Captan Goat with his Space Galleon ready to take on the ultra-modern Terrahawk fleet. Goat still does things the old fashioned way and aims to have Tiger walk the plank. 4. Runaway Zelda should know by now that Yungstar is always captured when he goes on a mission, so why would she allow her idiot son to run away from home? It's all a clever plot, naturally, and one which may finally reveal to Zelda the location of Hawknest.
