In the not too distant future, the Earth finds itself under attack from Queen Zelda, a blood-thirsty android who, along with her fiendish family has established a base on Mars. Battling against the ultimate annihilation of mankind are the Terrahawks, an intrepid band of heroes led by the clone, Doctor Tiger Ninestein. The Terrahawks defence grows all the more desperate, as a terrifying new enemy joins forces with Zelda; and together with an army of new monsters, the Earth doesn't stand a chance!
