Rocket Robin Hood leads his "Merry Men", including the strong, dimwitted, and likeable Little John; consummate overeater Friar Tuck (who designs all the Merry Men's weaponry); Robin's two-fisted, red-headed cousin Will Scarlet; Robin's plucky girlfriend Maid Marian; his sharp-witted right-hand man Alan-a-Dale; the scrawny, feisty camp cook Giles (a reformed crook and Gabby Hayes type); and other characters from the classic story of Robin Hood. They live in "the astonishing year 3000" on New Sherwood Forest Asteroid, and are determined to foil the despotic plans of Prince John and his bumbling lackey, the Sheriff of N.O.T.T. (National Outer-space Terrestrial Territories), and other villains such as Dr. Medulla, Manta, Nocturne, and the Warlord of Saturn. Rocket Robin Hood and his people fly in spaceships and use weapons such as "electro-quarterstaffs". Each 22 minute episode is divided into three segments, with cliffhangers between the first and second part, and the second and third part. All episodes feature short vignettes of the various characters. A male chorus sang the opening and the closing themes for each of the three seasons of the cartoons, in the style of the old English ballads.
