The Big Knights

Sir Boris: The finest swordsman in the world. Noble, brave, honourable and chivalrous, and while not nearly as stupid as his brother Sir Morris, not terribly bright either. He is clad in silver armour.
Sir Morris: Not the finest swordsman in the world, but the most enthusiastic. He is incredibly stupid, once believing that breakfast was magically made by the plates. His general method of dealing with problems is by hitting them with maximum force. He wears glasses, and bronze armour.
Sir Horace: Sir Boris' loyal hound, clad in armour. He is a fine tracker dog, once tracking a flying crow that had stolen a golden key with his smell alone.
Sir Doris: Sir Morris' pet hamster, likewise clad in plate armour. She has an insatiable appetite and will eat just about anything irrespective of its size or edibility, including Morris' fingers, a bicycle and man-eating plants.
Mrs. Ethel Minion: The knights' housekeeper and de facto nanny, without whom they find survival rather difficult. She takes a matronly view toward her outsize charges. She seems to enjoy the housework.
King Otto: King of Borovia, and a single parent. His occasional attempts to modernise his country often fail disastrously at the well-meaning hands of the Big Knights, as well as his desire to cut costs in most situations. He is insipid and dull-headed. He has two daughters, Princess Lucy and Princess Loretta, who manipulate him mercilessly.
Princesses Lucy and Loretta: King Otto's twin daughters. Enthusiastic, naive and oblivious to danger and trouble. They absolutely love adventure and are keen admirers of the Big Knights.
Wizard Zabobon: Wizard and advisor to King Otto. He is very old and it appears that he has never once thought of personal hygiene. He is an incompetent wizard but sometimes offers good advice, which the king ignores.
Professor von Proton: The brain behind Borovia's drive to modernisation, he is also totally insane. He once covered the whole country in pig manure as a result of a quest for cheap renewable power.
Queen Melissa: Queen of Moridia and incredibly wealthy. According to the programme website, she is rumoured to have been married to King Otto at some stage, but this is not mentioned in the show itself. Her fabulous wealth is a constant source of envy to King Otto.
Sorceress Abigail: Cleaner, brighter, female version of Zabobon employed by Queen Melissa.
Sir Kiftsgate: The apparent leader of a new breed of knights who know the difference between bowing to a Duke and an Earl but are totally useless at traditional knightly pastimes such as slaying dragons and ogres.
