Pushy Parker (the child genius) Is a precocious child employed by the Civil Service to oversee the entire goings on in the impossible laboratory. Pushy Parker is obeyed without question by the rest of the characters; there is quite simply no... higher ...authority. Pushy is little more than child genius tiny bureaucratic dictator who speaks with a slight lisp and a thumb in her mouth. Along side Neil Nevers she co-hosts the show pouring scorn all its imbecilic inhabitants and their misguided pursuit of higher knowledge. Miss Parker is remarkably cynical for her slight years.
Neil Nevers (The scientist) Is the show's central narrator. Nevers has a calm, confident Attenborough tone but sometimes makes little or no sense. He speaks in pointed psychobabble as if he is addressing small minds with very big ideas. Nevers is a highly decorated scientist and globe trotting lecturer, his job is to go over people's heads while quietly losing his own mind.
Doctor Yes (The doctor) Is a thrill seeking zooologist with a booming Brian Blessed style voice. The missing link between David Bellamy and Anthony Worrall Thomson and a heady fusion of Fred Dibnah and an L.A sex doctor. Yes is an optimistic fatherly Santa figure but is often ruled by his baser instincts. He goes about his daily business with a great amount of passion and absolute confidence in his own actions. Like Gillian McKeith, whether or not he is a real Doctor is always in some doubt.
Chang Lee Ping (The magician) Is a mischievous magician and nymphomaniac. He speaks broken English in a babyish Chinese staccato. Flipping from sadistic cartoon villain to shakey pussycat Chang Lee is like the narrator from the 70s TV series, Monkey, speaking in riddles but with an air of the profoundly profound!
Father Black Wright (The holy man) Is a madcap, Irish, Frank Drevon-style man of the cloth. His complacency during experiments gives him a loveable presence. He's a member of the team because it's assumed having some kind of holy man close during major events may be useful, however he is completely incompetent. Black Wright usually comes across like Terry Wogan at his most knackered (Children in Need at 3 in the morning) Wright takes his ten commandments all the way up to 11.
Lizardboy (The mutant) Is the resulting aftermath of an experiment gone wrong. The intension was to turn a Bolton Wanders fan into a West Ham supporter and vice visa. But the experiment went tits up when the pod reversal booths failed to deliver a straight forward switch. Strangely both football supporters morphed into the same person. That person being the one and only Lizardboy: a freak of nature, a supporter of Bolton Wanders with a cockney accent, a reptilian tail and tall ear fins. This begs the question: was there an iguana involved? Lizardboy refers to everyone as "duckie" and is a submissive gimplike character kept in the cellar of the laboratory at the mercy of his masters.
Twinkie (The storytelling imp) Is an evil pixie fairy that collects stories from all around the world. Every time an impossible story is told we are sent to Twinkies cottage for an introduction on what we are about to receive. Twinkies cottage is a minute lilliput lane style ornament that sits on the office table of Doctor Yes. There is always a microphone stationed at the front gate waiting to record Twinkies next outburst. Twinkie speaks in a very high pitched voice with almost un-nerving jubilant enthusiasm seeming to spill over into giddy hysteria.
Impossible Guest star appearances: Throughout the series there a number of cameos of original characters such as Impossible's sponsor, the dry voiced mafia boss Ian kerchief, Jimmy the gardener, and hapless striker Bitter Tony. There's also a rich plethora of deranged celebrity impersonations including Humphrey Bogart, Orson Welles, Harrison Ford, James Stewart, Jacques Cousteau, Minnie Mouse and Dennis Hopper.
