The Impossibles

Each member of the Impossibles had a specific and visual superpower:

• Coil-Man (voiced by Hal Smith) - Short, barrel-chested and sporting a mod haircut, blond "Coily" could transform his arms and legs into impossibly stretchable or coiled springs, allowing him to bounce to avoid attacks, deliver long-range punches, or drill through walls. Coil-Man usually drove the Impossi-jet, and his guitar contained a small TV receiver through which "Big D" (voiced by Paul Frees, who also served as the voice-over narrator in almost every episode) could contact the group and deliver orders (Big D used Multi Man's guitar in "The Fiendish Dr Futuro," "Beamatron" and "The Diabolical Dauber"). Because of his presumably metal coils, Coily could be held in place by a super magnet, but could also conduct heat or electricity with his coils. He hid in a closet disguised as a wire coat hanger, further implying that he was at least partially made of metal. Coil-Man's costume was purple and blue and included a purple mask and a cowl crested by a triangular fin.
• Fluid-Man (voiced by Paul Frees) - Dark-haired Fluid-Man, a.k.a. "Fluey", could morph parts (or all) of his body into a liquid form, allowing him to, for example, sneak up on an enemy though a water faucet. He could also vaporize himself into a cloud or storm, but could be soaked up and trapped by a sponge ("Televisatron" and "Return of the Spinner"), or frozen solid inside a block of ice ("Not So Nice Mr. Ice"). Fluid-Man's costume resembled a lime green wetsuit complete with diver's mask and swimfins. Fluey's speaking style indicated that he was the beatnik of the group.
• Multi-Man (voiced by Don Messick) - Multi-Man, a.k.a. "Multi", could create infinite duplicates of himself that were often destroyed, leaving only the original behind. His duplicates rarely, if ever, functioned independently, and were often used as camouflage, a bluff, for extra strength or transportation (he could fly by continuously creating replicas above himself). When duplicating himself, he could push tons of rocks out of the way or crack a block of solid concrete (in which he and the others were entombed). The character had shaggy orange hair that covered his eyes (his eyes, in fact, are never seen) and he usually holds a shield for apparently decorative reasons. Multi showed the ability to repel bullets with his bare hand ("Fero, the Fiendish Fiddler"). Multi-Man's angular, red and black costume resembled a stylized 'M', and included a short, triangular red cape. Favorite saying: "You got them all except the original." Multi bore a resemblance to the identical members of the singing group "The Way Outs" from The Flintstones.

Each episode usually began with the villain pulling off an improbable caper while The Impossibles were busy performing across town. The team is called into action by their chief "Big D" (voiced by Paul Frees). After a series of funny superpowered forays, the Impossibles capture the villain and return to finish their concert.

Villains

The Impossibles faced many bizarre villains. All villains were defeated in a timely manner and justice was always served.

The following villains have appeared more than once:

• Spinner (voiced by Hal Smith) - Has spider-based powers, specifically web spinning. He first appeared when he stole a million dollar tiara. Spinner later returned when he stole a poodle by the name of "Little Miss Muffet".

In his first appearance, Paper Doll Man stole most of the top secret plans from the Pentagon and had to return there to get Plan X. In his second appearance, Paper Doll Man was robbing hotels. This time, he was defeated when he accidentally flew into a linotype machine that was printing newspapers.
• Professor Stretch (voiced by Paul Frees) - Super-stretchy with elasticity powers. He appeared twice. The first time was when he sabotaged a tank by using powder from a shaker that turns anything into rubber and in the end we see him used as a basketball.

• Inflator (voiced by Hal Smith) - A villain who attacks places with giant balloons that he creates using a special ray-gun. He has served his time and is now a balloon vendor selling his balloons to children. He claims his reason for villainy was due to monetary inflation.
• Billy the Kidder (voiced by Hal Smith) - A futuristic western outlaw that rides a robotic horse who wanted to rob the Mint. After serving his time, he becomes a rodeo star where he is uncomfortable riding actual horses.

An ad for the Saturday morning cartoon lineup in comic books of the time referred to "the Bubbler", "Bratfink", and "The Sponge".

The Impossibles episodes were written by Michael Maltese, who is known mostly for his work with director Chuck Jones.
