At the moment the potentially fatal shot is fired, the action freezes, and the narrator asks dramatically if Batfink will survive.

When not fighting crime, Batfink lives in a split-level cave, though he also has a direct video link to the Chief's office in case his help is needed.

The literal spelled-out appearance of an onomatopœia was a running gag not limited to the supersonic sonar radar; in one episode, Hugo A-Go-Go invented a tickling stick that tickles its adversaries into submission, which sent out the words "Kitchy Koo" to do the deed on Batfink (the episode ended with Batfink slicing the K's off to create the far more irritating, but less distracting, "Itchy Oo").

Batfink rides in a customized pink car resembling a Volkswagen Beetle with scalloped rear fins and bat-winged red "B" emblems on the doors and hood.

Called the "Battillac" (rhymes with "Cadillac"), the car is outfitted with a sun roof and many defensive devices, and is resistant to collision damage and energy weapons.

Kara "Karate" Te (voiced by Len Maxwell) is a gi-clad martial arts expert and Batfink's oafish sidekick who drives the Battillac.

Karate is a direct send-up of Kato, the Green Hornet's companion, but his hulking size is inspired by the Bond villain Oddjob.

[citation needed] Also, like in The Green Hornet, when both characters are in the car, Karate is the driver, while Batfink rides in the back seat.

General Professor Hugo "Jerkules" A-Go-Go (voiced by Frank Buxton) is the wild-haired smocked main villain of the series.

Hugo A-Go-Go is using an Indian (i.e., Native American) motif for his latest crime spree "because I don't look good as a cowboy!"

Hugo A-Go-Go is using a "goldstinger" – a wand that instantly encases people and things in gold plate – to turn the heroes into immobile statues.

Hugo A-Go-Go has invented a mechanical bride to help him commit crimes; the climax of the action takes place at Niagara Falls.

According to Dave Mackey's Batfink site, a two-part political message is concealed in two episodes, disguised as sped-up gibberish.

Mackey translates the message as follows: The cartoon was produced at Hal Seeger Studios, in New York City, and at Bill Ackerman Productions in Midland Park, New Jersey.

The Batfink series was very popular in the UK, becoming a cult series like the later Danger Mouse, and from 1967 onwards, it was shown at least once every year on UK terrestrial television until 1983, initially on the BBC network, where it was allocated an early evening slot just before the BBC News, and latterly as part of Children's ITV; it subsequently reappeared in 1986 on the ITV Saturday morning magazine show Get Fresh.

In the early 1990s, it was repeated again as part of TV-am's Wide Awake Club/Wacaday series; after Wacaday finished in 1992, Batfink was consigned to the vaults in the UK for the next twelve years.
