Sir Batfink (voiced by Frank Buxton) is a superpowered anthropomorphic grey cyborg bat in a yellow costume with a big red "B" on the chest and red gauntlets and boots.[5] He uses his supersonic sonar radar and black metallic wings to fight crime. 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.<br /><br />Batfink's "supersonic sonar radar" is a super-powered version of a bat's echolocation, used to locate prey. Batfink's power takes the form of the letters of the word "BEEP", either once or twice emanating from his mouth. The letters are anthropomorphic and sentient and can fly wherever Batfink needs them to go – accompanied by a distinctive beeping noise. His catchphrase during that time is "My supersonic sonar radar will help me!" Whenever Batfink said those words, he would say it through the open sun roof of the Battilac car, while it was not in motion. The letters can see; feel fear; evade capture; and report back to Batfink on what they have seen. In one episode, the "BEEP" is ambushed and beaten up. The "BEEP" also gets confused, misdirected, and lost, leaving Batfink to rely on other means to spy upon the episode's villain. Once, when the "BEEP" is sent to investigate Queenie Bee and her swarm of villainous bees, it returns with the letters "EEP" swollen with bee stings. When Karate asks Batfink: "How come they just stung the EEP?" Batfink replies: "Because a bee would never harm another 'B.' But a 'B' will tell on another bee – Queenie Bee is in THERE!" 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").
