Captain Caveman, or "Cavey" for short (voiced by Mel Blanc), is the protagonist of the show, billed as "the world's first superhero." He is a caveman who is millennia old (his exact age is never disclosed, although in an episode he is carded by a doorman who is unsure Cavey is old enough to let in, to which Captain Caveman responds, "I'll be 2 million next month."). He can pull various objects from his long body hair that covers his body except for his nose, arms, and legs. He can also fly, but his flying power always seems to fail him at the worst possible moment. Sometimes he would attribute this mishap to an energy shortage ("Uh oh! Bad time for energy crisis." CRASH!), which was a reference to the gasoline rationing shortages of the late 1970s. He speaks in stereotypical "caveman-talk", replacing subject pronouns with their object equivalents and dropping articles such as "the" (for example, "Me know where bad guys are hiding."), and often mumbles the nonsense phrase "unga bunga". He also has a bad habit of occasionally eating large non-food objects in one gulp (i.e. bicycles, TV sets, safes, table lamps), and the Teen Angels occasionally have to stop him from eating potential clues that will help them to solve the mystery. Despite this, Cavey is ultimately loyal to them and he is very capable capturing culprits.
