|Family||Cavey, Jr. (son)|
Captain Caveman is the main character, a caveman who is thousands of years old (his exact age is never disclosed). The Teen Angels often call him "Cavey."
Captain Caveman can pull various objects from his body hair. He can also fly, but his flying power always seems to fail him at the worst possible moment. 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.
