The Missing Link, also known as simply "Link", is a 20,000-year-old fish/ape like creature who acts like a jock, but is really just out of shape, in the tv series Link has gotten back in shape and started working out. He was frozen in the last Ice Age and thawed out by scientists. He was captured in 1961. When he escaped, he went back to his old lagoon, found it had been turned into a resort, and started terrorizing the tourists. He is the only monster who can understand Insectosaurus, who thinks Link is his father! The Missing Link is voiced by Will Arnett in the film & by Diedrich Bader in the TV series.
