The Missing Link is a 20,000-year-old fish/ape hybrid who acts like a jock, but is really just out of shape in Monsters vs Aliens. He was frozen in the last Ice Age and was thawed out by scientists. He was captured in 1961 but when he escaped he went back to his old lagoon and found it being turned into a resort and he started terrorizing the tourists. He is even a father figure to his monster friend Insectosaurus.
