Fib is the main antagonist in Larry-Boy and the Fib from Outer Space. At first he seems like a nice little alien, but Fibrilious Minimus can get to be a very very big problem. When he convinces someone to lie, he grows bigger. Only the truth can make him shrink.
- Some people consider fib to somewhat resemble a virus (a form of life with no cells that must invade or infect a cell to reproduce) or a microscopic single-celled creature. Particularly the rotavirus or a protozoan.
