According to the Weekly World News, the discovery of Bat Boy’s family tree on a genealogy chart recently stunned evolutionary scientists who used to think the famed imp was a pitiful, one-of-a-kind mutant - but now believe he belongs to a race of creatures who have interacted with humans for at least 400 years. In the tabloid’s account, the chart itself was written on vellum and found in the same Ozark Mountains cave where Dr. Ron Dillon, a biologist, rescued Bat Boy after he was trapped by a falling rock in 1992 (it should be noted, however, that the Ozark Mountains are nowhere near West Virginia).
