The Bunnyman is a figure of urban legend in Fairfax County, Virginia. He’s said to hang out around the Colchester Overpass. Two incidents have formed the legend, both occurring in 1970. A couple in a car were seen being accosted by a man in a white bunny costume smashing their car window, screaming about trespassing. Also, a security guard once approached a man standing on the porch of one of the unfinished homes on the site. The man was wearing a bunny costume and holding a long-handled axe, and he began chopping at the porch while complaining about trespassers. Nothing further was ever discovered about these incidents, which are creepy enough on their own.
