Spring-heeled Jack, “the Terror of London,” is a well-known monstrous villain of Victorian urban legend. Though generally human in appearance, Spring-heeled Jack is said to have demonic characteristics such as bulbous glowing eyes, long, sharp claws of metal, and sometimes even horns. He was often seen in England and Scotland in a bat-like, black winged cloak and a tight suit of black and white oilskin, not unlike a twentieth-century comic book character’s costume. Reports of Spring-heeled Jack speaking, or indeed making any sound, are rare, and it is possible he is mute, though there have been reports of victims hearing fiendish laughter. Another unnatural characteristic commonly attributed to Jack is his ability to spit blue flame. Spring-heeled Jack’s most famous attribute, though, is his ability to escape capture by leaping over tall gates and walls.
