Spring-heeled Jack was described by people who claimed to have seen him as having a terrifying and frightful appearance, with diabolical physiognomy, clawed hands, and eyes that "resembled red balls of fire". One report claimed that, beneath a black cloak, he wore a helmet and a tight-fitting white garment like an oilskin. a "Devil-like" aspect. Others said he was tall and thin, with the appearance of a gentleman. Several reports mention that he could breathe out blue fire.
