Sinister Sphinx

The Sinister Sphinx was a beautiful female assassin who began to target prominent women for murder and blackmail. She killed these women and left behind her calling card, a sphinx figurine. The plan was to establish a ruthless reputation so that, in future abductions, the loved ones would pay as quickly as possible. The Sphinx’s weapon of choice was a knife. She drove a souped-up roadster with a sphinx figure on the hood. The murder spree brought her to the attention of the Blue Beetle, his partner Mike, and his girlfriend Joan Mason. Joan came up with the idea to create a fake crime scene and planting a figurine, figuring the Sphinx’s pride would get the better of her and confront the copycat. Blue Beetle apprehended the Sphinx.
