Sphinx was a safecracker and the accomplice of Crewy Lou. He was bald and typically wore eyeglasses and a beret and carried a cane.

At some point in the past, Sphinx had been rendered mute after accidentally drinking poison he had prepared for one of his enemies. He communicated with Crewy Lou by writing notes with a pencil he always kept with him. He also had a special acid that dissolved his notes so they couldn't be used as evidence.

Sphinx was killed by The King’s men after The King was shot by Crewy Lou.
