This is a list of allusions to pop culture found throughout ǝnígmǝ.

  • The design of the skull and symbol of ǝnígmǝ is based off that of late American murderer and body snatcher Ed Gein.
  • Sumio's "Mayday" catchphrase and some of his speech from page 10 are derived from the lyrics of Japanese hard rock band B'z's song Mayday!.
