Behind the scenes



  • Xibalba's name came from Xibalba, the name of the underworld in Mayan mythology.
  • Considering Xibalba is a Gamma Ultima and his Gamma Hole shape, he might be a relative of the Gamma Royal Family, or simply a promoted Gamma Superior by said family.
  • Xibalba's situation mirrors Gamma A from Kamen Rider × Kamen Rider Ghost & Drive: Super Movie Wars Genesis in that both are Gamma who are not shown to adopt human forms and appear exclusively in spin-off material outside the Ghost series, yet are the first seen examples of an advanced Gamma form which is later shown to be used in the series by Gamma characters with human forms. Xibalba being first known example of the Gamma Ultima form which is later assumed by Adel, while Gamma A is the first known example of the Gamma Superior form which is later assumed by Jabel (and then Igor).
