Behind the Scenes

Concept Art

  • This Minosaur is based on Arachne, a talented mortal weaver who challenged Athena (goddess of wisdom and crafts) to a weaving contest which resulted in Arachne being transformed into a spider. This makes it the second Minosaur based on a female mythological creature after the Medusa Minosaur.
  • The Arachne Minosaur's EXP value (335) is a Goroawase pun. It could be read as mi (3) - sa (3) - ko (5), which is the name of its host, Misako Iimura.
  • The Arachne Minosaur is the second female Minosaur to be shown in the show (the first being the Medusa Minosaur).
  • This Minosaur's EXP shares the same three numbers for transforming into a Megaranger via the Degitaizer. Notably, Megarangers' story is also set in a school.
  • Arachne Minosaur's catchphrase, "Rururu", is referred as the sound used to call a fox in the drama "Kita no Kuni Kara".
  • The Arachne theme brings to mind of ArachneIcon-crosswiki.png from Kamen Rider WizardIcon-crosswiki.png.
