Orthrus is a two-headed dog from Greek mythology. Vulcan is the Roman god of fire and forge, although he does have a Greek counterpart in Hephaestus.
- The phrase that's said in the transformation is "Awakening the instincts of two beasts long lost" referring to the Japanese/Honshuu Wolf and the Hokkaido Wolf native Japanese wolf species, both extinct.
The "highest mountain of rock" mentioned in Ark-Scorpion's transformation is a reference to his stunt actor Takaiwa Seiji, whose family name means "tall rock".
Goof: During Aruto's transformation into Zero-Two, Ark's evil sound can be briefly heard when the Zero-Two symbol closes in to finish the transformation sequence.
