    • By coincidence, his surname Kayn resembles:
      • Biblical Cain, from Semitic root q-y-n "smith"[2] < "spear" < "reed" *qanay.[3]
      • Irish surname Kane, Anglicized from Gaelic Ó Catháin, from Proto-Celtic *katus "fight, battle".[4]

    Rhaast: "Zed's dead baby, Zed's dead." quotes Pulp Fiction.
    Kayn OriginalCircle Rhaast "And then there were four? I think." is a reference to an old minstrel song which was made famous in Agatha Christie's "And Then There Were None"*, which counts down 10 children dying one by one. After the sixth child dies, four remain, hence "and then there were four".


Kayn OriginalCircle Original Kayn
  • His appearance was inspired by Amon from the manga and anime series Devilman.
    • The method in which Darkin possess human bodies is similar to how Demons possess humans in Devilman. Humans in both instances can also overpower the demon/darkin and use their power as their own.
  • His appearance pays homage to both Dante and Vergil from Devil May Cry, with Vergil's Shadow Assassin OriginalSquare bluish color scheme and Dante's casual & confident attitude that he can subdue any demonic weapon to his will.
  • Kayn may be a possible reference to Ling Yao, a character from the anime Fullmetal Alchemist: Brotherhood. Both characters share similarities in that a superhuman entity reside in them which vies for control of their bodies (Rhaast, a Darkin inside Kayn and Greed, a Homunculus inside Ling Yao). Moreover, Kayn shares quite a lot of similarities in character design with Ling Yao.
  • Kayn could also similar to Masane Amaha, a character from the anime Witchblade (An adaptation of the comics of the same name). Both wield weapons that are sentient in nature and try to take control of their bodies (Kayn's Scythe contains Rhaast, and Masane's gauntlet contains an unnamed entity), as well as both of them possessing supernatural powers.
Kayn SoulhunterCircle Soulhunter Kayn
  • The Shadow Assassin form seems to reference the Abyss Watchers from Dark Souls 3.

  • In the Russian localization, he is called 'Showerhunter Kayn' due to a naming error.[9]
