- This card resembles Mr. Hyde from Robert Louis Stevenson's Dr. Jekyll and Mr. Hyde. Mr. Hyde is the evil alter ego of Dr. Jekyll and represents the latter's inner evilness. Mr. Hyde is often portrayed with a monstrous look that resembles a ghoul. This card might reference the character, as Yuya Sakaki first Summoned this monster when Zarc was awakening from inside Yuya's body.
- This is the first "Performapal" monster to be portrayed as an "evil" creature.
- "Gatling Ghoul's" cylinder and skin color resemble "Performapal Fugolem's", the card that was used as a Fusion Material when this card was first Summoned in the anime.
