- This card is based on Scylla, a sea monster from Greek Mythology featured in both the stories of Odysseus and the Argonauts. She made her lair on one side of a narrow straight, opposite another sea monster named Charybdis. Scylla had six serpentine heads and a lower body that consisted of twelve fierce dogs. If a ship ventured too close to her, six of its crewmen would likely fall victim to her ravenous appetite. If a ship tried to avoid her by steering away, it would likely fall victim to Charybdis. The popular phrase "between a rock and a hard place" is attributed to these two monsters.
- Though stated as a Reptile-Type monster, this card is not serpentine like the rest of the "Reptilianne" monsters.
- This card's effect is almost the same as the effect of "Goyo Guardian".
- This card is featured in the artwork of "Viper's Rebirth".
