Card Trivia:Mermail Abyssgaios
- This monster appears in the artworks of "Abyss-strom" and "Fire King Sky Burn".
- According to Master Guide 4, this card was originally "Poseidra, the Atlantean Dragon", before being transformed by the bracelet seen in "Abyss-squall".[1]
- This is supported by how both the bottom of this monster's body resembles "Poseidra's", both of whom share the same Attribute (WATER), original ATK and DEF (2800/1600), and number of "stars" (7).
- Fittingly, this monster's silhouette also appears in the commercial of Realm of the Sea Emperor Structure Deck, the debut Structure Deck of "Poseidra".
- This card is based on Poseidon, the Greek god of the sea who is often depicted wielding his signature weapon, the trident.
- This card's name is based on the epithet of Poseidon, "Ennosigaios" (meaning "earth-shaker"), referencing how Poseidon is also the Greek god of earthquakes.
- Fittingly, this monster can be Summoned by using "Poseidra" as Xyz Material, who is also based on Poseidon.
- This card has a counterpart: "Mermail Abysstrite".
- Both cards' original ATK and DEF are an inversion of each other.
- Both cards are named after the Greek gods of the sea; in the case of "Abysstrite", she is named after Amphitrite, the wife of Poseidon.
