Card Trivia:Galaxy Serpent
- This card is the first "Galaxy" card that was first released only in the TCG.
- This is also the first "Galaxy" Tuner monster and the first "Galaxy" Normal Monster to be released.
- A constellation appears on this monster's body - specifically, what appears to be an adjusted version of the Hydra constellation.
- This, combined with the phrase "Sea of Stars" in this card's descriptive text, lends support to the idea that "serpent" in this card's name is taken from "sea serpent".
