Card Trivia:Ice Beast Zerofyne
- This card's Japanese name, "Sub-Zero Bird Beast Sylphine" is a portmanteau of "sylph" and "undine", both of them mythological elemental beings.
- This monster's feminine appearance and WATER Attribute is based on how the undine is the nymph of water that takes the form of a woman.
- This monster's Winged Beast Type reflects how the sylph is based on how the nymphs are the invisible spirits of wind, where the WIND Attribute is commonly associated with bird-themed monsters.
- This card's TCG name is a portmanteau of "zero" and "undine", referencing absolute zero, the lowest value that temperature can reach at 0 kelvin or Rankine, where an atom's movement stops, and any known matter becomes its solid form. This value is commonly measured at −273.15° Celsius and -459.67° Fahrenheit.
