Card Trivia:Tellarknight Ptolemaeus
- This monster appears in the artwork of "Zefra Divine Strike".
- According to the Master Guide 5 card storylines, this monster is an upgraded form of "Constellar Sombre" after fusing with "Stellarknight Constellar Diamond" and the rest of the remaining "tellarknights".
- This card is named after the astronomer Ptolemy and is possibly based on his geocentric model of the universe, which appears in the background of its artwork.
- This card's cost of detaching 7 Xyz Materials in order to use its turn skipping effect may be a reference to the 7 spheres that orbit Earth in Ptolemy's model: the Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn.
- This is the first "tellarknight" monster to be Forbidden.
- This card has a watered-down counterpart: "Darktellarknight Batlamyus".
- This card's Attribute (LIGHT) is the opposite of the Attribute (DARK) of "Batlamyus".
- This card's ATK/DEF (550/2600) are inverted with the ATK/DEF (2600/550) of "Batlamyus"
- Both cards are named after Ptolemy.
- Both cards have effects that require 7 other cards for the activation.
- According to the Master Guide 5 card storylines, "Batlamyus" is the upgraded form of "Gem-Knight Lapis", the twin sister of "Ptolemaeus" ("Gem-Knight Lazuli").
- As its second effect requires 7 Xyz Materials to be detached to activate it, this card is the Xyz Monster that requires the largest defined number of Xyz Materials to be detached from it to activate its effect.
