Card Trivia:Number XX: Utopic Dark Infinity
- This is the first "Number" monster to debut in a manga outside of Yu-Gi-Oh! ZEXAL - specifically, debuting in the Yu-Gi-Oh! ARC-V manga.
- This is the first "Number" monster to lack an actual number in its name.
- Similar to other "Number" monsters that have their number depicted somewhere on their bodies/accessories, this monster has two "X" on its shield (depicted in the Barian glyph style), which reflects its own "Number".
- The presence of these Barian glyphs implies that this monster has some unknown connection with the Barian World, possibly originating from there.
- This monster also has large X on its chest reminiscent of the stylized X in the ZEXAL logo.
- Similar to other "Number" monsters that have their number depicted somewhere on their bodies/accessories, this monster has two "X" on its shield (depicted in the Barian glyph style), which reflects its own "Number".
- This monster has the highest DEF (4000) of all Xyz Monsters (tied with "CXyz Skypalace Babylon", "Number 81: Superdreadnought Rail Cannon Super Dora", and "Superdreadnought Rail Cannon Juggernaut Liebe").
- In the manga, this card has its Rank strangely aligned to the right side of this card instead of its left side.
- This card's OCG/TCG artwork is taken from Yu-Gi-Oh! ARC-V Scale 33: "Eve's True Skills!!", specifically from the panel showing this monster being Summoned, albeit with its head facing towards the reader (which is taken from the same chapter in the panel showing this monster, "Phantasm Emperor Trilojig", and "Timelord Progenitor Vorpgate" together).
