Card Trivia:ZW - Leo Arms
- "Ultimate Leo Utopia Ray" appears in this card's artwork.
- This card share some traits with "ZW - Dragonic Halberd".
- Both are Rank 5 Xyz Monsters with 3000 ATK and 1200 DEF, although "Leo Arms" is a LIGHT monster, while "Dragonic Halberd" is a DARK monster.
- Both have the highest ATK among all Rank 5 Monster Cards that require only 2 Xyz Materials.
- Both have similar color schemes of red and yellow, a reference to ZEXAL's armor colors.
- When equipped to a "Utopia" monster, both give the most amount of ATK among the "ZW -" monsters.
- When equipped to "Number C39: Utopia Ray", both form what is called an "Equipped Union": "Ultimate Leo Utopia Ray" for "Leo Arms" and "Ultimate Dragonic Utopia Ray" for "Dragonic Halberd".
- "Ultimate Leo Utopia Ray" bears this monster's armor form.
- This card's armor is very similar to Yuma's armor while he is in ZEXAL Morph.
- This is the only anime card that grants a monster the ability to attack outside the Battle Phase.
- Originally, this monster was called "ZEXAL Weapon - Dragonic Halberd" (
ＺＷ －弩級兵装竜王戟 Zearu Wepon - Doragonikku Harubādo) and was stated to be a DARK monster on a TV Tokyo website post. The post was later updated to the current name and Attribute. Over eight years later, the same exact name and Attribute were reused for another "ZW -" Xyz Monster in Lightning Overdrive.
