- The flashing background seen in this card's artwork can also be seen further away in the artwork of "Junk Archer".
- The wording of the latter part of this card's effect is very similar to that of a Union monster except that it does not have the Union monster's limitation of one per monster, nor does it protect the equipped monster from destruction.
- This card's English name has become somewhat of a gag by the fan community. Since the monster is an autonomous gauntlet and machine as a sole monster, it could very well be an armored arm. In this context, "Armory Arm" becomes a pun.
