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.
This is the only Synchro Monster in Yusei's Deck that he does not have a chant for when performing its Synchro Summon.
