Card Trivia:Armory Arm
- The flashing background seen in this card's artwork can also be seen further away in "Junk Archer"'s artwork.
- This card's effect gives the monster it's equipped to an effect similar to that of "Elemental Hero Flame Wingman", "Elemental Hero Shining Flare Wingman" and "Neos Force".
- The burn damage of this card somewhat resembles "Junk Barrage" and "Nitro Unit".
- This card's art bears a resemblance to the "Armor Monsters".
- 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.
- This card's English name has become somewhat of a gag by the fan community. Since the card 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 card is the third lowest level Synchro Monster, the second being "Turbo Cannon" (Level 3), and the first being "Formula Synchron" (Level 2).
- This is the only Synchro Monster in Yusei Fudo's deck that he does not have a chant for when performing its Synchro Summon.
