Card Trivia:Armory Arm
- This monster appears in the artwork of "Synchro Forceback".
- This card is the first Machine-Type Synchro Monster and the first Level 4 Synchro Monster.
- This card's English name is a pun: this monster is an armored arm that can act autonomously and as a weapon.
- The wording of this card's first effect is very similar to that of a Union Monster, except that it is not limited to one per monster, nor does it protect the equipped monster from destruction.
- In the Yu-Gi-Oh! 5D's anime, this was the only Synchro Monster that Yusei Fudo did not have a Synchro Summon chant for.
