Card Trivia:XYZ-Dragon Cannon
- This is the cover card of Structure Deck: Kaiba Volume 2.
- This monster appears in the artworks of "Interdimensional Matter Translocator" and "Synchro Deflector".
- This monster has a stronger retrained counterpart: "XYZ-Hyper Dragon Cannon".
- This monster's original ATK (2800) is equal to the ATK of "X-Head Cannon" (1800) after applying the ATK-increasing effects of "Y-Dragon Head" (400) and "Z-Metal Tank" (600) equipped to it.
- This is the first monster that could be Special Summoned via Contact Fusion (even though that Special Summoning term didn't exist at the time).
- This is the only promotional card in the "Monster Figure Collection 3" (and in the three sets) that is not a Dragon monster.
- In the North American TCG, when this monster was released in Collectible Tins 2003, it was impossible to Summon because its Fusion Materials had not been printed until the release of Magician's Force one month later.
- This card's first and third OCG/TCG artworks are taken from Yu-Gi-Oh! Duel 254 (Duelist Duel 195): "Secret Plan to Call God!", the first from the panel showing this monster being Summoned, and the third from the panel where this monster is shown attacking "Big Shield Guardna".
- This card's second OCG/TCG artwork is taken from two separate scenes in the manga: the "X-Head Cannon" portion is taken from the same chapter, specifically from the panel showing "XY-Dragon Cannon" being Summoned, while the combined "Y-Dragon Head" and "Z-Metal Tank" portion is taken from Yu-Gi-Oh! Duel 255 (Duelist Duel 196): "Obelisk Strikes Back!", specifically from the panel showing "Interdimensional Matter Transporter" teleporting this monster (albeit with minor changes in detail for this second portion).
