Quotes (voice by Hibiku Yamamura)

- "Analysing <...Spark Doll name...>" (<...Spark Doll name...>解析 <...Spark Doll name...>Kaiseki) - Voice announcement when scanning Spark Doll.
- "Activating Gao Dection, analysing <...Spark Doll...>, analysis completed!" (ガオディクション起動します, <...Spark Doll...>解析中, 解析完了しました! Gao Dikushion Kido Shimasu, <...Spark Doll...>Kaisekishu, Kaiseki Kanryo Shimashita!) - Scanning the Spark Doll's Gaodiction.

- The X Devizer is unique in that its creation took place on screen. All previous transformation devices (save Esplender) were created before their initial appearance.
- Of all the voiced transformation devices (the Spark Devices and the Victory Lancer), the X Devizer is the first one with a female voice.
- Keeping with the MonsArmor themes being based on Digimon species from the Digimon franchise, the X Devizer is likely based on D-Techtors (ja:D-Scanners) from Digimon Frontier, where both items are originally regular communicator devices (Xio Devizer for X, cellphones for Frontier) until they are upgraded to contain the warrior the user would turn into.
- Due to a design flaw in the toy for the X Devizer, certain Spark Dolls cannot be scanned. Among them are Dinosaur Tank, Twin Tail, and Tsurugi Demaaga.
