The word "cipher" in this card's name could refer to the word's use as a symbol for the numberzero, which in turn could reference either the "Number" archetype from Yu-Gi-Oh! ZEXAL or Kite's role as a Number Hunter in said series. It could also reflect that this dragon is no longer a "Number", nor does it has anything to do with "Number".
In addition, the "光波" used for "Cipher" translates to "light wave", mimicking how a photon is a light-carrying particle.
The attack name of this monster is also inherited from the "Number 107: Galaxy-Eyes Tachyon Dragon" (...of Annihilation) and "Galaxy-Eyes Photon Dragon" (Photon Stream..), but change the word "Photon" to "Cipher", to match the name "Galaxy-Eyes Cipher Dragon".
This is the first "Galaxy-Eyes" monster in the anime that doesn't appear in a sealed form when Summoned.
Like its ZEXAL counterpart, this dragon re-uses the roars of "Stardust Dragon".
