Card Trivia:Galaxy-Eyes Photon Dragon
- This is the cover card of Photon Shockwave, and is also one of the cover cards of Duelist Pack: Kite, Collectible Tins 2011 Wave 2 and 25th Anniversary Tin: Dueling Heroes.
- This is the first non-Extra Deck Booster Pack cover card since Crimson Crisis.

- This is the signature card of Kite Tenjo in Yu-Gi-Oh! ZEXAL.
- This monster has several forms/evolutions:
- "Galaxy-Eyes Afterglow Dragon" as a retrained version of this monster, as indicated by its identical stats and identical body (with the exception of its color scheme).
- "Galaxy-Eyes Cipher Dragon" as this monster's "Cipher" counterpart, being the ace monster used by the Yu-Gi-Oh! ARC-V version of Kite Tenjo.
- "Galaxy-Eyes Cloudragon", as a baby form of this monster (as indicated by its appearance and effect).
- "Galaxy-Eyes Full Armor Photon Dragon", as an Xyz Monster evolution of "Galaxy-Eyes Photon Dragon", by using 2 Equip Cards as its Xyz Material.
- "Neo Galaxy-Eyes Photon Dragon", an Xyz Monster evolution created with the power of the Barian World, via Hart Tenjo.
- "Number 62: Galaxy-Eyes Prime Photon Dragon" as its true form, created with the power of the Astral World.
- "Galaxy-Eyes Solflare Dragon", as a Link Monster version of this monster.
- "Galaxy Dragon" is a monster that greatly resembles this one; in the Yu-Gi-Oh! ZEXAL manga, Hishakaku considered it as "a monster designed to combat Galaxy-Eyes," as indicated by its manga effect and the effect of "Dragon Buster".
- This card's name follows the same pattern as "Blue-Eyes White Dragon" and "Red-Eyes Black Dragon".
- This monster's attack name, "Photon Stream of Destruction", is also very similar, both in name and appearance, to "Burst Stream of Destruction", the attack of "Blue-Eyes White Dragon".
- True to its name, this monster's eyes have a galaxy-like pattern.
- This card has the same ATK (3000) as "Blue-Eyes White Dragon", "Armed Dragon LV10", "Red Dragon Archfiend", "D/D/D Doom King Armageddon", and "Borreload Dragon" the signature cards of Seto Kaiba, Chazz Princeton, Jack Atlas, Kite Tenjo, Declan Akaba, and Roken Kogami the rivals in the other anime series based on Master Duel.
- Like "Blue-Eyes Ultimate Dragon", this card's stronger form, "Neo Galaxy-Eyes Photon Dragon", also has 3 heads and 4500 ATK;
- Also, this card has the same DEF, Level, Attribute and Type as "Blue-Eyes White Dragon";
- Furthering its similarities to "Red Dragon Archfiend", in ZEXAL episode 24, Kite calls this card "Ore no tamashii" (lit. "My soul"), which is similar to what Jack Atlas calls "Red Dragon Archfiend" in the Japanese version of 5D's.
- Another similarity to "Red Dragon Archfiend" and "Blue-Eyes White Dragon", "Galaxy-Eyes Photon Dragon" is facing the opposite way in its artwork to "Number 39: Utopia", similar to how "Blue-Eyes" faces the opposite way to "Dark Magician" and how "Red Dragon Archfiend" faces the opposite way to "Stardust Dragon".
- In the anime, after this monster is Summoned, its body remains its basic dull, purple color until it steals Xyz Materials, which then makes the scales and jewels on its body light up and glow brightly.
- In Yu-Gi-Oh! Duel Links, its in-game model depicts it with green skin instead.
- According to Astral, this monster has light dwelling within it similar to his own world. In the international dub, Astral says he had seen the dragon before. This may be why it has a rivalry with "Number 107: Galaxy-Eyes Tachyon Dragon", which appears to be a monster from Barian World.
- In both the anime and the manga, when this card is Summoned, it appears as a four-sided star that absorbs all light around it, and then takes the form of this monster.
- Since its second appearance in the anime, this monster has been reusing the roar of "Stardust Dragon", along with the roars of "Shooting Star Dragon" and "Shooting Quasar Dragon".
