- This monster is the cover card for Galactic Overlord.
- This card is an upgraded version of "Galaxy-Eyes Photon Dragon".
- Just as "Galaxy-Eyes Photon Dragon" is very similar to "Number 107: Galaxy-Eyes Tachyon Dragon" & "Galaxy-Eyes Cipher Dragon", this card shares many similarities with "Number C107: Neo Galaxy-Eyes Tachyon Dragon" & "Neo Galaxy-Eyes Cipher Dragon".
- In the same way that "Galaxy-Eyes Photon Dragon" is similar to "Blue-Eyes White Dragon", "Neo Galaxy-Eyes Photon Dragon" is similar to "Blue-Eyes Ultimate Dragon".
- It is an evolved form of "Galaxy-Eyes", just like the "Blue-Eyes Ultimate" is an evolved form of "Blue-Eyes".
- Its appearance is a non-evolved form with three heads (just like "Blue-Eyes Ultimate").
- Both cards have the same ATK, Type and Attribute.
- Its attack name is "Ultimate Photon Stream", whereas the attack name of "Blue-Eyes Ultimate" is "Ultimate Stream of Destruction".
- Both monsters require 3 monsters as Materials to Summon them.
- Although not necessary, it is possible to Xyz Summon "Neo Galaxy-Eyes" with 3 "Galaxy-Eyes" just as Fusion Summoning "Blue-Eyes Ultimate" requires 3 "Blue-Eyes".
- This card is Kite's second ace, being the evolution of his previous ace, just like Yuma's situation with "Number 39: Utopia" and "Number C39: Utopia Ray".
- This monster has three heads, visible on the tips of its wings. These "heads" look very similar to the heads of "Twin Photon Lizard".
- This card is the first non-"Number" Xyz Monster to be used by Kite Tenjo.
- The tail piece of this monster is more spear-shaped, unlike the one it had while it was a "Galaxy-Eyes Photon Dragon", which was more trident-like.
- In the anime, this card's Xyz Summon portal is unique to itself in that it resembles a black hole, instead of a red spiral or a galaxy (ironic, as its name contains "galaxy").
- According to Astral, this monster's original form has light dwelling within it similar to his own world. The light emitting from the body of "Neo Galaxy-Eyes" is similar to the light of the Barian World.
- This could be because it was made from the bond between Kite and Hart, and Hart possesses powers from the Barian World.
- The "sword" used to summon this monster resembles the Barian Emblem.
- This card's central head resembles the Barian Emblem as well.
- Mizar refers to this card as a "Number Killer", probably due to the fact that this card in the anime can negate the effects of "Numbers", including their Cannot be destroyed by battle except with a "Number" monster effect (this wasn't mentioned in the international dub).
- This monster appears in the artwork of "Galaxy Dragon Maelstrom".
- Aside from Pendulum Monsters, currently there is at least one three-headed Dragon-Type monster for five Monster Card categories: "Trident Dragion", "Atomic Scrap Dragon" and "Trishula, Dragon of the Ice Barrier" for Synchro Monsters, "Yamadron" for Normal Monsters, "Montage Dragon" for Effect Monsters, "Neo Galaxy-Eyes Photon Dragon", "Number C107: Neo Galaxy-Eyes Tachyon Dragon" and "Number 57: Tri-Head Dust Dragon" for Xyz Monsters, and "Blue-Eyes Ultimate Dragon" and "Dragon Master Knight" for Fusion Monsters.
