- "Galaxy-Eyes Photon Dragon" resides in "Astral World" (according to Astral, it has light dwelling within it similar to his own world, likely because of its true form harnessing power from Astral World), while this card exists in the rival dimension, Barian World.

- This monster's roar in the anime is similar to how "Galaxy-Eyes Photon Dragon" roars in the Japanese version.
