- This is the first "Number C" Summoned by "Rank-Up-Magic Barian's Force".
- This is the first monster Summoned by "Rank-Up-Magic Barian's Force" that does not belong to the "CXyz" archetype.
- Ironically, out of all "Number Cs", this one has gone the longest without having its effects revealed. It was first summoned in Episode 83 and its effect was not used until Episode 132.
- This monster's initial appearance in the anime bears a resemblance to the phoenix mode of "The Winged Dragon of Ra".
- Just as "Number 107: Galaxy-Eyes Tachyon Dragon" is very similar to "Galaxy-Eyes Photon Dragon", this card shares many similarities with "Neo Galaxy-Eyes Photon Dragon".
- Just as "Neo Galaxy-Eyes Photon Dragon" could be a reference to "Blue-Eyes Ultimate Dragon", this card could be a reference to "Cyber End Dragon".
- Both "Cyber End Dragon" and this card are machine-likes, but this card is Dragon-Type monster instead of Machine-Type.
- Both are triple-headed dragons.
- This dragon like its base form, could negate card effects, but unlike its base form it did this by completely rewinding time back to the start of the turn, and undoing and preventing everything that happened in that turn from happening again.
- Like "Number C39: Utopia Ray" and "Number C32: Shark Drake Veiss", "Neo Galaxy-Eyes Tachyon Dragon's" colors are reversed compared to his base form.
- "Tachyon Dragon" is dark-purple, "Neo Tachyon Dragon" is light-yellow.
- This card appears in the artwork of "Neutrino Dowsing".
- This monster has the highest ATK of "Number C" so far.
- On that note, it has the highest ATK jump from its original form, as the difference is 1500 ATK from "Number 107: Galaxy-Eyes Tachyon Dragon".
- So far, this is the only "Galaxy-Eyes" monster that doesn't gain any ATK by its effects.
- Unlike its base form who can go in past and decide its own future, this card returns everything to the beginning of the time (in a turn).
