- This monster is based on "Crystal skulls" which were carved from quartz and were believed to be of pre-Columbian origin.
- This monster could also, to a lesser extent, reference the film Indiana Jones and the Kingdom of the Crystal Skull.
- This monster doesn't have a body. Its anime effect can Special Summon "Chronomaly Crystal Bones" because that monster is this one's body.
- "Chronomaly Crystal Chrononaut" may also be an enhanced, combined form of the two monsters, due to its similar name and appearance to the two.
