Card Trivia:Chronomaly Crystal Chrononaut
- This monster appears in the artwork of "Chronomaly Pyramid Eye Tablet" and "Orichalcum Mirage".

- "Chrononaut" is a portmanteau of the Greek word for "time" (χρόνος chronos) and "sailor" (ναύτης nautes), which combined, would mean "time traveler". This reflects the general theme of the "Chronomaly" archetype, where its members are based on artifacts found in a very unusual or apparently impossible archaeological context which would challenge conventional historiography and chronology if authentic.
- This monster features a mirror in its chest, referencing how it can "reflect" any battle damage it would take from an opponent's attacking monster back at the opponent.
