Card Trivia:D/D Savant Kepler
- This monster is based on Johannes Kepler.
- This is further expressed in the design of the card, which features several orbs racing along on tracks. Kepler postulated the current model of the Solar System that we know today, which was later proven by Galileo Galilei.
- This card is a polar opposite to "D/D Savant Galilei" in terms of its Level, Pendulum Scale and Pendulum Effect.
- In the anime, the Pendulum Scale-decreasing effect of this card is explained by this card being an unstable Pendulum Monster prototype.
