Card Trivia:D/D Savant Thomas
- This monster is based on Thomas Edison.
- The top half of this monster shaped like a incandescent light bulb, arguably Edison's most famous invention.
- This monster has a heraldic sun for a face, possibly referencing the following quote by Edison in conversation with Henry Ford and Harvey Firestone: "We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy — sun, wind and tide. … I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that.".
- The bottom half of the monster bears a resemblance to the horn of a phonograph, another of Edison's inventions, which is connected to a red phonograph cylinder record.
- The fact that this card was first used in the anime as a Pendulum Scale alongside "D/D Savant Nikola", based on Nikola Tesla, may be a reference to the war of the currents, a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s including commercial competition, a debate over electrical safety, and a media/propaganda campaign that grew out of it. In particular, Edison advocated for the use of direct current, which was at odds with Tesla, who supported the usage of alternating current.
- Edison and Tesla's enmity, partly resulting from the war of the currents, is reflected in the Levels and Pendulum Scales of this card and "D/D Savant Nikola", where one card's Level is equal to the other card's Pendulum Scale, making the one card unable to Pendulum Summon the other if it is used as a Pendulum Scale.
- Unlike previous "D/D Savant" cards, this card derives its name from the first name of its namesake, rather than the last name. Also, unlike previous "D/D Savant" cards, the Spanish print of this card uses a different wording in its translation ("D/D Thomas the Savant" instead of "D/D Savant Thomas").
