Card Trivia:Ancient Gear Reactor Dragon
- This monster's chest device is based on a nuclear reactor.
- Fittingly, the kanji 「古代の機械熱核竜」 in this card's Japanese name translates to "Ancient Machine Thermonuclear Dragon".
- This monster is an upgraded form of "Ancient Gear Gadjiltron Dragon".
- Both monsters have a similar positioning of their multiple wings and the pair of massive spiked gears in their pelvic regions, bladed attachments on the various tips on their wing membranes, segmented necks and tails (with wiring in the segmented gaps and dorsal tips on the segments), and chest regions with a ribcage beneath them (with this monster missing a chunk in lieu of the energy source placed there).
- Both cards are EARTH Machine monsters with 3000 ATK and/or DEF; this card is also 1 Level higher (9) than "Gadjiltron Dragon" (8).
- Both cards also gain effects if they are Tribute Summoned by Tributing "Gadget" monsters.
