Card Trivia:SPYRAL GEAR - Last Resort
- "SPYRAL Super Agent" and "SPYRAL Sleeper" appear in this card's artwork.
- This equipment appears in the artwork of "SPYRAL MISSION - Rescue".
- This card is based on the Metal Gear series of weapons from the eponymous series of games.
- Its effect to allow the equipped monster to attack directly may be a reference to the weapons' ability to launch a nuclear attack from anywhere on the planet; most famously said to be the undetectable Metal Gear REX, which was also the only playable Metal Gear in the series, used by Old Snake.
- This card also draws on some design elements of the Dexo-Transformer from Dexter's Laboratory.
