- "Gradius", "Victory Viper XX03", "Jade Knight", "Falchionβ", and "Lord British Space Fighter" are all playable ships in Konami's Gradius Gaiden video game, hence their similar appearances. The effects of these cards are meant to replicate the special powers and weapons used by the five ships.
- Option Units are featured in many mecha anime and video game series. They are self-propelled weapon units deployed by another vessel. In the case of the Gradius video games, the playable ships can summon Options with power capsules. The Options fire all the same weapons as the ship that deploys them, essentially turning one ship's worth of weapons into a devastating force. The Options themselves are indestructible; however, when the main ship is destroyed, so are its Options.
- This monster seems to be destroying a "DUCKER Mobile Cannon", a common enemy in the Gradius games.
