Card Trivia:Gilti-Gearfried the Magical Steel Knight
- This is one of the cover cards of Premium Pack 2020.
- Visually, this monster is a Fusion of "Gearfried the Iron Knight" and "Giltia the D. Knight".
- In the Yu-Gi-Oh! R manga, this monster is Fusion Summoned by fusing "Gearfried the Iron Knight" and "Giltia the D. Knight".
- In the OCG/TCG, this card's Fusion Materials are two generic Warrior monsters with different Attributes, making "Gearfried the Iron Knight" and "Giltia the D. Knight" valid candidates for its Fusion Summon.
- This card's effects in the OCG/TCG are based on the effects of Spell Cards and Trap Cards used on this card by Jonouchi during his duel against Reiko Kitamori in the Yu-Gi-Oh! R manga, where it is a non-Effect Monster.
- This card's effect to gain ATK equal to half its current DEF during damage calculation when battling an opponent's monster is taken from the effect of "Extra Boost", which adds half the DEF of a target monster to its ATK.
- This card's effect to make a second attack during each Battle Phase if Fusion Summoned using monsters on the field is derived from the effect of "Relentless Attacks", which allowed this monster to make a second attack immediately after its first one.
- This card's OCG/TCG artwork is taken from Yu-Gi-Oh! R Duel Round 20: "The Rage of Kaiba!!", specifically from the panel showing this monster being Summoned.
