- This card's name is a reference to Valkyrie.
- Magna in this card's name is not merely a tongue-in-cheek rephrasing of "magnet"; it is a Latin word meaning "great." This is fitting, given this monster's stats.
- This monster is the first Level 8 Rock monster in the TCG/OCG, as well as the first Main Deck Rock monster that cannot be Normal Summoned.
- This card's ATK/DEF are both 3/4 of the sum of the respective ATK and DEF of the 3 "Magnet Warrior"s used to summon it, rounded up.
- In Yu-Gi-Oh! The Falsebound Kingdom, this monster is a fusion of the required monsters usually sent to the Graveyard to Summon this monster.
- This card's artworks are taken from Yu-Gi-Oh! Duelist Duel 129: "Combine Your Power!", specifically from the panel where this monster is shown being Summoned, albeit with minor differences in detailing.
- True to its Summoning condition, this monster has the body and sword of "Alpha The Magnet Warrior"; the wings, feet, and a majority of its helmet of "Gamma The Magnet Warrior"; and the gold part of its helmet has attached to it the magnet horns of "Beta The Magnet Warrior" and the horn on top of the head of "Alpha The Magnet Warrior".
- This monster's formation from the above three components is depicted in the artwork of "Magnetic Field".
- This card's Summoning conditions are incorrect in the Spanish lore, as a "misprint" in Retro Pack 2 states that you only need to Tribute "Alpha the Magnet Warrior" to Special Summon this card. Interestingly, in the Legendary Collection 3: Yugi's World Mega Pack, the name of "Alpha the Magnet Warrior" in the card's lore was spelt with the Spanish spelling of the word "alpha" ("Alfa"), instead of "Alpha" which had been used for the name of said card.
