Both are Match winners with a similar name pattern (King and Queen; Goldfang and Silvercrown).
This card and "Queen Nereia the Silvercrown" were the first Match winners to not need a specific Type of monster to be initially Summoned; however, they do require a specific Type of Xyz Material to win the Match by their effects.
This would later be standard for all Xyz Monster Match winners.
The word "Gold" in this card's name may be a reference to the fact that it was awarded to the winner of the Yu-Gi-Oh! World Championship 2011, in contrast to "Queen Nereia the Silvercrown, which was awarded to the tournament's 2nd, 3rd, and 4th place finishers.
