Card Trivia:D/D/D Dragonbane King Beowulf
- This is one of the cover cards of Pendulum Domination Structure Deck.
- This monster is based on Beowulf.
- This monster's wolf-like appearance is a reference to different possible meanings of the name "Beowulf": "Bee-Wolf" ("hunter of bees"), "Beado-Wulf" ("war wolf"), or "Beow-Wolf" ("wolf of Beow").
- This card has the same ATK/DEF (3000/2500) as the signature cards of main rivals in the anime: Seto Kaiba's "Blue-Eyes White Dragon", Chazz Princeton's "Armed Dragon LV10", Jack Atlas' "Red Dragon Archfiend", and Kite Tenjo's "Galaxy-Eyes Photon Dragon".
- This card's name, "Dragonbane", is also a reference to how the aforementioned cards are Dragon monsters.
- Ironically, this monster is based on Beowulf, who killed a dragon, as told in his epic poem.
- This card is also a reference to how "D/D/D Doom King Armageddon" is the first signature card of a main rival in the anime to not be Dragon.
