Card Trivia:Dark Highlander
- This monster appears in the artwork of "King's Consonance".
- This card's name is likely a reference to the 1986 film Highlander. This card's effect to prevent any player from Synchro Summoning may be based on the film's iconic tagline "There can be only one", since this usually means it is the only Synchro Monster on the field.
- This card seems to be an antithesis to "Seven Swords Warrior".
- This card belongs to Jack Atlas, while his rival Yusei owns "Seven Swords Warrior".
- Both cards are Level 7 Synchro Monsters.
- Both cards use Equip Cards to inflict damage to their opponents; this card destroys Equip Cards, while "Seven Swords Warrior" supports them.
