- This card has an updated version: Romanov Caesar, Dark Demonic Eye.
- This card is named after Gaius Julius Caesar, similar to Julius, Thunder Elemental and Gaius, Mystic Light Emperor.
- According to the background story, this creature is responsible for all events following the Sengoku Saga, due to him distorting the dimensions by using the Galaxy Shot - HELL in the final round of the sengoku tournaments.
- This card's DMX-19 Super Rare 100% Pack version has a Dramatic Card like artwork that says 悪夢 (Akumu, "Nightmare") as it's "dramatic" text. This indicates that it can be evolved over Funky Knightmares due to them being affected by cards that affect regular Knight creatures.
