Card Trivia:Shadowknight Archfiend
- This monster appears in the artwork of "Pandemonium".
- This card is one of the six chess-themed "Archfiend" cards that debuted in Threat of the Dark Demon World in the OCG and Dark Crisis in the TCG, each one featuring chessboard background, all of whom are based on a chess piece.

- This monster's shield and sword is similar to that of "Vilepawn Archfiend", albeit with different color.
