RookChessmon is a Puppet Digimon whose name and design are derived from the black "Rook" chess piece. It has an appearance like a fortress which boasts impregnable defense. Although it's a gigantic Digimon it is very fast, and it defends against the opponent's strikes, then attacks. Its catchphrase is, "The opponent is nothing after me!"
