A Digimon like a fortress boasting an impregnable defense. This massive Digimon is somehow quite fast, able to defend against enemy attacks and launch its own offensives. RookChessmon’s catchphrase is “The opponent is nothing after me!” It uses its special move Stronghold to charge and mow down the enemy even as it stands at attention, and it fires Rook Gatling from the barrels on its arms. Finally, Castle Wall is a firm and unshakable defense technique.
