A Link Monster (Japanese: リンクモンスター Rinku Monsutā) is a type of Monster Card. The color of their card frame is dark blue, which is similar to that of a Ritual Monster, but with a hexagonal pattern similar to a honeycomb structure. These cards are placed in the Extra Deck. If a Link Monster is not Link Summoned first, it cannot be Special Summoned from the Graveyard or while banished (unless it specifies another way to properly Special Summon it).
