Legendary Dragon " Legendary Dragon " ( の " Densetsu no Ryū " ) is an archetype of the dragon forms of the three " Legendary Knight s " . The archetype was introduced in " Dragons of Legend " and was featured in the Waking the Dragons arc of the " Yu - Gi - Oh ! " anime . Despite all of the members of this archetype lacking " Legendary Dragon " in their names , they each include a name condition that causes them to always be treated as " Legendary Dragon " cards . The names of the " Legendary Dragons " come from the ancient philosopher ' s workings . The specific body part in the name corresponds to where they were stabbed and sealed during the war in the " Yu - Gi - Oh ! " anime . " Legendary Dragon of White " is not a " Legendary Dragon " card because it does not have 「 の 」 in its Japanese name . Fusion Monsters . Each of the Legendary Dragons can Special Summon one of a number of Fusion Monster s by using another card . In the " TCG " and " OCG " , only " The Eye of Timaeus " uses the other card as a Fusion Material ; " The Fang of Critias " and " The Claw of Hermos " instead send the card to the Graveyard . Anime . These cards first appeared in the Waking the Dragons arc of the " Yu - Gi - Oh ! " anime . Yugi Muto , Joey Wheeler and Seto Kaiba each receive 1 of the 3 Legendary Dragon cards : " The Eye of Timaeus " , " The Claw of Hermos " and " The Fang of Critias " , respectively . According to Kaiba , the Dragon he received , " Critias " , seemed just as powerful as the Egyptian God Card s . These cards are the dragon forms of the three " Legendary Knight s " who used to live in the Dominion of the Beasts and answered Ironheart ' s call to defend Atlantis . Dartz transformed them into dragons to weaken them . The great ancient war ended in a draw , with the Dragons sealed away in their realm and the Leviathan severely weakened and diminished to a shadow . Although their names are known prior to their release in the dub anime , in the original anime , no one — not even the monsters — knows the names of these dragons except for their chosen Duelists , who learn their name upon releasing them , without even being told what their names are . Thus , they are referred to as the Nameless Dragons in the Japanese anime sometimes even by their chosen Duelists . Properties . In the anime , they do not belong to any regular card type ; their cards are colored blueish , but not the same as Ritual Monster s . They can be played whilst " Spell Canceller " is on the field , so are not Spell Card s unlike in the " TCG " / " OCG " . They are usually played in Monster Card Zone s , but Yami Yugi placed " The Eye of Timaeus " in a Spell & Trap Card Zone during his Duel with Weevil Underwood . " The Eye of Timaeus " can fuse with other monster s to become new Fusion Monsters . Yami Yugi fused this card with " Dark Magician " and " Dark Magician Girl " to form the respective Fusion Monsters : " Amulet Dragon " and " Dark Magician Girl the Dragon Knight " . He once attempted to fuse it with " Poison Butterfly " but it did not work as at this point Yami Yugi had lost Timaeus ' trust , because he played " The Seal of Orichalcos " . The " Claw of Hermos " can fuse with other monsters to form new Equip Spells . Joey fused this card with " Time Wizard " , " Red - Eyes Black Dragon " , " Rocket Warrior " and " Big Bang Blow " to make the respective Equip Spells : " Time Magic Hammer " , " Red - Eyes Black Dragon Sword " , " Rocket Hermos Cannon " and " Big Bang Dragon Blow " . In addition , Yami Yugi also fused " Queen ' s Knight " with this card to form " Goddess Bow " . The " Fang of Critias " can fuse with Traps to form new Fusion Monsters with effects similar to the Trap Card . Seto Kaiba fused this card with " Crush Card " , " Tyrant Wing " and " Mirror Force " to form the respective Fusion Monsters : " Doom Virus Dragon " , " Tyrant Burst Dragon " and " Mirror Force Dragon " . " Legend of Heart " allows them to transform into their Legendary Knight forms : " Legendary Knight Timaeus " , " Legendary Knight Hermos " and " Legendary Knight Critias " . These three Legendary Knights , under the right conditions , can also be combined to form " Timaeus the Knight of Destiny " . Official Legendary Dragons Decks . There have been three official decks created by Konami .
