Legendary Knight

The Legendary Knights are a trio of monsters introduced toward the finale of the Waking the Dragons arc, to finally defeat Dartz once and for all. They are the true forms of the cards "The Fang of Critias", "The Claw of Hermos", and "The Eye of Timaeus", and can be Summoned to the field through the use of "Legend of Heart".

Members

 * The three main cards in the set are "Legendary Knight Critias", "Legendary Knight Hermos", and "Legendary Knight Timaeus". All three have 2800 ATK and some ability that allows them to 'absorb' another card's effect, based on the effect of their corresponding Legendary Dragon.


 * Legendary Knight Critias: The true form of "The Fang of Critias", owned by Seto Kaiba. His effect allows him to 'absorb' a Trap Card and gain effects based on it, similar to how "The Fang of Critias" can fuse with Trap Cards. In the anime, he was shown to absorb "Mirror Force" and "Attack Guidance Barrier". His blade's name is "Sword of Wisdom".
 * Legendary Knight Hermos: The true form of "The Claw of Hermos", owned by Joey Wheeler. His effect allows him to redirect attacks to himself, and also remove from play monsters to either gain those monsters' effects or multiply its own ATK and reflect attacks. In the anime, he was shown to absorb "Obnoxious Celtic Guardian", "Alpha The Magnet Warrior", "Beta The Magnet Warrior", and "Gamma The Magnet Warrior". His blade's name is "Sword of Renewal".


 * Legendary Knight Timaeus: The true form of "The Eye of Timaeus", owned by Yugi Muto. His effect allows him to absorb other monsters. In the anime, he was shown to absorb "Legendary Knight Critias", "Legendary Knight Hermos", "Kuriboh" (as well as "Multiply"), and "Big Shield Gardna". His blade's name is "Sword of Justice". When combined with "Big Shield Gardna", the combination was named "Full Barrier Shield". When combined with the other two Knights, the combination was named "Knight of Destiny" (see below).


 * Timaeus the Knight of Destiny: The result of "Timaeus" absorbing both "Critias" and "Hermos" to form a new Fusion Monster, this card had the ability to gain ATK equal to the ATK of the absorbed monsters. In addition, it could not be destroyed by battle; these two effects were ultimately combined to destroy Dartz' "Divine Serpent Geh" and cause him to lose the Duel.

Voices and Mannerisms
The three Legendary Knights sound and act like their owners. "Hermos" sounds like Joey, "Critias" sounds like Kaiba, and "Timaeus" sounds like Yugi.

Trivia

 * "Divine Dragon Knight Felgrand" may have been partially based on the Legendary Knights, having a matching 2800 ATK as well as a connection with a Dragon.
