The White Dragon
Yu-Gi-Oh! (Toei) episode 3: "Clash! The Strongest Monster"
Blue-Eyes White Dragon is a character version of the card, "Blue-Eyes White Dragon".
Blue-Eyes White Dragon was the monster ka spirit of Kisara, although it only emerged while she was in an unconscious state.
With Kisara captured, Aknadin heard of the Dragon's power and hoped to transfer the ka to his son Seto, unconcerned that this would mean killing its current host. The imprisoned Kisara was unaware of her ka and thus unable to summon it. Seto, disgusted at the idea of using her without regard to her life, attempted to save her. He failed, and both their lives fell into danger. However, Kisara lost consciousness, causing the White Dragon to emerge and ultimately resulting in their rescue.
Seto had come to care deeply for Kisara during this time. He defended her until her death at the hands of Aknadin, who proceeded to possess his son. Perhaps showing that she felt the same about him, Kisara's spirit entered Seto's mind and destroyed Aknadin, freeing the young priest. Afterwards, Seto extracted the White Dragon ka and used it to fight Zorc Necrophades.
Interestingly, despite being always called 'Blue-Eyes White Dragon,' or even simply just the 'White Dragon' Blue-Eyes always has a light blue body as well as blue eyes. Later card designs also clearly showed the dragon to be blue rather than white.
In the first series anime, Seto Kaiba stole Sugoroku Mutou's "Blue-Eyes White Dragon" card. Soon after, Dark Yugi faced Kaiba in a Shadow Game of Duel Monsters to get the card back. Realizing he would otherwise lose, Kaiba slipped the card from his sleeve into his hand and summoned it. Since it was a Shadow Game, the spirit of Blue-Eyes White Dragon was summoned. However, its heart did not lie with Kaiba, so it destroyed itself, allowing Yugi to revive it with "Monster Reborn", ending the Duel in a Draw.
In Yu-Gi-Oh! The Falsebound Kingdom, the 3 Blue-Eyes White Dragons are named Azrael, Ibris, and Djibril.
