While there's no single episode dedicated solely to the Celestial Dragons, their impact and role are significant throughout the arc, particularly in:
* Episodes 475-489: This is where the conflict involving the Celestial Dragon, Saint Charlos, and his attempt to purchase Fisher Tiger, a powerful Fish-Man, as a slave unfolds. This incident sparks a chain of events leading to the Marineford War.
* Episodes 489-516: During the Marineford War, the Celestial Dragons are shown watching the battle unfold, and their presence adds to the tension and complexity of the conflict.
The Celestial Dragons' role in the Marineford arc is crucial to understanding their power, influence, and the nature of the world government's hierarchy in One Piece.
