Episode Title:
Celestial Spirit Beast.
Episode Description:
Although Natsu and the others defeat Ophiuchus and destroy the celestial globe, they are unable to prevent the Eclipse spirits from being absorbed by the Celestial Spirit King. Horologium appears and provides the wizards celestial clothing, allowing them to enter the celestial spirit world and confront the king, who appears as a giant, amorphous monster called the Celestial Spirit Beast. The beast uses its powers to transform the wizards into constellations, leaving only Natsu, Lucy, Happy, Gray, Erza, and Gajeel standing. Natsu senses that the Eclipse spirits are still alive inside the beast and enters its mouth with Happy to save them while the rest of his friends continue to fight the beast outside.
