Natsu Dragneel vs. Taurus (Eclipse)

Natsu Dragneel vs. Taurus (Eclipse) is an anime-exclusive fight fought between Fairy Tail Mage Natsu Dragneel and the Eclipse Celestial Spirit Taurus.

Prologue
After acknowledging the goal of the Eclipsed Celestial Spirits: Liberum, Erza starts forming teams for gathering information of the said ritual with Natsu Dragneel, Lucy, Levy, Yukino and Happy on a mission to the Magic Library. Suddenly, Lucy notices the absence of Natsu and her Celestial Spirits as the latters have travelled to the Celestial Spirit World, in an attempt from Natsu to go against Loke and the other spirits to bring them back.

Battle
As Natsu start calling for the Eclipsed Spirits, six pillars are thrown at him in tremendous force by the Eclipsed form of Taurus, welcoming the former to the Celestial World. As the Fire Dragon Slayer tries to reason with latter, the Golden Bull charges at him, kicking him away. The fight proceed, with Taurus having the upper hand over Natsu. As the latter charges at his opponent, Taurus blocks the incoming attack with ease forcing him back and dodging his Fire Dragon's Roar. As Taurus keeps blocking Natsu's Firing attacks, the latters tries to make the Celestial Spirit recall his memories with his past owner but in vain. As Taurus states that he forgot the contract that was between him and a human, thus enraging the Dragon Slayer. Natsu then charges impulsively at him in his Fire Dragon's Sword Horn in which Taurus easily jumps over and watches as Natsu falls in the bottomless world.

Aftermath
After the fight, Natsu leaves the Celestial World by unknown means and land in the Magic Library during the quarrel between Lucy, Yukino and Levy against Virgo, with the latter escaping with the Celestial Globe. Levy then informs the Mages that the price of the freedom that Liberum takes is the lives of the Spirits, as they will be able to live for twelve days only before dying, leaving the group in strong shock.
