"Fairy Tail" chapter 504 is arriving in bookstore shelves in less than a week, and it is already expected that the upcoming chapter will pack more action as Gray and Natsu/Ethereal Natsu Dragneel (E.N.D.) will finally engage in their prophesied face-off.

To those who haven't purchased a copy of "Fairy Tail" chapter 503, be warned that this article contains spoilers. Those who have already availed themselves a copy, though, this article contains some recaps.

In the current chapter, Dimaria is about to punish Lucy for being responsible for influencing Brandish's loyalty. However, just before Dimaria could unleash her wrath, Lucy loses her consciousness.

The next scenes show Lucy gaining consciousness and unrestrained from the now-broken chair where she has been tied to. On the other hand, Natsu, who was previously tied to another chair, is nowhere to be found, while Dimaria is seen bleeding.

However, as it is uncertain how things end up how they are for the three mentioned characters, it is expected that things will be fully revealed in the upcoming chapter 504 of "Fairy Tail."

As Natsu is nowhere to be found, and Dimaria is reeling from the still unknown events, it is alleged that the upcoming chapter of "Fairy Tail" will finally confirm that Natsu has, indeed, already transformed into E.N.D., much more that Dimaria is murmuring about a monster that could not be controlled even by her time-freezing power.

Now that Natsu is suspected to have turned to E.N.D., it is speculated that the highly anticipated clash between him and Gray will finally unfold in the upcoming chapter 504 of "Fairy Tail" as they already meet in the current chapter.

Despite his transformation, though, Natsu can still recognize Gray and knows that they are friends. With this, some fans believe that the two may not really end up killing each other and will reconcile instead.

Will the much-awaited showdown of force between E.N.D. and Gray finally happen in "Fairy Tail" chapter 504? If yes, who will emerge as the victor?

Answers to these questions and more will be revealed when "Fairy Tail" chapter 504 hits the stores in the coming days.
