Fans are already eagerly awaiting the arrival of "One Piece" chapter 804, and one of the biggest reasons behind the excitement is the war that is seemingly set to erupt.

According to Movie News Guide, it is widely believed that the Blackbeard Pirates and the Revolutionary Army are on a collision course that could cause untold damage to both sides, but what's unclear is exactly why the two sides may be fighting.

Fans are split on the motivation behind the looming war, with some suggesting weapons as possible causes and others insisting on more sinister possibilities. 

One reason for why the Blackbeard Pirates and, by extension, Marshall D. Teach are after the weapons is that they are rumored to have unknown powers, at least according to speculation online. This rumor is unconfirmed as of now, but the possibility of special weapons factoring into the equation could provide more intrigue to "One Piece" moving forward.

With a fight between the Blackbeard Pirates and the Revolutionary Army seemingly inevitable at this point, it is also believed that Marshall D. Teach and Monkey D. Dragon could also find themselves pitted against one another in an encounter that would surely provide tons of excitement to "One Piece" fans, according to Yibada.

There's no official word yet that the two are indeed set to engage in a lengthy battle, although all signs at this point are certainly pointing to what appears to be an inevitable encounter.

Interestingly enough, though all indications would suggest that a war between the Blackbeard Pirates and the Revolutionary Army is inevitable, some fans still believe that it is simply too early for the battle to take place now.

The war between the two sides would appear to be suited for a grander stage closer to the conclusion of the series, although putting off the battle now could leave chapter 804 of "One Piece" more hollow than necessary.
