Captain Jack's real identity, Trafalgar Law and Dyk Nekomamushi's secret scheme, and mass destruction weapons are the key revelations in "One Piece" Chapter 810.

According to The Bitbag, the real identity of Beast Pirates Captain Jack the Drought is Axe-Hand Morgan. He is a former Marine official who is known to hold an axe for his right arm. Morgan is also one of the first Marines whom Luffy had fought and had taken down in a battle.

Some fans hold on to the belief that Morgan was Captain Jack, since he was speculated to have consumed the zoan-type fruit mammoth that was once under his possession. Then, rumors said that he took the identity of Jack the Drought, a follower of one of the most influential pirates in "One Piece."

On the other hand, some fans disagree that Captain Jack is Morgan, as the latter was viewed as too fragile and minor as a "One Piece" character who would later become the right hand man of one of the best pirates in the series.

With Law and Nekomamushi's plans, it is rumored that the duo are set to track down Raizo's location in "One Piece" Chapter 810. In the previous chapter, Nekomamushi had a battle with Captain Jack, which left the latter with no choice but to transform into his human form.

"One Piece" Chapter 81 is also set to feature the last ancient weapon, according to Movie News Guide. According to the report, the Mink Men and the elephant Zou Island have the key that is needed to access the last ancient weapon. According to rumors, this could be linked to the three weapons that could lead to a massive destruction. These weapons are Poseidon, Pluton, and Uranus.

While it is believed that the key weapons could only be acquired from the Mink men on the elephant Zou Island, there are things yet to be revealed about the said group of people who inhabit the historical place.
