While many believe that Blackbeard’s third Devil Fruit will be a mythical Zoan, I have another theory: what if it’s actually Sakazuki’s Magma fruit? Here’s my reasoning:

The World Government and Blackbeard represent Japan’s historical enemies. The WG symbolizes a superpower with nuclear capabilities, while Blackbeard embodies nature itself. Japan frequently experiences natural disasters like earthquakes and volcanic eruptions, which often bring tragedy, loss, and darkness.

I believe Blackbeard will kill Sakazuki and acquire his fruit, even though it might not be particularly useful for him in the long run. This theory aligns with the broader themes of nature versus power in the series.
