How Black Beard can use multiple fruits…...
If this has been posted sorry I didn't want to scan through 272 pages.
In Chapter 225, after being beaten by Bellamy and Associates, and a second run in with Blackbeard eating his pies.....after walking away Luffy and Zoro agree and say "it wasn't he....it was "those" guys"At this moment Blackbeard is both ..... Teach AND Thatch. A possible absorption of of Thatch's Fruit or maybe even his soul, something along those lines, full capabilities of Yami Yami have no been seen. Later on after Marineford they are Teach, Thatch AND Edward Newgate (White Beard)The Real Blackbeard's name was Edward Teach, or (Edward Thatch), Which is a combination of the two.
could be referring to his hidden crewmates, but i just happened to put a little more thought into it and happened to share it
