Hehe xD dont worry, OP is not so much about surprises and its draw is not whats going to happen next, its the actual journey. Its the experience. Knowing the characters name is not a big deal. Going through adventures with the Strawhats is the important part. Most shonen have the main character try to achieve 1 goal(Naruto:become hokage, here, get one piece). Or so it seems. Later kn you realize the main character just wants to be free and go places and experience new stuff. Freedom, the most freedom, is Luffys main goal.
U talkin about One Piece or real life??? In One Piece, Blackbeard is a pirate looking for One Piece. The treasure left by Gold Roger. The treasure that will make the finder the Pirate King. Blackbeard is awesome cuz he is exactly like Luffy. In EVERY way but one. Instead of freedom he wants power. I call him Dark Luffy. He grows as the series goes on. From a nobody to the strongest pirate in the world(not confirmed, still in early second half, but its obvious to everyone and their mums this guy is the final villain)
