I feel bad for you.....
Read OP for 20 years, and still cant tell that the third party ally doesnt defeat the main baddies. Of course Oda re-affirming it 3 times this arc wasnt enough for you either. Oh well....
Sorry but you need to read the post-time skip chapters again because you are being misinformed and delusional. I'm don't speak like you to push my agenda or just for the sake of debate. When I speak about something I know that it's going to happen because I back it up with clear proofs. You were all making fun of us when we said that Zoro will fight Kaido. You were saying no and that only Luffy will fight Kaido and that Zoro will fight King or Queen and bla bla bla. But you forgot an important thing. THE STORY IS CHANGING. This isn't East Blue saga or Enies Lobby. This is an all-out war. The straw hats can't handle all the enemies in an all-out war. Who fought Machvise, Lao G, Gladius, Dellinger, Trebol, and Diamante in Dressrosa? Did the straw hats fight them? NO. Did Luffy fight Doffy alone? NO. In an all-out war, Oda needs to introduce other important characters to the story and give them important fights
That's why King vs Marco will happen.
X-drake will fight Apoo or another character.
Yamato will fight Jack.
Carrot fought Perospero.
We also have Law, Killer, and Kid fighting Kaido and Big Mom.
The highlights will be on the straw hats, they will fight the main opponents but other important characters will back them up.
I can't with you guys...smh
