to be honest though it will not matter to me if Luffy gets help from others but for some reason i think he might solo Kaido , Luffy is known for doing the impossible and what people say about Kaido in one vs one , bet on Kaido , and Oda was wondering how he is going to make Luffy take Kaido make you think he is thinking about making fight him alone.
Luffy usually tells the others that is my opponent , the exception was only Doffy since he allowed Law to fight him because of Law personal motives .
and he told Kid off as he said that he will be the one who will take Kaido down.
