Fire fox Kin'emon

I think Kin'emon is going to be with the straw hats for a while or at least at the end of Kaido's arc.He has shown his interest in fighting against Kaido specially since Oda hinted about his reasons but never said why. This is when they just left Punk hazard and are on the ship.
Also he will be a gateway for the straw hats to go to Wano as well.

Well, the sure thing is that he is going to play a major role in the arc, considering that the picture of the Pirate Alliance Saga has the StrawHats, the Heart Pirates and Kinemon with his son.

Much like what Max-aniki said. Besides, he's an interestin character, he has his own issues and weird habits, and his personality seems to blend with the whole Strawhats theme pretty nicely.

Well, considering that nothing is known about his fruit, I am pretty sure that Kinemon has too many things to offer before he gets kicked out of the main story of One Piece. I mean, we need to find out his goals and stuff and most importantly, his fruit ability and his fruit's name.

i am more interested in his past than his fruit.but the fact that he can create a samurai helmet,could mean that he can create the best armor there is!

Well, as we have already seen, he can create many different kinds of clothes. I could see him joining the crew, just because Oda likes drawing his characters with different clothes.
