@BeariousJones:

Wicca…why do you say that? What type of potential?

The potential to be Zoro's compass. :p

I have some thoughts about Kaidou and the group from Wano.

Well first off I believe Kaidou originates from Wano and tried to introduce new things to Wano like robotics or Devil Fruits(specifically Zoan), but the shogun did not agree believing Wano did not need any outside interference into their way of life. So Kaidou was ejected from the country and proceeded to become a part of Hanokuni. They were much more open to him and his ideas. Later on Kaidou decides to get revenge on Wano with the help of Hanokuni. Only 4 people escaped from the invasion and they were the Shogun, his right hand man Kanjuro, the Shogun's son, and Kinemon Momonosuke's man nanny. The shogun never caring for his son though has little emotional attachment to him. Kinemon has raised Momo for his entire life and Momo knows him as his true father and Kinemon not having any children of his own treats Momo as a son. They were heading for Zo, one of Kaidou's main island Zo being a zoo, to defeat Kaidou and hopefully regain control of the country. On the way there though they ended up on Dressrosa, this would explain why Doflamingo has captured Kanjuro and is trying to capture Kinemon too.

Does anyone think it is possible Blackbeard gained more significant crew members over the timeskip?

I also think it would be cool if some people weren't locked down to one opponent during the final fight, like they switch between each other.

Momonosuke is not really the son of Kinemon but the child of Robin and Dragon who was born 8 years ago after their one night stand which is also why Dragon had revolutionaries save Robin from Tequila Wolf. His name should really be Monkey D. Suke but was changed to Momonosuke (Monkey becoming Momono) when Kinemon picked him up from an adoption center. This explains why Robin didn't care that she bathed with Momo or that his head was all up in her boobs.

I think Ricky is the son of Kyros. ​maybe even the sister of rebecca

I still want Momo to eat it then he can be a real dragon.

Rebecca is totally a subordinate of Blackbeard and will get the fruit from Lucy and take it to him with Jesus and Cavendish after learning that his new friend Lucy is really Luffy he also joins Blackbeard along with Bellamy who got rejected by DD. Bartolomeo teams up with Law and Lucy to take out DD/Kaidou. And Ricky will win Block B and be Lucy's final opponent in the tournament before Diamante and reveal himself to be Sabo/Gin. Yeah crack fantasies!

I see Jesus Burgess recruiting someone for Blackbeard's crew in this arc, such as Bartolomeo, Cavendish, or maybe Rebecca(who is totally secretly evil)

Young Bonney is in the Strawhat's ship with Young Vergo and Monet

If Rebecca were to join(not saying she would) I would hope she doesn't use the Mera Mera fruit but a bronze bronze fruit(so that luffy can get his statue) and uses something besides the sword or uses the shield as her main weapon for crew variety.and so that she doesn't overlap with Kinemon :D
