This chapter Oda showed off most of the important heart pirates. The mask guy operates the submarine, Shachi and Penguin can fight underwater and maybe use fishman like techniques, jean bart either has haki or tekkai and can block bullets with his body.
The one heart pirate that didn't get a spotlight this chapter was Bepo, who is confirmed to be the vice captain. Similarly, the one blackbeard pirate who seems to be absent this chapter was burgess.
I'm guessing in 1065, we will get maybe one or two panels of Bepo vs Burgess and Oda will maybe show off some of Bepo's powers. My personal theory: Law will use his awakening to create an artificial moon, like vegeta did in DBZ, allowing Bepo to go su long against Burgess.
