for the record, what Robin did as a villain goes above and beyond everything Monet did.

I heard that the next ally was a former enemy. It's likely that both this and the above are just rumours.

It's looking like Jinbe might be the first of Luffy's "Division comanders" when Big Mam falls, since he has the Sunny pirates survivors as well. that being the case, then he wouldn't count as the last crew member. Since Luffy hasn't recruited in ages, it's also possible he never will again too, but you never know.
