Yeah, you can like any female One Piece character, but it's pretty clear Oda doesn't put much effort into them. He often uses overdone tropes, like Baby 5, the maid who'd kill herself if someone told her to.
Yamato's whole Oden fangirl thing was awful and irritating.
And let's not forget how he draws them – three circles and an X!
It as simple to make them develop as characters via by baby 5 can think for herself if she wants to do something or not in the end. Then Yamato saying okay, I dont need to be Oden to be free. Simple character development and Oda can't manage to do that.
