Lux

Lux is the doctor for Dolly's crew, he grew up alongside her and learned medicine under the previous captain's doctor. He is very patient, though he doesn't let others get away with things he doesn't tolerate. He has a strong protective streak over Dolly. He has a complicated relationship with Bromelia, which culminates when he finds Bromelia near death and nurses him back to health. He persuaded Dolly to allow Bromelia to join the crew, despite her strained relationship with him, under the excuse of studying his devil fruit.
