Charlotte Linlin, also known as Big Mom (ビッグ・マム), is the captain of the Big Mom Pirates. She was the last Yonko to be named, and is the only female one of the four. Her epithet was first revealed just after the Battle of Marineford and the death of the Yonko Whitebeard, and her real name was first mentioned by Pappug in the Fishman Island Arc.
