"Big Mom Defeated!! A New Emperor?!
Luffy-chan, wildest of the Supernovas, is at it again! The man responsible for the only prison break from Impel Down in its history and the defeat of Doflamingo has now bravely entered Big Mom's territory to settle an old score.
Under his command now are the Sun Pirates, Castle Pirates and Germa 66, that most evil of kingdoms. This brings Luffy's fleet up over 10 major pirste crews and a combined bounty of 50 billion!
Luffy defeated 2.5 billion worth of Big Mom's forces personally, and traded blows with the Yonko before stealing two of her crew members and jauntily left Big Mom's destroyed territory.
Whatever will the Fifth Yonko do next? There is no guessing at this point!"
