One Piece is at a crucial juncture in its story right now, with Luffy and his allies facing down two of the Yonko (or Four Emperors), the most powerful pirates in the world. Chapter 1040 saw the momentous defeat of one of these emperors, Charlotte Linlin, better known by her epithet «Big Mom».
Big Mom's defeat by Luffy's allies (for the time being) Trafalgar Law and Eustass Kid, has major implications for the future of One Piece. Currently, it's unknown if she is alive or dead, and the answer will affect future events significantly.
One Piece: Rokushiki, Explained
Big Mom is the only female Yonko, and is consequently one of the four most dangerous pirates in the world. Her bounty of 4,388,000,000 berry is the fourth-highest ever confirmed, and if alive the second-highest for a living pirate after her ally Kaido (who trails only the deceased Whitebeard and Gol D. Roger). This massive bounty is due to a few factors. On top of being a pirate, Big Mom is the queen of Totto Land, an archipelago in the New World, and has attempted to maintain control over further territories like Fish-Man Island, making her a threat to the World Government. Her nation and subsequently her crew is made up primarily of her 85 children.
Aside from her family, Big Mom's military force stems from a few non-related allies and, importantly, the Homies, servants she creates from inanimate objects with her Devil Fruit, the Soru Soru no Mi or Soul-Soul Fruit using others' life force or even her own. Big Mom controls three special Homies that function as her primary weapons in battle: Napoleon, her sentient hat, can turn into a giant blade, Prometheus is a living ball of fire, and Zeus and later Hera are living storm clouds which generate lightning.
