The Bludger is a round, jet black ball that is featured in the game of Quidditch. Bludgers follow random paths and can ruin the brooms players fly on and even injure players. The only people able to hit these objects are Beaters who carry bat-like objects to hit the Bludgers with in order to protect teammates and send the bludgers off towards opponents. Bludgers known as "rogue Bludgers" have been banned from all competitive Quidditch as they chase after a single player relentlessly. All Bludgers are currently made of iron to withstand the force of the bats Beaters use.
