Bill's friends are antagonists from the three part series finale of the Disney XD show, Gravity Falls. They all appear to be different types of interdimensional beings who befriended Bill due to their love of chaos, destruction, and heinous criminal activity. It is unknown if they all originate from a single universe or were brought together from across the multiverse, though regardless of which of these is true, they all seem to have been brought together by Bill Cipher . When Bill gained physical form in the 3rd dimension, his rip in the fabric of space-time allowed the troublesome group of demons to enter, as well. They all appear to have no other desire than to cause mass chaos and have fun at the expense of others. During Weirdmageddon Part II, it was revealed that they, along with Bill, were being held in Gravity Falls by the town's natural law of weirdness magnetism. During the series finale, the monstrosities were sucked back into their own worlds after Bill's defeat.
