Critical Rift

Bill Cipher is a scientist who has come to Gravity Falls, Oregon, to study the huge concentration of supernatural activity in and around the town. He and his colleague, Ivan, are searching for interdimensional rifts to learn more about their origins. Upon finding one, Bill is ripped from his mortal body and sucked into the rift. Ivan, now scarred, is left alone in Gravity Falls, until he comes across some fellow scientists.
