X-Men: Omega Point
Lucas Bishop is a homeless man with clear psychological problems. He believes he is from the future. He seeks out the X-Men, saying that they are legends in the future he comes from. He warns them that on April 4, 1968, Dr. Martin Luther King, Jr. will be assassinated. According to Bishop, this will lead to riots across the country. He describes a nightmare scenario some fifty years later, with a staggering percentage of the U.S. population in prison — falling even harder on black men — and police departments even in small towns outfitted with military equipment to squash any protest or dissent. Bishop urges the X-Men to avert this dystopian future by saving Dr. King.
