Superman #20 1988

Superman #20, part one of "Superman Black," is a key "Superman Reborn Aftermath" tie-in. The story sees the Kent family contemplating a move from Hamilton back to Metropolis, but an unknown force resists their departure. Simultaneously, Batman and Robin investigate a troubling development: Superboy, Jon Kent, is inexplicably losing his powers. This issue is notable for its direct continuation of the significant "Superman Reborn" storyline, further shaping the Man of Steel's re-established continuity and focusing on his son's evolving abilities.
