Synopsis:
Superman is exposed to Red Kryptonite causing him to split into two separate individuals. One is his Clark Kent identity which has no powers; the other is Superman which has powers, but no memory. The amnesiac Superman decides he does not want to be merged back with Clark when the effects of the Red K wear off, so he tries to stay away from Clark, even exiling Supergirl and Krypto to the Phantom Zone to prevent their involvement. Clark eventually succeeds in merging with his double, because the Superman half miscalculated the amount of time that had passed.
