Comments:
Later reprintings of this story place the time as 2496 rather than 2966, presumedly to avoid conflicts with the Legion of Super-Heroes who exist in 2966.

This is the second in a series of Superman of 2965 tales. This story is continued in part from the second story of Superman #181 and continues in the first story of Action Comics #339.

Synopsis:
Muto returns with a plan to kill his greatest enemy, the Superman of 2966. Muto raids a planet containing the greatest weapons in the universe. Superman falls for a decoy which lures him away, allowing Muto to escape. Superman tracks Muto and spots him starting a flood. The rushing water endangers three children. Superman tries to rescue the children, only to discover that they are androids. The flood waters engulf Superman exposing him to his only weakness, atomic fallout in the sea water.
