Synopsis:
While Batman and Robin stop some crooks in an armored vehicle, Superman stops a strange meteor which Batman then takes to the Bat-Cave. Later, Superman becomes weak and somehow spins himself into a cocoon. When he emerges his appearance has altered as have his powers. His memory has gone as well.

Batman takes him to the Daily Planet to try and restore his memory. It returns briefly allowing him to explain that the meteor was responsible for the change. Batman has to rush off with Robin to stop some crooks.

When he returns he takes the alien Superman to a cave. He believes that it is a phony, but it is the real Superman who has recently escaped a trap. The two heroes plan a trap of their own for the real crooks.

An alien criminal, Khalex is behind the hoax. He has super powers himself, but the meteor weakens him. When he gains powers he realizes that Batman must have destroyed the meteor. The alien and his Earth criminal friends begin a robbery spree only to be confronted by Batman and Superman. The alien loses his powers when the meteor is returned to Earth, allowing the heroes to catch him and his allies.
