Superboy's nonexistent relationship with Superman takes its toll on him, as he ignores Black Canary's training and becomes more angry and irrational. Things get worse when the team faces Professor Ivo's Amazo, a threat with which even the Justice League has trouble. Meanwhile Batman advises and tries to convince Superman to accept Superboy as his son.
This marks the first appearance of Batman and Superman in their civilian identities as Bruce Wayne and Clark Kent respectively.
