Superboy? That's right. When evil scientist Ira Quimby (better known simply as I.Q.) tries to throw Superman back to prehistoric times and erect a "time shield" to keep him there, he misplaces a decimal point and tosses him back just 15 years. Because a person can't co-exist with himself in the same time, Superboy is thrown into present day.
So a veteran Batman and an inexperienced Superboy must team-up to figure out what is going on. The actual plot of this story is fine--written by Mike W. Barr and drawn by Jim Aparo, it progresses and climaxes quite satisfactorily.
But what makes this story really fun is the interplay between Batman and Superboy. On several occasions, the Dark Knight has to deliver a stern lecture to young Clark about using his powers more effectively. For instance, he has to explain that it was a mistake to use heat vision on a thug's gun, since that detonated the gunpowder and tossed shrapnel about that might have hurt an innocent bystander. Instead, he should have just melted the bullets in mid-air. A chagrined Superboy replies "O-okay." Batman also has to give young Clark a “Is this how your parents trained you?” lecture to keep the Boy of Steel on track after he stumbles across the fact that the Kents have died.
We also get a brief glimpse of Superman back in his bedroom in Smallville, listening to Pa Kent call out that breakfast was ready. Unable to face seeing his parents while knowing they will soon die, he immediately flies away. It's a brief scene, but sincerely emotional.
By the early 1980s, the mythology of the DC universe had become quite complex. Within a few years, the editors at DC would decide it was too complex and we would be given the first of many DC Universe reboots with the Crisis on Infinite Earths mini-series. Many comic fans still sincerely argue about whether this was a good or bad idea, but the complexity of the original continuity did have its advantages. In the case of this issue of "The Brave and the Bold," it allowed writer Mike W. Barr to take a law of DC Comics physics (you can't co-exist with yourself during time travel) and combine it with an established part of the Superman mythos (his career as Superboy) to create an entertaining and rewarding short story.
