Adventure 287 (Aug 61) begins a 2-part Superboy story, spending its time by giving an extended backstory to Dev-Em, the Knave from Krypton, in his debut appearance. As a result, Superboy is really only a supporting character in this tale.
Dev-Em and his parents live next door to Jor-El and and Lara, and he is shown as a rowdy and criminally irresponsible teenager. He almost runs over baby Kal and Krypto with his car, steals, vandalizes, and even breaks into Jor-El’s home. Though it’s because of that that Dev and his parents wind up surviving the destruction of Krypton.
After reading Jor-El’s notes, Dev converts a backyard bomb shelter (ah, peaceful Krypton, where families have big bomb shelters in their backyards), preparing it to block the deadly kryptonite radiation that Jor-El theorized.
Dev-Em convinces his parents to go into suspended animation with him, but awakes before them. He must be near Earth, because his powers have kicked in, and by using super-vision he spots Kal on Earth, receiving a trophy as Superboy, and decides to head there and get rid of him.
The story concludes in the following issue.
After being yelled at by Perry White for not getting any good stories, Jimmy sees a spaceship, apparently being boarded by Superman, and stows away. Of course, it was not Superman, it was Bizarro, and Jimmy winds up on Bizarro World.
He starts working at the Daily Htrae, under Bizarro Perry White, but has even less success than he does on Earth, as he cannot grasp what makes news on Bizarro World.
It’s a fun little tale, but again I find it curious that Otto Binder wrote the serious Sueprboy story in this issue, and Jerry Siegel the silly Bizarro one, rather than the other way around.
Jimmy just wants to head back to Earth, but as long as he keeps bombing out with his news stories, the Bizarros have no intention of returning them.
Finally, Jimmy creates a Bizarro version of himself, and is punished by being sent back home.
