This work contains examples of the following tropes:
Acquitted Too Late: Narrowly averted in "Superman's Busy Day." The Man of Steel just barely manages to get to the gas chamber in time to liberate the innocent man and show the proof of his innocence to the bystanders.
Anticlimax: the ending of "Jimmy Olsen vs. Darkseid" (see also Covers Always Lie). Seconds after Jimmy breaks Superman out of Desaad's bindings and reverses the body swap, the lord of Apocalips himself shows up. The two heroes brace themselves for a battle, only for Darkseid to tell them he doesn't want to fight Superman now and let them go home.
Bad Future: Mxy convinces the teenaged Superman that this will result if he takes up the superhero path. Instead, it does because he doesn't.
Be Careful What You Wish For: The series ran a comic with that name, about the Man of Steel's interactions with a girl who wishes she could meet him and her life would be more exciting. Both of these wishes are answered when the media declared her "Superman's girlfriend" and she gets kidnapped by Metallo. (Sound familiar?)
Body Swap: Jimmy Olsen and Superman in "Jimmy Olsen vs. Darkseid." Interestingly, this happened as a result of Kalibak attempting to body swap with Superman.
Call Back: in one comic, Superman delivers the following line: "Of all the cub reporters to kidnap, you had to pick my pal with the signal watch!" Both the watch and Jimmy's title as "Superman's Pal" go back to the animated series episode of the same name.
Numerous villains from the animated series, such as Parasite, Brainiac, Livewire, Mxyzptlk, and Metallo, make return appearances.
Continuity Nod: Krypto the Superdog makes an appearance in "Old Wounds."
Covers Always Lie: "Jimmy Olsen vs. Darkseid." More like titles always lie. Jimmy does not wind up fighting Darkseid, though he does take out Kalibak and Desaad.
Driven to Suicide: "Superman's Busy Day", a man who committed a murder and let his brother take the blame for it.
Enemy Mine: When Supergirl becomes deathly ill, Superman is forced to go to Lex Luthor to help her.
Epic Hail: Jimmy Olsen's signal watch. An odd twist in the 28th comic when Superman has to use it to get Jimmy's attention.
Facepalm: Lois Lane does this in "Jimmy Olsen vs. Darkseid" in response to some of Jimmy's behavior.
Forgot About His Powers: Jimmy-as-Superman forgets that he's invulnerable and therefore it won't matter if he has a problem with flying.
For Want of a Nail: in "Yesterday's Man of Tomorrow", Superman himself. When Mxy convinces his younger self to exile himself to the moon, what results is a horrible world where Lex Luthor is the richest, most powerful man in the world and Lois Lane was killed.
Jimmy-as-Superman: Darkseid? You mean the oversized loser behind you with a look like he just ate a bucketful of angry wasps?
Kalibak(turns around): Master...
Jimmy(tackling him): Hah! Made ya look!
Nobody Calls Me Chicken:in "Eye to Eye", Jimmy thinks that Perry was calling him a coward during his latest chewing-out, and he is not pleased. Later, he puts himself in danger to get a good shot, something Perry said was essential for a good newsman.
Not so Above It All: While she and Jimmy are covering one of Superman's battles, Lois remarks that the populace is treating it "like a cheap prize fight" only to murmur, "Ooh, good one" with the next punch.
Pet the Dog: Mxy feeling sorry for the effects of his meddling with the timeline and setting out to fix it.
Power Incontinence: Jimmy has a mild case in "Jimmy Olsen vs. Darkseid" when Superman's x-ray vision comes on by accident.
Sympathy for the Hero: Mxy, of all people, reacts this way in "Yesterday's Man of Tomorrow" when he sees how miserable everyone would be without his nemesis.
What Is One Woman's Life in Comparison?: Lois pulls a rather interesting version of this in "Distant Fires". Having caught Lois, Brainiac demands the ball containing Krypton's memories - last seen in "Stolen Memories". Superman counters with his own ultimatum - let Lois go or he smashes the ball. Lois protests that she is only one woman against the remenants of an entire civilization. Three guesses how the Boy Scout responded to that.
