The origin of Superman, from the end of Krypton to him dealing with his first criminal threat.
- A.I. Is a Crapshoot: Brainiac knows that Krypton is going to explode, but covers it up in order to save itself without having to divert attention and resources to saving anybody else.
- Badass Normal: Jor-El, who is basically the same as a normal human, starts the episode escaping a giant monster and escapes the Brainiac decived police to evacuate Kal-El from the doomed planet. It seems awesome runs in the family.
- Be Careful What You Wish For: Krypton accepting Brainiac's word without questioning.
- Captain Obvious: Perry points to a picture of Superman and asks Clark and Lois who he is. Jimmy (listening in) helpfully suggests that it looks like a man flying.
- Clasp Your Hands If You Deceive: Luthor does it near the end.
- Cultural Rebel: Jor-El.
- Decoy Getaway: Sul-Van leads the police away while Jor-El makes the final preparations and launches the rocket.
- Doorstop Baby / Moses in the Bullrushes: Discussed and lampshaded as the Kents tell Clark about how he was found.
Jonathan Kent: Do you know how some babies are found in baskets? (reveals the rocket) Well, this is how we found you.
- Death by Origin Story: Jor-El, Lara-El and the entire planet of Krypton.
- Doomed Homeworld
- Heroic BSOD: Clark after he finds out about his true nature.
Clark: It's not true... I'm not a freak... I'm not... I'm NOT!
- Ignored Expert: In this incarnation, Jor-El is discredited by Brainiac, who was buying some time to save himself.
- It's All About Me: Brainiac's justification for not revealing Krypton's fate.
- Jerk with a Heart of Gold: Sul-Van, Lara's father, who despite doubting his son-in-law, is ultimately the only Kryptonian who took his concerns seriously, if only due to caring about his grandson's future.
- Powered Armor: Luthor unveils a new prototype, which is promptly stolen. The "theft" is actually a cover for an illegal arms sale to Kaznia.
- Shout-Out: One name Martha considers giving Clark is Christopher, no doubt in honor of Christopher Reeve, who played Superman onscreen.
- She also considers "Kirk", possibly a reference to Kirk Alyn, who played Superman in a 1948 serial.
- This Is Gonna Suck: Just before Krypton gets destroyed.
Kryptonian: Not another one [earthquake]...
Sul-Van: No, the last one...
- Too Dumb to Live: Jor-El was right that Krypton's blind faith in Brainiac would doom them all, as he'd intentionally lied to get time to save himself.
- You Are Too Late: To save everyone on Krypton, since the planet only has a few hours remaining.
