- Matter-Eater Lad takes a big bite out of the Emerald Eye of Ekron, finally defeating the Emerald Empress (otherwise the mistress of Villain: Exit, Stage Left!) permanently. However, doing so put him in a coma for most of the season.
- Bouncing Boy showing his leadership potential during "Chain of Command". He somehow displays awesome powers of strategy, saves an entire planet from storms, and even gets kissed on the cheek by Triplicate Girl (AKA the girl in the striped miniskirt). This rightfully earned him his Darkhorse Victory to become the leader at the end of the episode.
- Slightly negated by the fact that nobody ever mentions this again in season 2.
- In his debut episode, Timber Wolf calls out his father on his crappy treatment of him and others, then proceeds to trash his lab in a fury (which includes punching a hole through solid metal to tear out the wires and ripping out an operating table from the floor and throwing it at a bunch of computer screens). Earlier, he roars at the animal test subjects who looked ready to maul his Dad. Given how he was acting at this stage, this was so richly deserved.
Dr. Londo: "Not even intergalactic law can touch me, and why would they? My work is a gift, I create life!"Timber Wolf: "What you create is suffering and the forest out there is filled with it!! Children expect their parents to protect them, the only thing I've ever been to you is a science experiment! Your own son!! (proceeds to virtually destroy everything in the lab. After he's done, he gives his father an over-the-shoulder cold glare) ''Never again." (cue his shocked father kneeling in the ruins of his burning lab)
- The death of Ferro Lad in destroying the Sun Eater is both awesome and a Tearjerker. Superman's response to its master afterwards is even better.
Ferro Lad: "Long live the Legion".
- Watching the Legion of Substitute Heroes get their act together and defeat Starfinger definitely counts. It just goes to show you that the underdogs can come out on top, even if no one believes in them. Their powers might not have been as cool or as strong as the rest of the Legionnaires', but when it came time to step it up, they made a pretty good team.
- When Brainiac 5 beats up Brainiac 1.0.
- Brainiac 5: Now I am going to tell you one last time. Get. Out. Of. My. Head!
- Added awesomeness by punctuating each word with a blow.
- Imperiex and Kel having to work together to save a child ends with both of them firing lasers at what can only be called Cowboy Terminator from the 4th millenium. Can you guess what happens?
- Just this: Corey Burton returns as Brainiac 1.0.
