Legion of Super-Heroes (TV series)/YMMV
- Angst? What Angst?: Lightning Lad loses his arm. He doesn't mind.
- Complete Monster: Dr. Londo, Imperiex, the Controllers, and Brainiac 1.
- Die for Our Ship
- Some Timber Wolf fangirls hate Ultra Boy because he's Phantom Girl's boyfriend in the comics.
- Also, some fanfic authors can't stand Shrinking Violet because Brainy seems to like her.
- Fashion Victim Villain: Imperiex is supposed to be the Big Bad of the show's Darker and Edgier season... and he has a silver ponytail that doesn't quite match with the rest of his ensemble.
- Foe Yay: Drax's final scene in his episode has him a little too physically close to Superman for comfort.
- Moe: Brainy. YouTube commentors can stop talking about how "freakin' adorable!" he is.
- Phantom Girl as well.
- High Octane Nightmare Fuel: "Trials"
- Ho Yay: Brainiac 5's fanboy man-crush on Superman. Given an honest-to-gods Lampshade Hanging by Timber Wolf in the second season premiere: Behold. (The video comments are also...choice.)
- The Scrappy: Cosmic Boy, due to the fact that he is portrayed as a Good Is Not Nice example of Lawful Good, especially in the second season where he appeared more frequently with Jerkass tendencies.
- Too Good to Last: It's the sad, sad red-headed stepchild of DC animated adaptations, it's the least-remembered one made under Warner Bros. animation's banner. And it's pretty good, as well.
- Tough Act to Follow: This series was greenlit along with Ben 10 to replace Teen Titans, right down to having Derrick Wyatt as the head character designer. There's no way it'd be able to avoid comparisons!
