- Ensemble Dark Horse: Rotgut is very popular for being such a downright hilarious Laughably Evil Minion with an F in Evil.
- He Really Can Act: Unidentified Flying Superhero was Mark's moment. Before that, some fans were convinced that Tom Wansey knew what he was doing.
- Idiot Plot: Rick wants to take over the world because he lost his previous job at a video game company for his wild claims that he had a way to bring game characters to life. To get his revenge he implanted his special program in one of the copies of the Ace Lightning game that happened to end up in Mark's hands, and the rest is history. All that could've been avoided if he'd simply demonstrated proof of his claim, which he obviously could've supplied if he'd seen a need to. Then Rick would've been hailed as a genius and become indecently rich, with no need of world-threatening shenanigans.
- Narm Charm: Mostly because Ace is such a blatant parody of superhero stereotypes and yet so utterly believes in them. The human characters acting also bounces around this category a lot. Especially Mark. You really do either love or hate it.
- Lady Illusion's death hops into this category for many fans, especially when you think about it a bit and realize she's not just pulling a bog-standard HeroicSacrifice; she's also finally breaking entirely from the programming constraints that have been messing with her for the last three seasons. Excluding Kilobyte (who never cared in the first place and wasn't programmed with the exact same limits) she is the only character out of all the CGI to actually definitely do this. Everyone else either made the same choices they would've made anyway, or are still in the dark.
- Squick: Oh boy...
- Kilobyte's tentacles. Utilized for power drainage. This is usually a bit... graphic.
- Lady Illusion and Lord Fear are a couple for most of the first series (and yes they behave that way), right? He's a sentient skeleton. Ew.
- Pigface's, er... snot attack. Poor Heather gets a faceful of it, once.
- The Woobie: Mostly Ace, though Mark has his moments.
- As does Chuck
- And Random Virus. Seriously.
YMMV / Ace Lightning
