- Alternate Character Interpretation: Just about everyone. For example, Death is kind of a material girl who's bored by Thanos trying to impress her, but the moment she sees Deadpool flying a ship loaded with gold, she's right into his arms.
- Big-Lipped Alligator Moment:
- A few of Stan Lee's cameos, such in Star Trek where he's teleported into the transporter room, dressed in a tuxedo and singing "Hello, My Baby!", or in the second Iron Man episode, where he's sitting on a tiny planet in outer space.
- Captain America somehow pulls out and blows a conch shell when Bruce Banner Hulks out in the bowling alley.
- "Funny Aneurysm" Moment: Ant-Man's episode came out when it seemed like the producers of his first movie were also having a bad day or two — CineFix posted the teaser one day after Edgar Wright quit the project, and released the episode on the same day that Adam McKay turned down an offer to become the new director.
- Hilarious in Hindsight:
- After the release of Iron Man 3, it seems ironic that Iron Man's second episode makes the Mandarin resemble Ben Kingsley. IM3 exposes Kingsley's character as an imposter of the Mandarin.
- Stan Lee's cameo in the Justice League episode gave a Stealth Insult to their movie languishing in Development Hell, insincerely assuring the League that they'll "...get it right someday." Four years later, the Justice League movie finally hit theaters, but to disappointing critical and audience reception. Four more years later, HBO Max's Zack Snyder's Justice League gave DC a second, better-received chance to prove they could "get it right".
- Magneto shooing away Quicksilver in the Days of Future Past spoof was supposed to be a Take That, Scrappy!, but Quicksilver ended up becoming an Ensemble Dark Horse after the movie's premiere. Now, it can seem like a spoof of the X-Men wasting chances to use his Story-Breaker Power.
- One of the characters who cameoed in the Guardians of the Galaxy short becomes a recurring character of the Guardians of the Galaxy movies. In the commentary (also released before the first movie), Junaid explains his Bad Days cameo with simply, "...because he's weird." The Bad Days crew also correctly predicted a cameo by some Slither slugs, and another celebrity showing up to sing seems to unintentionally foreshadow Guardians of the Galaxy Vol. 2.
- Nausea Fuel: The Vomit Indiscretion Shots.
- Seasonal Rot: Season four disappointed viewers who thought the animation quality declined without Junaid and Davor. The only episode released from that season, Glass, also runs so short, that it doesn't boast as many funny gags or clever references as the best shorts from the first three seasons did.
- The Woobie: Most of the superheroes, but Bruce Banner especially. His episode might as well be titled Bad Life.
YMMV / Bad Days
