Jaffanie (Jake/Stefanie) is another major one, mainly fueled by the actors' own actions behind-the-scenes.
Anvilicious: The Black History Month episode has shades of this not only for black heritage but also a little bit of women's heritage. Lampshaded when an actual anvil falls.
Award Snub: Averted. While it only received one nomination at the 2012 Kids' Choice Awards (Jake Short for Favorite TV Actor), he won against quite modest competition (He faced Ty Burrell and Tim Allen, two middle-aged actors, and Alex Heartman of the male-targeted Power Rangers — and with the KCAs being heavily female-skewed, his odds were slim, at best). Favorite Show and Actress are maybe year or two down the road, but Favorite Sidekick should have been Sierra McCormick for Olive. Who got nominated? Jennifer Stone, Jerry Trainor, Nathan Kress and Jennette McCurdy (who won for the 2nd time in a row). Really? Three sidekicks from the same show? A show that the main protaganist seems the be the true sidekick to Jennette McCurdy. It was as if NICK paved the way for her win by not putting anyone who posed a threat. Adding Gibby to the mix would've made much more sense, but he could've beat Jennette. YMMV on Sierra winning it, but she definitely deserved recognition.
It's like they gave Jake Short the win to make up for it. But it wasn't even formally presented, just announced.
Paisley is hugely popular, especially for a supporting character. Granted, that probably has less to do with the character itself and more with who plays her.
One would imagine that the most popular character of all would be Chyna, whom the show is written around, or at least Lexi for being pretty - but apparently, it's actually Olive. Being so Adorkable is a big reason for her popularity. However, she's become rather polarizing in the third season, as her adorkable nerd personality started mutating into a rather neurotic know-it-all and she did surprisingly mean things to others, especially Fletcher.
Genius Bonus: In "Some EnchANTed Evening", Gibson recalls an incident involving a cheerleader named Samantha Herkimer. Those familiar with the sport of cheerleading will recognize that the character is named after Lawrence Herkimer, the founder of the National Cheerleaders Association.
The episode "ScavANTger Hunt" features a lot of references to the Star Wars franchise and George Lucas - right around the same time Disney (owners of The Disney Channel) bought the Star Wars franchise and LucasFilm Licensing lock stock and barrel. Further interesting as it's a case of this trope before the episode actually aired.
The episode EndurANTs has Billy Unger guest-star as a rival to Fletcher. He is also Jake Short's future costar on Lab Rats: Elite Force and their characters are (sometimes) also rivals.
Just Here for Godzilla: A fair amount of males are only watching for Lexi & Paisley (and, to a degree, Chyna & Olive).
The end of "You're the One That I wANT" has Lexi playing the male lead to Chyna's female lead. They sing a romantic song somewhat similar to "Summer Nights" that was originally supposed to end with a kiss. They don't kiss, but still...
The Idol Singer episode has Chyna singing "You are beautiful, no matter what they say..." The fact that Lexi mistakes this as Chyna singing the song to her is played as a joke, but the scene is seriously played out like Chyna is singing it to Lexi!
Hashimoto and Winter Maddox crossed it after taking over the company by turning the ANTs into unpaid employees and forcing them to sleep in tubes.
Winter (or rather, her monster-verse equivalent) crosses it even moreso in "Mut ANT Farm 3" when she forces mutant-Chyna to use her Medusa powers to turn other students into stone, so that they can be broken down into aquarium pebbles by other students under slavery.
MST3K Mantra: A fairly common complaint people have against the show is that Olive is the only one of the ANTs whose gift would actually help her do well academically.
China Anne McClain and Sierra McCormick both appeared on the Hannah Montana episode "Welcome to the Bungle", both playing confused and distraught audience members on a talk show that were fans of Hannah that mindlessly did whatever Hannah said she liked, and whose parents were concerned enough about the mixed signals Hannah gave the kids to bring them to a talk show featuring Miley so their daughter's could put her on the spot.
Stefanie Scott's appearance in "Beethoven's Big Break" might also count since it was her first film role and she was roughly the same age (if not younger) as the ANTs are in-universe.
Gibson frequently draws complaints of being an annoying Manchild, which also applies to Zoltan (albeit to a lesser degree).
Angus has been turning into one, due to his Fat Bastard traits and being used as an outlet for fat jokes. The fact that he's replaced the far more likable Camerondoesn't help. He's also a borderline Creator's Pet. No one ever calls him out for being rude, he gets away with being a jerk, and in a Season 3 episode he is related to royalty.
It certainly doesn't help that the first episode centered around him in the 3rd season had him acting like an entitled, egotistical jerk. Some people wished that Chyna should have just let him crash and burn.
Tazmanian Neville is hated for being a clueless Jerkass and for taking credit for Fletcher's Moment of Awesome and belittling him in front of live TV.
They Wasted a Perfectly Good Character: Fletcher's talent is rarely used in the series, and if so, it's generally unimportant. The traits that the show most focuses on is his Butt-Monkey status and his ditziness. In a lot of plots, he's rarely even used at all for anything other than humor.
Cameron. He's acknowledged to have absolutely no talents other than playing Donkey King (stated in the above quote). It's also revealed that he enjoys his job as the school announcer because it's the one time a day that people are willing to listen to him. Also everyone calls him short.
Oh, Fletcher, Fletcher, Fletcher. He is called dumb by everyone and it's always made fun of that his talent (art) is downright useless. The few times where his art is valued is by a guy who was implied to be high on cologne fumes and by his idol who takes Fletcher's gift and claims that it's his art. His Moment of Awesome in the Australia episode is also downplayed by Tazmanian Neville, who claims that he rescued Fletcher from the outback and belittles him in front of what is most likely a national audience. If Secret AgANT is anything to go by, he has a 0% Approval Rating in the entire country. Damn, he makes Freddie Benson and Robbie Shapiro look like Leprechauns.
That whole 0% Approval Rating thing from Secret AgANT has been revealed to be false in FinANTial Crisis due to The Reveal that Kennedy is actually not a debate prodigy but actually Hashimoto's Daughter and she made it all up. On the other hand, it's also revealed she didn't love Fletcher after all.
