Determinator: In Big Time Movie, he gets punched in the ribs by one of Atticus Moon's henchmen, and gets up as if it were nothing. Keep in mind, that particular henchmen a mallet made of silver for a hand.
Disappeared Dad: Since Kendall and Katie set dates for their mom, it's assumed their father is either divorced or gone. Nobody talks about him.
Butt Monkey: When the guys are worried that Wayne Wayne will have someone kicked out of the band, James remarks that he thinks it'll be Logan... Whilst crouching right next to him. Later, Gustavo and Griffin remark that they thought Logan would be the one kicked out of the band, Griffin going so far as to use the intercom so that Logan would hear him.
Logan was also sat on by Gustavo and ran over by a horde of fangirls. Boy can't catch a break.
In "Big Time Break", Logan goes through a lot of trouble just to get a lecture from his favorite math celebrity teacher just to find out she's a crazy feminist and, latter, getting beaten up by a bunch of girls.
In "Welcome Back Big Time", Logan does several weeks of school work in a day - not just his own, but the rest of the group's too. All James and Kendall do is something very minute so they could claim the work was their own, but Carlos just signs his name.
Somehow their teacher doesn't put 2 and 2 together when Carlos' project includes a working laser.
In "Big Time Moms," it is revealed that Logan's real name is Hortense, but James' mother makes him change it.
In Big Time Movie Logan gets shot by tranquilizing dart guns... three times.
In "Big Time Pranks", the guys hold a prank contest among all of the Palm Woods tenants and Logan is the first one to be disqualified. Funny thing is, nobody even pranks him, he actually pranks himself.
Crazy Jealous Guy: He can be this for Camille. In "Big Time Secrets", he started stalking Kendall and Camille because he thought they were secretly dating. He literally became Ax-Crazy and started chasing them with an ax-shaped guitar.
The Ditz/Brainless Beauty: Downplayed. He falls pretty easy on scams (for example the fan who ended up kidnapping and locking him in a basement) and isn't very academically smart, as he only cares about his looks.
Dude Looks Like a Lady: Lampshaded in "Big Time Christmas." In the animated music video with Snoop Dog, the band is depicted as squirrels, but James is the only one with eyelashes.
Kendall's younger sister. She is dangerously clever and definitely wise beyond her years. Always thinking of money making schemes. Regardless, there are times when she acts like a normal ten year old girl, but is 100% confident in her plans.
Disappeared Dad: Since Kendall and Katie set dates for their mom, it's assumed their father is either divorced or gone. Nobody talks about him
Foil: To both Kendall and her mom. She is the only one in the family who adapts quickly to the competitive and business-focused Hollywood, while they keep their Minnesota lifestyle views. Still, they are very close as a family and can work their way out of any situation.
Guile Heroine: She is equally as ambitious and manipulative, but her heart is in good place.
Improbable Age: One episode has her put in charge of the label, which she is exceptional at.
Leitmotif: A mockingly sweet melody. Also used with some other characters, however.
An In-Universe actor, one of the most eccentric characters on the show and Logan's on-again/off-again girlfriend. She constantly acts out her roles as practice and has a tendency to slip too deep into character
Played by Denyse Tontz as Jennifer 1, Spencer Locke/Kelli Goss as Jennifer 2, Savannah Jayde as Jennifer 3
Three beautiful but high-maintenance girls of the same name. Notorious around the Palm Woods for their slow-motion entrances and rejecting any guy without a movie deal or a top ten single.
Alpha Bitch: The three of them have ruled Palm Woods by being mean to the newbies to "mark territory".
Girl Posse: So much that they can't keep balance if the group is incomplete. When Jennifer 2 was absent, they completed the trio by replacing her with Carlos.
The Fashionista: The three of them. Averted when Jennifer 1 is separated from the others, Carlos is told that the three of them help each other, reason why she was acting strange during their prom date.
Hidden Depths: Even thought they are snobby and divas, they do have soft spots for Carlos.
A girl who moves into the Palm Woods after Jo leaves. There was some romantic tension between her and Kendall, but it faded when Jo comes back. As of season 4, she's back, and is developing romantic tension with James.
Asian and Nerdy: Her parents think that she is this as a classically trained concert violinist. In reality, she averts this trope.
Freaky Fashion, Mild Mind: Lucy has dyed red streaked hair and dresses like a stereotypical rocker chick, but is really quite friendly.
Huge Guy, Tiny Girl: With James in season 4. At 5'3 Malese is the shortest of the adult female cast and at 6'1 James is the tallest of the male.
Stage Mom: His mother tries to get him any kind of castings and he hides from her all the time.
Foil: To Katie. He tries to avoid celebrity job, while Katie loves the Hollywood business.
Rocque Records and associates
Played by Stephen Kramer Glickman
The boys manager. A disgraced music manager from the 90's who is trying to get back on top. He refers to the boys as "dogs" and nearly every episode has him writing a song.
Bad Boss: He is constantly screaming at people. How bad of a boss? With only the mention of his name, Nicole Scherzinger threw a telephone at him for "creative differences".
The Chew Toy: He gets beaten up, suffers from frequent rage induced high blood-pressure (courtesy of Kendall) and he once even got hit by Snoop Dog's limousine, getting away with few bruises and a lot of bandages
Genre Savvy: His first reaction to Mercedes' admission of facts was to verify with the boys.
Griffin: Is all that true? Because she lies. A lot.
Heel-Face Revolving Door: And around and around and around he goes! One episode he can be the happy-cuckoolander boss, and the next episode he would want to close Roque Records unless they make more money for him.
Producer of Hawk records and the Big Bad of season one. His motives are to bring down Gustavo and the boys carrer. In the season finale, he tries to get James an independent contract but when the boys get back togehter, he kidnaps them and ends up arrested.
Animal Motifs: He tries to make the Hawk his signature style, even thought nobody likes the "Caw!!" schtick.
A girl from Minnesota who was also in the boys' school and attended Gustavo's audition. Her dream is to be "the next Gwen Stefani". She is also known to be accident prone in a whole other level.
The Bus Came Back/Ascended Extra: She started as a minor character who was rejected in the auditions of the pilot. She returns a season later in "Big Time Fans", as Carlos promised to help her in her singing career.
Born Unlucky: The boys know Jenny had this since kindergarten. James needed stitches in his arm for a papercut.
The Smurfette Principle: When she joins Death Smash. The other two members are big badass rockers (who secretly hated their original leader for making them smash guitars and fake their accents).
Played by Erik Estrada and Jill-Michele Melean
Carlos' parents. Both of them visited Carlos at Palm Woods, although in separated episodes. They have a very close relationship. Carlos' dad is a police officer and takes his job very seriously, maybe a little too much.
Bumbling Dad: He takes his job very seriously, even to apply it on his son's daily tasks.
