Good Bye Charlie
Gabe is known for being a troublemaker, sarcastic at most times, apparently lazy, and insults his parents and his siblings, but he can be a crybaby sometimes. But he is also known as a cunning and determined. In one episode, Gabe was "in love" with a girl from school and even tricked her parents so they could be together. He always tricks PJ into things. Gabe is a troublemaker, but there is a brighter side of him!! Despite his usual troublemaking and pranking, it is shown in Sun Show, Part One and Part Two that Gabe is capable of doing good things. This is shown when he promises in the helicopter crash that, if God let him live, he would do something good. Immediately, the helicopter pilot, after being in a narcoleptic episode, wakes up and takes control of the plane. Gabe also has a sort of Machiavellian side to his personality, known to switch sides, and joining anyone if he felt it could benefit him, for example, one occasion he gave his mother the information she required to spy on PJ, then sold PJ the knowledge that his mother was spying on him. In another, he told his mother and Mary Lou Wentz how the girls tricked them, and encouraged them to go after them, only then to warn the girls, so both of them would owe him a favor. In season 3 he is into a lot of girls and has a lot more crushes. He is described as sharp as a tack by his Dad (Bob).
He is also a member of a basketball team that his dad Bob Duncan coaches, and even through his negative reputation at school Gabe was voted class president ("Duncan's Got Talent"). He worked well with Jo on their volcano science project.
Gabe often makes fun of his parent's age and weight. Once when Gabe was not allowed to make fun of Bob's weight for a week, Bob concluded that that's never going to work. Gabe wrote many fat jokes about Bob in a week, which Amy liked. Gabe still loves Bob anyway (“Gabe's 12-½ Birthday”). He apparently tricks Bob into doing his projects and doesn't like the fact he's losing weight.
Gabe relies on Amy to do tidiness work for him. Gabe often calls her to get the door, and once, implies that she makes his bed every morning ("The Curious Case of Mr. Dabney", "Duncan vs. Duncan"). The two do get along in other ways, as they have similar personality traits, Gabe told Amy that he must get his evil genes from somewhere, Gabe was scared of Amy in (Up a Tree) but isn't anymore. When Gabe helps Amy spy on PJ's buddy page, Gabe loves Amy and seems to be more of a mommy's boy. Gabe is also known to let Amy know when Teddy or PJ are up to mischief.
Gabe does somewhat love PJ, but often manipulates him to help him get money and do work for him. Gabe is very close to PJ, although he makes fun of him a lot for not being "very thinky" (because Amy won't let him call PJ "stupid").
It is known that he takes pictures of Teddy's activities with her boyfriends to embarrass her in front of her schoolmates ("Meet the Parents"). Gabe helped Ivy come up with the nickname GG (goody goody) because Teddy is well behaved at school. Charlie walks in and calls her GG ("Ditch Day"). Even though Gabe can be rude somehow he seems to turn out good at the end.
Gabe and Jo are frenemies. They have a relationship that is very complex. Having romantic feelings yet also several times of hatred. It is unknown what they currently consider there relationship to be. However, since Jo no longer appears on the show, it's unknown.
It seems that Gabe will have a better relationship with Toby than he did with Charlie when she was a baby. It was seen that before he was born, he said he wanted a baby brother to pick on. When it became known that he was indeed a boy, Gabe was excited, and his mood was even better when it was revealed that his name was Toby, the name he suggested for him in Name That Baby. He suggested that name because it's "cool". He also starts his own video diary for him based after Good Luck Charlie that he calls "Good Fortune Toby". In Baby Steps when Toby was flying, he yelled, "Nooooo!". Also, in a lot of occasions Gabe almost agrees to things that he doesn't want to, because he's influenced by Toby's adorable face, as in All Fall Down when Amy was telling Gabe that Toby is moving into his room he said no, but looked at Toby and said "oh" as how cute Toby was but then says "stop it Gabe!" to himself so he does fall for Toby adorableness.
Emma is a girl Gabe starts dating in Team Mom. Emma believes that her father, Randy, and Bob are best friends, but Gabe confesses that Bob does not like Randy because he is way too clingy and has horrible manners. They get into an argument and, eventually, Emma breaks up with him, but Gabe does not seem to mind at all.
The two have a strong rivalry, Gabe delights in pranking, tricking and generally annoying Mrs. Dabney, while Mrs. Dabney openly shows disdain and dislike for him. It's mentioned in one story that Gabe is the reason Mrs. Dabney is mean and grumpy. He is currently in a relationship Mrs. Dabney's granddaughter, Lauren Dabney and never kissed.
Lauren is Mrs. Dabney's granddaughter and she and Gabe are currently dating. In Futuredrama, Gabe and Lauren break up because Teddy gives Gabe bad relationship advice. They get back together after Lauren learns what happened.
- Gabe's age has been a discrepancy in the show's continuity. While it is known that all characters develop and age in the same time as the real world, Gabe has been referred as 10 and in third grade at the beginning of Season 1 ("The Curious Case of Mr. Dabney", "Dance Off") and 11 in November ("Teddy Rebounds"), Gabe is in fifth grade ("Teddy's Bear") and even an entire episode on his 12-½ birthday ("Gabe's 12-½ Birthday"). It is mentioned that he is 13 in Season 3 in episodes, Name That Baby (when Amy said he's 13), Wentz's Weather Girls (when he said since he's 13 he doesn't need help from his mom) ", "Welcome Home" (when he told PJ , "Don't rush me, I'm not 12 anymore!") and Special Delivery when Jake said "we're teenagers now, we're suppose to be rebels!")
