Characters / Good Luck Charlie

The Duncan Family (in order of billing):

Teddy Duncan
Portrayed by: Bridgit Mendler
A 15-year old high school sophomore and, until the new arrival, the middle child of the family. She records a series of video diaries for her baby sister for when she's older, which form a substantial portion of the show's narrative (and where the title comes from). She cares a great deal for her family, even if she isn't great at expressing her affection for some of them, and has a special attachment to her baby sister, Charlie. So far, she appears to be a good student, and is obsessed with most of the things typical of girls her age, preeminently boys.

Amy Duncan
Portrayed by: Leigh-Allyn Baker
The 30-something mother of the Duncan family, who works as a nurse at a hospital. The main source of the show's humor and drama is the rest of the family's often-misguided attempts to help take care of the baby as Amy returns to work. She seems like the Only Sane Man but her ego and Spotlight-Stealing Squad mentality keeps her from this.

Gabriel P. "Gabe" Duncan

Portrayed by: Bradley Steven Perry
The sarcastic, often dour 10-year old son, who resents Charlie for having usurped his position as the baby of the family, and thus drawing a good deal of attention away from him. His perceptions seem somewhat justified. Continues the proud Danny Bonaduce tradition of looking nothing like the rest of the family.

Charlotte "Charlie" Duncan

Portrayed by: Mia Talerico, Ava Sambora (Future Charlie in "Futuredrama")
The 9-month old (as of the series premiere, currently 4 years old) newest addition to the Duncan family. She begins the series as an infant, not doing much except make noise, pooping and spitting up. Nonetheless, she's extremely cute, and quickly progresses to new milestones, such as making her first attempts at real English words, and taking her first steps. She is whom the series' title comes from.

  • Annoying Younger Sibling: To some extent, to the point of sometimes being nosy.
  • Aesop Amnesia: In Guys and Dolls Amy tried to help Charlie with her jealousy of Toby, which seemingly worked. Amy pretended to make Toby talk and say that Charlie is his favorite sister. Come Doppel Date however, Charlie wanted Toby to stay in the hotel. Justified in that she's still a toddler, but "Futuredrama" indicates their dynamic hasn't changed since.
  • Character Development:
    • She gets a lot more characterization in seasons 3 and 4. As she grows up, she seems to take after Gabe, who was jealous of her, whereas now Charlie is jealous of Toby. She also appears to be shaping up to be a troublemaker, like Gabe. She's also inherited her mother's ego which has lead Amy and Bob to say she's her mother's daughter.
    • In Duncan Dream House, for the first time, Charlie was actually right about keeping their old home, and even had her own scene where she talks to her imaginary circle.
    • If "Futuredrama" is any indication, she grows up to be more like Teddy.
  • The Cutie
  • Deuteragonist: From Season 3 onward, Charlie is given a lot more character focus, mostly due to her growing up.
  • Evil-Detecting Baby: In "Girl Bites Dog", Charlie bites Spencer because she somehow knows he's cheating on Teddy.
  • From the Mouths of Babes
  • Gender-Blender Name: Charlie.
  • Genre Blindness: Her future self learns this the hard way after getting beat up by 11-year old Toby, since she forgot to wait for the ending tagline of the video diary, "Good luck Charlie!"
  • Little Miss Snarker: She's shaping up to be this in Season 3. This became evident when she picked up the phrase "aw nuts" from Amy.
  • Only Known by Their Nickname: Charlie's real name is Charlotte.
  • Ping-Pong Na´vetÚ: Charlie often appears really smart for a baby, but she'll be the Spanner in the Works if the plot calls for it.
  • Plot Device: Being about 9 months old, she starts out as such. However, thanks to Character Development due to her growing up, there are some episodes where she gets a subplot of her own.
  • Secondary Character Title: The main character is Teddy, who is making a series of video diaries for Charlie to watch in the future, all of which end with Teddy telling her "Good luck, Charlie".
  • She's All Grown Up: Her future self. The present Charlie even lampshades this during the Credits Gag of "Futuredrama".
  • Shipper on Deck: Implied to be this towards Teddy and Spencer.
  • Tomboyish Name: She has a boyish name, just like her sister Teddy.

Bob Duncan

Portrayed by: Eric Allen Kramer
The 40-something man of the house. Bob runs his own business as an exterminator. He seems rather absent-minded (not being able to recall Gabe's birthday or where he goes to school), and can be quite clumsy at times. He's also quite fond of his daughter Teddy, and can thus be overprotective of her.

Potty John "PJ" Duncan

Portrayed by: Jason Dolley
The 17-year old eldest child of the family. He's a phenomenal airhead and a horrible student. His passion seems to be playing rock and roll, even though he's not very good at it. He cares a good deal about his family and wants earnestly to do his part in helping raise his baby sister, but his absentmindedness makes this difficult.

  • Aloof Big Brother: To Gabe.
  • And Starring: "and Jason Dolley"
  • Character Development: He becomes noticeable smarter and more ambitious as the series goes on.
  • Cloudcuckoolander
  • Cool Big Bro: To Charlie.
  • Dreadful Musician: Depending on the Writer
  • Deadpan Snarker: Has his moments, most notable in Name That Baby.
  • Dumbass Teenage Son: A good example would be his boss putting him on the case to find out whose been stealing chicken from the restaurant. It was the boss himself, and he put PJ on the case because he figured he was too stupid to work it out.
  • Dumb Blonde: PJ is the family Ditz and has blonde hair.
  • Embarrassing First Name: According to his birth certificate, PJ's name is revealed to be "Potty John". Bob tries to get it corrected, but PJ's name is now "PP" Duncan.
  • Expy:
    • PJ is a grungier, working-class version of Newt Livingston. This is made even more pronounced by the fact that the same actor plays both characters. PJ is probably smarter than Newt, but the characters on this show are smarter too, so it balances out.
    • Older viewers might notice a few striking resemblances to Jeff Spicoli. Take away the surfer accent, the Brilliant, but Lazy facets of Spicoli and the fact that Disney can't feature the main trait that everyone remembers Spicoli for, and you have PJ.
  • Follow in My Footsteps: Bob states that he'd like PJ to join him in pest control, and he'd rename the company to "Duncan & Son" if he did. PJ immediately decides to go study.
  • Genius Ditz: It's been stated and proven that he's the best cook in the house.
  • Kiddie Kid: In spades. The most visible example being how his favorite show is The Gurgles, a Teletubbies Expy starring singing, dancing shapes that even Charlie has outgrown.
  • Momma's Boy: Of all the Duncan kids, PJ is undoubtedly the one closest to Amy. Amy in turn acknowledges that he is her favourite. Generally portrayed in a positive and often sweet light.
  • Nice Guy: Bob views PJ as the nicest of his children.
  • Official Couple: With Skyler.
  • Only Known by Their Nickname: PJ is suppose to be short for Patrick John. Due to Bob's poor penmanship on the birth certificate, it actually stands for Potty John.
  • Pretty Boy
  • Smarter Than You Look: Hinted at, as when he's focused, he's surprisingly on the ball. Mrs. Dabney even lampshades it: "Sometimes youre smart, sometimes you're dumb. Hard to keep up."
  • Supreme Chef: He's not the brightest bulb in the box, but he's one heck of a cook (at least in comparison to Amy).
  • Uncanny Family Resemblance: A video of Bob from his high school basketball days shows that he looked exactly like his son PJ does today, only with longer hair.
  • Unfortunate Names: PJ's name was supposed to be Patty John, after his grandfather Patrick John, but Bob was so frazzled when signing the birth certificate, that he wrote "Potty John" instead. This is fixed by the end of the episode though. But now it instead reads "PP".

Toby Wan Kenobi Duncan

Portrayed by: Jake Cinoa & Logan Moreau (not credited in opening titles)
The newest addition, he shares a birthday with Charlie.

Recurring Characters:

Ivy Wentz

Portrayed by: Raven Goodwin
Teddy's best friend. She hopes some of Teddy's popularity will rub off on her, and she thinks the Duncan family is incredibly strange but more entertaining than her own family. She's also a horrible student who rejoices over receiving her first B.


Portrayed by: Micah Williams
PJ's somewhat nerdy best friend, and the drummer in his band. He has an incredibly creepy crush on Teddy, which he's deluded himself into thinking is an actual relationship.

Mrs. Estelle Dabney

Portrayed by: Patricia Belcher
The Duncans' next-door neighbor. Mrs. Dabney is cranky, unfriendly, and at times, manipulative. Born in 1958 in Sheboygan, Wisconsin, she comes from a set of identical quintuplets, none of which are anything like her personality-wise.

Spencer Walsh

Portrayed by: Shane Harper
Teddy's study buddy, love interest, and eventual boyfriend (and then eventual EX-boyfriend). After numerous botched attempts, he finally gives Teddy her first kiss. He comes from a wealthy family, about which he's quite modest, and enjoys hip-hop dancing... oh, yeah, and he's a two-timing jerk. Teddy recently decided to give him a second chance and they're back together.

  • Character Development: Spencer started out looking like a Satellite Love Interest, but later turned out to be pretty interesting. And then turns out to be a cheating Jerkass. To his credit, Spencer deeply regretted his actions, and has made up with Teddy. They're dating once more.
  • Did Not Get the Girl: Sadly, in Teddy's Choice, he does not end up with her, this time through no fault of his own.
  • Dumb Jock: At least from Victor's point of view.
  • Mistaken for Cheating: Subverted. Teddy thinks Spencer is cheating on her with Skyler, but then learns from Spencer that she's his cousin. He turns out to be lying. He is cheating on her with Skyler, who believes that Teddy is his cousin.
  • Mr. Fanservice
  • My Greatest Failure: Cheating on Teddy.
  • Official Couple: With Teddy, as of "Charlie Goes Viral", and up until "Girl Bites Dog". Restarted in "Can You Keep a Secret?"
  • Your Cheating Heart: Turns out Spencer was using the "cousin" excuse to keep Teddy and Skyler from finding out about each other. Doesn't end well for him. For Spencer, this has since become his greatest regret, and it takes a whole season for him to eventually gains Teddy trust while she begins to remember what he meant to her before she fully forgives him enough to take him back.

Jo Keener

Portrayed by: G. Hannelius
A female student in one of Gabe's classes, she constantly threatens and bullies him. It turns out a part of her motivation is being unable to express her crush on him. Not likely to be seen again since the actress has moved onto other projects, namely Dog with a Blog on the same network.
