Personal life:
Sonny used to dislike her nickname when she was little, but now she thinks it suits her (as she says when she met Chad in "West Coast Story"). In the first episode, when Sonny was called in to be on So Random!, she might have taken the job of the former cast member Mandy, who has been only mentioned once in the first episode. She also plays a guitar (her guitar case was shown in the first episode and behind her during the theme song) and sings. She's usually eccentric, goofy and a bit childish, often admitting to do things that may seem strange to others. Friendly, sweet, and caring towards those around her, she is known as the nice girl of the group and does her best to help other people with their problems and achieve her dreams, earning mixed results. Whenever Sonny lies, her voice rises in pitch (shown in "Battle of the Networks' Stars").
Sonny shares a dressing room with Tawni Hart, who made it clear in the first episode that she didn't like Sonny. However, their relationship improves somewhat with time--they are on/off friends. Sonny was on MacKenzie Falls in "Sonny at the Falls" because she felt like the cast was dissing her when they dismissed her sketch idea. She also happened to have a lot of fan mail which Tawni hid from her. Thinking she had no fans, Sonny invented a fictional fan called Eric and ended up pretending to be her own fake fan. She was also failing math, and was kicked off of one sketch when she was caught cheating.
Even though Sonny and Chad are a bit mean to each other, they seem to have a crush on each other. They share some romantic moments in "Fast Friends", "Sonny With a Chance of Dating", "Promises, Prom-misses", "The Heartbreak Kid", "Battle of the Networks' Stars", and "Sonny So Far", among other episodes.
Sonny dated James Conroy for a short while in "Sonny With a Chance of Dating". In the past, James had dumped Tawni, but developed a crush on Tawni again when he saw her angry. Recognizing him for the jerk he was, Sonny and Tawni both dumped him simultaneously to teach him a lesson. In "Sonny and the Studio Brat", Sonny had to give Dakota from the Children Having a Dream foundation a tour at So Random!. It turned out that Dakota was the studio executive's daughter, so they had to be nice to her or risk their show's cancellation. Furthermore, the Children Having a Dream (CHAD) Foundation was invented by Dakota so she'd have a way to get into the studio and meet Chad, her secret crush. In "Promises, Prom-misses", Sonny missed her prom in Wisconsin, so she wanted a prom at the So Random! studio. She asked Marshall if she could have one, but he said no, so she decided to have a secret prom, but missed it because she had to distract Marshall to keep him away.
Personality:
As a new cast member at So Random!, Sonny wanted to make her first impression a good one, which turned out to be quite a task when Tawni wasn't the amazing role model Sonny had always imagined. Sonny is often prone to use extreme measures to get her desired outcome, like when she pretended to be her own biggest fan, leading to her tricking the entire cast and even dressing like a guy. Despite that, Sonny is a nice, caring and often a little goofy person, if somewhat naive. She's also got a strong moral standing against lying, as she's not too great at it and usually ends up blurting out the truth, no matter how embarrassing.
Publicity:
Sonny was well promoted when she was added to the cast of So Random!. She was in Tween Weekly several times. When Tawni and Sonny wore the same dress, Sharona pointed out that Sonny was shining and Tawni was "partly clunky with an 80% chance of shame". Sharona also said that "Sonny's hair is fab, and Tawni's hair is drab", but she compared a picture of Tawni from a "Bad Hair Day" sketch with Sonny's student ID photo (which had turned out remarkably well). Thus, since Sonny started on So Random!, she became somewhat of a celebrity.
Relationships:
Chad Dylan Cooper:-
Sonny and Chad on their fake date.Sonny has a love/hate relationship with Chad Dylan Cooper. In "Battle of the Networks' Stars", they realize that they have feelings for each other. They started off as enemies when Chad stole her yogurt and then the So Random! cast's parking spot. In Fast Friends, Sonny got angry with Chad because he used her interview to make himself look better and called him a poser and "the most shallow, self-absorbed, conceited jerk-face [she] has ever met" on national TV. After Sonny talked to Chad about it and he refused to help her, she fought fire with fire and caught Chad being a jerk on camera. Impressed, Chad gave Sonny "props" and said they should hang out sometime. Sonny reminded him that the camera was off, and Chad said he knew.
To make James Conroy jealous, Sonny went on a fake date with Chad in "Sonny With a Chance of Dating". When James Conroy texted Sonny saying he wanted her back, Chad seemed oddly disappointed. Later, when James Conroy came over to their table, Sonny fake-kissed Chad (i.e. clapped her hand over his mouth before "kissing him"); Chad, however, said he'd put on his blog that Sonny kissed him for real. In "Promises, Prom-misses", Sonny un-invited Chad to her secret prom, prompting him to come to the prom uninvited. They shared a dance after everyone had left. In "Sonny: So Far," the Season 1 finale, the two presumably confessed their feelings to each other off-camera and backstage, narrowly escaping having their declaration broadcast on TV thanks to Tawni's intervention.
Tawni Hart:-
Tawni and Sonny in "Cheater Girls".Tawni views Sonny as a rival. While Sonny is really trying to be better friends, Tawni is trying to ruin Sonny's self confidence. However, they do sometimes act like friends ("Cheater Girls", "Sonny With a Chance of Dating"). Tawni is jealous that Sonny gets so much of the spotlight since she started on the show. They share a dressing room with each other. In "Sketchy Beginnings", Tawni laid ground rules about the room and told Sonny to keep out of her spotlight. While Tawni was shredding fan mail from the others, Tawni denied Sonny's peace offering, accidentally stabbing her own hand, and Sonny accidentally destroyed Tawni's stuffed animal Puddy Two-Shoes in the paper shredder. In "You've Got Fan Mail", Sonny was upset because she wasn't receiving any fan mail. Tawni kept getting after Sonny about her lack of fan mail, and while Sonny pretended not to care, she soon decided to disguise herself as her own fictional fan, Eric. Tawni got a crush on Eric at first, mostly because Eric was knowledgeable about beauty products, but eventually found out that "Eric" didn't exist and it was only Sonny in a costume. In the end, Sonny found out that Tawni was the one who hid all of her fan mail, because she was jealous of Sonny's popularity. In "Poll'd Apart", when Sharona was mean to Tawni, Sonny tried to make things better, but, like usual, made the situation even worse when she slipped up and revealed that Tawni was so depressed she was wearing a bald cap. Upon hearing this, Sharona twisted what Sonny said and wrote on her gossip blog that Tawni was bald.
Tawni said in "Promises, Prom-misses" that Sonny looked really pretty in her prom dress. This is so far the only compliment Tawni has ever given Sonny.
Zora Lancaster:-
Sonny and Zora don't usually hang out just the two of them, but do hang out in the group. Zora sees Sonny as rather dumb, since Sonny struggled with learning the geometry Zora was trying to teach her.
Grady Mitchell:-
Sonny said to Tween Weekly that Grady was her favorite cast member. Also, Sonny went out with Grady as his fake girlfriend to make Grady's brother stop teasing him about his lack of popularity with girls.
James Conroy:-
James asked Sonny out on a date to the arena, but when Tawni ruined their date to protect Sonny, James sent flowers to Tawni the next day. But when he saw Sonny on a fake date with Chad, thinking it was real, he tried to dump Tawni, only to be dumped by both girls simultaneously.
Selena Gomez:-
When Chad created A Chad Dylan Cooper Story and cast Selena for the role of Sonny, it made Sonny angry. Selena believed Sonny and Chad would date at some point. In the end, though, Sonny seemed to like Selena nontheless ("Aw, she seems nice. I should call her"). This may also be a reference to the fact that the two actresses, Demi and Selena, are friends in real life.
Lucy:-
Lucy and Sonny are best friends, but they had a fight when Sonny lied to Lucy. In the end, Sonny offered a touching apology and their friendship was restored.
Family:-
Sonny's family is practically unknown; only her mother Connie Munroe appeared in "Sketchy Beginnings" and "Cheater Girls". It is unknown if Sonny has any siblings.
Sketches:
Sonny has proven to be a fine addition to the cast of So Random!. She wrote the sketch "One Bad Bee", which was performed in rap form in "Sketchy Beginnings". She also wrote "Loser Force Five" about five pathetic superheroes, but it was rejected by the other cast members. This caused Sonny to start hanging out at the Falls. But when the So Random! cast wanted her back, they decided to do her sketch anyway. Sonny also wrote a sketch making fun of gossip blogger Sharona in "Poll'd Apart". Sonny sometimes takes her sketches seriously, like a dog sketch she did once. At times, she walks around in her characters' costumes (Madge, Teapot, and Baby Waa Waa).
