It's docious magocious!
— Jonah's catchphrase
Jonah is popular, athletic and he tries to encourage Andi Mack to play outside more with him. He is fun and playful especially when playing frisbee with Andi. Jonah was very supportive when he found out Andi's secret and even confronted his girlfriend for not respecting Andi and Bex. Jonah is very social and friendly, probably because of his positive attitude. Cyrus is surprised multiple times that the "cool" Jonah Beck actually wants to talk to him and be his friend. Jonah has many friends, both boys and girls, which causes Andi to become jealous in You're the One That I Want.
However, despite all the positivity, Jonah is delicate and emotionally vulnerable. This is seen many times as he struggles during his relationship with Amber. It becomes more evident when he suffers a panic attack after realizing that he could be losing Andi. In addition, Jonah seems to be either easily forgetful or he has commitment issues; he tends to change his mind a lot, sometimes breaking promises like how he refused to wear matching jackets with Cyrus, and forgot about Andi's sing-along, among others. He struggles to commit to Andi as her boyfriend, telling her that he doesn't like labels.
He has brown hair and green eyes. He dresses like a typical 14-year old, usually wearing casual shirts and jeans.
Jonah Beck starts training Andi Mack to play frisbee when Bex set them up as part of Andi's surprise birthday present. Jonah asks Andi to join his frisbee team. After practice, it is revealed that Jonah has a high school girlfriend, Amber when she comes to pick him up. In Outside the Box, Jonah tells Andi that he likes her bracelet and Andi makes him one. Unfortunately, Amber manipulates Jonah into giving her the bracelet.
Jonah leads his Space Otters Frisbee team for their first game in Shhh!. Unfortunately, Andi can't play with them because she got detention for sleeping in class. Jonah is impressed that Andi has layers. He tells her all about detention, which only helps scare Andi Mack. After the frisbee game, Jonah leads a cheer for Cyrus for keeping the team refreshed.
In Dancing in the Dark, Jonah finds out about Bex being Andi's mom and thinks it's awesome. He asks Andi to take a selfie with him - Cyrus photobombs them. He goes to Andi's dance party during which he dances with Andi for most of the time. When Amber makes fun of Bex and Andi's situation, Jonah confronts her about it.
Jonah apologizes to Andi and Buffy in It's Not About You for what Amber did during Andi's party and says that Amber is sorry. He also asks Cyrus out on a double-date with him, Amber and Iris. During the date, Jonah stands behind with Cyrus when he realizes that Cyrus is scared of the rides.
in She Said, She Said, Jonah is devastated when Andi tells him that she saw Amber with another boy. Amber uses Jonah's phone to text Andi just to prove that she likes Jonah and therefore conclude that she lied about Amber cheating. Jonah tries to give Amber a benefit of doubt, implying that Andi misread the situation. This gets Andi angry at him for not believing her. He tries to apologize to Andi but she kicks him away.
Jonah breaks up with Amber in Dad Influence and isn't ready to date again because of fear of getting hurt. However, after a talk with Cyrus, he gets the courage to follow his instincts and get back together with Amber.
In Terms of Embarrassment, Jonah meets Andi's dad, Bowie Quinn when he comes to "coach" the Space Otters Frisbee Team. He is impressed by Bowie but Andi feels embarrassed. When Jonah goes to Andi's house to ask her to join the rest in watching the game videos recorded, he finds Andi going through his profile online. Andi gets embarrassed and hides from him. He also sends a text to Cyrus saying "U R Girly" which makes Cyrus insecure. Cyrus enlists Buffy to help him look and act more manly to impress Jonah Beck. Later on, Jonah says that he likes Cyrus' usual look and he meant to say "U R Gnarly" but it got auto-corrected.
Jonah struggles to get Amber a birthday gift in She's Turning Into You. He is too distracted that he even goes past Andi without saying hi to her, causing Buffy and Cyrus to think he's ghosting Andi. When Andi goes to talk to him, he reveals that it's Amber's birthday and he's stressing over the perfect gift to get her. She never seems to like any gift he gives her. So, Andi takes Jonah to The Fringe for gift ideas. Bex asks Jonah to give Amber make up as a gift and then takes the opportunity to give Andi make up in front of Jonah, hoping that he will notice how beautiful she is. Jonah says she's really pretty. Amber loves Jonah's gift but unfortunately doesn't like his card. She gives him a second chance by making him go back and write a more personal message on the card. Jonah asks Andi for help and Andi promises to help him later. He tells her that she's a great pal and that doesn't sit very well with Andi. So, Andi hides from him and rides away with Bex. Jonah is left stressing over what to do with Amber's gift.
In Home Away From Home, Amber and Iris bail on their double date with Jonah and Cyrus. Jonah tells Cyrus that Iris is giving him the silent treatment, revealing that Amber gives him the silent treatment all the time. Cyrus tells Jonah that they should just continue with the date just the two of them without the girls. Jonah takes a lot of pictures with Cyrus while they're having fun together. They even buy matching jackets and plan to wear them together the following day. Cyrus puts on the jacket but Jonah refuses to wear it saying that it makes them look like dorks. Cyrus walks away from Jonah heartbroken.
It's Jefferson Middle School's picture day in Were We Ever? and Jonah is very excited for his Space Otters Frisbee Team to get their first team photo. He finds Andi and other students protesting against the unreasonable dress code and he's clueless what's going on. Andi explains to him that they're wearing prison outfits to protest against the dress code because it's like being in prison. Jonah pays little attention and emphasizes on reminding Andi not to miss the Space Otters team photo. When Andi shows up for the team photo in the prison outfit, Jonah insists that she should change and put on the Space Otters jersey. Andi tells him how important the protest is but Jonah insists on how important Space Otters is for him. So, Andi makes it simple: if Jonah can tell her why she's wearing the prison outfit, then she will change into Space Otters jersey for the photo. Jonah can't remember. Andi walks away.
When the protest causes the school photos to be cancelled, Jonah comes to Andi and apologizes for being preoccupied with Space Otters. He tells Andi that they're doing a retake of the team photo tomorrow and wants Andi to be there. Andi tells him that she doesn't want to take the photo with the team. She doesn't want to be part of the team. She only joined the team because of Jonah Beck. And she does everything Jonah asks her to do just because he's the one asking. She does so many favors for him including getting birthday gifts for his girlfriend, Amber. Enough is enough. Andi needs to stand for herself and go for what she wants and not what Jonah wants. Jonah asks Andi if they could still be friends after she leaves the team but asks him if they were ever friends. Jonah is left confused and sad at the same time.
In Best Surprise Ever, Jonah is still very upset about losing Andi from Space Otters. To make matters worse, Amber's friends make fun of Space Otters complaining that Ultimate Frisbee is not a real sport. Amber fails to defend Jonah. When Andi comes to The Spoon Diner, Jonah says hi to her but she blows him off. When Andi leaves the diner, Jonah follows her out. Amber tells Jonah that he only left because he likes Andi and Andi likes him back. Amber tells Jonah if Andi looks back, it means she likes him but Jonah doesn't want to wait to see. So he leaves. Both Andi and Cyrus look back. Jonah goes to Cyrus to figure out what's going on with Andi and Cyrus wants to help but Andi is not willing to let them like Jonah again. Cyrus tries to cheer him up by telling him about the Space Otters game but Jonah is too upset to even go. So, he asks Cyrus to tell everyone on the team that the game is cancelled.
To end all the stress, Jonah decides to break up with Amber. Amber blames Andi for "manipulating" Jonah into breaking up with her but Jonah says it has nothing to do with Andi and in fact Amber is the manipulative one. Jonah asks Amber to give back Andi's bracelet, the one she took away from him. Amber walks away, threatening Jonah.
After breaking up with Amber, Jonah Beck returns the bracelet to Andi in Hey, Who Wants Pizza?. He also invites The Good Hair Crew to the Space Otters Frisbee Team party. At first, Andi doesn't accept the invitation but Jonah asks her to think about it. Andi is later convinced by Bex to go to the party. During the Space Otters party, Jonah announces a special award to Cyrus Goodman as the MVP of the team for all his support for the team. After the party, Jonah tells Andi about the break up with Amber. He admits that he likes being around Andi. Andi gives him the bracelet back, saying that it belongs to him now.
Later, Jonah finds out that Amber is now working as a waitress at The Spoon Diner and goes to talk to her. Amber opens up to him about her financial and family situation. She tells him that her dad got fired and has been keeping it a secret. They don't have any money and she needs to work in order to help her family. She asks Jonah to keep it a secret. Jonah accepts and hugs Amber to show that he still supports her. Buffy notices and assumes that Jonah might still like Amber. So, she threatens Jonah to never hurt Andi or any of her friends. Jonah walks away, intimidated.
In Chinese New Year, Jonah goes to Bex's apartment to give Andi her phone because she had left it behind in the cafeteria. He finds Andi preparing to go to CeCe's house for Chinese New Year feast. Jonah offers to join Andi for the feast. Andi tries to uninvite him to avoid the awkwardness with CeCe but can't figure out how. Jonah goes to change but comes for the party wearing a white shirt instead of a red one since he doesn't understand anything about the Chinese culture. Ham gives him a red shirt instead.

After mentioning that he wants him and Cyrus to be able to skateboard together, Cyrus gets encouraged to put more effort. Unfortunately, Cyrus lacks control and balance. So, he falls and gets hurt. Jonah calls for an ambulance and goes with Cyrus to the hospital. He also texts Buffy and Andi about the accident. Andi and Buffy confront Jonah for teaching Cyrus how to skateboard because he should know that Cyrus is very clumsy. It's his defining characteristic. They're later relieved to realize that Cyrus only hurt his finger.
Andi is finally ready to hold hands with Jonah in I Wanna Hold Your Wristband but Jonah hasn't initiated the move first. So, Buffy asks her to make the move.

To make matters worse, Jonah trips and falls, hurting his lip. Andi laughs at him, thinking it's funny. Jonah is embarrassed, so he gets mad at Andi but denies that he's mad. Andi texts him but he refuses to respond and later lies that his phone died. Bex tells Andi to ask Jonah for the third time if he's mad at her. But just before asking him, Andi trips and falls. Jonah laughs at her. They're even now. Jonah is cheerful once again.

He has a hard time choosing between Andi's thing and Natalie's video. He chooses Natalie's video.

He tells Andi that wearing a bracelet would make it look like they're boyfriend and girlfriend. He tells Andi that he doesn't like labels. He reveals that he was only calling Amber "girlfriend" because she made him do that. It turns out, Jonah never really thought of Andi as his girlfriend. To him, she was just a friend.

Later on, Jonah helps Cyrus with picking outfits for his upcoming bar mitzvah.
Jonah goes to Cyrus' Bash-Mitzvah! and doesn't say hi to Andi, making Andi think that he's avoiding her. He tells Cyrus that he didn't break up with Andi; he just doesn't like labels.
