Jonah Wizard is one of the Cahills in the hunt for The 39 Clues. He is an international pop-star and his mother, Cora Wizard (a famous artist), is the leader of the Janus Branch. His father, Broderick Wizard, is his guide and ally throughout the Hunt, and together they form Team Six.
Jonah Wizard is known for his international pop-stardom and his TV show, Who Wants to be a Gangsta? He also has many side projects such as spinning lollipops shaped like himself that spin and say famous "Jonah phrases," and his French picture book, Little Gangster Pop-up Book. His mother, Cora Wizard, is the head of the Janus branch. His father, Broderick Wizard, is Jonah's manager for his singing career. Jonah is always trying to please his mother, but he never can, which is why he is searching for the 39 Clues. By the end of the series he's confused about what he really wants and were his loyalties really lie. He had always been taught to hunt for the Clues, no matter what, but his recent activity with Dan Cahill left him wondering about his family, the Clues, and himself. He was the first person other than the Madrigals to suggest the branches unite.

Appearance and PersonalityJonah is a little conceited, and acts like he's a "gangsta" even though he's from Beverly Hills. He often throws around words that make him sound more "gangsta" such as "yo" and "wassup." He is obsessed with being the best, driven by his mother, Cora Wizard. Though incredibly famous, he always wants more. Jonah is constantly spending money, and can be very extravagant. He also would love to have a friend his own age, and befriended Dan Cahill for a bit in The Emperor's Code. After the Cahills vs. Vespers series begins, he is aligned with the Cahills to rescue the hostages, especially his cousin, Phoenix Wizard. His father is his manager and is always with Jonah, wherever he goes. Broderick also loves to brag about his son, as in The Maze of Bones, when he tells Amy and Dan that his new album is number two on the French charts. Jonah is described as having a dazzling smile,eyes that are almost just like Jane Cahill's, and in The Maze of Bones, is shown to speak fluent French. In the Maze of Bones, he first appears at Grace's funeral wearing ripped jeans and a black muscle shirt, which Dan thought was stupid, since he didn't have much muscle.

When asked about the whereabouts of the Tavernier Blue, he says, "You don't know? It belonged to Louis XV but he was robbed! During the Revolution, those Ekaterina punks...I mean, some thieves, stole the French Crown Jewels. It disappeared for years and then showed up in England. By then it was cut down and known as the Hope Diamond. Yeah, it's in Washington, D.C. Cool town. My shows are always sold out."Dan and Amy in the Nile saying he's always wanted to be a pirate with his dad in the background. Dan from the factory and takes him in when he had no other contact in China after storming away from Amy. He brings Dan to their hotel and treats him exceptionally well, even bringing him to one of his concerts in China. He and Dan forms a sort of alliance when he and his father promises Dan to try and contact Amy and Nellie, even though he was tricking him and Amy as well when she and Nellie came to his concert, missing Dan by 15 seconds, and answered that he hadn't heard from Dan and promised to tell her if he finds anything as well. They go to the Great Wall of China to find the next clue and where the other Janus members are. He is told about a lead to a clue and discussed using Dan as decoy, if it was a trap.

She tries to trick Dan into helping them by telling them all that Dan belonged to the Janus Branch, but, knowing his real branch, Dan slips out that he is a Madrigal and gains satisfaction by seeing their shocked faces. Later on, it shows the Wizard Family talking about what he said. Jonah suggests that Dan was only kidding, but Cora believes that Dan is telling the truth and is furious and disgusted by his previous idea of leaving the clue hunt, even though Jonah did it to escape becoming a power-hungry Janus like his mother.
