List of Jannette and Her Voyage in Space characters

The Disney XD animated series Jannette and Her Voyage in Space has a various row of characters created by Xavier Mosley.

This is centered around the adventures of Jannette Jey, an optimistic teenage girl; and her friends she calls her "posse", Luis Inez; and siblings Max and Cam Johnson. They travel the galaxy to discover various alien races and visit planets for their curiosity.

Jannette Ley
Captain Jannette Isabelle Ley (voiced by Cristina Pucelli) is the leader of her group of friends she calls her "posse", as well as captain of the Mark Infinity. One day, she had found the Mark Infinity crashed landed in the meadow fields outside her neighborhood and telling her posse about it, followed by activating it accidentally with them in it. Ever since that day, she and her friends have started traveling the galaxy.

She is reckless and optimistic on what she does, usually when it comes to being leader. She will usually start to listening to music on her mobile phone with wireless headphones wherever, either on Earth, on the Mark Infinity or on a various planets. She is also somewhat of a tomboy, as she is usually clipping her toenails with her teeth or take her shoes off along with her socks and puts them up on the Mark Infinity's control panel. In almost every episode, she'll be seen wearing different clothes.

Mosley chose Pucelli for the role of Jannette after picturing Pucelli's character Luan Loud (a character from Nickelodeon's The Loud House) with Star Butterfly (a character from Disney's other animated series Star vs. the Forces of Evil) and Mabel Pines (a character from Gravity Falls, another Disney series). Some of her character personality traits originate from some fictional characters from other media Mosley had seen; her habit of listening to various songs on her headphones is similar to Star-Lord from the Marvel Cinematic Universe and serving the role as the captain with a cocky attitude like Han Solo from the Star Wars franchise.

In each episode, she is usually seen wearing a different pair of clothes, similar to Mabel Pines from Gravity Falls and Star Butterfly from Star vs. the Forces of Evil.

Luis Inez
Luis Romano Inez (voiced by Josh Keaton) is Jannette's best friend and secretly her love interest until the third season. He is supportive in Jannette's decisions, yet has worry for what happens to her. When traveling with her, he serves as her cadet He once dated his ex-girlfriend Leslie Harper before meeting Jannette.

Max Johnson
Maximilian Benjamin Roberto "Max" Johnson (voiced by Kath Soucie) is the overweight troublemaking best friend of Luis and baby brother to his sister Cam. He usually pranks and teases his sister when he gets the chance and play app games on his phone in his free-time. He is stubborn and carefree, but he has no problem to stick up to his friends and especially sister. He has the job as Jannette's co-pilot when traveling space.

Mosley based his troublemaking personality off Bart Simpson from The Simpsons.

Cam Johnson
Camellia Louise "Cam" Johnson (voiced by Kari Wahlgren) is Max's older sister and Jannette's third member in her posse. She serves as the straight man to the team, only to be ignored by her friends; mostly by her brother. She and Max have a tough relationship and it only consists of fighting and arguing, but no matter what, they stick together despite their constant bickering. On Jannette's travels, she is the team's maintenence inspector.

Cam's character role is reminiscent to Family Guy's Meg Griffin; with being ignored by the people she's with, put into constant slapstick, being the older sister with an overweight brother, and usually picked on.

Wilson
Wilson (voiced by Kevin Michael Richardson) is a Lanate alien species whose apart of Jannette's intergalatic adventures. Back on his home planet; Lanatane, he was an inventor for his people, but after introducing his superweapon to protect his kind, he was exiled due to their peace-centered lives. Jannette and her posses had found him afterwards and Jannette took him in. He now helps the team as their engineer and weapons specialist in creating new weapons and inventions on their adventures.

Mosley reluctantly chose Richardson for the character due to Gravity Falls and Star vs. the Forces of Evil having used him as an additional voice.

William "Bill" Ley (voiced by Billy West) is Jannette's father who, unlike his wife, respects his daughter's choices, especially when he discovers about her adventures off Earth. He is easy-going and the most polite in the family. His relationship with her daughter has him and Jannette bonding over watching science fiction shows.

Mr. & Mrs. Inez
