This page is for the character in The Real Adventures of Jonny Quest. For other versions of Jessie, see Jessie (disambiguation).

Jessica "Jessie" Bannon is a member of the Quest team and a friend to Jonny Quest and Hadji Singh. She is the only daughter of Race Bannon and Estella Velasquez; when she's not with the Quest team, she's with her mother, who's an archaeologist.

Physical appearance

Jessie is a teenage girl with green eyes, red hair that goes past her shoulders, and fair skin. She has a slim athletic build.

In season one, Jessie typically wears the color green, with her regular outfit being a green shirt and jeans. In season two, she typically wears pink, with her regular outfit being a pink romper over a light blue/lavender long-sleeved shirt and purple leggings.


Jessie is a year older and little more mature than Jonny. She is slightly more reluctant to go along with Jonny when it involves defying Dr. Quest or her father, but she is more adventurous than Hadji.

In-depth character background

Jessie Bannon is Race Bannon's daughter by Estella Velasquez, and a good friend of Hadji Singh, Jonny Quest, and Dr. Benton Quest. She accompanies the Quest family on many of their adventures, providing another voice of intelligence in addition to Hadji's eastern approach and Jonny's impulsive resourcefulness. She identifies with Dr. Quest more than her father, and is eager to analyze new information and help in the course of Dr. Quest's phenomenology investigations. She's revealed in "Thoughtscape" to be very ambitious at heart, hoping to improve humanity through her dedicated effort and research.


She knows how to code and repair broken computers, drive a quest bike in Questworld, and ride a hoverboard.
