BackgroundBrad made his debut appearance in the pilot episode "It Came From Next Door". He is first seen reading a magazine outside in a lawn chair. He also drives a white 1995 crown victory p71.
Brad is a human adolescent male with apricot-colored skin, spikey orange hair, and dark-colored eyes. He usually wears a white dress shirt with a black vest over it, khaki pants, and black dress shoes.
Brad is known to be very adventurous, and enjoys tagging along when Jenny fights crime. He is also known to be a ladies' man and he tries to get other girls to like him; however, many of the girls he tries to flirt with reject him. Brad dislikes being on the sidelines. Brad is also observed on many occasions as being stubborn. In Unlicensed Flying Object, Brad portrays his more stubborn side of his personality by disregarding his safety having been told not to interfere with anything dangerous. He also has been observed as being slow or unperceptive, which sometimes annoys Jenny.
Brad and Jenny met in the pilot It Came From Next Door. Brad and Jenny have a close friendship and spend a lot of time hanging out together, as well as occasionally teaming up to fight off villains.
Neither of the two display any romantic feelings for each other. However, in the episode Ball and Chain, when Brad was about to marry Space Bikers member Tammy, Jenny broke into the wedding chapel to rescue him. When Brad told Jenny that he actually wanted to marry Tammy and become a Space Biker, Jenny humbly respected his wishes, but told him sadly that she would miss him, wished him luck, and then gave him a small goodbye kiss on the cheek before walking out. Despite this display of friendly affection, their relationship throughout the series has remained strictly platonic.
In a Q&A with Rob Renzetti, he clarified that he had no long-term plans for Jenny's love life, which he considered a minor part of the show anyway.  However, he did admit in an earlier interview that he and his team were rooting for Sheldon (not Brad) in regards to Jenny’s potential love interest. 
Tuck is Brad's younger brother. Since they both have different personalities, they occasionally argue, and display typical sibling rivalry. Despite all this though, they do share a mutual brotherly love for each other. Even when Tuck is annoying most of the time, Brad cares about his younger brother very much, and tries his best to keep him safe from danger.
Dr. Wakeman and Brad don't talk to each other often, but in times when Jenny needs help, are often working together (typically along with Tuck and Sheldon). Dr. Wakeman must constantly interrupt Jenny and Brad when the friends are spending time together because Jenny has duties to protect Tremorton from danger.
Sheldon and Brad are good friends. They often talk to each other in school, spend time together usually when Jenny is around, and go on crazy, wild, and occasionally dangerous adventures with her. Brad is kind to Sheldon and gives advice to him when he is in doubt.
Melody was one of Brad's genuine love interests. Even though she is the robot daughter of an evil mad scientist, Dr. Locus, Brad still falls for her, seeing as she appeared as a pretty and perfect normal girl in her exo-skin. In Bradventure Melody helps Brad safely escape her father's lab with an injured Jenny. When Melody visits him again in No Harmony with Melody Brad decides to take Melody around his town as a date. Melody was the first girl in the series to be seen kissing Brad. Jenny, convinced that Melody was evil like her father, and up to no good with intentions to harm Brad, provokes Melody, causing her explode with rage and reveal her true hideous and monstrous robotic form. Realizing that everyone thought she was a monster, including Brad, Melody gives up, feeling that she will never belong. She flies away in tears, never to return. Brad was still quite sad about Melody's true identity in the end, as he had enjoyed being with her; but he eventually moves on, knowing they were not meant to be together.
Brad is always willing to help keep Jenny safe from and help fight against The Cluster's attacks, and dislikes them as Jenny does.
Brad dislikes Queen Vexus as Jenny does, and is afraid of her as well. However, when she was in disguise at Tremorton High as "Vicky" in Queen Bee, Brad seemed to be a huge fan of her.
Brit and Tiff are popular rich girls who only go for the popular guys; hence, they do not like Brad. Especially since they hate Jenny more than anyone, that makes them dislike Brad even more, seeing as Brad is Jenny's best friend.
The Space Bikers
When they first appeared in The Return of Raggedy Android Brad disliked the Space Bikers, seeing as they attacked all of his friends when they crashed Mezmer's, and gave him an atomic wedgie. Tammy in particular seemed to target him, bully him, and rough him up while seemingly flirting with him. This eventually lead to his biggest problem with the Space Bikers, which occurred in, Ball and Chain where Brad is forced by the Space Bikers to marry Tammy. At first, Brad was very much opposed to this forced wedding and tried to get out of it, but changed his mind when he considered the life of a Space Biker to be exciting, while also developing a crush on Tammy. In the end, when he was told that he would be Tammy’s slave once married to her, Brad tried to break off the wedding, and is nearly eaten by Tammy (one of the traditions on the planet of the Space Bikers if the groom wants to end the marriage — the wife eats him). Thankfully, he is saved by Jenny just in time, and does not have any more encounters with the Space Bikers.
- In the pilot episode, Brad was voiced by a woman, Melissa Denton. But when the show was picked up, she was replaced by Chad Doreck.
- He takes 40 minutes to keep his hair neat and spikey.
- Brad spoke the first line of the series (to his brother Tuck): "Slow down there, slugger. You seem to be light one baseball."
- In the episode Around the World in Eighty Pieces it is revealed that Brad wears size 9 shoes.
