Pets Dukey (dog and best friend)
First Appearance Pilot Episode: “Johnny Test” (October 16, 2004)
Voiced by James Arnold Taylor
“Whoa, didn't see that coming...”
— Johnny's main catchphrase

Jonathan Xavier "Johnny" Test is the main protagonist of the series of the same name. He is a mischievous boy known for his love of anything he considers awesome. He is the youngest child and only son of Hugh and Lila and brother of Susan and Mary. He can live any kid's dream, only to find that some dreams aren't worth living. He is typically with his best friend (sometimes partner-in-crime) Dukey, his genetically altered dog. He also redeems coupons to his sisters in exchange for assisting them in their daily problems. Their experiments tend to cause a lot of problems for Porkbelly.


Johnny resembles his father, Hugh. He has blonde hair with reddish-orange ends and blue eyes. Due to his hair dye, he has often been called "the kid with the flaming/'fiery' hair" on several occasions.

Johnny's general clothing consists of a black t-shirt with a yellow hazard/radioactive symbol in the center, a short-sleeved federal blue open jacket, green-baggy pants, and black shoes with white trim and soles. He also wears a black watch on his right wrist. Johnny has also worn different costumes and clothing during the misadventures he goes through because of his sisters' experiments. In Princess Johnny, he wears a white tank top and red boxer shorts with yellow polka dots.


Johnny loves having fun and playing as any child likes, sometimes he can be irresponsible, as well as his refusal to work hard or to put effort into anything when he could just as gets the girls to help him but he usually learns his lessons when he fixes the problem himself. (101 Johnnies, rated J for Johnny, Johnny's Rat Race, etc.) Johnny uses the agency to get his way, though he does love his sisters in a way only a brother can, often trying to save them from whatever trouble they're into he usually saves Porkbelly (despite causes some of the problems in the first place) from the dangerous things that can harm it (using the girls' inventions or turning to Johnny X) as he immediately decides to save the town when a villain is attacking. On the other hand, Johnny can be brave, helpful to others, and even kind and gentle sometimes that usually most of the other characters get surprised because of it. He even proved himself and his skills very well when his teacher said that he can do it. (Johnny Bench) and it appears that he can handle some jobs well if he just put some effort into it.


Hugh Test

Johnny and Hugh have a complicated father-son relationship. As much as Johnny annoys his dad as any other kid would, he sometimes respect his dad, saving him (Johnny's key to success) or trying to help him (Johnny on the job, Johnny's House of Horrors). Although, it seems that they both knew each other lives better after when they switched their lives for one day (Papa Johnny).


Lila usually goes with Johnny's side (My Dinner With Johnny, Johnny's lockdown) and tries to control Hugh and Johnny's weird actions. Although she's often busy with her work and annoyed by Johnny, she still loves her son.

Susan and Mary

Johnny maintains a love-hate relationship with his sisters. They use him as a guinea pig to test their potentially dangerous experiments, usually showing little concern for his health. In return, he often steals their inventions and uses them for his own good. He never listens to his sisters' warnings, which oftentimes leads to problems in Porkbelly. On several occasions, Johnny is shown to agree with his sisters and take their sides or usually save them in case they're in trouble.


Dukey is Johnny's best friend and pet dog since Johnny "saved" him from the puppy pound (Johnny's 100th episode). They both tag along with Johnny's sisters to do their experiments. Dukey acts like Johnny's conscience, trying to keep the young boy out of trouble, but in the end usually goes along with Johnny's idea, often under the promise of steak. although they both go into much trouble, he still respects his pet and often does anything to make him happy (Bath time for Johnny, The Johnnyminster Dog show).

Love Interests


Johnny kissed by Sissy

Sissy and Johnny have been known to have a crush on each other though neither will show it openly. They often compete against each other.

Claire Nefarius

Claire Nefarius

Johnny was attracted to her calling her hot several times. Claire initially didn't like him and was thrown out by her bodyguards several times, which irritated him to no end. He even considered her the villain (which was correct) instead of her father. However, he had made her laugh after using Mr. Black and Mr. White's argument and she invited him to her party.

At the party, his rant about her being evil was true as her father always had to work so she decided to blow up her dad's factory so he can spend time with her.

Soon, when it appeared that their house is nearby the factory, Johnny helped her to stop the missiles and save them. Her personality noticeably improved once she made up with her father, becoming considerably friendlier. She even kissed Johnny on the cheek and wanted to date him but her father stopped this, to Johnny's annoyance. The two have not seen each other since.

Joni West

Johnny and Joni

Johnny and Joni meet in Joni's dimension in the only episode Johnny Alternative and the two had an immediate crush on each other. Johnny helped Joni defeat Madame Mittens and the two almost kissed but Johnny and Dukey were pulled back to their own dimension, the two have not seen each other since.
