Main characters

Johnny Test

is the titular protagonist of the show, the brother of Susan and Mary and the youngest child of Hugh and Lila. Johnny is 11 years old and best friends with his talking dog, Dukey. He is a mischievous, egotistical, and unpredictable young boy who's often called the "kid with the flaming hair" due to having scarlet red highlights in his blonde hair. Johnny typically wears green cargo pants, a navy blue dress shirt over a black T-shirt with a nuclear symbol, a black watch with a green visor, and black hi-top sneakers. Johnny can live any kid's dream because of his genius sisters, only to find that some aren't worth living. He tends to be showing hyperactivity and laziness quickly. In the course of these escapades, he often messes with his sisters' inventions, causing trouble and mayhem for the town. Just as often, however, Johnny proves himself to be very clever, either by convincing his sisters to help him solve his created problems or by saving the day from whatever good happens to show up. Unfortunately, he always resorts to deceit to get what he wants and he angrily bemoans when things don't work out to his liking. Johnny's catchphrase is "Whoa, didn't see that coming!" during an unexpected event. Despite being generally repulsed by girls, he has nurtured attraction towards his classmates Janet and Sissy, the latter out of hostile rivalry. As a procrastinator, Johnny goes to great lengths to avoid any work, often using his sisters' inventions to do so, putting himself and others in danger as a result. He also has a superhero alter ego that he calls "Johnny X", whose superpowers include hurricane hands, shapeshifting, fire-powered transformation, teleportation, ESP, and "Power poots". A running gag for this form is that his hurricane hands never work, either due to the target being immune to it or other factors.

Dukey

Dukeson Leonard "Dukey" Test is Johnny's anthropomorphic talking pet Leonberger and best friend. He often serves as the voice of reason whenever Johnny is on the verge of making a destructive or hasty decision. The cause of Dukey's anthropomorphism is the result of one of Susan and Mary's inventions. Dukey will usually behave human-like around Johnny, Mary, and Susan, but will revert to acting like a dog around others, including Hugh and Lila. A running gag involves Dukey accidentally speaking in someone's presence, causing them to question "Did that dog just talk?" with Johnny, Mary, or Susan answering "No". On the occasions that Dukey has been seen in public, he dresses up in various clothing and passes himself as Johnny's "hairy friend" or "the kid with the rare hair disorder". His superhero name was "Super Pooch", but then changed to "Super Dukey." Super Dukey has all the same power as Johnny X, but usually crashes while flying. His TinyMon name is "Mymuttdog," and he evolves into "Dukandra." In the 2005 pitch pilot, Dukey was originally named "Poochy".

Susan and Mary Test

Susan and Mary Test are Johnny's genius twin sisters and daughters of Hugh and Lila, who frequently use him as a lab rat for various inventions, most of which to impress their neighbor, Gil. Though they generally refuse to help Johnny in his antics, they usually end up doing so anyway due to Johnny blackmailing or manipulating them, or in exchange for Johnny allowing them to use him as a test subject. Their hard-headed demeanor makes them gullible, and they have been tricked by Johnny on various occasions. They have a habit of speaking in unison especially when reciting their catchphrase "We're such geniuses". Both twins wear traditional lab coats and harbor a deep love and obsession for the Tests' next-door neighbor, Gil, although their attempts to attract his attention always fail. Both girls attend school at the Porkbelly Institution of Technology.
  • Susannah Laura "Susan" Test is the younger twin. A 13-year-old girl who's the sister of Mary and Johnny and the technical middle child of Hugh and Lila. Susan has navy blue eyes, wears black skirt, knee-high socks, a pair of Mary Janes, and a light blue t-shirt depicting a blue star. She has straight red hair, is held with a yellow star-shaped clip, and wears square-shaped glasses. Susan tends to be more irritable and harsh than Mary is, which often leads to her downfall. In the episode "Johnnymon," she claims to lack sympathy for anyone. Eugene/Bling-Bling expresses fond interest in Susan, much to her disinterest. When Bling-Bling pursues Susan, she tries to bribe Johnny into protecting her. Her Catchphrases are "too much?" and "got carried away."
  • Marionette Louise "Mary" Test is the older twin. A 13-year-old girl who's the sister of Susan and Johnny; and the technical oldest child of Hugh and Lila. She has greenish-blue eyes and often wears baggy blue jeans and green sneakers with her trademark yellow t-shirt depicting light blue half moon. Mary has curly red hair, is held with a light moon-shaped clip, and wears moon-shaped glasses. Mary is more friendly and warm-hearted than Susan. She believes less in science and more in science fiction, which somehow always proves to be correct, despite Susan's scorn. She is also more level-headed and conservative than Susan and speaks her mind much less often.

    Secondary characters

Hugh Test

Hubert "Hugh" Test is the stay-at-home father of the Test family and husband to Lila. Throughout the series, he is portrayed as the disciplinarian of the Test household since, unlike his wife, he has shown to be the one who is more likely to scold and punish his children, mostly Johnny. Hugh has blond hair, blue eyes and wears a green sweater over a yellow shirt with brown pants and loafers. Hugh is naive because Dark Vegan can perform a mind trick on him and they only work on dumb people. Hugh's two biggest obsessions are cleaning and cooking meatloaf which the rest of the Test family and anybody else openly despises. He also gets distracted if he loses his shoe and can't focus on anything if he does, something that Johnny occasionally exploits. Hugh often wants his children to come back before dinner at risk of being grounded. A running gag is that he will often ground them for a month for even the smallest offense or for ridiculous reasons, using his annoyed temper. Hugh has forced everyone or trick anyone to get his way such as giving up all her phones due to vacationing reasons. He outlaws genetic experiments by Susan and Mary towards beings ; despite it being frequently defied. Even with his obsession for the rules, Hugh loves his family. He says that he put rules for the family's security.

Lila Test

Lila Test is the mother of Johnny, Susan, and Mary and wife of Hugh. She has brownish-reddish hair, green eyes, and wears a typical women's work suit, pearl necklace, and heels. She is a businesswoman who specializes in telemarketing. Due to the demands of her job and the fact she's a workaholic, Lila isn't seen at home as often as the rest of the family, but her family always comes first and she never misses out on vacations and family events. Lila also possesses martial arts skills, was shown to be strong enough to defeat a towering caveman-themed wrestler, and is shown to be less strict than her husband, but sometimes forced against her will to take a break from work to relax. Lila has a scary/crazy side that even Hugh has shown fear when he makes mistakes in front of her. She is a dedicated perfectionist and will have a mental breakdown when pushed too far.

Gil Nexdor

Gilbert "Gil" Nexdor is a handsome 15-year-old boy and Susan and Mary's crush who doesn't even know they exist, despite having lived next door to him since they were born and even having met them face to face on several occasions. He is continuously depicted as intellectually lacking, although his handsome looks compensate for this most of the time. Much to the great ire of Susan and Mary, Gil considers Johnny his friend. Due to Susan and Mary's crush, many of their experiments often revolve around him, on some occasions even affecting him directly. However, he can never seem to remember their names save for occasions. Gil's surname "Nexdor" is a pun on "next door," alluding to the fact that he is Johnny's next-door neighbor and a play on the term "girl next door", of which stock character Gil serves as a genderbent example of. In the first season, Gil was actually halfway competent and a bit intelligent.

Mr. Black and Mr. White

Mr. Black and Mr. White are two secret agents who ask the Tests for help whenever they cannot handle a crisis alone. They seem to be highly incompetent and somewhat slackers at their job. Ironically, Mr. White is black and Mr. Black is white. Despite first appearing as villains, they're now friends to the Test kids on most occasions. They also have a hidden passion for cooking and dream of a vacation in Fiji.

General

The General is Mr. White and Black's boss and leader of the area 51.1 army base. Loud, slightly incompetent, and forgetful, he frequently takes action whenever the situation becomes too large for the Tests to maintain, although his efforts never fare any better. Even though he doesn't approve of the Test Family and their experiments, he still considers them an ally. The General is prone to overkill and rarely considers what result his actions may have on civilians, to the point he fired at a forest, an inhabited area, and even an amusement park, all in an attempt to destroy a monster. He is also very prone to be a glory hog and gloater when he is successful. The running gags in the series involves the General forgetting something and hesitating to remember and planning to get Johnny, Dukey, Susan and Mary an internship when they graduate. The General also stated in an episode about the test kids “Once you graduate high school, you kids are SO hired!”
