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.
