## Spoilers
### Plot
In the suburb of Porkbelly, Johnny Test (James Arnold Taylor) wants something: a gadget, a superpower, or a favor that will impress his neighbor Gil. His twin sisters Susan and Mary Test (Maryke Hendrikse), 13-year-old geniuses who share a lab above the family garage, agree to help only if Johnny agrees to be experimented on. The experiment misfires in a way that threatens Porkbelly, and Johnny fixes the mess with Dukey (Trevor Devall), the family dog the sisters gave human-level intelligence and a taste for coffee and meatloaf. The reboot keeps the original's flourishes, including the whip-crack sound effect that punctuates Johnny's entrances and the sisters' running gag of fighting over the handsome, completely oblivious Gil.
Season 1 runs the greatest hits. Johnny borrows the sisters' tech to become Johnny X, a superhero with a flying board and powers that change from episode to episode, from super speed to a gale-force sneeze. Recurring villains return from the old series: Bling-Bling Boy, the wealthy, gold-plated Eugene who threatens Porkbelly with monsters whenever Susan refuses to love him; Brain Freezer, a frozen-coffee-drinking villain with a freeze ray; and the bumbling secret agents Mr. Black and Mr. White, who recruit Johnny when a threat outgrows the household. Other episodes send Johnny through the sisters' shrink ray, into video games he must beat from the inside, and into competitions against his stuck-up rival Bumper the Bully, whom he beats more often by luck and chaos than by skill.
**A recurring highlight for fans of the franchise is the Johnny X transformation, in which Johnny grabs the sisters' tech, the whip crack snaps, and the show cuts to a full hero sequence with a new costume, a flying board, and a freshly announced power that has never been tested.** The reboot stages it with smoother, brighter animation than the 2005 version and keeps the sisters' deadpan commentary running underneath, Susan and Mary arguing about whose idea the gadget was even as their brother careens toward catastrophe. The joke of the transformation is that it never helps as designed: the power is either absurd, like a burping sonic blast, or it stops working at the worst possible moment, leaving Dukey to talk Johnny through improvising a fix while the villain monologues.
Season 2, which arrived on Netflix on January 7, 2022, keeps the lab-experiment premise and adds new variations: machines that swap bodies, age people backward, and turn household pets into monsters, plus another Bling-Bling Boy scheme to win Susan. The season closes out the run, with TheTVDB marking the series as ended after its January 2022 episodes.[11](https://www.thetvdb.com/series/johnny-test-2021)
### Characters
**Johnny Test** (James Arnold Taylor) is an 11-year-old daredevil with a red-and-yellow mohawk, an extreme-sports streak, and no fear of consequences, which is precisely why his sisters find him useful as a test subject. He is lazy about school and heroic by accident, but he never abandons Dukey or his sisters when things go wrong.
**Susan and Mary Test** (Maryke Hendrikse) are 13-year-old super-scientists who build impossible gadgets in their garage lab and use their brother as a guinea pig. Their one weakness is Gil, the dim but sweet neighbor they both compete to impress.
**Dukey** (Trevor Devall) is the talking, coffee-drinking family dog, the voice of reason who would rather stay home but always gets dragged into the experiment. He disguises himself in pants as "the kid's dog who can talk" only when no adults are watching.
**Bling-Bling Boy** is Eugene, a rich, gold-suited villain whose every monster attack is really a clumsy attempt to make Susan Test love him.
**Hugh and Lila Test**, Johnny's parents, are the oblivious adults: Hugh is obsessed with meatloaf and cleanliness, Lila with her business career, and neither ever quite catches on to what happens upstairs in the lab.
## Production and release
Netflix announced in 2020 that it would be the new home for *Johnny Test*, ordering two new seasons plus an interactive special. The revival carries a refreshed, higher-resolution look and was made available in 4K. Scott Fellows, who created and ran the original series, returned as showrunner, with [WildBrain](https://www.edgepedia.org/wildbrain) (formerly DHX Media) producing.[4](https://www.whats-on-netflix.com/news/johnny-test-reboot-coming-to-netflix-in-july-2021/) WildBrain's investor communications confirmed the studio was in production on two new original seasons exclusively for Netflix.[8](https://investors.wildbrain.com/image/Q4-Full-Year-F2020-Call-Transcript.pdf)
The first-look trailer was released on June 18, 2021, and the entire first season arrived on July 16, 2021. Storywise, the new series picks up where the original left off rather than restarting the premise.[4](https://www.whats-on-netflix.com/news/johnny-test-reboot-coming-to-netflix-in-july-2021/) • [3](https://www.tvtango.com/series/johnny_test_2021) The second season followed on January 7, 2022, opening with "Johnny's Got a Brand New Mom," in which Johnny asks his sisters to build a robot mom to trick his teacher.[3](https://www.tvtango.com/series/johnny_test_2021)
## Format and stories
Unlike the original series, which used two roughly 11-minute segments per half hour, each quarter-hour episode of the revival features a single story. The series opener, "Johnny's Battle Royale," has Bling Bling transport Johnny and the rest of the crew to a real island to show off his combat skills after tiring of losing the game "Melee Island."[3](https://www.tvtango.com/series/johnny_test_2021) Season 2 ranges from VR-wizarding to real-world monster-slaying.[3](https://www.tvtango.com/series/johnny_test_2021)
## Cast
James Arnold Taylor returns as Johnny Test, with Trevor Devall voicing Dukey and Henry Teacherman, Maryke Hendrikse as Susan Test, Emily Tennant as Mary Test, Ian James Corlett as Hugh Test, Kathleen Barr as Lila Test, and Bill Mondy as Mr. Black and Brain Freezer.[3](https://www.tvtango.com/series/johnny_test_2021) Common Sense Media noted that the returning voices of Taylor and Devall keep the show familiar for fans of the original, even though the animation is smoother and some familiar sound effects are gone.[2](https://www.commonsensemedia.org/tv-reviews/johnny-test-2021)
## Reception
Critical coverage was limited. Rotten Tomatoes recorded a 57% Tomatometer from one review; Melissa Camacho of Common Sense Media rated the season 3/5, calling it a fun and imaginative reboot that stays true to the original.[9](https://www.rottentomatoes.com/tv/johnny_test_2021/s01) Common Sense Media recommends the show for ages 7 and up, citing fantasy violence, mild language such as "darn" and "crud," and bathroom humor, while noting science, invention, and family as central themes.[2](https://www.commonsensemedia.org/tv-reviews/johnny-test-2021) On IMDb the revival holds a 6.1/10 rating weighted from about 710 user votes.[7](https://www.imdb.com/title/tt15061770/ratings/)
The series ran for two seasons on Netflix and is listed as ended, with the final episode, "Johnny's Melee Mayhem," airing January 7, 2022.[10](https://www.tvmaze.com/shows/56399/johnny-test)
