Show Summary

Imagine having a lollipop that gives you the strength of a hundred men or a rocket-powered backpack that can send you to the Moon or genetically altering your dog to make him talk. Johnny Test can do all of that... and more! So it's not just another day in the life of a boy. Johnny Test chronicles the adventures of a fearless 11-year-old boy, his genetically engineered super dog Dukey and his 13-year-old super genius scientist twin sisters, Susan and Mary, who use Johnny as their guinea pig for their out-of-this-world scientific experiments. And half of the time their experiments cause something bad or earth-deadly to happen. Then they have to save the day after they started it.

  • Why?! This show is one of the most unbearable!

    Ever since The WB and UPN merged into the The CW and Kids WB was shut down and Cartoon Network picked up the series, this show has been nothing but trouble to this society. And I thought Family Guy was a lot more bad. When I first saw it, I really thought it was good, but now all I see is crap, nothing but horrible, horrible CRAP!!! This show is a rip-off of: Dexter's Laboratory, Scooby-Doo, Fairly Oddparents, Pokemon and so on. I glad it got cancelled, but the one character that I like more was Johnny's mother, she's attractive. Anyways, I'm happy that it's done.moreless
  • CN's version of CatDog

    Admit both this and the other show were lame then and there lame now. And like CatDog the characters are stereotypes, the plots are nothing special and the antagonist would win at the end. If Boomerang reran this, don't waist your time.
  • Ah, Teletoon/Cartoon Network you kept letting this dead horse be beaten.

    This show started very fresh actually, but over time, it just existed, its plots were just rehashed over time, its characters became over used and it just led to the show becoming annoying and not wanted anymore and thus its reputation became crappy and it ended with one.
  • Ugh Johnny Test

    This show is not horrible i have seen way worse its just incredibly bland and really boring there is a big difference between a bad and boring show a horrible show would just offend and disgust me a boring show is just Meh. This show is pretty much a rip off of Dexter's laboratory, Its about a little boy who thinks he is cool, his talking dog Dookie and his genius big sisters. normally Johnny really wants something his sisters make the exact invention they need sisters say no he takes the invention any way or blackmails them and then he misuses it and everything goes horribly wrong and they always save the day. That is almost every episode. If you compare this to better shows like Doraemon and Dexter's lab you will probably like those two better because Dexter's lab was not formulaic and all the characters were vivid Some episodes were about Dee Dee annoying Dexter, Some episodes about Dee Dee Some episodes were about Dexter making an invention and things going horribly wrong some episodes were centered around just mom and dad and some episodes Dexter didn't even use his lab and some episodes were about Mandark . In Dexter's lab you never know what will happen next its incredibly unpredictable most of the time Johnny Test is just the same recycled plots over and over .Doraemon ( its an anime look up the English dub its awesome) is absolutely hilarious A) The plots are unpredictable the characters will obviously screw up but it is always hilarious to watch , B) the gadgets are allays creative, C) The characters aren't bland and one dimensional like n Johnny test D) They don't recycle the same story line (E the characters are lovable and the characters actually have range in there personalities unlike johnny testmoreless

    I hate this show, Johnny is an annoying, ***ed, ugly, stupid, spoiled little *** that needs to die and so as his family. This show is very uncreative and poorly made, the plots are repetitive, and the characters are poorly made and their personalities are undeveloped. This show possibly ended on December 25, 2014 (Christmas). Every other show is better than this shitty show that rips off Dexter's Lab.
