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! 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. When it comes to adventures, Johnny and his souped-up super mutt are a team obsessed with pushing the limits - speed limits, time limits, physical limits, you name it. Johnny is the ultimate test pilot where no mission is too insane, no challenge is too great, no villain is too menacing - and no sister-created concoction is too wild. As long as his dog Dukey can come along, Johnny gives it a go!
