Johnny Test follows an 11-year-old boy whose genius twin sisters, Susan and Mary, constantly use him as the test subject for their latest inventions. Their experiments give Johnny access to superpowers, robots, time machines and all kinds of strange technology, usually sending him and his talking dog Dukey into increasingly ridiculous situations.

What starts as a simple experiment often spirals into scientific chaos, leaving Johnny to deal with the consequences and somehow put things right.

Kevin’s score keeps pace with the show, shifting between electronic sounds, action scoring and music that plays directly into its humor.
