Dukey is Johnny's dog and the deuteragonist. One of the most notable things about him is that he has the ability to speak. Johnny got him as a birthday gift for his 11th birthday. He's a dog mutated by Susan and Mary. Since then, he became very intelligent. He is also a master at karate, knows somewhat how to speak Chow Now, play video games and gives great advice. When JohnnySusan,Mary and Dukey are near a human that does not know Dukey and he (Dukey) talks, the other person usually says "Did that dog just talk?". In Hugh's case, if Dukey talks in front of him, he says "Did Dukey just talk?".


He is often the voice of reason to Johnny's insanity, but winds up getting manipulated into supporting Johnny's crazy schemes and adventures (usually because of steak or Johnny tempting him into it). Despite his devotion to Johnny, Dukey frequently expresses deep disdain towards Johnny's less intelligent antics, believing their situation as master and pet is reversed. he usually gets more stressful than his master in dangerous situations, and often gets worried whenever there's a rather risky Test for Johnny from his sisters.


Despite his uniquely human abilities, Dukey's still a dog who can't deny his natural dog urges.His dog habits greatly annoy Johnny's sisters, to which Johnny takes deep delight in. Usually once per episode, when trouble arises and there's no alternative, Dukey will say something along the lines of "Here's an idea: RUN!" Dukey has admitted that he's ticklish and can't resist a belly rub from Johnny.

Similar to Johnny's "Johnny X" form, Dukey also has a secret identity which unlike his master he does not particularly enjoy called "Super Pooch", although he is also referred to as "Super Dukey" and "X-Pooch". He also likes to drink hot coffee. His favorite food is steak (He likes all kinds of steak, but his favorite is porterhouse seen when Dukey quizzes Johnny and his cyborg clone to see who's the real Johnny.)

Dukey also appears to be able to know exactly what happened in certain situations. For example, when Johnny attempts to catch a cold from Sissy Blakely in order to skip school but gets sent flying out of the house, Dukey says something along the lines of "Didn't get the cold?" even though he was waiting outside Sissy's house at the time.

Super Pooch/Super Dukey

Dukey goes as Super Pooch/Super Dukey (later episodes) when Johnny goes as Johnny X. Dukey claims that he hates becoming Super Pooch in "The Revenge of Johnny X". When in "SuperPooch" form, Dukey can fly and in the Third Season has shape shifting powers, the ability to sense what others are doing, and the ability to teleport. He has the power to fly as a sidekick (to Johnny) but usually crashes when landing. Also, in "The Destruction of Johnny X" Dukey claims that his Super Pooch costume gives him a mega-wedgie. Dukey isn't as enthusiastic about being a superhero as Johnny is, but he is forced to go along with his schemes on account of reverse psychology, guilt, and offerings of steak.
