Duke is a character in the separate cartoon and comic book continuities of Captain N: The Game Master. The two versions of the character share a lot of personality traits and some backstory.
Duke is Kevin Keene's pet dog from Earth. Oddly enough, when Duke is shown in the live action scene in the first episode/intro, he is shown to be a Golden Retriever, while in the cartoon/comic, he is shown as a beagle.
He's a very loyal canine friend to Kevin. Duke is shown to be protective not only to Kevin, but to his fellow N Team members. However, Duke is not very brave when it comes to some adventures. Sometimes, he can lead Kevin or the N Team into trouble. One true moment of his bravery is shown in "Germ Wars," where he and Gameboy adventured to Faxanadu to retrieve the elixir.
He liked to hold Kevin's grey Zapper (the NES accessory) in his mouth.
- Intelligence: Duke is apparently sentient and can understand English.
- Enhanced Sense of Smell: As every dog, Duke has up to 700 times the smell sense of a human.
Relationships with Other Characters
Duke holding onto Kevin's grey Zapper in his mouth amused Kevin. ("Kevin in Videoland")

Duke and Gameboy seem to have a close bond with each other. In the episode titled "Gameboy," Duke stayed by the computer boy's side when his batteries were removed. Duke and Gameboy both ventured to Faxanadu together.
Despite the fact that Simon seems to loathe him, Duke seems to like to lick the vampire hunter's face at times. Duke sometimes will quarrel with Simon, just to annoy him.
This section requires expansion.
- Duke is the only N Team member to not work for for/fall under the control of a villain at any point in the cartoon.
- Simon was manipulated by the Forces of Chaos twice, and was controlled by hypnotic ink, along with Kid Icarus, Mega Man and Lana. Gameboy was reprogrammed into Game Brain, and Kevin was tricked into working for Astos. Lana was also possessed by the spirit of Konga.
- Duke was also never planned to be controlled by a villain as well. In addition to the aforementioned events, Mother Brain planned to steal Lana's body, and King Hippo and Eggplant Wizard were presumably supposed to hypnotize Gameboy and Kevin in The Invasion of the Paper Pedalers, but never got a chance.
