Captain N : The Game Master
Aired: 1989-1991
In the show Captain N, DK appears in a few episodes, often enough that I wouldn't consider it a cameo role, but a recurring role. In the show Donkey Kong is the size of King Kong.
One thing I never liked about this cartoon series, is that it was mostly reruns. They only had 34 episodes over the 3 years it was on NBC.
