Nintendo DS Wiki:Diddy Kong

Diddy Kong is a young Kong who serves as both the sidekick and best friend of Donkey Kong. Diddy was created by Rare, and first appears in the Donkey Kong title Donkey Kong Country. Since his debut, Diddy has become one of the main characters within the Donkey Kong franchise, and even received his own spinoff title, Diddy Kong Racing, later remade for the Nintendo DS as Diddy Kong Racing DS. Like Donkey Kong, Diddy has also appeared in several Mario spinoff titles, usually as a playable character.

The first Nintendo DS game that Diddy appears in is Yakuman DS. Diddy's next appearance for the Nintendo DS, as well as his first appearance on the system outside of Japan, is in Mario Hoops 3-on-3, which features Diddy as an unlockable playable character. Mario Party DS is the last Nintendo DS game in which Diddy appears.

For the backward-compatible Game Boy Advance software, Diddy appears in a few Donkey Kong titles, and his first appearance on the system is in a remake of his overall debut title, Donkey Kong Country. Unlike the Nintendo DS, Diddy does not appear in any Mario titles for the Game Boy Advance.
