Donkey Kong, also known as DK, is a powerful hero Kong from Donkey Kong Island. He is a carefree simian who spends his days collecting Bananas and spending time with his friends, particularly his buddy Diddy Kong. However, when trouble arises, Donkey Kong jumps headfirst into the action to help his friends and protect his island. Donkey Kong's character design was created by Shigeru Miyamoto for the Donkey Kong arcade game.
Donkey Kong and Diddy Kong were enjoying the feast of the Mushroom Kingdom's Anniversary, when they come out (after some time Mario and the others get sucked in) and they notice the Portal. They go towards it by curiosity and get sucked in. They later meet with the Heroes.
