Diddy Kong originated from Donkey Kong Country. He is Donkey Kong's nephew and sidekick. In that game he tagged alongside him to take back their bananas, and in the sequel, he and his girlfriend Dixie Kong teamed up to save Donkey Kong. in Donkey Kong Country Returns, he allows Donkey Kong to hover by using his own pair of rockets.
In Smash Bros., Diddy Kong is an agile and tricky fighter with some tools up his arsenal. He can recover with his Rocketbarrels, pelt players with peanuts using his Peanut Popgun, and even trip up foes with Banana Peels. Diddy is also much more flexible this time around, having an extended reach for some of his physical attacks.
