DK's simian pal is the newest Smash Bros. fighter.
First appearing in the Rare-developed platformer, Donkey Kong Country, thirteen years ago, Diddy Kong has recently appeared in the Donkey Konga series, Diddy Kong Racing DS, and several Mario spin-off games. Though conspicuously absent as even a trophy in Super Smash Bros. Melee, DK's buddy now enters the arena as the latest fighter to be unveiled for Super Smash Bros. Brawl.
The slightly late update on Smash Bros. DOJO notes that Diddy's moves aren't sufficiently captured in static screenshots. It also mentions that Diddy packs some technological devices from Donkey Kong 64: the Rocketbarrel Boost and the Peanut Pop Gun, though these are not yet demonstrated. See Diddy's screens at the Smash Bros. DOJO!! website.
