Diddy Kong is the sidekick and nephew of Turbo Charge Donkey Kong. He appears in the Nintendo versions of Skylanders: SuperChargers as part of DK's soul gem. He also appears in the Barrel Blaster when Donkey Kong supercharges his vehicle.
When Diddy Kong is summoned through Donkey Kong's Soul Gem, he flys around with a jet pack and fires with his Peanut Popgun.
- He and Donkey Kong are the only characters in the Skylanders series to have five digits rather than four or three.
- He is the first assisting guest character (the second being Aku Aku and the third being Uka Uka).
- It is possible to see two Diddy Kongs when you activate Donkey Kong's soul gem next to where you need to get on the Barrel Blaster.
