Rocketbarrel Barrage is Diddy Kong's Final Smash. When activated, Diddy will be able to fly freely with his Rocketbarrel Pack and fire extremely powerful shots from his Peanut Popguns. Each peanut does about 28% damage, making contact with the Rocketbarrel itself causes 18% damage, and has more knockback then the peanuts.
When the attack ends, Diddy's Rocketbarrel Pack violently explodes, sending the Rocketbarrels flying in different directions. This does not deal damage. Diddy is flung into the air and becomes helpless. Some peanuts left over from the attack can be consumed for a small amount of health recovery. Sakurai suggested not to fire randomly because opponents can also eat any peanuts that miss and heal themselves, although the peanuts heal very little damage compared to the damage they deal. Take caution to return to the stage when the Final Smash ends, or you can easily SD or be edgehogged while becoming helpless. Fire at opponents hanging from a ledge at a small distance repeatedly, so they can't edge-hog you or abuse the temporary ledge invincibility.
Diddy Kong's Final Smash. Equipping his rocketbarrels and dual peanut popguns, Diddy can fly around attacking opponents in rapid-fire fashion. He can tilt the barrel jets left or right to control his flight and shoot peanuts straight down, too. This is a technique that tests one's ability to control both movement and attack direction.
The Rocketbarrel barrage comes from Donkey Kong 64 as an attack exclusive to Diddy Kong. It is usable by finding a barrel with Diddy's face on and is powered by crystal coconuts. It's main use in various levels and used in minigames is to collect Golden bananas that are unable to be grabbed by other Kongs.
- Rocketbarrel Barrage is one of the only Final Smashes that appears in the Subspace Emissary. Diddy Kong used it on the skiff carrying DK's trophy, clearing the four Primids off.
