|interwikipage=Barrel Jet

Diddy Kong activates a Rocketbarrel Pack and starts charging it, slowing his fall. When the special attack button is released, he propels himself in the chosen direction.

Touching an opponent while ascending will cause fire [[damage]]. In ''Brawl'', the explosion generated from liftoff also has a hitbox which meteor smashes opponents. If Diddy is attacked while using the move, the barrels will fly off and become irregularly-moving, [[unblockable]] but [[reflect]]able [[projectile]]s, exploding on contact with the stage. The player can alter the direction the barrels will move in for a small amount of time before they lose control. If Diddy hits a surface while using the move, he takes about 5% damage.

From ''[[Super Smash Bros. 4]]'' onward, the move can be used to travel at more horizontal trajectories, improving the move's uses for recovery.

===Barrel jumping===

Barrel jumping is an [[advanced technique]] in ''Brawl'' and ''SSB4''. It is very similar to {{SSBB|Lucas}}'s [[zap jump]] except that the zap jump can be used as an extended jump but the timings are almost exact. When taking knockback, if the player performs a midair jump and quickly executes Rocketbarrel Boost at the same time, then the player moves upwards while charging the move. This results from a mechanic in which if Diddy Kong has any residual knockback when attempting to use the move, it will not disrupt Diddy Kong's momentum like it usually does, including momentum from a jump, and this is amplified by Diddy Kong's gravity being reduced while charging the move, causing his jump to be floaty.

|desc=An item that looks like regular barrels but becomes a rocket-powered jet pack when Diddy Kong straps them on his back. It's a convenient gadget to have when adventuring, but for whatever reason, Diddy also uses it when playing tennis and basketball. The moves he can pull off with the rocketbarrel pack are so cool that they're almost not fair. Almost.

Diddy Kong SSBU Skill Preview Up Special.png|Rocketbarrel Boost as shown by the [[Move List]] in ''Ultimate''.

*In ''Brawl'', charging the move in the air while in lower gravity causes him to float up, as if the gravity was reversed.

*Professional ''Smash 4'' player {{Sm|MVD}} has earned the title "The Barrel Technician", due to his creative use of Rocketbarrel Boost in tournaments, most notably [[CEO 2015]].

*In the Japanese versions of ''Brawl'', the Rocketbarrel Pack's other game appearance is labeled ''Mario Power Tennis'' rather than ''Donkey Kong: Barrel Blast/Jet Race''.
