Swats in the air above him with a slap and looks similar to an uppercut. Quick and can combine with other attacks. This can be used to juggle at low damage percentages and KO at very high percentages with higher knockback than his up smash.
Spins, slapping forward twice. The first hit has no knockback, comboing into the second hit; however this can be escaped rather easily. The second hit does an extra 3 damage if shielded. When fully charged and both hits connect, it can KO at 94%.
Kicks both feet forward. Diddy's strongest aerial, a great edgeguarding option, and a good move to use in a short hop (though a bair is quicker and better for spacing). On the edge at above 100%, edge drop -> jump -> fair is considered one of the best options available.
Sticks leg out and spins it behind him. His fastest aerial, a great option for spacing whether a short hop is used or not. A short hopped bair is useful for quickly picking up bananas; while an air dodge is usually a better option due to having no landing lag, a bair can knock nearby opponents away.
Throws opponent up and kicks them. Can be comboed with Rocketbarrel Boost, is a decent option for getting opponents into the air. If animation is interrupted by something like a projectile, Diddy Kong will freeze in place.
A sideways hop, which grabs opponents and can be kicked out of. Can be used to gain some extra recovery distance. If Diddy jumps off the opponent in the air, they will be meteor smashed weakly. If the special move button is pressed after the flip, Diddy will kick, being a great combo move that can lead into a fair if a midair jump is available. However, if the kick is used, Rocketbarrel Boost cannot be used until landing. An impractical sacrificial KO is possible with this move by using it in the air and falling to the lower blast line with the opponent (referred to as "Diddycide"). In the Subspace Emissary, does repeated damage to enemies it passes through instead of grabbing.
Diddy charges up his barrels and launches himself upwards. Can be angled with the Control Stick (but not if the move is uncharged). Diddy's primary recovery move, but leaves him vulnerable during the charging and can also self-stage spike on stages such as Final Destination. If Diddy is attacked out of the move, the barrels will fly around and can damage opponents (they also cannot be blocked). Ramming into opponents with the move sends them on a semi-spike trajectory.
