==Overview==
[[File:RoolDAirLedge.png|thumb|300px|A hitbox visual of King K. Rool's down aerial against the ledge. This allows K. Rool to get easy 2-frames, possibly even KOing characters with a meteor smash.]]
K. Rool does a flip before stomping downwards. Down aerial has a particularly weak meteor smash, but a lingering hitbox lending it some use as a [[sex kick]] of sorts. However the hitbox is quite thin and the move as a whole is a bit slow, often making it difficult for K. Rool players to use. However, the payoff for landing it is immense. 

Down aerial is K. Rool's best grab confirm once forward aerial has started to send into [[tumble]] (which makes grab almost impossible), up until down aerial's early hit sends too high off the ground, usually post-[[tumble]]<ref>https://docs.google.com/spreadsheets/d/1D_yM8UhNDiQXFlyTx-fHM_uFjZ5hN9sffAZ3wYUlrRg/edit?usp=sharing</ref>. Tumble occurs at 50%. This allows for absurd damage in a short space of time, with down aerial dealing 15% alone and K. Rool's grab game allowing for many different routes to deal damage. Usually, a single hit of down aerial can lead to at least 45% in damage. 

Down aerial is capable of [[lock]]ing opponents until it sends into tumble as well, which as mentioned before is around 50%. The sourspot will also lock until around 15%. These allow for K. Rool to get very high damage output from his lock combos, usually ending with [[King K. Rool (SSBU)/Dash attack|dash attack]], or if the player isn't confident, [[King K. Rool (SSBU)/Forward tilt|forward tilt]]. However, hitting opponents as they get up with another down aerial can be used for further combo extension. These are often set up by [[King K. Rool (SSBU)/Neutral attack|neutral attack]] or [[King K. Rool (SSBU)/Forward aerial|forward aerial]], or very rarely low [[percentage]] [[Crownerang]]. While forward tilt can set these up, the hit advantage is almost never enough to justify attempting to do so. 

Down aerial's most powerful utility comes as a hard punish for players not [[mash]]ing fast enough out of [[King K. Rool (SSBU)/Down throw|down throw]] or [[King K. Rool (SSBU)/Down tilt|down tilt]]. This is because it is possible to store its meteor smashes in [[Bury|buried]] states for around 40-50%, allowing K. Rool to get incredible combos. Down tilt virtually guarantees these from around 70%, allowing for [[King K. Rool (SSBU)/Forward smash|forward smash]] or [[grab]] confirms. It's also very helpful as an [[out of shield]] option through [[SHFF]], which is one of the few options King K. Rool has that can be seen as reliable. 

Down aerial's hitbox is very large vertically, extending past the feet, thus making it [[disjoint]]ed. This makes it extremely good for 2-framing, as the hitbox reaches well below the ledge. In fact, due to this, it is possible to nail opponents before it is even possible to 2-frame them, due to how far the hitbox goes below the stage. The high amount of active frames makes this even easier, and if it fails there is usually enough time to get a [[King K. Rool (SSBU)/Neutral aerial|neutral aerial]] ledgetrap off. In a similar vein, down aerial hits below [[platform]]s, allowing it to be used to stave off platform pressure and even combo from around 80%.

Naturally this large hitbox also makes it easy to end stocks with [[meteor smash]]es offstage. However, the FAF is very high, meaning a [[fast fall]] down aerial offstage will lead to an [[SD]]. The meteor smash is also weak, meaning it isn't safe on hit until it actually sends into tumble, although it is recommended to wait until around 80% to start doing it properly. The sourspot is also very good for edgeguarding, sending at an awkward angle (usually around ~38 going by [[sakurai angle]] calculations), and the sweetspot on the hip has 20 more base knockback than the feet, scoring a KO reasonably early. 

However, down aerial has significant drawbacks. The hitbox is extremely thin, making it difficult to use in neutral or even advantage. It is also very unsafe on whiff despite the [[Belly Super Armor]] backing it up, with it essentially being a free grab for the opponent once the hitbox has terminated. The move is also quite laggy on startup (frame 14) ''and'' endlag (with 14 frames of landing lag and a very large FAF), and doesn't [[autocancel]] out of short hop, further worsening this issue. As a result, down aerial is usually used for whiff punishing or bury combo extension.

==Trivia==
*Similarly to King K. Rool's {{mvsub|King K. Rool|SSBU|back aerial}}, the move's scripts have a line for terminating [[intangibility]] on frame 18, but without any line for starting it. This implies it was intended to grant intangibility of some sort (such as on King K. Rool's legs to create disjoint) at some point in development, but ended up being scrapped.
