==Overview==
A belly flop, emphasising K. Rool's huge weight and armor. King K. Rool's down smash is among his most notorious attacks, thanks to its [[Belly Super Armor]] and [[hurtbox]] shift specifically making [[grab]]s miss. This is because K. Rool's hurtbox moves above conventional grab hitboxes as soon as frame 4. While it deals less knockback than his [[../Forward smash|forward smash]], it remains a monumentally powerful attack, ending stocks as early as 90%. Because of this blend of defense and power, K. Rool's down smash is largely considered to be one of the best [[down smash]]es in the game. 

It is one of the most difficult moves to challenge on startup in the game, due to the aforementioned hurtbox shift and Belly Super Armor. Low attacks and regular grabs simply miss, and regular or high-reaching attacks tend to hit the armor. The only feasible way to challenge the move is to attack from above, where K. Rool completely lacks any armor. This protection, combined with kill power, makes this move a very strong hard punish tool in disadvantage, catching many players overextending with their burst options. It is not uncommon for K. Rool players to watch for greedy dash grabs and use the information to punish poor approaches later, simply because the reward for doing so will be substantially higher compared to other characters.

It is also notable to mention that down smash deals significant [[shield damage]], to the extent that use after a [[../Neutral aerial|neutral aerial]] on a shield is a guaranteed shield break. This notably avoids grabs because of the additional safety of neutral aerial, making a [[perfect shield]] or a roll backwards the only way to avoid it, which in high-pressure situations may not be thought about. However, with repeated use, it becomes better to prepare for these options instead, due to the punishable nature of the move against an experienced player.

Unlike many of K. Rool's attacks being designed to be difficult to challenge but easy to punish, his down smash is reasonably well-defended even after the initial slam is over. It has a surprisingly large "quake" hitbox just outside of the body slam's range, much like his [[../Down tilt|down tilt]]'s. This quake gives a sizable frame advantage on hit, but generally not enough for solid followups outside of his [[../Forward tilt|forward tilt]]. However, if shielded, this quake hitbox has little [[shieldstun]], leaving K. Rool dangerously open regardless; the quake is -34 on shield, enough for even charged smash attacks to be valid punishes. 

The move is typically not used outside of reads and hard punishes, largely because it is quite slow, with Belly Super Armor not switching on until frame 11, and the hitbox coming out frame 22. It has an enormous [[FAF]] of 64, though this is the middle ground in terms of K. Rool's smash attack FAFs. On top of this, in situations where the move can be done for free early stocks — such as shield breaks or if highly punishable moves are used — K. Rool's forward smash angled upwards KOs much earlier, making it strictly suboptimal. Furthermore, if Belly Super Armor is damaged, K. Rool becomes very vulnerable to it breaking: it has 14 active armor frames in total, which is enough for at least some heavy-hitting attacks to hit it, especially considering how the move is used. As a result, many [[Shield break|armor break]]s occur from down smash misuse. All things considered, in higher level play, K. Rool's down smash tends to be used far less on average. 

Contrary to popular belief, while K. Rool leaves the ground as soon as frame 4, he maintains a foot hurtbox extension until frame 7, which makes it deceptively easy to grab him from behind. It is even possible—in fact easier—to grab K. Rool out of his down smash when he has actually began the belly flop. This is commonly seen with [[tether grab]]s such as {{SSBU|Samus}}'s, or large [[pivot grab]]s such as {{SSBU|Greninja}}'s. Naturally, and also humorously, [[command grab]]s such as K. Rool's [[Blunderbuss]] Vacuum can also force him out of it.
