This is perhaps the best-known Kirbycide. It has been nicknamed '''Swallowcide''' and has been around since the original ''[[Super Smash Bros.]]'' To execute this move, Kirby has to trap an opponent in his mouth using his [[neutral special move]], [[Inhale (Kirby)|Inhale]], and walk off the side of the stage. What makes this form of Kirbycide so effective is that the amount of time required to break out of the Swallow is not affected by the opponent's damage, so it can be performed as low as 0%. Additionally, once Kirby is plummeting off the stage, any opponent who breaks free will drop downward while Kirby stays overhead with all jumps.  Also, Kirby never SD's before his opponent off-screen allowing him a fraction of a second to jump and thereby recover back to the stage. [[King Dedede]] can use his version of {{b|Inhale|King Dedede}} to use this version of Kirbycide (jokingly called "Dededecide"). Another form of this attack is jumping off a high ledge and falling towards a side of the screen, then spitting an opponent out of the boundary lines.

Kirby will always lose in ''[[Super Smash Bros. Ultimate]]'' with a Swallowcide. Just like in ''Super Smash Bros. 4'', the opponent is released, allowing them to potentially recover back to the stage.

After grabbing, Kirby can force his victim into a SD by using a back throw at the edge of the stage.  The opponent has a chance to break out of the hold even after the throw is executed, the amount of time required depends on how much time was left from the grab, and can be broken out of quickly at low damage, or in some cases even without mashing if Kirby waits too long to throw.  The timing of Kirby's SD varies from character to character (and stage to stage), but Kirby often SDs after his opponent allowing this Kirbycide to be used to win a match. In Brawl, Kirby will not leave the stage when using this on the edge, getting rid of this form of Kirbyciding.  Even if performed on a quickly moving platform (e.g. the large moving platforms once [[Frigate Orpheon]] flips), the throw will end at the end of its animation, like any other throw, with Kirby simply stopping even if there is no ground beneath him.

The method of Kirbyciding with the forward throw is the same as the back throw; grab an opponent who is near the edge of the stage and leap over the side.  The forward throw is much harder to pull off compared to the back throw because the throwing animation is longer, giving the opponent more time to break free.  Kirby often SDs before the opponent with this Kirbycide. Again in ''Brawl'', this method was removed as with back throw.

Using the up throw to cause the opponent to SD requires Kirby to be at the very end of a ledge when he grabs.  If the conditions are correct (that of stage chosen and victim's character) Kirby will leap up as usual, but miss the stage on his way back down resulting in both players SDing off the bottom.  This Kirbycide is unique in the fact that the opponent ''cannot break free''.  However: Kirby ''will'' SD before the opponent, which ends the Kirbycide and gives the opponent a scant few frames to SD-Cancel. In ''Melee'' and ''Brawl'', this is not as detrimental as it seems because - aside from the strict timing requirement - many characters are incapable of recovering from the very bottom of deep stages, and some stages have hazardous environments - such as Jungle Japes' rushing water and lurking Klaptrap. However, in ''Smash 64'', the opponent will always be released just before being KO'd (while Kirby will always SD), and on stages like {{SSB|Dream Land}}, it is even possible for characters like another Kirby, Pikachu, and Luigi to recover. If used near the beginning of Rainbow Cruise or any time on Icicle Mountain, Kirby will hit one of the platforms above, causing both to die. There is also a glitch in Icicle Mountain that if the up throw is performed under a destructible ice block and there are only pass-through platforms underneath, Kirby will stop going up at the ice block, and fall through all the platforms underneath and cause both players to die.  In Brawl, the usual Up throw Kirbycide cannot be performed for the same reason as forward and back throws. The falling distance is fixed after the rise, so Kirby can fall a great distance off a ledge before actually finishing the move if he is stopped by a ceiling while rising up. This means the Up throw Kirbycide can still be used on stages with some sort of ceiling over a ledge, such as the lower center platform of [[Skyworld]] and the lower area of [[New Pork City]]. It can also be used on the lower-right area of [[Temple]]. The Kirbycide is almost the same as the original ''[[Super Smash Bros.]]'' and ''[[Super Smash Bros. Melee]]'', but the opponent dies at the same time as Kirby, preventing any SD-Canceling. Also, the up throw Kirbycide for Rainbow Cruise still exists in ''[[Super Smash Bros. Brawl]]'', but not in ''[[Super Smash Bros. Ultimate]]'', due to the upper platforms having their collision disabled when off screen. When using any type of these Kirbycides in Brawl, Sudden Death will occur. When an Up throw Kirbycide is used during a Sudden Death, the player with the greater controller priority in Brawl (P4 > P3 > P2 > P1) wins. Kirby's up throw can also be used to force both fighters into a hazard above them.

When using a Swallowcide in ''[[Melee]]'', Kirby will SD a fraction of a second after his opponent. In ''[[Smash 64]]'', ''[[Smash 4]]'' and ''[[Ultimate]]'', Kirby will SD before the opponent; and in ''[[Brawl]]'', both Kirby and the opponent will SD at the same time (causing a Sudden Death when both characters are on their last stock). If the opponent has no additional lives, Kirby will survive without losing a stock. If the opponent does have a stock in reserve, Kirby must immediately recover back to the stage by jumping, or he too will SD. Another method is pressing upwards on the directional pad when the enemy is too low to recover, and then float up to safety.
