Super Dedede Jump
King Dedede jumps extremely high, then crashes down, dealing damage during the descent and when landing on the ground. The jump can be angled by pressing left or right while Dedede is turning to face the screen before he actually jumps, but once in the air, pressing left or right only changes the direction Dedede faces when he lands. He is vulnerable when he lands, so one can cancel the move by tapping down in Brawl or up in Smash 4 and Ultimate if it looks risky; this also allows the player to adjust Dedede's horizontal momentum. However, if it is done too close to when Dedede lands, he will become even more vulnerable; instead of just getting up, he will fumble around for about a second and a half before getting up, forcing delicate strategy when canceling the move. If Dedede hits a ceiling while using the move, he will fall helplessly.
Unlike most other up special recoveries in the game, this move does not auto-sweetspot the edge, except in Super Smash Bros. 4, but only during the upward jump. However, if the move is canceled close enough to the edge, Dedede will snap to it. It is also possible to use the Super Dedede Jump as an edgeguarding move.
During the first half of this attack (when he jumps into the air), King Dedede has armor, causing long attacks such as Smart Bomb to freeze King Dedede if he is hit during his armored frames. However, the jump deals no damage. If he hits an opponent as he is falling, it becomes a powerful meteor smash. If this move meteors an opponent onto the ground, and then Dedede lands on top of them, it has vertical knockback instead of the normal 45-degree angle. Stars are produced around King Dedede when he lands, produced in reference to the Kirby games. In Super Smash Bros. 4, Super Dedede Jump gained the ability to bury grounded opponents when landing on top of them.
Amusingly enough, if this move is used under a low-gravity effect (through certain stages, such as Pirate Ship and Spear Pillar, or through Special Brawl options), Dedede comes down at ridiculously slow speed and can travel absurd distances horizontally. This glitch can also work while Dedede is standing on ink in Super Smash Bros. Ultimate. By the same token, its utility as a recovery move is hampered by high-gravity effects, but it becomes much more difficult to avoid.
Super Dedede Jump is one of King Dedede's main attacks from the Kirby series, including his debut in Kirby's Dream Land. In the Kirby games, when Dedede jumps and lands, two stars would appear on each side of him, which Kirby could swallow and spit them back at King Dedede, though Kirby can't swallow the stars in Brawl.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
