Super Dedede Jump
From the Super Mario Wiki
Super Dedede Jump is King Dedede's up special move in both Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U. The move is based on one of King Dedede's attacks when faced as a boss in the Kirby series. When used, King Dedede leaps into the air and slams down to the ground, damaging any enemies beneath him; hitting them as he falls acts as a meteor smash, and in Super Smash Bros. for Nintendo 3DS / Wii U landing on enemies on the ground buries them. Dedede also produces stars on both sides of himself as he lands which also damage nearby opponents. The player can angle Dedede's jump by holding left or right on the control stick as the move is executed. It is also possible to stop Dedede's fall by tilting down on the control stick in Super Smash Bros. Brawl or up in Super Smash Bros. for Nintendo 3DS / Wii U, though doing so puts him in a helpless state, and doing it closer to the ground causes Dedede to remain on the ground before returning to his feet.
In Super Smash Bros. for Nintendo 3DS / Wii U this move is given two customizable variants which can be unlocked. The first variant is Rising Dedede, which damages on the way up and leaves Dedede in a helpless state after he reaches the peak of his jump rather than descending. The second is Quick Dedede Jump, which is faster but does not get as much height or deal as much damage.
