Jet Hammer

Jet Hammer is King Dedede's side special move. When used, by holding down the special attack button, King Dedede charges up a jet-powered hammer swing; the attack gets stronger while the player charges, and the player is able to hold the charge indefinitely and move while charging, though a fully-charged Jet Hammer also damages Dedede for every second he holds it, though it stops damaging him at 150% in Super Smash Bros. Brawl and 100% in Super Smash Bros. for Nintendo 3DS / Wii U.

In Super Smash Bros. for Nintendo 3DS / Wii U this move is also given two custom variants that can be unlocked: Armored Jet Hammer and Dash Jet Hammer. Armored Jet Hammer gives Dedede super armor while charging but the attack deals less damage and it increases the damage he takes while charging. Dash Jet Hammer sends Dedede forward when he attacks but charging sends him back and the attack still deals less damage.
