The Jet Hammer
is a move that can be performed by King Dedede
in Super Smash Bros. Brawl
and Super Smash Bros. for Nintendo 3DS and Wii U
. It is King Dedede's Down special. He will lift his hammer up, and it will open and turn into a engine. Holding it down too long will harm King Dedede
by 1% every half-second. In Super Smash Bros. for Nintendo 3DS and Wii U
however, he does not take recoil damage if he has 150% or more of damage.
