Dede-Rush is King Dedede's Final Smash in Super Smash Bros. Ultimate, replacing Dedede Burst in Super Smash Bros. (Wii U and 3DS).


King Dedede uses his hammer and launches one opponent into a cage match. Then, they are suddenly hit by a few missiles before King Dedede (as his alter ego Masked Dedede) uses his jet hammer and slams them, sending them launching. This Final Smash does a massive amount of damage combined with high knockback, making it a move very easy to kill with at low percents.


During the Final Smash, King Dedede dons his mask to become Masked Dedede, his upgraded form from Kirby Super Star Ultra (specifically Revenge of The King), which would go on to be a fan favorite.

The caged ring is reminiscent of the arena in which Kirby fights Masked Dedede, and Dedede's New Dedede Hammer is used to fire missiles and perform Hammer Swing, both attacks used during his boss fight. In particular, the missile attack seems to resemble one of King Dedede's attacks from the breakout-esque spin-off Kirby's Block Ball.


  • This is the only one of King Dedede's Final Smash to have a clear origin in his home series.
  • The E3 build shows Masked Dedede having blue eyes as opposed to yellow.
