Funny and a little overweight, King Dedede is ready for fight! He is a "Superheavy" character (along with Charizard, Excitebiker and Bowser) but he is also a good (for his weight) jumper: he can do 4 jumps. He is a Brick character and he hasn't got a main element.
Standard Special: Gordo Toss King Dedede throws a Gordo which inflicts 16% of damage.
Side Special: Tambourine. King Dedede uses his tambourine as seen in Kirby Triple Deluxe Dedede's Drum Dash, and he will inflict 7% of damage.
Up Special: Super Dedede Jump. King Dedede jumps and falling he inflicts 18% of damage.
Down Special: Jet Hammer. King Dedede will charge his hammer and when he releases he will inflict from 11% to 20% of damage.
Final Smash: Masked Dedede. King Dedede takes his mask and he will be for 18 seconds. He is stronger and speeder than normal Dedede.
Meet him in Story Mode or complete Event 1: Two Trouble Kings (with Bowser).
