Masked Dedede is a boss that appears in Revenge of the King. He is in Kirby Super Star Ultra. He is King Dedede, but his dinosaur mask makes him look like a whole different character. He looks much taller, and he has red boxing gloves. His hammer is now electric, and it can shoot flames. He can spin around with it, and this will cause tons of damage. After this, the dinosaur mask will come off and King Dedede will be dizzy, then return to normal. When he is defeated in battle and is sent flying, his voice is considerably lower than when he is launched in Spring Breeze.
