King Dedede, the king of all Dreamland!..... Well maybe not king by blood. You see, one day Dedede thought,"Hey ya know what? I think I'm gonna be king of this place!" and just automatically declaired himself king! I wonder if anyone else knows he's the king besides him...>____>
Now that's not to say he's nesesserally a BAD king, or at least all around. He does tend to be very greedy and doesn't stop to think sometimes, but he does try his best at protecting his kingdom from dark or evil forces! So basically he's a jerk but a pretty decent guy!
He also has a grudge agenst Kirby who always triumphs over him, and as king he doesn't like being put at #2. So he tries to crush Kirby putting him in his place, or at least clear him out of the way of a situation.
Aside his giant hammer that can knock down a sky scrapper, King Dedede can also inhale and float like Kirby........ for some reason. His henchmen are mostly of the Waddle Dee/Doo species, but also alot of other creatures like Gordos, Bronto Burts, the Poppy Bros., Wheelies, Fire Lions, Scarfies, his giant Kabula blimp, etc.
And Waddle Doo is all like "...Yeah...I'm gonna go see what's over there..." *slips away*
