Dedede's moves are the same as they've always been. He'll try to hit Kirby with his hammer, float through the air, swallow Kirby or stomp on Kirby. He does have a new move where he'll summon a Waddle Dee though. Inhale the stars he produces and spit them back at him, or just use an ability. He shouldn't even be able to hit Kirby.

In the front she'll throw rocks and things at Kirby and Kirby can attack her. When she goes into the background Kirby can't reach her. She'll sometimes leap into the air and land in the foreground. Avoid her shadow so Kirby aren't crushed.

The best ability against her is Tornado. But then Tornado is the best ability against any boss. It's very, very broken, and makes it too easy! But if Kirby ever have trouble... just use Tornado.

Mecha Kracko has two stages with two life bars. The first stage is simple. He'll just bob up and down or pass slowly across the ground. He'll release Waddle Dees, Waddle Doos and Starmen that can be spit back at him.

In his second stage, first he'll destroy the cloud ground beneath Kirby and re-create it, only with gaps in it. He'll continue releasing enemies to be inhaled, only now he'll fire electric bolts down on Kirby. The gaps in the clouds make it a bit more difficult to avoid him if Kirby're trying to spit a star at him, so something like Hi-Jump or Tornado is useful.

It will use its clawed arms to move forward quickly, tossing bricks in Kirby's way. It also shoots fireballs along the ground that Kirby'll need to jump over. After its health gets low, the arms will break and its movement slows. Then the head will be destroyed, leaving it more or less defenseless.

Bohboh will fly slowly back and forth dropping fireballs, or quickly dash forward (you'll known when because he'll screech first) and grab Kirby in his talons, then tossing him into the lava. Other times he'll just fly back and forth quickly trying to hit Kirby.

If he dashes and misses he'll crash into the ground, causing rocks and enemies to fall. He'll be dazed for a moment, so it's a good chance to attack.

The stars he fires and the bombs can be inhaled and spit back. Otherwise, since he's often up in the air, a long range ability tends to be best. (Or Tornado.)

MK has all his old moves and a few new ones. He'll fly and create tornadoes, but now he'll occasionally shoot fire blasts from his sword, or slam it into the ground to create an electric field. He'll spin around sometimes to create stars that can be spit back at him, but he moves very fast and it can be hard to get to them.

Dark Zero will switch between three different elemental forms- Fire, Ice, and Electricity. Each one has it's own attacks, such as electricity creating an electric field on all sides of the screen, forcing Kirby to float in the center.

You can use the Triple Star weapon to beat this boss fairly easily.
