Kracko

Kracko is a recurring boss who is a large cumulus cloud with one large eyeball and yellow spikes protruding from all sides. It first appears in Kirby's Dream Land. In each of its appearances, Kracko either releases electricity clockwise, dives across the screen, drops an enemy, or creates a hazardous rain shower.

Kracko typically first appears as Kracko Jr., who retains its large eye, although it is surrounded by four orbs. Kracko Jr. either spins its orbs rapidly or launches in different patterns. Kracko Jr. is either fought as a mini-boss earlier on or during the Kracko boss fight, right before transforming into Kracko itself. Mini-Kracko also starts off as a blob in a bigger cloud in Kirby's Dream Land 2, and fights mainly using Co-Krackos, who are small Krackos that Kirby can inhale.

Kirby's Dream Land
Kracko was the fourth boss, and is fought at the end of Bubbly Clouds. Kracko will drop Waddle Doos which Kirby can inhale and spit back for damage; swallowing them is also possible although useless, as this is one of the rare Kirby games not to feature the ability to copy powers. In Extra Mode, he moves faster and drops bombs.

Kirby's Adventure
Kracko is the fourth boss in Kirby's Adventure and its remake, Kirby: Nightmare in Dream Land. This time it was the boss of the stage titled Grape Garden. Kracko would drop Starmen enemies that Kirby could inhale for abilities.

Kirby's Pinball Land
Kracko is the boss of the Kracko Land pinball board, and starts out as a flying eyeball with small spheres encircling it. When Kirby hits it enough, it shows its regular form and floats around throwing out Flappers. It attacks the flippers by zapping them with lightning.

Kirby's Dream Course
Kracko appears as one of the courses in two player mode, occasionally shooting lightning at players that pass under him.

Kirby's Dream Land 2
Kracko must have both his forms battled back to back, the singular eye and the cloud. He drops Co-Krackos for Kirby to inhale and uses his usual electric attacks.

Kirby's Avalanche
Kracko is one of the characters the player challenges to a game of Avalanche.

Kirby Super Star
In Spring Breeze, Kracko is the third boss, and it retains his role from the original Kirby's Dream Land. Like the original game, Kracko attacks by dropping raindrops and streaking lightning bolts across the ground. His beam attack from the original game is also reused. He releases Waddle Doos, which give the player the Beam ability or can serve as ammo.

Kirby's Tilt 'n' Tumble
Kracko appears as the boss of Levels 3 and 5. Kirby uses the Gravity Balloon item to spit at Kracko many times with air bullets. Kirby must defeat Kracko before it fills up the entire area with Gordos; otherwise, it will dive-bomb him and knock him out cold regardless of anything. It is in Level 5 that Kracko starts shooting lightning.

Kirby's Dream Land 3
Kracko has a cameo as one of the paintings the boss Ado creates that comes to life. He acts similar to his appearance in Dream Land 2.

Kirby Air Ride
Kracko appears as a weapon in Top Ride, where it will shoot lightning bolts at players opposing the player who picked up the power-up.

Kirby & The Amazing Mirror
In Kirby & The Amazing Mirror, Kracko is the boss of Mustard Mountain. Besides its previous attack, Kracko also attacks by performing a spiral dive.

Kirby: Canvas Curse
Kracko was once again a boss, but not in the traditional sense. Kirby faces bosses in a series of mini-games in this installment. Before facing Kracko he must progress through a Breakout style mini-game, using paddles to send him ricocheting about. When fighting Kracko he must hit him and destroy his cloud cover, and then target the eye.

Kirby: Squeak Squad
While not technically the same, a new boss called Mecha-Kracko appears as a boss in this game. It looks and acts very much like the real Kracko. Created and piloted by the Squeaks member Doc, it is a machine with four yellow spikes and four holes that constantly spout smoke that covers the robot.

Kirby: Right Back at Ya!
In Kirby: Right Back at Ya!, Kracko appears in the episode "Dark and Stormy Knight."

It is bought by King Dedede from Nightmare Enterprises and attempts to give Kirby a jolt, but Tiff calls the Warp Star and Kirby rides into battle, becomes Sword Kirby, and defeats Kracko with a few Sword Beams which sliced Kracko in half, causing it to explode and the massive group of black clouds it comes with and hides out inside to disintegrate.
