With this ability, Kirby wears a hat with jet-plane wings, with a big jet rocket attached on the back, and gets some shades on the front that drop down to protect his eyes. He uses this ability to hover for a long time and also get a speed boost while in midair. This ability also appeared in Kirby Super Star's Gourmet Race sub-game in the Onion Garden course. It can only be obtained through the third copy pedestal towards the start of the level.
Kirby charges up the jet's energy. It can be saved by jumping or guarding, allowing Kirby to move around freely; if Kirby gets hurt, he will lose his charge.
↑ + B (tapped)
Kirby does a quick moon kick that hits enemies from above.
This attack is exclusive to Kirby: Planet Robobot.
B or Y (tapped)
Kirby lunges forward, foot outstretched and kicks enemies, damaging them.
B or Y (tapped, midair)
Kirby dives forward, plowing through foes.
Kirby now tires out upon repeated use of uncharged Jet Headings. After five are used in rapid succession, he will travel half the normal distance with more gravity acting on him.
B or Y (tapped, full charge)
Kirby launches forward at high speed, ramming enemies. By pressing the B or Y button again, a powerful blast of energy is shot out from the jet and released through Kirby's arms. This is known as the "Jet Cracker".
Due to the changes in hitstun, Kirby can now hit all foes and bosses with both the dash and the Jet Cracker, which was not always possible in Kirby Super Star.
B or Y (tapped, not full power, near enemy)
Kirby sucks the enemy into his thruster and blasts it out the back, colliding with other enemies and dealing damage.
Captured enemies are thrusted much farther than they were in Kirby Super Star.
B or Y (tapped) + ←/→/↑ (full power, near enemy)
Kirby grabs an enemy, then loops around in an arched plunge before plummeting back down to the ground and violently kicking them away.
Enemies now fly erratically after being kicked away, rather than in a small arc.
Kirby's afterburn keeps him afloat in midair.
Kirby's vertical acceleration while hovering is much higher.
A (tapped, midair, full power)
Kirby launches himself into the air at high speed, using up the charge from his jetpack.
In Kirby Super Star, it is one of the techniques that can KO any mid-boss automatically when struck from below, due to the inexplicable "weak point" below the mid-bosses in the game. The weak point was removed in Kirby Super Star Ultra.
The Robobot Armor rapid-fires shots directly forward.
Hold B a little longer, and then release
The Robobot Armor fires two missiles forward.
Hold B even longer, and then release
The Robobot Armor fires four missiles; two normal missiles and one large missile forward and another large missile backwards.
A/Left trigger/Right trigger
The Robobot Armor boosts forward invincibly for a few seconds before moving back again.
Kirby: Right Back at Ya!
Jet Kirby in the anime looks the same as the game version, and can move faster than the speed of sound, making it his fastest ability. The only attack he is shown using is 'Jet Cracker'.
During the transformation sequence, a jet pack dashes past Kirby, spinning him. Coming toward him from the back, he runs toward the screen but it catches him and flips down shades.
Jet is obtained once when Kirby inhales a bike's exhaust port, and another time when he inhales part of a hot air balloon.
Jet transformation English version
Jet transformation Japanese version
Turn Kirby into a dangerous Jet. Store Jet power by holding Y. The more power you store, the more powerful the attack.
Strap jet power to your back! Hold the B Button to charge, then let go to hit Mach 5!
This high-flying ability full of aerodynamic power makes its return! Charge it up with B, and then jet toward enemies at extreme speed!
There's no escape from these wings. Lock on... Missile Salvo!”
