Moveset

Grounded Moves

Tap Kick Quickly press and release Y jet ability	Disjointed short kick that can hit twice Only available on ground Used for bossfights. (EX: Heavy Lobster, Whispy Woods, and Bonkers fights)

Jet Kick Hold Y, release before full charge jet ability	Kirby jet dashes forward and ends with a kick Has a fairly short ending animation, though still slower than jet dash chains Has a more disjointed hitbox than the midair jet moves, making it useful for charging through enemies with higher health (Knuckle Joe, Sword Knight, etc) Also can be used for spacing setups in certain areas (EX: mecheye screen 2)

Charge Moves

Advanced Techniques

Cancel Charge

Kirby can store his Jet charge by jumping, sliding, guarding, or climbing up a ladder in the middle of charging Jet.
Capsule J cannot cancel by sliding (he will jump instead).

Carry Momentum Underwater

By activating a tap jet (no dash) in the air while entering water at the same time as hitting a wall, the tap jet's X-speed will be maintained underwater.
Carrying X-speed is frame-perfect.
Y-speed will also be affected if there is wind blowing up or down in the room (ex. Halfmoon).
Carrying Y-speed has more frame leniency, but is still a tight window.

Avoid Unblockable Attacks

While charging Jet, Kirby is immune to attacks such as King Dedede's inhale or Combo Cannon's lasar beam.
This also happens when inhaling without an ability.

About Charge Value

When charging jet, the charge value increases by 1 every frame in RAM address ????.
The initial value of this address is 0, and this value stops increasing when Kirby stops charging. This value will continue to increase while Kirby charges, even at max charge, and will stop at 32767.
Below is a table that shows what RAM value corresponds to the Jet charge state.

Charge State	RAM Value
No charge	0 - 5
Mid charge	6 - 40
Max charge	41 - 32767

Glitches

Simultaneous Up+Down Bug

See KSS:Glitches#Simultaneous...

Jet Suplex

Score Bug

Defeating an enemy with Jet Suplex will reward double the Score originally intended.

Collision

Jet Suplex will ignore wind and water currents during its animation. This will last until you land and bounce backward.
Jet Suplex can also allow Kirby to clip through terrain during autoscrollers (See KSS:Glitches#Wallclips.

Other Information

Diving Rocket Collision

Diving Rocket has three hit detections: Kirby himself, the enemy he is holding, and the flames behind him.
Kirby's body is the same as Jet Dash, and the flame behind it is the same as when it is charging power.

Capsule J Air Jump

Normally, Capsule J cannot jump in the air. However, it can jump in mid-air while it is charging power.

Dash Jet Kick

Limited to Capsule J, you can perform a strong Jet Kick by pressing Y while dashing.

Capsule J Mid-Air Jet (Strong)

Capsule J has invincibility when using Strong Mid-Air Jet. This also applies if Capsule J bounces off a wall.
