Inhale is Kirby's signature technique. It involves Kirby sucking objects into his mouth like a vacuum, which stretches to fit large objects. Kirby can then swallow the object or enemy that is in his mouth to eat it, or spit it out as a star to attack. In most games, stars will sink in water (though in Kirby & The Amazing Mirror, Kirby: Squeak Squad, and Kirby's Return to Dream Land they will travel straight through water without sinking).
Many enemy characters have special powers that Kirby is able to copy once he's eaten them known as Copy Abilities.
Inhaling has no effect on excessively large or heavy objects, such as a boss.
The main difference between the games and the anime is that Kirby's regular inhale in the anime is equivalent to Kirby's super inhale in the games. Kirby's super inhale was absent from the anime. Also in the anime, before he inhales he holds his breath, screws up his face, does an "on the spot" run up, charges at the enemy, starts inhaling and steps backwards.
Inhale is a great defense as well as an attack, although it's impossible for Kirby to use while in yarn form in Kirby's Epic Yarn as the air inhaled goes right through his body.
Kirby cannot usually inhale underwater without the help of Kine, although he can in Kirby 64: The Crystal Shards. He can also move while inhaling in that game, something that is impossible in other games.
- Other members of Kirby's species have been shown to use this move as well.
- King Dedede has seemingly mastered this move as well, though he can't gain Copy Abilities.
- Rick the Hamster can both inhale and copy powers just like Kirby in Kirby's Dream Land 2, but in Kirby's Dream Land 3 he grabs objects and shoves them into his mouth.
- Gooey does not have Kirby's special inhaling powers, but uses his tongue in the same way that Kirby inhales.
- Whispy Woods also can inhale and tries to do so to Kirby and the other playable characters in Kirby's Return to Dream Land and Kirby's Dream Collection: Special Edition.
In Kirby & The Amazing Mirror and Kirby: Squeak Squad, Kirby can only inhale for a certain amount of time- but after inhaling for a while, it becomes a super inhale, which has slightly more range and strength, allowing him to inhale Large Enemies, Large Star Blocks, and Heave Ho Blocks.
In Kirby's Return to Dream Land and the New Challenge Stages in Kirby's Dream Collection: Special Edition, the Super Inhale becomes even more powerful. Kirby performs it if, while holding button 1, the player shakes the Wii Remote or presses the buttons on the Wii Remote's D-Pad repeatedly. It has further range, and allows Kirby to inhale the Heave Ho Blocks instead of moving them, as well as all enemies, 1UPs, food, and even other players, and spit them out as a Star; How large the star is depends on how many objects Kirby inhaled. Very large stars roll through enemies and only stop when they hit a wall.
Kirby: Triple Deluxe returns to the method seen in Kirby & The Amazing Mirror and Kirby: Squeak Squad, although he can Super Inhale indefinitely, similarly to Kirby's Return to Dream Land. However, it barely increases in range and doesn't have a noticeable impact in terms of power.
Super Smash Bros. series
Inhale is Kirby's and King Dedede's Standard Special in the Super Smash Bros. series, working much the same as it does in their own games. Kirby sucks up his foes, after which he can then spit out or swallow them. If he spits out an enemy, he/she will turn into a star (temporarily) that can be used to hurt others. King Dedede can suck in foes and also shoot them out, but can't swallow or inhale. His stars are more powerful though and his inhale has greater range.
Though Kirby can't defeat other characters directly by swallowing them, he can still copy their abilities and gains the use of that opponent's Standard Special Move, along with a hat that makes him look like that character (for example: inhaling Mario allows Kirby to use his fireball attack and has him wear Mario's hat). Any ability that Kirby copies will be weaker in magnitude from the original move however. For more information on what powers Kirby gets, see Super Smash Bros. Abilities. However, in the Subspace Emissary, standard enemies cannot be inhaled.
Kirby is immobile with an enemy in his mouth in the original Super Smash Bros. (aside from changing direction), but in Super Smash Bros. Melee and Super Smash Bros. Brawl Kirby can slowly walk around and even jump with a victim in his mouth, and may fall off of the stage and take his opponent with him. King Dedede, cannot move with his opponent, only being able to turn around.
In Super Smash Bros. for Nintendo 3DS and Wii U, Kirby can change his inhale using Custom Moves. Kirby can now also use Ice Breath or a Jumping Inhale. Ice Breath prevents Kirby from copying or spitting, instead freezing enemies that come in contact with is icy breath. The Jumping Inhale allows Kirby to inhale while lunging forward. However, exhaling a star won't deal damage. King Dedede can now also use Dedede Storm or Taste Test. Dedede Storm is an inhale that does repeated damage before launching opponents. Taste Test is a quick inhale that spits out opponents instantly.
