Inhale

Inhale is 's neutral special move in Super Smash Flash 2.

Overview
When performed, Kirby opens his mouth and inhales, sucking nearby opponents into his mouth. While an opponent is in Kirby's mouth, Kirby can walk around and jump with them for a short period of time before they escape automatically. Kirby can also spit them out as a star with the attack input, dealing 10% damage to the opponent. Most notably, he can swallow them with the down input or special input, dealing 6% damage to the opponent. By swallowing an opponent, he absorbs their neutral special move as a "Copy Ability" and can use it himself as his neutral special move instead. For each ability he has, he will gain a different hat allusive to the opponent he absorbed; obtaining 's cap, 's helmet, 's hair, etc. (see below for a complete compilation of revealed Kirby Hats). Once an opponent's neutral special move is acquired, the player can use a taunt to discard it and revert to Inhale. It will also be discarded if Kirby is KO'ed or damaged enough.

Origin
Inhaling and spitting has been Kirby's trademark attack since ', but it was not until ' that he was able to swallow an enemy to copy their attack.  introduced unique hats indicating different Copy Abilities. A single attack from an enemy or damage incurred from the environment was usually enough to make Kirby lose his Copy Ability, though later  games feature entire health bars instead of health points, so it is possible for him to occasionally keep his Copy Ability even after being damaged. After Kirby loses it, it takes the form of a star bouncing around the screen. Kirby can inhale and swallow it to regain the ability before it disappears after it contacts a hazardous surface or enough time passes.

Trivia

 * does not have this ability in the original Super Smash Flash due to Cleod9's inability at the time to properly code Copy Abilities. In compensation, he instead gave Kirby the ability to tag out with at any time.
 * This special move has given the developers a lot of work due to needing to sprite each hat to represent what power Kirby possesses. To go along with this, if something were to change to a character's neutral special move then the corresponding Copy Ability would have to change as well.
 * Also, when Kirby has a Copy Ability and performs certain complex animations (especially ones that cause Kirby to spin, like his up smash and his aerial side special), his hat will temporarily disappear and an Ability Star will hover around him until that animation is finished.
 * When copying Donkey Kong, Samus, or Mr. Game & Watch, Kirby's appearance differs from that of official Super Smash Bros. games due to the limitations of the engine not being able to accurately represent the originals, which covered his entire body.
 * When copying the Fighting Silhouette Team, Kirby will still gain the ability of the character the silhouette is mimicking despite the silhouettes not being able to use the special move copied themselves. This is unique among the Enemy Teams, whereas with those in the official Super Smash Bros. games, attempting to copy them would simply fail.
 * Prior to v0.3a of the demo, Kirby did not have a hat after he inhaled an opponent, plus he did not inhale the opponents at all; instead, he would inhale a small star from them.
 * Kirby is unable to use Inhale against characters during Transformation Final Smashes due to being immune to grabbing. However, prior to v0.5a, Kirby was able to suck them in and gain unique Copy Abilities from them. This was changed in order to prevent cheapness.
