Inhale

Inhale is King Dedede's neutral B attack. Not to be confused with Kirby's inhale, where in he gains abilities from others, Dedede simply spits his victims out.

Actual gameplay footage shows that King Dedede can walk around with his victims in himself, and can perform "Dededecide" (also known as Regicide).

Much like Wario's Chomp, Dedede is able to swallow items using this attack.

Origin
In the Kirby games, Dedede has exhibited the ability to inhale foes or objects just like Kirby can. He can't, however, copy the inhaled person's abilities. For some reason, King Dedede was incapable (or simply never shown doing it) of "inhalating" in the Kirby: Right Back At Ya! anime (known as Kirby of the Stars in Japan).
