Which 1993 NES Kirby game first introduced Copy Abilities?

Kirby's Adventure is the 1993 NES game that first introduced Copy Abilities. By inhaling and swallowing certain enemies, Kirby could gain powers based on their abilities, transforming the way players explored and fought.

The feature was designed by HAL Laboratory director Masahiro Sakurai to add challenge and replay value after Kirby's Dream Land was criticized for being too simple. The team experimented with more than 40 possible abilities before selecting those included in the finished game.

Kirby's Adventure was the second Kirby game, following the 1992 Game Boy title Kirby's Dream Land. It is often confused with Kirby Super Star or Kirby 64, which expanded the ability system later but did not originate it. The NES game also established Kirby's first color appearance and introduced Meta Knight.
