Cupid is a heavenly ability that gives Kirby a whole slew of useful ranged attacks. Upon inhaling Cupie, Kirby gains feathery wings, a halo, a bow, and an endless supply of heart-shaped arrows.
Cupid Kirby can effortlessly fly around and shoot pointy arrows at enemies. The number of arrows Cupid Kirby uses is based solely of how long the player holds down the B button. The longer it is held, the more arrows Kirby uses. Unfortunately, the arrows fall to the ground after traveling a short distance. To make up for that though, Kirby is also able to angle his shots to make sure he can hit the enemy.
The ability's name was presumably changed to Cupid to avoid religious connotations; however, in Kirby: Triple Deluxe, the Cupid ability keychain is nevertheless known as Angel Kirby.
The hat Kirby gains from copying Pit and his attack with it in Super Smash Bros. Brawl resembles Cupid Kirby, complete with wings.
While this ability is represented as a keychain in Kirby: Triple Deluxe, it was retranslated to be closer to its Japanese name - Angel Kirby (although Cupie was not similarly renamed "Annie").
Cupid is one of two Copy Abilities in the Kirby series that grants Kirby a bow and arrows; the other is Archer.
Cupid, Mini, Smash Bros., Archer, Hypernova, ESP, and Staff are the only Copy Abilities whose names are different in Japan; in Japan, Cupid is Angel, Mini is Minimum, Smash Bros. is Sma Bro, Archer is Sniper, Hypernova is Big Bang, ESP is Esper, and Staff is Stick.
Cupid's name is one of two instances in the Kirby series where a Japanese name was changed in other countries to downplay religious connotations, the other being the Shadow Star (Devil Star in Japan) Air Ride Machine from Kirby Air Ride.
