Beam Kirby is one of Kirby's copy abilities. With the Beam ability, Kirby can fire a long range electrical whip from a magic rod and can also be charged up to fire a blast wave of energy. Beam Kirby is commonly obtained by inhaling the cycloptic Waddle Doo.
Waddle Doo can fire beams from his eye. Does that make you green with envy? Then inhale him and copy that ability! You'll then be able to shoot beams from a wand, and the attack can even be charged up for greater effectiveness. You can also use a beam to push switches or to grab and toss your foes.
Beam Kirby is one of the few copy abilities to get a Nendoroid from Good Smile.
According to Kirby Star Allies, Beam was the first copy ability, that Kirby ever obtained in the games' continuity.
Beam Kirby is said to be Masahiro Sakurai's favorite copy ability. As such it is often one of the first obtainable abilities in games.
Beam Kirby was the first copy ability to appear on the box art for a Kirby game, appearing prominently on the international box art for Kirby Super Star, which was also the first Kirby game to give copy abilities unique appearances.
