The Beam Sword (ビームソード, Beam Sword) is a long-range battering item, similar in appearance to a lightsaber. Available in all five games, it can be wielded and charged for melee attacks or can be thrown, like all other battering items.
The Beam Sword acts as a reference to similar weapons found in various science fiction media, most prominently the lightsaber from the Star Wars film series. The item's sound effects are similar to those found in lightsabers, including the distinctive swinging sounds and sharp crackling noise when two swords collide. These sound effects were modified in the PAL and American releases of Super Smash Bros. and all versions of Super Smash Bros. Melee to no longer resemble that of the lightsabers, but would be standardised to resemble the weapon in all regions from Super Smash Bros. Brawl onwards. Furthermore, starting with Melee, the Beam Sword's blade could retract in some animations, furthering the connection between the item and its source.
As a battering item, the Beam Sword will bolster the player's power, as well as potentially add some options to their game via throwing. In Melee and Brawl, the Beam Sword's range significantly increases in size, particularly in the case of charged smash attacks. In each of its subsequent appearances, its range has increased, with Brawl's variant of the weapon potentially having thrice the range of its Melee counterpart. With this, the beam of the blade can also pass through walls. In Super Smash Bros. 4, character-specific Beam Sword attacks, such as Marth and Roy's two-hit slashes, are no longer present.
The Beam Sword is one of few unusual items Peach can pull out via her Vegetable attack, though the chances of this are slim (1 out of 58 chance), and has been removed in Smash 4. In addition, the behavior surrounding the event is unorthodox for Brawl; in the first minute of plucking the item, the sword's range is severely decreased, as Peach will use her item throwing animation rather than her standard item swinging animation. After a minute, the item pickup sound will play and the Beam Sword regains its usual properties, though the player can also toss the sword and pick it up again to restore its proper attributes.
Equipping the Susie, Hal Emmerich or Isa Jo Support Spirits will give the player a Beam Sword at a start of a match.
With its distinctive glowing blade, the Beam Sword is eye-catching and lethal. At first, the blade is about the size of a short sword, but the length changes depending on who wields it. The blade also lengthens in direct proportion to the power of an attack, so it reaches its maximum size when swung as a smash attack.
A sword with a blade of glowing energy. The length of the blade changes depending on the fighting spirit of the wielder. It has four attacks: a standard attack, a strong side attack, a side smash attack, and a dash attack. When doing a side smash attack, the Beam Sword's blade grows to three times its normal length--that's the best reach of all battering weapons.
A powerful sword with a blade of pure energy. It isn't the strongest weapon to land on the battlefield, but its shape can change based on how it is used to attack. A forward smash will make the blade especially long. Lash out at your foes from a distance—they can't hit back!
The blade of this sword is made of pure light energy. It's not very powerful, but depending on your attack, it can have a pretty long reach! Just wait till you use it for a side smash! You can make the most of its power by attacking enemies as they're falling, or when you're too far away for them to counter-attack.
