Boomerang (SSB attack)
From the Super Mario Wiki
Boomerang is a special move performed by both Link and his younger counterpart, Young Link, and will be used by Toon Link in Super Smash Bros. Brawl. In Super Smash Bros., it was Link's Standard B move. In Super Smash Bros. Melee, it was replaced by the Bow as the Standard B move and became his Side B move. It is also Young Link's Side B move in Melee. In Super Smash Bros. Brawl, Link's Boomerang will be replaced by the Gale Boomerang, but the Boomerang returns as Toon Link's side special move. In the first Super Smash Bros. only, Kirby was able to use Boomerang if he sucked up Link's abilities.
Once the move is executed, Link, Young Link or Toon Link will throw a Boomerang sideways, which will hit a nearby opponent and then hit them again on the way back. The attack can also be moved slightly upwards and downwards. There are a few differences between Link's, Young Link's and Toon Link's versions of the attack. Link's can be thrown farther and does more damage, but lacks control. Young Link's cannot go as far as his adult counterpart's attack, nor can it do as much damage. However, Young Link is able to control it better, being able to tilt it up or down easier than Link. The difference between Link and Toon Link's attacks in Super Smash Bros. Brawl are the same as Link and Young Link's differences from Super Smash Bros. Melee, with the added effect that Toon Link's Boomerang doesn't wrap opponents up in a small twister.
