Nerfs are weakening in Smash Bros games. That means an attack was not as strong as it was in the previous game. That is a nerf. Link's recovery, for instance, is a nerf as well as Mario in Super Smash Bros. Brawl. That means Mario in Super Smash Bros. Melee was stronger and better than he was in Super Smash Bros. Brawl. Captain Falcon, Ganondorf, and many more characters have been nerfed from Super Smash Bros. Melee to Super Smash Bros. Brawl. The most serious nerf is Ganondorf in SSBB who is last on the Tier List.
