Nerf

Nerfed is a term to describe the weakening of certain attacks of veteran characters when making a sequel. It is often done as an attempt to balance the roster. The best example of this is Kirby's transition from the original Super Smash Bros. to Melee. Kirby went from being one of the best (tier-wise) characters to being one of the worst.

For example: From SSBM to SSBB, Peach's forward throw and down smash have been weakened, and she cannot double-jump cancel anymore.
