Jigglypuff (Super Smash Bros. Melee)

Overview
Jigglypuff is a hidden character in SSBM, unlocked by playing 50 VS matches. From the pokemon series, this puffball is a force to be reckoned with. It has 6 jumps, the best horizontal movement in the game, and a powerful down B attack. However, it is light and easy to KO, plus a bit on the slow side.

Pros

 * Superb horizontal recovery
 * Powerful Down+B attack

Cons

 * Slow all around
 * Easy to knockback
 * If you don't know Directional Influence, do NOT be Jigglypuff
