Discharge

Discharge is the state that can enter during a match in Super Smash Flash 2.

Overview
Discharge activates whenever Pichu reaches 50% or more damage; once it does, its will release harmless electricity from its body while saying "Pichu!", and its idle animation changes, as if it is fatigued, and will release electricity from its cheek marks.

While in this state, Pichu's forward smash deals more damage and knockback, and its special moves become stronger and gain new traits; Electro Ball becomes slightly bigger and paralyzes the opponent for a much longer time, goes significantly farther, but cannot be charged, Agility produces an electric vortex after each dash, and  is stronger and propels Pichu upwards in its tumbling state so it can follow up with an aerial attack.

A drawback to this state, is that these amplified attacks also deal more recoil damage to Pichu when used, meaning it is easier to rack up damage at the risk of getting K.Oed much quicker.

Origin
Discharge is an Electric-type move introduced in Generation IV, which involves the user creating a wave of electricity that damages every Pokémon, except the user, in Double Battles, and damages all adjacent Pokémon in Triple Battles. It also has a 30% chance of paralyzing each of them. While Pichu cannot learn this move, its evolved form, Pikachu, can.

In SSF2, Discharge works differently, being a state Pichu enters once it reaches enough damage. Electro Ball's paralyzing effect while under this state may be derived from Discharge's chance of paralyzing its targets.

Trivia

 * This state is similar to the rage mechanic in, where the user's attacks get stronger as they accumulate more damage.
