Poison

Poison is a status effect in Super Smash Flash 2 that causes the opponent to gradually take damage over a period of time. When this status is inflicted, green bubbles appear above the poisoned character.

Trivia

 * Prior to Beta, a speech balloon would appear alongside the green bubbles above a poisoned character. Said balloon hails from the  series.
 * This effect is similar and can be seen as an equivalent to the Flower effect in the  series.
