Negative Zone

Negative Zone is Luigi's Final Smash in the game Super Smash Bros. Brawl for the Wii. It is a rather bizarre Final Smash, after Luigi breaks open the Smash Ball, he starts dancing around in a strange, almost hypnotic way. Then a large green circle appears on the stage, which takes up a large portion of the stage. Any opponents caught in this circle will be poisoned while the green circle is still on the stage, and will stay poisoned a little bit after the circle disappears. Then, while the green circle is in play, all characters in it become inverted in color, and can't move very well. Luigi, however, has full speed, giving him a clear advantage over his opponents for a short period of time. The effects wear off after a little while.
