Wall of Pain
A Wall of Pain is a term given to describe the ability to abuse the aerial attacks of certain characters, most often Jigglypuff, to create a seemingly impenetrable wall of high priority that pushes your opponents off the side of the stage horizontally. In Melee, Jigglypuff was the sole holder of the ability to perform this, although in Brawl, it is much less effective because of lower hit-stun, slower movement, and the ability for many characters to recovery in unfavorable conditions. Several characters also have similar abilities, such as Meta Knight, Kirby, King Dedede, and ROB. However, the ability of these characters to perform as well as the original Jigglypuff is debated.
