Infinite Dimensional Cape

Infinite Dimensional Cape is a technique in Super Smash Bros. Brawl. By repeatedly hitting up on the C-stick while holding down on the control stick immediately after entering the invisibility stage of Dimensional Cape. Meta Knight can stay invisible and invincible for as long as the C-Stick is being maneuvered properly. Note that the control stick must be held down constantly whereas the C-Stick is being pushed up repeatedly. When Meta Knight exits this infinite maneuver he will most likely attack, so he may be open for punishment after this if not used carefully. Should Meta Knight fall off an edge while using this technique, he will become helpless and unable to return to the stage, as he would if he were using a regular Dimensional Cape.

Due to the stalling capabilities of this technique, and the fact it offers a near perfect approach for Meta Knight, it has been recommended by the Smash Back Room that this glitch be banned in tournaments.
