Dimensional Cape
Dimensional Cape is Meta Knight's down special move in both Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS / Wii U. When used, Meta Knight disappears and reappears, facing the opposite direction. By holding down the button Meta Knight attacks when he reappears, and tilting the control stick causes Meta Knight to reappear in that direction.
In Super Smash Bros. for Nintendo 3DS / Wii U this move can be customized with two unlockable variants. The first is Shield Piercer, which ignores shields but the teleport does not have as much distance and the move's overall power is decreased. The second variant is Stealth Smasher, which has greater distance but leaves him more open, since the attack makes him a moving blur rather than it being a near-instant teleport.
