Wall-Luigi!
From the Super Mario Wiki
Wall-Luigi! is a Super Ability, used by Waluigi in Mario Strikers Charged. However, in order to use this move, Waluigi has to earn his special item, which is depicted as his head. When executed, Waluigi will be able to create Purple Vines behind of him, which act as a wall. This blocks off other players, which can protect Waluigi when charging up his Mega Strike. Wall-Luigi! actually makes Waluigi run faster. Although it is very hard, Waluigi can sometimes box himself in, meaning no one can reach him. This move can be very helpful, if used right. It was seen in the Opening Movie, for a brief moment.
