Zone Speed

Zone Speed is one of the new confirmed shot elements with the Trick Shot, the Zone Shot, and the Special Shot for Mario Tennis Aces. When active, the world turns into slow motion. The player, however, is not affected and can run at normal pace, allowing them to reach any balls hit to the other side of the court they cannot reach at normal speed.

Zone Speed depletes energy when used, and therefore can only be used as long as the player has energy saved (similar to Zone Shots). Despite this, they are useful against the opponent's Special Shot or Zone Shot, as the player can time the block easier.
