Wave's opponents might find this hard to swallow, but these fowl wrenches can deal damage across lanes as she flies past! — Description, Sonic Forces: Speed Battle
The Wrench Rush is an Item Box power-up that appears in the Sonic the Hedgehog series. It is a Boost Item used primarily to increase the user's speed.
Description
The Wrench Rush's icon takes the form of a regular-looking metallic gray adjustable wrench. In gameplay, this power-up becomes a white aura around the user, which has four gray adjustable wrenches circling around it.
In gameplay, the Wrench can only be obtained at random from Item Boxes by Wave and Tidal Wave.
Once obtained, the player can utilize the Wrench Rush by pressing its icon on the bottom of the HUD. When used, the Wrench Rush will increase the speed of the user for a short amount of time. The duration of the Wrench Rush is shown by the decreasing gauge on top of this power-up's icon on the bottom of the HUD whenever the Wrench Rush is in effect. In addition, any rival character who gets too close to the user (even when they are on adjacent lanes) while Wrench Rush is active will take damage, causing them to lose Rings and slow down momentarily.
The Wrench Rush can also be upgraded by leveling the user up to level 2, 8 and 14 respectively. For each upgrade, the Wrench Rush will last longer.
