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 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, Wrench Rushes can only be obtained at random from Item Boxes by Wave.
When using this power-up in gameplay, the playable character will receive an increase in speed for a short time. Also, any opponent that gets too close to the user (even when they are on adjacent lanes) while Wrench Rush is active will take damage. Also, when a character is upgraded to level 2, 8 and 14, the Wrench Rush will last longer.
