The Tail Strike takes the appearance of Tangle's tail making a spiraling forward movement.
In gameplay, the Tail Strike can be obtained randomly from Item Boxes by Tangle. As with most other Items, Metal Sonic can also use Tail Strike if he uses Steal to steal it from the aforementioned user.
Unlike other objects, the Tail Strike occupies two Item slots on the bottom of the HUD: the Projectile Item slot on the left and the Trap Item slot on the right. Once obtained, the player can utilize the Tail Strike by pressing its icon on the bottom of the HUD. When using Tail Strike, the user will twirl and hit their opponents with their tail, in addition to obtaining a small speed boost marked by a pale yellow panel on the ground. The afterimage when striking the opponent also appears to be pale yellow. The Tail Strike will hit all opponents who are nearby and on the same lane as the user. If an opponent is hit by Tail Strike, they will lose Rings and be temporarily stunned. To dodge a Tail Strike, opponents must simply move away from the user who is using it.
Players can also upgrade the Tail Strike by leveling the user up. When upgraded, the player will be more likely to obtain two Tail Strike to use in the Boost and Trap Item slots from a single Item Box. However, different levels will affect different Item slots; upgrading the character to levels 4, 8, and 16 will only affect probability of getting more tail Strikes in the Projectile Item slot, and upgrading to levels 6 and 12 will only affect probability of getting more tail Strikes in the Trap Item slot. At maximum level, the user can carry up to four Tail Springs in their inventory.
So far, the Tail Strike is the only Item in Sonic Forces: Speed Battle that can be stored in two Item slots with the same character.
