The Tail Strike takes the appearance of Tangle's tail.
In gameplay, the Tail Strike can be obtained randomly through Item Boxes with Tangle. As with most items in the game, Metal Sonic can also use the Tail Strike if he uses the Steal item to steal it from the aforementioned user.
Unlike other objects, the Tail Strike occupies two Item slots: one of a Projectile Item and the other of a Trap Item. When using the Tail Strike, the user will twirl and hit their opponents with their tail, in addition to obtaining a small turbo 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 in the same lane as the user. If an opponent is hit by the Tail Strike, they will lose Rings and be temporarily stunned.
Players can improve the effect of the Tail Strike by leveling up, although this will only affect one Item slot; After upgrading the character to levels 4, 8, and 16, they will be more likely to get two Tail Strikes in the Projectile Item slot, and if they are upgraded to levels 6 and 12, they will be more likely to get two Tail Strikes in the Trap Item slot.
To dodge a Tail Strike, opponents must simply move away from the user who is using it.
So far, the Tail Strike is the only Item in the game that can be stored in two Item slots with the same character.
