The Bashosen takes the form of Jet the Hawk's signature twin weapons, the Bashōsens, which are said to have razor-sharp edges, both as an icon and on the tracks.
In gameplay, the Bashosen can only be obtained at random from Item Boxes by Jet. As with most other Items, Metal Sonic can also use the Bashosen if he uses the Steal Item to steal it from the aforementioned user.
Once obtained, the player can utilize the Bashosen by pressing its icon on the bottom of the HUD. When used, the user sets loose two Bashōsens that twirl around each other while they travel down the lane they were deployed on. As they move forward, the Bashosen will pass through any obstacle or enemy until it wears off. In addition, the Bashosen will leave behind a green trail while moving. Rival characters that make contact with either the Bashosen or their trail will take damage, causing them them to lose Rings and slow down momentarily. To avoid the Bashosen, the playable character has to step out of its lane.
The Bashosen can also be upgraded by leveling the user up to level 6 and 12 respectively. For each upgrade, the player will get the chance to obtain more Bashosens to use in the Boost Item slot from a single Item Box; at level 6, there is a chance of getting two Bashosens, and at level 12, there is a chance of getting three Bashosens.
