According to its profile, the Fortress is made from a special alloy that makes it highly resistant to physical damage, almost as if it is an actual fortress. It can be purchased from the shop for 750 Rings.
The Fortress is very much designed as a real-life racing motorcycle, with smooth and aerodynamic curves and a headlight on the front. It possesses a deep, highly polished red plating that covers it almost entirely, with thin orange highlights on the sides and an orange seat.
Abilities and traits
As a Bike type Extreme Gear, the Fortress is more powerful, but less maneuvrable than most Extreme Gears, and allows its rider to punch through obstacles and barricades.
When using the Fortress in a race, the player is invulnerable to damage, meaning that the player will not lose Rings when hit by other players' attacks, nor is the player affected by distraction-inducing attacks (such as the Octo-Ink). It cannot be equipped with any Gear Parts.
