Skull Fire is a hoverboard that was first introduced in Subway Surfers World Tour: New York as one of the 4 new boards from the edition. It is a type of hoverboard that protects from crashing for 30 seconds. When crashed, the hoverboard will explode and need to recharge for a few seconds before using it again. It looks like a hoverboard a Grim/Death Reaper would use, with a picture of fire bursting out from the front part of the hoverboard on a black background.
Among all the hoverboards (excluding hoverboards with special abilities), the Skull Fire hoverboard is the most expensive board.
