The Fire Boost's icon takes the form of a fireball moving forward like a meteor. In gameplay, this power-up becomes a flaming orange aura that surrounds the user and leaves an flaming trail in its wake.
Once obtained, the player can utilize the Fire Boost by pressing its icon on the bottom of the HUD. When used, the Fire Boost will increase the speed of the user for a short amount of time. The duration of the Fire Boost is shown by the decreasing gauge on top of this power-up's icon on the bottom of the HUD whenever the Fire Boost is in effect. In addition, any rival character who makes contact with the user while the Fire Boost is in effect will take damage, causing them to lose Rings and slow down momentarily.
The Fire Boost can also be upgraded by leveling the user up to level 2, 8 and 14 respectively. For each upgrade, the Fire Boost will last longer.
