Power Shields are weapons in Crash Team Racing and Crash Nitro Kart. They are green, spherical force fields that surround the player and prevent damage. In Crash Team Racing, pressing Circle will fire the power shield and if it hits another player, it will cause damage. For this reason, a second power-up cannot be used in CTR without first firing away the power shield.

Power shields can't be fired in Crash Nitro Kart. While wearing a power shield, if the player crashes into an opponent (or vice versa), the power shield will be destroyed and the opponent will take damage. After a certain amount of time, the power shield will fade away. Juiced up power shields are blue and will never fade away.
