Super Claw

The Super Claw is a power-up that appears in the PlayStation 3/Xbox 360 version of Sonic Unleashed. It can only be used by Sonic the Werehog. When the player obtains a Super Claw, Sonic the Werehog's attack power will be increased for a short time.

Description
The Super Claw closely resemble a metallic grey brass knuckle with four long and thin, but sharp, blades on the outward section. When touching the Super Claw in gameplay, Sonic the Werehog will glow with an orange aura and his attack power will be doubled, meaning he can deal twice the damage to the enemies with his attacks, for a limited amount of time.

The Super Claws can only be found in the game's Nighttime Action Stages, where they are hidden inside breakable objects throughout the Acts. To find them, the player has to hit and destroy the breakable objects.
