Crush Grip is a Normal-Type move introduced in Generation IV. Great force is used to crush the target. This move becomes more powerful if the target has more HP left, making the start of a battle or against a freshly-substituted opponent the best times to use this move.
Damage is calculated as follows:
Base Power = [110 * (Opponent's Current HP / Opponent's Maximum HP)]
