Kingler has an enormous, oversized claw. It waves this huge claw in the air to communicate with others. However, because the claw is so heavy, the Pokémon quickly tires. Its pincers grow peculiarly large. If it lifts the pincers too fast, it loses its balance and staggers. Its large and hard pincer has 10,000-horsepower strength. However, being so big, it is unwieldy to move.
