Greninja is a dual-type Water/Dark Pokémon introduced in Generation VI. This bipedal, frog-like creature resembles a ninja with dark blue skin, a yellow chest, white markings over its eyes, and a long tongue wrapped like a scarf around its neck. It compresses water into sharp weapons like shurikens, katanas, and kunai to slice through metal and confound foes with its rapid, graceful movements. Greninja excels in speed and reflexes, toying with enemies before striking decisively. Its Mega Evolution enhances these traits, allowing it to provoke attacks, bind opponents with its tongue, and overwhelm with a giant water shuriken. As the final evolution of Froakie, it embodies mastery and agility in battle.
