Bowser is a fearsome, spiked-shelled Koopa with a formidable, dragon-like appearance. As the perennial antagonist in the Mario series, he is known for his ruthless plans to capture Princess Peach and conquer the Mushroom Kingdom. Bowser’s immense size, fiery breath, and powerful physical attacks make him a constant threat to Mario and his friends. Despite his villainous nature, Bowser’s complex character often reveals moments of grudging respect and even occasional cooperation with Mario.
