Waluigi Pinossimo is a recurring character in the Super Mario Brothers franchise, primarily appearing in spin-off games such as Mario Kart, Mario Tennis, and various party games. Known for his tall, lanky appearance and trademark purple outfit, Waluigi is often depicted as Luigi's rival and Wario's partner.

His eccentric personality, scheming nature, and unique laugh make him a memorable character in the Mario universe.
