Waluigi is a fictional character from the Mario series, created as a rival counterpart to Luigi. He is a tall, lanky, purple-clad anti-hero known for his sneaky, mischievous personality, exaggerated swagger, and competitive attitude. Waluigi often appears in spin-off games such as Mario Kart, Mario Party, and sports titles, where he serves as a recurring antagonist or comic rival rather than a main story character. He is closely associated with Wario and is often portrayed as scheming, dramatic, and unlucky.
