Armando Thomas “Mondo” Guerra (born June 6, 1978) is a Mexican-American fashion designer who finished as runner-up on Season 8 of Project Runway, and later won the series' first season of "Project Runway: All Stars". Mondo also came out as HIV positive on the show.
Guerra was on the eighth season of Project Runway, aired in 2010. After placing in the top, but not winning, on a number of challenges, then placing in the bottom but not being eliminated in the seventh (Resort Wear Challenge) episode, he won the challenges on the eighth (Jacqueline Kennedy Challenge), ninth (L’Oreal Makeup Challenge) and tenth (HP Pattern Challenge) episodes.
During the tenth challenge, he revealed to the judges that his pattern of bright, bold plus signs on a pant was inspired by his HIV+ status, and that he had been keeping his HIV status a secret for ten years. He also won $20,000 for the ninth challenge, which involved both a “couture” look and a “ready-to-wear” look.
Project Runway Executive Producer Heidi Klum (who had pushed for Guerra to win over Jones in a lengthy  split debate over the winner) appeared in a modified version of one of Guerra's final collection gowns for the Los Angeles premiere of the movie Black Swan a few weeks after the airing of the final episode.
