ProZD, also known as SungWon Cho, is under fire for his stance on diversity in voice acting. In 2020, he supported race-based casting, arguing actors should match the race of their characters. But in 2023 he tweeted about being limited to only Asian roles, and in 2025 he was cast as a non-Asian character in Knights of Guinevere. Critics quickly accused him of hypocrisy, sparking a major online backlash and forcing him off Twitter.
