The 'Where Is Omni-Man?' meme stems from the Amazon Prime animated series Invincible, specifically highlighting the frantic search for Nolan Grayson after his true intentions are revealed. It captures the tension of the Global Defense Agency, led by Cecil Stedman, as they realize Earth's greatest protector has become its greatest threat. In internet culture, the template is used to represent situations where someone important has suddenly disappeared, or to mock characters who are hiding in plain sight. Its popularity skyrocketed alongside the show's success, becoming a go-to format for fans of superhero subversion and high-stakes animated drama.
