The 'I'm Fucking Invincible' meme features the antagonist Sundowner from the 2013 action game Metal Gear Rising: Revengeance. During his boss fight, Sundowner deploys his explosive reactive shields and shouts the iconic line, emphasizing his perceived untouchability. The phrase became an instant hit within the gaming community due to its sheer intensity and the character's over-the-top personality. Online, the template is used to depict situations where a person feels unstoppable, whether it is surviving a difficult exam, winning a debate, or simply being overconfident in the face of certain failure. Its popularity is bolstered by the 'Red Sun' boss theme and the enduring legacy of Metal Gear's meme-heavy dialogue.
