The 'FBI Open Up Thanos' meme is a high-energy mashup that blends the iconic tactical raid meme with the cinematic presence of Thanos, played by Josh Brolin, from Marvel's Avengers: Infinity War (2018). The 'FBI Open Up' audio originally surged in popularity around 2018, often paired with footage of SWAT teams breaching doors to catch someone in a compromising or illegal act. In this specific template, Thanos is seen reacting to the sudden intrusion, or the breach happens just as he is about to enact his grand plan. It captures the sheer panic and hilarity of being caught red-handed by authorities in a way that only a cosmic villain can. This clip is widely used to represent situations where someone’s 'cursed' search history, questionable life choices, or secret plans are suddenly exposed to the world. It perfectly illustrates the sudden realization that one's actions have immediate, explosive consequences. Example captions include: 'When you delete your browser history but the router remembers everything' or 'When you use the wrong math formula but somehow get the right answer.'
