The 'Captain Hydra' or 'Hail Hydra' meme stems from a shocking moment in the 2016 comic book Captain America: Steve Rogers #1, where the virtuous hero appears to reveal himself as a sleeper agent. The image of Steve Rogers whispering the infamous phrase gained a second life after the 2019 film Avengers: Endgame, which parodied the controversy in a tense elevator scene. In meme culture, the template is used to represent a person leaning in to whisper a controversial opinion, a shocking confession, or a traitorous secret that contradicts their public persona. Its versatility allows users to satirize everything from corporate politics to personal food preferences, making it a staple for anyone wanting to drop a hilarious truth bomb.
