The 'You Underestimate My Power' meme originates from the 2005 film Star Wars: Episode III – Revenge of the Sith during the climactic duel between Obi-Wan Kenobi and Anakin Skywalker. After Obi-Wan warns Anakin that he has 'the high ground,' Anakin arrogantly responds with this line before attempting a jump that leads to his defeat. The scene became a staple of Prequel Memes on platforms like Reddit's r/PrequelMemes, where it is used both seriously and ironically to represent hubris or a defiant stand against better judgment.
