Who is Harry Potter and Albus Dumbledore's shared nemesis?
Albus Dumbledore Professor Albus Percival Wulfric Brian Dumbledore is a fictional character in J. K. Rowling's "Harry Potter" series. For most of the series, he is the headmaster of the wizarding school Hogwarts. As part of his backstory, it is revealed that he is the founder and leader of the Order of the Phoenix, an organisation dedicated to fighting Lord Voldemort.
Tweedledum and Tweedledee Tweedledum and Tweedledee are fictional characters in an English nursery rhyme and in Lewis Carroll's "Through the Looking-Glass, and What Alice Found There". Their names may have originally come from an epigram written by poet John Byrom . The nursery rhyme has a Roud Folk Song Index number of 19800. The names have since become synonymous in western popular culture slang for any two people who look and act in identical ways, generally in a derogatory context.
