Harry Potter is a character in the Harry Potter Musical Universe.
At age one, Harry beat the Dark wizard Lord Voldemort, who killed his parents. Harry was then sent to live with his cousin, uncle, and aunt, the Dursleys, on Privet Drive, who mistreated him and hid his magical ability.
When Harry turned eleven, he learned about his magic and was sent to Hogwarts School of Witchcraft and Wizardry, where he met his friends Ron Weasley and Hermione Granger, and spent an ordinary year learning shennanigans. He also acquired a large crush on Cho Chang.
In his second year, Harry returned to Hogwarts and met Ron's little sister, Ginny Weasley, who had a crush on him. At the start of term feast Harry learned that the Sorting Hat had married the Scarf of Sexual Preference, and so Dumbledore did the Sorting, putting anyone who "looked like a good guy in Gryffindor" and any body who "looked like a bad guy in Slytherin."
Professor Quirrell announced that the school was reinstating the Original House Cup, a deadly competition in which four champions competed, one from each House; Cedric Diggory, Cho Chang, Draco Malfoy, and Harry.
Meanwhile, Ron tells Harry that "backstage [he] saw some guys bringing in animals in cages", and when the trio investigates they learn that Harry must fight the Hungarian Horntail, and the other champions fight lesser dragons such as Figment the Imaginary Dragon and Puff the Magic Dragon. In the end, Harry puts the dragon to sleep by playing a song on his guitar.
Next, the school holds a Yule Ball, and, while there, Harry finds out that he's in love with Ginny, and the two dance. He also tries to steal Cho from Cedric, and the two get into a fight, Harry grabbing a punch ladel to hit him with, only to discover it is a Portkey and they are both transported to a graveyard, where Severus Snape brings Voldemort back to life, and calls together the remaining Death Eaters, including Bellatrix Lestrange, Voldemort's lover. Voldemort kills Diggory, and the Death Eaters blame Quirrell for the murder, and he is sent to Azkaban Prison.
Harry grabs the Portkey, returns to Hogwarts, and warns Dumbledore not to trust Severus Snape. Just then, the Death Eaters rush into the castle, and Draco Malfoy attempts to kill Dumbledore but fails, and so Snape does it for him. Shortly before he dies, Dumbledore tells Harry, Ron, and Hermione about Horcruxes, an object in which a Dark wizard stores a piece of his soul, and tells them that, to destroy Voldemort, they will have to destroy his Horcruxes, including one that is a Zac Efron poster.
Snape later saves the trio from death, and tells Harry he is the final Horcrux and must die.
Harry then duels Voldemort and wins.
