Ron Weasley in the context of "Harry Potter"

Harry James Potter is the titular character of the Harry Potter series of novels by J. K. Rowling. The plot of the seven-book series chronicles seven years in the life of the orphan Harry, who, on his eleventh birthday, learns he is a wizard. He attends Hogwarts, a school of magic, where he receives guidance from the headmaster Albus Dumbledore and becomes friends with Ron Weasley and Hermione Granger. Harry learns that during his infancy, the Dark wizard Lord Voldemort murdered his parents but was unable to kill him as well. The plot of the series revolves around Harry's struggle to adapt to the wizarding world and defeat Voldemort.

Harry is regarded as a fictional icon and has been described by critics and publications as one of the greatest characters of all time. He is portrayed by Daniel Radcliffe in all eight Harry Potter films, and Dominic McLaughlin in the upcoming television series. Harry also appears in the play Harry Potter and the Cursed Child, which has been produced on stage since 2016.

Harry Potter is a film series based on the Harry Potter series of novels by J. K. Rowling. The series was produced and distributed by Warner Bros. Pictures and consists of eight fantasy films, beginning with Harry Potter and the Philosopher's Stone (2001) and culminating with Harry Potter and the Deathly Hallows – Part 2 (2011). A spin-off prequel series started with Fantastic Beasts and Where to Find Them (2016), marking the beginning of the Wizarding World shared media franchise.

A British and American co-production, the series was mainly produced by David Heyman, and stars Daniel Radcliffe, Rupert Grint, and Emma Watson as the three leading characters: Harry Potter, Ron Weasley, and Hermione Granger, respectively. Four directors worked on the series: Chris Columbus, Alfonso Cuarón, Mike Newell, and David Yates. Michael Goldenberg wrote the screenplay for Harry Potter and the Order of the Phoenix (2007), while the remaining films' screenplays were written by Steve Kloves. Production took place over ten years, with the main story arc following Harry's quest to overcome his arch-enemy Lord Voldemort.

Hermione Jean Granger (/hɜːrˈmaɪəni ˈɡreɪndʒər/ hur-MY-ə-nee GRAYN-jər) is a fictional character in the Harry Potter series of novels by J. K. Rowling. She first appeared in Harry Potter and the Philosopher's Stone (1997), as a first-year student on her way to Hogwarts. She becomes friends with Harry Potter and Ron Weasley after they save her from a troll in the girls' bathroom. Hermione often uses her quick wit, deft recall, and encyclopaedic knowledge to help her friends in perilous situations. Rowling has stated that Hermione resembles herself as a young girl, sharing similar insecurity and fear of failure.

Hermione has been immensely popular. The version of the character portrayed by Emma Watson in all eight Harry Potter films was voted the best female character of all time in a 2016 poll of Hollywood professionals conducted by The Hollywood Reporter. Arabella Stanton portrays her in the upcoming television series.

A supporting character, also known as a side character, is a character in a narrative that is not the focus of the primary storyline, but is important to the plot/protagonist, and appears or is mentioned in the story enough to be more than just a minor character or a cameo appearance. Supporting characters differ from minor characters because they have complex backstory of their own, desires, and emotions. While this is usually in relation to the main character, rather than entirely independently, developed supporting characters add layers and dimension to the story and the protagonist. These back stories can increase the plot or further develop the main character. Different supporting characters have different roles. Some common types of supporting characters include: love interest, antagonist, best friend, mentor, sidekick, comic relief, and caregiver. Each supporting character has their own role that advances the plot and brings about conflict. Often, supporting characters can cross over into different tropes. Some examples of well-known supporting characters include Watson in the Sherlock Holmes stories, Donkey in the Shrek films, and Ron Weasley in the Harry Potter franchise. No matter what type of supporting character, they all help the protagonist achieve their purpose, advance the story, or have personal growth. Supporting characters fit into three broad categories: supporters, antagonists, and informants.

Supporters include caregivers, love interests, comedic relief, and close friends. They are generally important to the protagonist, so they often become the target or victim to the antagonist. They also characterize the protagonist through dialogue and their relationship. They offer the protagonist aid, companionship, and physical or emotional help. Ron Weasley and Hermione Granger in the Harry Potter series are examples of supporters.
