Titular character in the context of "Harry Potter (character)"

Gregory House is a fictional character and the titular protagonist of the American medical drama series House. Created by David Shore and portrayed by English actor Hugh Laurie, he leads a team of diagnosticians and is the Head of Diagnostic Medicine at the fictional Princeton-Plainsboro Teaching Hospital in Princeton, New Jersey. House's character has been described as a misanthrope, cynic, narcissist, and curmudgeon.

In the series, the character's unorthodox diagnostic approaches, radical therapeutic motives, and stalwart rationality have resulted in much conflict between him and his colleagues. House is also often portrayed as lacking sympathy for his patients, a practice that allows him time to solve ethical enigmas. The character is partly based on Sherlock Holmes. A portion of the show's plot centers on House's habitual use of Vicodin to manage pain stemming from leg infarction involving his quadriceps muscle some years earlier, an injury that forces him to walk with a cane. This dependency is also one of the many parallels to Holmes, who is portrayed as being a habitual user of cocaine and other drugs.

Doraemon (Japanese: ドラえもん) is the titular character of the manga and anime series Doraemon, created by Fujiko Fujio. Doraemon is a male robotic cat that travels back in time from the 22nd century to aid a preteen boy named Nobita.

Doraemon is considered to be one of the most popular manga and anime characters of all time. A birth certificate for the character gives him a birth date of 3 September 2112 and lists his city of residency as Kawasaki, Kanagawa, the city where the manga was created. In 2008, Japan's Foreign Ministry appointed Doraemon the country's "anime ambassador".
