Short answers, pulled from the story.
Ichigo Kurosaki was created by author Tite Kubo as the main protagonist of the Bleach manga series. He also appears in an anime television series, four anime films, two original video animations, rock musicals, several video games, light novels, and a 2018 live-action film.
Masakazu Morita voices Ichigo as a teenager in the Japanese anime, with Yuki Matsuoka playing the character as a child. Johnny Yong Bosch voices him as a teenager in the English dub, with Mona Marshall voicing the child version. Morita won the Best Rookie Actor award at the first Seiyu Awards in March 2007 for the role.
No. Tite Kubo originally intended Rukia Kuchiki to be the protagonist of Bleach. Through subsequent development, Kubo repositioned Rukia as a valued ally and introduced Ichigo as the central character. Early design sketches show Ichigo wearing glasses, with dark hair and softer eyes before Kubo gave him orange hair and a trademark scowl.
Ichigo was consistently ranked as the most popular character in Bleach in Weekly Shōnen Jump polls, though he dropped to third place in early 2008. He was also named best anime male character by the Society for the Promotion of Japanese Animation in 2008, and was ranked twentieth in IGN's Top 25 Anime Characters of All Time.
Critics found his climactic fights against Aizen and Ginjō anticlimactic, and the final battle against Yhwach was described as rushed by Anime News Network. Comic Book Resources noted a common fandom complaint that Ichigo is overpowered, constantly gaining new abilities with ease. Film School Rejects also criticized how Rukia was reduced to a weaker supporting role once Ichigo took the lead.
Sota Fukushi played Ichigo Kurosaki in the 2018 live-action film adaptation of Bleach, covering the storyline's first arc. Johnny Yong Bosch reprised his role as Ichigo's voice in the English dub of the film.
