In January 1990, Hammer won two American Music Awards for Favorite Rap/Hip-Hop Artist and Favorite Rap/Hip-Hop Album and was nominated for Favorite Soul/R&B Album ("Let's Get It Started"). The single "Let's Get it Started" also became the record that began the now-legendary rivalry between Hammer and LL Cool J. In the song's lyrics, Hammer braggadociously stated that he is second to none, in comparison to other rappers: ""And when it comes to straight up rockin’ / I’m second to none / from Doug E. Fresh to LL or DJ Run.”" LL Cool J would respond with "To da Break of Dawn," and revisit the rivalry years later with "I Shot Ya (remix)."

He is first introduced in a "Kakashi Chronicle" sidestory as a child soldier who sacrifices himself to save his friends (Kakashi Hatake and Rin Nohara, led by Minato Namikaze) from a rival group of ninjas. Although he was believed to have died, Obito is later revealed as the real leader of the terrorist organization, Akatsuki, mainly acting behind the scenes for a majority of the group's tenure. He uses the alias of his superior, Madara Uchiha, and conceals his true identity with masks as one of the primary antagonists in the series' second half. Obito and his varied personas have appeared in "Naruto" video games and animated adaptations. Kishimoto created Obito early in the series to explore his relationship with Kakashi and explain how his friend possessed the eye technique of , unique to the Uchiha clan. Since Obito kept his identity secret, Kishimoto teased fans to anticipate the true identity of Tobi (most notably when the actual Madara Uchiha was revealed, which shocked fans and his voice actor). Critical reception of Obito's character has been positive for his portrayal as a child soldier in Kakashi's backstory and his role across the series' manga and anime, particularly his fight scenes. Although Obito does not appear for the first time until the series' special chapters focused on his life as a child soldier, he makes a cameo appearance on the cover of the manga's 16th chapter in a picture with Kakashi Hatake.
