AMC's "The Walking Dead", Rick, Carl, Daryl, Morgan, Carol and Maggie were introduced to us in Season 1.

The answer is false because not all of the characters mentioned were introduced in Season 1 of AMC's The Walking Dead. While Rick Grimes, Carl Grimes, and Daryl Dixon were indeed introduced in the first season, Morgan Jones, Carol Peletier, and Maggie Greene did not make their appearances until later seasons. Morgan made his return in Season 3, Carol became a regular character in Season 2, and Maggie was introduced in Season 2 as well but became a main character in Season 3.
