One of Luann's best friends. Delta is portrayed as a go-getter, demonstrated by how she attends dozens of clubs and activities every school year and takes part in volunteering. While Bernice is intellectually wise, Delta is the most politically intelligent in the strip, wanting to go into politics for a career. In 1998, Delta was diagnosed with Hodgkin's lymphoma. The following year, Delta received treatment and the cancer went into remission.

Delta graduated with Luann, Bernice et al from Pitts Junior/Senior High School in 2014 and went to Howard University. Except for an appearance where she wished Luann a happy 18th birthday, she has not appeared.
