Lishanne Davis was a popular girl. In the Sunnydale High Yearbook of the Class of '99, she was voted most attractive. In 1997, she tried for the school's cheerleading squad, incurring the wrath of Catherine Madison, who placed a magic spell on her causing her mouth to dissapear.
In the middle of biology class, Lishanne was seen shaking her head violently trying to scream but her cries were muffled. Buffy Summers was shocked to see that Lishanne's mouth was gone. The other students were frightened as well. However, after Buffy defeated Catherine, Lishanne's mouth was restored to normal.
Afterward, she succeeded in becoming part of the squad.
