Red has played a modest role as a part of Wendy's gang. She has been portrayed as the more confrontational of the girls at times, as demonstrated when she called Marjorine a geek and said: "she'd live alone for the rest of her life" at Heidi Turner's sleepover, and when she warned Wendy about the corrupted list of the cutest boys at South Park Elementary.

Red can also be benevolent at times; in some episodes she has been kind to many people and engaging in friendly conversations.
