Red is a complex character who exhibits both confrontational and benevolent traits. She is not afraid to speak her mind and can be confrontational at times, as demonstrated by her calling Marjorine a geek and warning Wendy about the corrupted list. However, she can also be kind and engaging in friendly conversations, as seen in her interactions with Jimmy in "Erection Day". She is not afraid to stand up for others, rushing to Butters' defense in "The Tale of Scrotie McBoogerballs".
