Miss Harper is Norbert Klerm's mother, personal secretary and advisor, usually the one to remind him of his responsibilities and put him in line.
Miss Harper sports a frilly red dress and high heels. She keeps her greying hair tied back.
Harper's role is not entirely clear, but she seems to know Klerm well seeing as she has to put up with his immature attitude and set him on the right track again.
Despite her best efforts to direct Klerm during his kidnapping and brain drain of Buzz Lightyear, to properly program his Slam Bots for marketing, she realizes that the entire plan has fallen apart, and quickly abandons her son to save her own life.
Miss Harper is very business-oriented and clear-headed, though frequently nags Klerm for his hasty decisions. It is unknown if she advises her son out of love or strictly business reasons, though she was quick to abandon him when she realized the situation had become unsalvageable.
- Miss Harper's name comes from what she does best, "harping".
- Miss Harper never explicitly refers to Norbert Klerm as her son; the revelation is only made when Klerm devolves into screaming "Mommy?!" after realizing she has abandoned him.
