- "I'm a princess, what are you?"
- ―Peter's Little Sister
Miss Maximoff is the informal name given to Ms. Maximoff's third child, the half-sister of Peter Maximoff/Quicksilver.
When Charles Xavier, Logan and Hank McCoy came to their house seeking Peter, she told Logan that she was a princess and asked what he was, to which he replied that he was "The Wolverine". He then asked the young Maximoff where her brother is, and she responds by pointing to the basement door, leaving Logan to crack a smile at her. After Logan, Charles, and Hank go to the basement Ms. Maximoff told her to go upstairs and bug her sister. She objects, pointing out that her sister bugs her, but Ms. Maximoff Points to the upstairs, which her youngest daughter complies to.
