Mt. Lady is a young woman who seems to enjoy the attention that being a hero gives her and she doesn't feel any shame from having to take that fame from another hero while basking in the glory. She is also shown to be quite vain as she uses her ample sex appeal to further her popularity or to gain something. This vanity also shows a bit of shamelessness, as she isn't above making a lewd pun about her own body. Furthermore, she also has a lecherous side. However, she is not careless, she will not transform into her giant form in confined spaces in fear of destroying nearby buildings and risk harming civilians as she is careful when fighting a villain who has taken hostages. Despite her vanity, she can be selfless when she needs to be.
