Elphaba is the the daughter of Melena and Frexspar Thropp. Her father is Governor and as such, was horrified when his wife bore Elphaba, who had green skin. That different of anyone else in the family. He treated her differently, often putting her care upon the nanny. A year later, she had a younger sister by the name of Nessarose, who Elphaba took to looking after considering she would later not be able to walk. Despite that, she does her best to teach her how to look after herself in ways she can and not let people push her around. Which says something considering Elphaba does a bad job of letting people do that to her.

When Nessarose goes to Shiz, Elphaba expects to be staying at home. However, her powers that she was born with get out of hand. Madam Morrible applauds her and helps her enroll into the school and makes her her apprentice. She ends up being roomed with Glina Upland, a popular girl whom she doesn't much like, but puts up with. Things start off not so great for her as they always do. Elphaba is used to being the outcast and looked down upon, however, she's finding that her lessons with Madam Morrible make her feel like her magic is a gift and not a curse. 

When Glinda starts being nice to her, things start to change. She has a friend and a good one at that, though Glinda does still have her moments. The two bond more than she thought they would and it makes her wish they hadn't been so hostile at the beginning of the school year. Not only that, but other students are warming up to her as well, including the Prince. Fiyero goes out of his way to help her escape with the lion cub that was being demonstrated in class with a cage. Elphaba is horrified at what is happening to the animals in Oz and she finds she is like minds in that with Fiyro who covers for her when they get back to school. 

When Madam Morrible tells her she finally is getting the chance to see the Wizard, Elphaba takes the train, encouraging Glinda to go with her. Upon meeting the Wizard, she finds that things are not at all how they have seemed in Oz. The Wizard is no wizard at all and Madam Morrible is just as awful as him. After the two coerce her into using the Grimorie to transform the monkeys, they turn on her, making her out to be the villain. Elphaba makes an harrowing escape, having to leave Glinda being in the process. 

With Oz on the hunt for her, Elphaba goes out to the West, where she hopes to find support rather than hatefulness toward her for crimes she didn't commit.

• Elphaba turns Fiyero into the Scarecrow in order to protect him, with intentions of turning him back when they can be safe again.

• Glinda is left believing that she is dead. However, years later, she does get in touch with her again in hopes to reunite that friendship they'd once had.
