Cornelia Hale

The eldest daughter of a high-class family, Cornelia is somewhat a materialistic person, who cares a lot about her looks and fashion. In the comic/books Cornelia is annoyed and jealous that Will is the leader, and not her as she is better at leading than following, but after seeing the pressure and responsibility that is placed on Will's shoulders, she told Will that she will support her and that she deserved to be a leader. Cornelia is also overconfident and thinks she can do just about anything by herself. Still, she is deep down a considerate person who can be very romantic. She is not always the most positive person, but manages to get through obstacles with an attitude. She is also very firm and stubborn, and the least likely of the Guardians to accept or believe something, as was shown the very time that she learned that she became a Guardian.

Cornelia, as the Guardian of Earth, she can control plants and their growth and structure and manipulate the earth and all related materials such as paper, wood, silt, minerals, crystal, gems, sand, mud, some foods like sugar and wheat, silicon, molten rock, etc. At first she thought her powers are lame only consisting on making plants grow to giant sizes and altering their shape but she discovers her powers were much more: learning to create earthquakes, levitate and throw large slabs/chunks of rock and stone, create trenches, and cause avalanches and mudslides. In the animated series, Cornelia happens to be the Guardian whose power dwarfs the others, but ironically, her powers are useless when she is not near the ground or there are no plants to control.
