Guardian of Earth
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 rock and stone, create trenches, and cause avalanches and mudslides. In the animated series, Cornelia happens to the Guardian whose power happens to dwarf the others but ironically, her powers are useless when she is not near the ground or there are no plants to control.
The Guardians met Kadma, the former Guardian of Earth, when on an adventure in the dimension of Zamballa; Kadma had taught Cornelia the ability of green-speaking, the ability to communicate and sense the location of vegetation. Cornelia also has learned to manipulate certain types of metal that have a composition with a substantial amount of Earth in it.
When the Guardians recieved a power boost from when the Oracle and the Council of Candracar deactivated the Veil causing the power used to sustain and create it to flow back into the Aurameres, Cornelia gains the power of telekinesis, the power to levitate and manipulate objects with the power of her mind. With her telekinetic powers, Cornelia can not only hurl rocks at her opponents she can mentally throw objects such as flatware, trashcans, books, people, etc. She can levitate herself also to gain limited flight powers, can defend herself with a telekinetic barrier, and fire pulses of sheer telekinetic power.
She also gains a minor glamouring-shape shifting power to transform into herself but look like her Guardian self but without the wings, amplified powers or the costume but definitely the mature body and voice.
