Gaea possesses great mystical powers of an undefined nature. Gaea can use any number of natural or magical effects as they pertain to the Earth itself.>Mystic Patron: Gaea can also bestow mystical power upon sorcerers who know how to call upon her for it.>Creative Force: Gaea is the embodiment of the spirit of life, growth, harvest, and renewal on Earth.>Eyes of the Beholder: Gaea does have a humanoid form, but she generally manifests herself in whatever humanoid form she chooses. Usually, she appears as a young woman with long black hair and blue eyes, but as Jord, she appeared as a young woman with blond hair and blue eyes. It has been suggested that she always appears in the form of however image she was worshiped as by whatever race on earth. So if she appeared before an ethnically diverse group, she would appear in the form of an ethnic image connected to that person such as African to a person of African descent and Asian to a person of Asian descent even simultaneously.>Power Bestowment: During Chaos War, Gaea granted Hercules some of her power in order to fight Mikaboshi. That power allowed Hercules to repair the multiversal damage done by Mikaboshi after his entrapment
In any of her humanoid forms, she has:
Superhuman Durability: Invulnerability to conventional injury and terrestrial disease. Shown most prominently when she was able to completely ignore an assault from all 4 original Defenders at once.
Allspeak: Thanks to the Allspeak she can communicate in all of the languages of the Nine Realms, Earth's dialects, and various alien languages.
It is difficult to gauge Gaea's strength level physically, as a non corporeal entity, her "strength" may range possibly Class 100 although she rarely relies on physical strength.
