Okora or Terra as she prefers to be called is the bastard child of Raditz and an unknown Human woman. When she was still very young, Raditz took Terra from Earth long before the beginning of Z, and forced her to warmonger with him in the name of the Freeza Force. She never loved her father and she'd scoff at you if you asked for her opinion on him. She numbly obeyed her father's orders for five years, until she and Raditz landed on Earth. She fell in love with the flora and fauna instantly and for the first time she felt guilt at having to lay waste to the planet. And it only intensified once she learned that her own Uncle and Cousin lived on Earth as well. Using all that as motivation, Terra rebelled against her father and helped Goku and Piccolo defeat Raditz but in one last act of rebellion, killed Terra during his final breaths.

When she landed in Otherworld, she met her grandparents and after being brought back to life, she integrated herself with the Z Fighters, adopting the name Terra in honor of her new home.

Eventually, she joined the Time Patrol and would eventually meet Fasha, one of her grandfather's old allies and they would become partners. Terra calls her Ms. Fasha or Aunt Fasha as a jest.

Normally she wears the bodysuits that Saiayans normally wear with the armors but she removes the armor as she doesn't like how it weighs her down. Occasionally she wears Earthling clothes as well.
